Rock-munching sea urchins have self-sharpening teeth – Science Magazine

Andrew Martinez/Science Source

By Eva FrederickSep. 18, 2019 , 11:10 AM

Sea urchins spines arent the only sharp part of their prickly bodies. The sea creatures five razorlike teeth (above) are self-sharpeningand a new study suggests scientists may be able to harness this power to make cutting-edge tools that rarely require extra honing.

Sea urchins are well known for their ability to chomp through just about anything; they use their small, star-shaped mouths to crunch on brittle starfish, coral reefs, or even rocks. Scientists long suspected the urchins ceramic teeth sharpened themselves, but no one could figure out exactly how they did it.

To find out, researchers used scanning electron microscopy to film the teeth of pink sea urchins as they ground against a superhard material made of diamonds. After analyzing 3D movies of exactly how and where the teeth chippedand conducting multiple mechanical teststhe team found that materials in the teeth are arranged so that they chip only on one side. That helps them maintain a sharp edge all around, they report today in the journal Matter.

On the strong side of the tooth, resilient calcite fibers provide a supportive wall. On the other side, the calcite materials are arranged in brittle inclined plates, which chip away as the tooth scrapes against materials like starfish and rocks, leading to a constantly sharp edge. Sea urchins teeth continue to grow throughout their lives, so this wear-and-tear never wears the teeth down too far.

Knowing the material structure of sea urchins teeth could help researchers and engineers create drilling or cutting tools that could keep themselves sharp, the researchers say. It wouldnt be the first time sea urchins star-shaped mouths have informed the design of sophisticated toolsin 2016, their five teeth inspired engineers to create a clawlike scoop to help space exploration devices take sediment samples. Putting this new knowledge to use could give engineers of the future something to sink their teeth into.

Star Trek: 10 Crazy Borg Fan Theories That Were Actually Confirmed – Screen Rant

Gene Roddenberry's vision of a future where different species worked together for the goal of peaceful space exploration was the backbone of the Star Trek franchise. The perils on Earth -famine, disease, war, economic greed- had all been eradicated, leaving humankind capable of turning its attention to more noble causes. But there were those that opposed these ideals, and no villain ever posed as great a threat to the United Federation of Planets as the Borg.

RELATED: Star Trek: Picard Theory: The Borg Doomed Romulus

A mysterious collective of cybernetically enhanced beings first introduced in Star Trek: The Next Generation, they assimilated species optimal for their goal of genetic perfection. As they continued to advance across star systems, fans began to conceive of theories around what they had in store for the Star Trek franchise. As theories continue to speculate over the current relationship between Section 31's "Control"and the Borg inStar Trek: Discovery,here are 10 theories about the Borg that turned out to be true.

Click the button below to start this article in quick view

The first known existence of the Borg Queen was in Star Trek:The Next Generation,when Captain Picard was assimilated by the Borg Collective. More was learned about herin theVoyagerepisodes"The Raven" and"Dark Frontier". She claimed to be the "beginning and the end", an apex member of the Borg Collective designed to interface with other species, like the Queen of a bee hive, and an embodiment of their collective conscience.

While multiple queens were purported to exist,fans wondered if they would see them. Sure enough, betweenTNGandVoyagerat least two separate queens were confirmed, and many more mentioned by Seven of Nine, because when one dies another takes its place.

Some Star Trek fans accept that the there is no rhyme or reason for why the Borg Collective does what it does. Whether it's out of simple galactic domination or the pursuit of ultimate perfection, they assimilate species they think will best help them meet their goals and move on.

One explanation for the reason that they seem to appear and reappear throughout the Star Trek timeline is because of their pursuit of the Omega Molecule that Seven of Nine mentioned inVoyager.The Federation was able to synthesize it at least in part with Boronite Ore, and since it offers a nearly unlimited energy supply, the Borg desire it as well. Whether it fully explains their actions is up for debate, but it can certainly be added to the list.

Spock discovered inStar Trek: The Motion Picturethat V'ger was short forVoyager 6,the unmanned probe launched by NASA. When it landed on a machine planet, the inhabitants upgraded its tech and sent it back on its way. Ever since the Borg appeared inTNG,it was postulated by fans that they were the beings who accomplished this.

According to theStar Trek: Nerocomic series featuring the Romulan Nero from the Kelvin timeline, V'ger was drawn to his ship, specifically because it possessed Borg technology that had been reverse-engineered, which permitted it to speak to the crew.

While we first encounter the Borg inThe Next Generation,when Q flings the Enterprise-D into the Delta Quadrant to prove that humanity isn't ready for what lurks in the deepest, darkest corners of space, fans postulated that in order to have so many drones, the Borg had to have been at the assimilation game for hundreds of years.

In Voyager'sepisode "Dragon's Tooth", it's confirmed they're at least 900 years old.AndCaptain Archer encountered the Borg inStar Trek: Enterprise,when they assimilated a research outpost and he gave pursuit,so their operations proved to be long-standing and effective.

When the crew of the Enterprise-D encountered a young injured male drone while on an away mission in the episode "I, Borg", it prevented them with a tremendous opportunity. They could conceivably infect it with a virus and return it to its vessel, thereby allowing the virus to infect the entire Borg Collective once it rejoined the uni-matrix.

Picard effectively chose not to go this route, but instead imbue the drone (eventually named "Hugh") with that quality the captain values most; personal agency. With his newfound individuality, Hugh returned to the Collective and, as fans suspected, inspired several drones to escape and form their own miniature Collective elsewhere in the galaxy (albeit to varying degrees of success).

By now, most Star Trek fans have seen the countless teasers and trailers for CBS's newest Star Trek series coming in early 2020,Picard.It will follow Jean-Luc Picard 20 years after he left his captaincy of the Enterprise, seemingly putting his life with Starfleet behind him until the appearance of a mysterious woman and the circumstances surrounding their meeting draw him back in.

We see in the trailer that Borg cubes have become Romulan patrolled prisons, that Romulans have experimented on Borgs, and that they are seen as second class citizens. This seems to confirm the theory that in essence, all deactivated Borg drones are just assimilated victims, refugees that need guidance on how to reintegrate into the societies and cultures they were taken from.

After the encounter with the semi-autonomous drone Hugh inThe Next Generation, Voyager took the concept a step further and introduced the character of Seven of Nine, a drone that ended up having the large majority of her Borg cybernetic implants removed and becoming an integral part of theVoyagercrew. Her insider information about how the Borg functioned was integral in destroying most of their Collective.

Fans had theorized what happened to Hugh after the "I, Borg" episode, and he resurfaced in another episode ofTNGinvolving Data's evil brother Lore harnessing Borgs for his own nefarious end, but Seven of Nine finally proved what would happen to a Borg if they were completely rehabilitated.

RELATED:Star Trek: 10 Hidden Details About The Voyager Costumes You Didn't Notice

The plot included in the Season 3 cliffhanger "The Best of Both Worlds" Part I put Star Trek fans on the edge of their seat for a couple of reasons; one, Captain Picard (!) had just been assimilatedby the Borg,and two, they didn't know if that meant Patrick Stewart was going to return in Season 4.

Seasons 1 and 2 ofTNGhad been fraught with writing issues, the growing pains of any series in its first years, but Patrick Stewart was also known to get disgruntled with the cavalier treatment of the material. The head of Paramount Television even informed Stewart he was being written out of the series. Luckily, contractual issues were smoothed over, and Picard triumphantly returned.

In the Borg's quest for perfection, they assimilated countless life forms throughout the galaxy, including species 125, or humans. Fans wondered why humans were so desirable to the Borg considering the species propensity for free thought and individuality.

In the case of the Borg, the humans' commitment to individuality should have weakened them, but the Queen had a desire to re-assimilate her favorite drone, Seven of Nine inVoyager,precisely because she had learned to be both an individual and a part of the Voyager crew.

The Borg might have continued their relentless pursuit of perfection by assimilation throughout the galaxy had Q not done Picard an ironic solid and showed him and the crew of the Enterprise exactly what lurked in the furthest reaches of the Delta Quadrant. But why is it that every time the Borg encountered the Enterprise they seemed to allow their defeat?

The theory goes that the Borg allowed themselves to be defeated so that they could farm the Federation technology. Every time they faced the Enterprise again their technological advancement was apparent. It also explained why they only sent one ship inStar Trek: First Contact.

Philippine Space Agency – INQUIRER.net

Finally, we have a Philippine Space Agency (PhilSA), with President Duterte signing a law on Aug. 8 creating that agency. Some P2 billion in initial funds will be allocated, and the Clark Special Economic Zone has been identified as the site for the agency, with an area of 30 hectares.

PhilSA will be directly under the Office of the President, managed by a Philippine Space Council with the president as chair and with two vice chairs: the secretary of science and technology and the secretary of national defense. Other government agencies will be represented in the council.

The goal set for PhilSA is to make the country space-capable and space-faring by 2022. I know that the space-faring angle seems ambitious, but we shouldnt dismiss that possibility too quickly, considering that there is so much international cooperation now for space research, and there has been one Malaysian astronaut, Dr. Sheikh Muszaphar Shukor Al Masrie, who joined an international team at the International Space Station in 2007. Sheik Muszaphar is not just an astronaut but also an orthopedic surgeon and a part-time model. Yes, he has celebrity status in Malaysia.

A Wikipedia entry reports 72 government space agencies worldwide, with six (the China National Space Administration, Indian Space Research Organization, Japan Aerospace Exploration Agency, National Aeronautics and Space Administration [US], the European Space Agency and the Russian Federal Space Agency) having full launch capabilities.

China has been the most ambitious with its space programs, with its own spacecraft and space stations. The Chinese have 11 astronauts (9 men and 2 women) who have been sent into space. India was in the news recently with its moon lander, which unfortunately slammed into the moon rather than achieving a soft landing.

In Southeast Asia, our neighbors have been ahead of us in establishing space agencies. Indonesias National Institute of Aeronautics and Space (Lapan in Indonesian), for example, dates back to 1963. Lapan was more oriented toward military use, developing rockets for the Indonesian air force.

Southeast Asian space agencies are oriented more toward the use of satellites, again with Indonesia launching its Palapa satellite as early as 1976. The National University of Singapores Centre for Remote Imaging, Sensing and Processing (CRISP) and Thailands Geo-Informatics and Space Technology Development Agency (GISTDA) are also mainly involved in processing data from satellites.

Reading about CRISP and GISTDA got me thinking about our own University of the Philippines (UP), which is playing a major role in developing the countrys space program. It was UP Dilimans engineering and science faculty and graduate students, working together with Japanese universities and the Japan Aerospace Exploration Agency, that launched the satellites Diwata-1, Diwata-2 and Maya-1, with more in the pipeline. These satellites have been sending vital information important for weather forecasting, agriculture, land use planning, disaster risk management and defense.

The Department of Science and Technology (DOST) has, in the last nine years, spent some P7.5 billion for space research, including laboratories and a recently inaugurated ULyS3ES (pronounced Ulysses), which means University Laboratory for Small Satellites and Space Engineering Systems. Calling it a laboratory is being modest, with ULyS3ES consisting of two multi-storied buildings.

At the inauguration, I reminded the audience that our space program needs to harness all disciplines, including the arts. I was actually quite happy our scientists thought up satellite names like Diwata and Maya and now ULyS3ES and, wait, theres also STAMINA, for Space Technology and Applications Mastery, Innovation and Advancement (STAMINA4Space), which is training scientists from all over the country for our future in space. The names reflect creativity, and also the technical expertise of Joel Marciano Jr., a UP professor currently seconded to the DOST, and his team.

We might want to look to China for the way it taps into culture to make its space programs resonate with its citizens. Its lunar exploration program, for example, has a logo that takes off from the Chinese character for the moon. It is a stylized lunar crescent with two footprints in the center. That lunar program is also called Chang-es Project (Chang e gongcheng), after the folkloric moon goddess Chang-e.

Folklore and the arts aside, we should be looking at the politics behind space programs. All space programs have a strong element of national pride. In the 1960s, the US and the Soviet Union fought out their Cold War trying to outdo each other in space exploration. Now, its the Chinese and the Indians. National pride aside, give it to the Chinese, practical business people, who are looking to the moon for rare metals.

Happy Moon Festival again.

JFK started it; Texans have made it happen. [Opinion] – Houston Chronicle

More than half a century ago, President John F. Kennedys 1962 speech at Rice University rocketed Texas and the city of Houston to the center of human space exploration. Texans eagerly accepted that mantle of leadership and through their fortitude and fearlessness have proven irreplaceable to our rapidly accumulating technological and scientific prowess. America will rely on this same determination and expertise as we launch a new era of daring exploration and discovery in the 21st century.

This years 50th anniversary celebration of Apollo 11s historic moon landing would be incomplete without recognizing President Kennedys bold vision. His speech and Texans enthusiastic response to the moonshot challenge enabled our nation to accomplish what was previously thought impossible.

On that sweltering September day, 57 years ago, Kennedy reminded Americans that technological triumphs throughout human history happen only by confronting the most daunting challenges. The breathtaking pace of innovation in the 20th century was always commanded by those with answerable courage to tackle the most difficult problems.

So, why go to the moon? Simple, Kennedy answered unequivocally, We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills.

Fittingly, Kennedys Sept. 12 speech was delivered during Rice Universitys freshman orientation day. Nearly all of the approximately 40,000 people in the audience were college students or Texas school children bused in from the surrounding region. As a Rice University alumnus , I am very familiar with the academic dedication and unrelenting determination of young Texans. In speaking to Americas youth, Kennedy not only inspired scientists of the day but also future engineers, astronauts, researchers, mission control chiefs, operators and every other conceivable profession necessary to slip the bonds of gravity.

Kennedys confidence that America could land men on our closest cosmic neighbor is remarkable, and it proved prophetic. Lunar rendezvous are extremely difficult, even today, yet we landed Apollo astronauts on the moon not once, but six times, and in no small part because of highly qualified Texans.

Over the last five decades, billions of federal, state and private funds have made Texas into a scientific and engineering community second to none. To date, more than 10,000 Johnson Space Center civil servants and contractors work in Texas, with more than $2 billion spent on contracts and salaries during the 2018 fiscal year. Additionally, the International Space Station, humanitys largest space endeavor, is managed at Johnson. It is a pleasure to work with committed congressional leaders from Rep. Eddie Bernice Johnson of Dallas to Rep. Brian Babin of Woodville to Sens. John Cornyn and Ted Cruz who are so passionate about space. NASA knows it can always rely on Texas!

The deliberate and daring leadership of the 1960s taught us that we must courageously challenge the limits of our understanding. Like Kennedy, President Donald Trump understands that for the United States to continue to be a leader among nations, we must spearhead humanitys scientific and technological advancement by taking on the toughest challenges. NASA is fervently executing President Trumps directive to return to the moon and remain there and then take humanitys next giant leap to Mars.

The Artemis program named after the twin sister of Apollo, the Greek goddess of the moon will send the first woman and the next man to the moon by 2024. Texans vast experience and significant role in Americas space supremacy will again be pivotal in accomplishing this goal.

This 21st century lunar landing will be very different and more challenging than anything we have done in the past. In collaboration with commercial and international partners, we will construct a self-sufficient life-supporting architecture at the moon by 2028 so we can learn how to live on another world. This ambitious, new era of deep space exploration is increasing Johnsons responsibilities more than ever before.

Johnson is managing the development of the Orion space capsule that will once again send American astronauts into deep space. Additionally, NASA will rely on Texans human spaceflight expertise to develop a new lunar orbiting outpost called, Gateway. This platform will give us access to all parts of the moon and its resources. What we learn from Gateway will directly assist our future human missions to Mars.

Over five decades ago at Rice Stadium, Kennedy acknowledged the difficulty rising generations of young Americans would encounter in accomplishing the Apollo programs goal. But, he believed the challenge would bring out our best. I am confident that as the Artemis generation likewise continues to push on the boundaries of our scientific knowledge, we will broaden our technological horizons to benefit all of humanity in ways we cannot yet imagine.

Bridenstine is administrator of the National Aeronautics and Space Administration (NASA).

Effects of space on the body: Level 2 transcript – CBC.ca

Audio from 2009 NASA video: You can see the parachute coming down

Vik Adhopia / CBC News:It was a landing that felt like a crash, but for Canadian astronaut Bob Thirsk, that wasn't the worst part.

Robert Thirsk / Former Canadian astronaut: I felt like a wet dishrag on landing day.

Vik Adhopia: In space, astronauts' bodies go through an unearthly ordeal. They work out daily to counter the effects of low gravity on their muscles, but it's never enough.

Robert Thirsk: They wanted exercise, do thatlittle bit of extra exercise, so that I wasI was theIronmanon landing day. Didn't happen. Weightlessness takes a toll on the human body.

Vik Adhopia: Researchers are getting a better idea of how much of a toll. This lab works with volunteers and astronauts, developing new technologies, measuring the damage caused by weightlessness, pushing blood upwards to the head.

Richard Hughson / University of Waterloo: And we found that arteries get stiffer by quite a bit while they're in space. In fact, in six months in space, the arteries get stiffer by the equivalent of about 20 years of aging.

Vik Adhopia: With the muscle and artery damage in space also comes changes to bone marrow, which is being studied by another Canadian team.

Dr. Guy Trudel / University of Ottawa: So, it kind of reverses your normal forces of gravity. It's not like being in space, but it's a good model for it.

Vik Adhopia: This doctor is trying to counteract that effect by working with German researchers on this: a centrifuge that spins test subjects. It creates a pole, similar to gravity, and exercising while spinning counteracts the effects of low gravity. You may have seen the concept before, in the movies, which is not far off from what might be our reality.

Dr. Guy Trudel: So, if the studies that we're carrying (out) in Germany now are conclusive, that could well be part of the design of the future spacecraft to Mars.

Vik Adhopia: Artificial gravity won't solve all the problems of longer space travel. There's still the extended exposure to solar radiation and also the unknown cognitive and psychological effects of spending more time in space. Astronauts' bodies will have to endure a lot.

Dr. Guy Trudel: We need to build up a bit more knowledge before we can send people to Mars. We do not know if the damage will continue to progress at the same rate, or if there's gonna be a plateau at one point.

Vik Adhopia: As space exploration takes astronauts deeper into the galaxy, it'll open up new frontiers, not just for human travel, but for human health.

A Brief History of Space Exploration | The Aerospace …

Humans have always looked up into the night sky and dreamed about space.

In the latter half of the 20th century, rockets were developed that were powerful enough to overcome the force of gravity to reach orbital velocities, paving the way for space exploration to become a reality.

In the 1930s and 1940s, Nazi Germany saw the possibilities of using long-distance rockets as weapons. Late in World War II, London was attacked by 200-mile-range V-2 missiles, which arched 60 miles high over the English Channel at more than 3,500 miles per hour. After World War II, the United States and the Soviet Union created their own missile programs.

On Oct. 4, 1957, the Soviets launched the first artificial satellite, Sputnik 1, into space. Four years later on April 12, 1961, Russian Lt. Yuri Gagarin became the first human to orbit Earth in Vostok 1. His flight lasted 108 minutes, and Gagarin reached an altitude of 327 kilometers (about 202 miles).

The first U.S. satellite, Explorer 1, went into orbit on Jan. 31, 1958. In 1961, Alan Shepard became the first American to fly into space. On Feb. 20, 1962, John Glenns historic flight made him the first American to orbit Earth.

Landing a man on the moon and returning him safely to Earth within a decade was a national goal set by President John F. Kennedy in 1961. On July 20, 1969, astronaut Neil Armstrong took one giant leap for mankind as he stepped onto the moon. Six Apollo missions were made to explore the moon between 1969 and 1972.

During the 1960s, unmanned spacecraft photographed and probed the moon before astronauts ever landed. By the early 1970s, orbiting communications and navigation satellites were in everyday use, and the Mariner spacecraft was orbiting and mapping the surface of Mars. By the end of the decade, the Voyager spacecraft had sent back detailed images of Jupiter and Saturn, their rings, and their moons.

Skylab, Americas first space station, was a human-spaceflight highlight of the 1970s, as was the Apollo Soyuz Test Project, the worlds first internationally crewed (American and Russian) space mission.

In the 1980s, satellite communications expanded to carry television programs, and people were able to pick up the satellite signals on their home dish antennas. Satellites discovered an ozone hole over Antarctica, pinpointed forest fires, and gave us photographs of the nuclear power plant disaster at Chernobyl in 1986. Astronomical satellites found new stars and gave us a new view of the center of our galaxy.

In April 1981, the launch of the space shuttle Columbia ushered in a period of reliance on the reusable shuttle for most civilian and military space missions. Twenty-four successful shuttle launches fulfilled many scientific and military requirements until Jan. 28,1986, when just 73 seconds after liftoff, the space shuttle Challenger exploded. The crew of seven was killed, including Christa McAuliffe, a teacher from New Hampshire who would have been the first civilian in space.

The Columbia disaster was the second shuttle tragedy. On Feb. 1, 2003, the shuttle broke apart while reentering the Earths atmosphere, killing all seven crew members. The disaster occurred over Texas, and only minutes before it was scheduled to land at the Kennedy Space Center. An investigation determined the catastrophe was caused by a piece of foam insulation that broke off the shuttles propellant tank and damaged the edge of the shuttles left wing. It was the second loss of a shuttle in 113 shuttle flights. After each of the disasters, space shuttle flight operations were suspended for more than two years.

Discovery was the first of the three active space shuttles to be retired, completing its final mission on March 9, 2011; Endeavour did so on June 1. The final shuttle mission was completed with the landing of Atlantis on July 21, 2011, closing the 30-year space shuttle program.

The Gulf War proved the value of satellites in modern conflicts. During this war, allied forces were able to use their control of the high ground of space to achieve a decisive advantage. Satellites were used to provide information on enemy troop formations and movements, early warning of enemy missile attacks, and precise navigation in the featureless desert terrain. The advantages of satellites allowed the coalition forces to quickly bring the war to a conclusion, saving many lives.

Space systems continue to become more and more integral to homeland defense, weather surveillance, communication, navigation, imaging, and remote sensing for chemicals, fires, and other disasters.

The International Space Station is a research laboratory in low Earth orbit. With many different partners contributing to its design and construction, this high-flying laboratory has become a symbol of cooperation in space exploration, with former competitors now working together.

The station has been continuously occupied since the arrival of Expedition 1 in November of 2000. The station is serviced by a variety of visiting spacecraft: the Russian Soyuz and Progress; the American Dragon and Cygnus; the Japanese H-II Transfer Vehicle; and formerly the Space Shuttle and the European Automated Transfer Vehicle. It has been visited by astronauts, cosmonauts, and space tourists from 17 different nations.

Space launch systems have been designed to reduce costs and improve dependability, safety, and reliability. Most U.S. military and scientific satellites are launched into orbit by a family of expendable launch vehicles designed for a variety of missions. Other nations have their own launch systems, and there is strong competition in the commercial launch market to develop the next generation of launch systems.

Modern space exploration is reaching areas once only dreamed about. Mars is focal point of modern space exploration, and manned Mars exploration is a long-term goal of the United States. NASA is on a journey to Mars, with a goal of sending humans to the Red Planet in the 2030s.

NASA and its partners have sent orbiters, landers, and rovers, increasing our knowledge about the planet. The Curiosity Rover has gathered radiation data to protect astronauts, and the MARS 2020 Rover will study the availability of oxygen and other Martian resources.

Space Exploration - ABC News

European Space Agency – Wikipedia

The European Space Agency (ESA; French: Agence spatiale europenne, ASE;[4][5] German: Europische Weltraumorganisation) is an intergovernmental organisation of 22 member states[6] dedicated to the exploration of space. Established in 1975 and headquartered in Paris, France, ESA has a worldwide staff of about 2,200 in 2018[7] and an annual budget of about 5.6 billion (~US$7 billion) in 2018.[3]

ESA's space flight programme includes human spaceflight (mainly through participation in the International Space Station program); the launch and operation of unmanned exploration missions to other planets and the Moon; Earth observation, science and telecommunication; designing launch vehicles; and maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana. The main European launch vehicle Ariane 5 is operated through Arianespace with ESA sharing in the costs of launching and further developing this launch vehicle. The agency is also working with NASA to manufacture the Orion Spacecraft service module, that will fly on the Space Launch System.[8][9]

The agency's facilities are distributed among the following centres:

After World War II, many European scientists left Western Europe in order to work with the United States. Although the 1950s boom made it possible for Western European countries to invest in research and specifically in space-related activities, Western European scientists realised solely national projects would not be able to compete with the two main superpowers. In 1958, only months after the Sputnik shock, Edoardo Amaldi (Italy) and Pierre Auger (France), two prominent members of the Western European scientific community, met to discuss the foundation of a common Western European space agency. The meeting was attended by scientific representatives from eight countries, including Harrie Massey (United Kingdom).

The Western European nations decided to have two agencies: one concerned with developing a launch system, ELDO (European Launch Development Organization), and the other the precursor of the European Space Agency, ESRO (European Space Research Organisation). The latter was established on 20 March 1964 by an agreement signed on 14 June 1962. From 1968 to 1972, ESRO launched seven research satellites.

ESA in its current form was founded with the ESA Convention in 1975, when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom.[10] These signed the ESA Convention in 1975 and deposited the instruments of ratification by 1980, when the convention came into force. During this interval the agency functioned in a de facto fashion. ESA launched its first major scientific mission in 1975, Cos-B, a space probe monitoring gamma-ray emissions in the universe, which was first worked on by ESRO.

The ESA collaborated with NASA on the International Ultraviolet Explorer (IUE), the world's first high-orbit telescope, which was launched in 1978 and operated successfully for 18 years. A number of successful Earth-orbit projects followed, and in 1986 ESA began Giotto, its first deep-space mission, to study the comets Halley and GriggSkjellerup. Hipparcos, a star-mapping mission, was launched in 1989 and in the 1990s SOHO, Ulysses and the Hubble Space Telescope were all jointly carried out with NASA. Later scientific missions in cooperation with NASA include the CassiniHuygens space probe, to which ESA contributed by building the Titan landing module Huygens.

As the successor of ELDO, ESA has also constructed rockets for scientific and commercial payloads. Ariane 1, launched in 1979, carried mostly commercial payloads into orbit from 1984 onward. The next two versions of the Ariane rocket were intermediate stages in the development of a more advanced launch system, the Ariane 4, which operated between 1988 and 2003 and established ESA as the world leader[citation needed] in commercial space launches in the 1990s. Although the succeeding Ariane 5 experienced a failure on its first flight, it has since firmly established itself within the heavily competitive commercial space launch market with 82 successful launches until 2018. The successor launch vehicle of Ariane 5, the Ariane 6, is under development and is envisioned to enter service in the 2020s.

The beginning of the new millennium saw ESA become, along with agencies like NASA, JAXA, ISRO, CSA and Roscosmos, one of the major participants in scientific space research. Although ESA had relied on co-operation with NASA in previous decades, especially the 1990s, changed circumstances (such as tough legal restrictions on information sharing by the United States military) led to decisions to rely more on itself and on co-operation with Russia. A 2011 press issue thus stated:[11]

Russia is ESA's first partner in its efforts to ensure long-term access to space. There is a framework agreement between ESA and the government of the Russian Federation on cooperation and partnership in the exploration and use of outer space for peaceful purposes, and cooperation is already underway in two different areas of launcher activity that will bring benefits to both partners.

Notable outcomes are ESA's include SMART-1, a probe testing cutting-edge new space propulsion technology, the Mars Express and Venus Express missions, as well as the development of the Ariane 5 rocket and its role in the ISS partnership. ESA maintains its scientific and research projects mainly for astronomy-space missions such as Corot, launched on 27 December 2006, a milestone in the search for exoplanets.

The treaty establishing the European Space Agency reads:[12]

ESA's purpose shall be to provide for, and to promote, for exclusively peaceful purposes, cooperation among the European States in space research and technology and their space applications, with a view to their being used for scientific purposes and for operational space applications systems

ESA is responsible for setting a unified space and related industrial policy, recommending space objectives to the member states, and integrating national programs like satellite development, into the European program as much as possible.[12]

Jean-Jacques Dordain ESA's Director General (2003-2015) outlined the European Space Agency's mission in a 2003 interview:[13]

Today space activities have pursued the benefit of citizens, and citizens are asking for a better quality of life on Earth. They want greater security and economic wealth, but they also want to pursue their dreams, to increase their knowledge, and they want younger people to be attracted to the pursuit of science and technology.

I think that space can do all of this: it can produce a higher quality of life, better security, more economic wealth, and also fulfill our citizens' dreams and thirst for knowledge, and attract the young generation. This is the reason space exploration is an integral part of overall space activities. It has always been so, and it will be even more important in the future.

ESA describes its work in two overlapping ways:

According to the ESA website, the activities are:

Every member country must contribute to these programmes, listed according to:[14]

Depending on their individual choices the countries can contribute to the following programmes, listed according to:[15]

ESA member states

ESA associate members

ECS states

Signatories of the Cooperation Agreement

By 2015, ESA was an intergovernmental organisation of 22 member states.[6] Member states participate to varying degrees in the mandatory (25% of total expenditures in 2008) and optional space programmes (75% of total expenditures in 2008).[16] The 2008 budget amounted to 3.0 billion the 2009 budget to 3.6 billion.[17] The total budget amounted to about 3.7 billion in 2010, 3.99 billion in 2011, 4.02 billion in 2012, 4.28 billion in 2013, 4.10 billion in 2014 and 4.33 billion in 2015.[18][19][20][21][22] Languages generally used are English and French. Additionally, official documents are also provided in German and documents regarding the Spacelab are also provided in Italian. If found appropriate, the agency may conduct its correspondence in any language of a member state.

The following table lists all the member states and adjunct members, their ESA convention ratification dates, and their contributions in 2018:[3]

Currently the only associated member state is Slovenia.[34] Previously associated members were Austria, Norway and Finland, all of which later joined ESA as full members.

Since 1 January 1979, Canada has had the special status of a Cooperating State within ESA. By virtue of this accord, the Canadian Space Agency takes part in ESA's deliberative bodies and decision-making and also in ESA's programmes and activities. Canadian firms can bid for and receive contracts to work on programmes. The accord has a provision ensuring a fair industrial return to Canada.[36] The most recent Cooperation Agreement was signed on 2010-12-15 with a term extending to 2020.[37][38] For 2014, Canada's annual assessed contribution to the ESA general budget was 6,059,449 (CAD$8,559,050).[39] For 2017, Canada has increased its annual contribution to 21,600,000 (CAD$30,000,000).[40]

ESA is funded from annual contributions by national governments as well as from an annual contribution by the European Union (EU).[41]

The budget of ESA was 5.250 billion in 2016.[42] Every 34 years, ESA member states agree on a budget plan for several years at an ESA member states conference. This plan can be amended in future years, however provides the major guideline for ESA for several years.[citation needed] The 2016 budget allocations for major areas of ESA activity are shown in the chart on the right.[42]

Countries typically have their own space programmes that differ in how they operate organisationally and financially with ESA. For example, the French space agency CNES has a total budget of 2015 million, of which 755 million is paid as direct financial contribution to ESA.[43] Several space-related projects are joint projects between national space agencies and ESA (e.g. COROT). Also, ESA is not the only European governmental space organisation (for example European Union Satellite Centre).

After the decision of the ESA Council of 21/22 March 2001, the procedure for accession of the European states was detailed as described the document titled "The Plan for European Co-operating States (PECS)".[44]Nations that want to become a full member of ESA do so in 3 stages. First a Cooperation Agreement is signed between the country and ESA. In this stage, the country has very limited financial responsibilities. If a country wants to co-operate more fully with ESA, it signs a European Cooperating State (ECS) Agreement. The ECS Agreement makes companies based in the country eligible for participation in ESA procurements. The country can also participate in all ESA programmes, except for the Basic Technology Research Programme. While the financial contribution of the country concerned increases, it is still much lower than that of a full member state. The agreement is normally followed by a Plan For European Cooperating State (or PECS Charter). This is a 5-year programme of basic research and development activities aimed at improving the nation's space industry capacity. At the end of the 5-year period, the country can either begin negotiations to become a full member state or an associated state or sign a new PECS Charter.[45] Many countries, most of which joined the EU in both 2004 and 2007, have started to co-operate with ESA on various levels:

During the Ministerial Meeting in December 2014, ESA ministers approved a resolution calling for discussions to begin with Israel, Australia and South Africa on future association agreements. The ministers noted that concrete cooperation is at an advanced stage with these nations and that prospects for mutual benefits are existing.[68]

A separate space exploration strategy resolution calls for further co-operation with the United States, Russia and China on "LEO exploration, including a continuation of ISS cooperation and the development of a robust plan for the coordinated use of space transportation vehicles and systems for exploration purposes, participation in robotic missions for the exploration of the Moon, the robotic exploration of Mars, leading to a broad Mars Sample Return mission in which Europe should be involved as a full partner, and human missions beyond LEO in the longer term."[68]

The political perspective of the European Union (EU) was to make ESA an agency of the EU by 2014,[69] although this date was not met. The EU is already the largest single donor to ESA's budget and non-ESA EU states are observers at ESA.

ESA has a fleet of different launch vehicles in service with which it competes in all sectors of the launch market. ESA's fleet consists of three major rocket designs: Ariane 5, Soyuz-2 and Vega. Rocket launches are carried out by Arianespace, which has 23 shareholders representing the industry that manufactures the Ariane 5 as well as CNES, at ESA's Guiana Space Centre. Because many communication satellites have equatorial orbits, launches from French Guiana are able to take larger payloads into space than from spaceports at higher latitudes. In addition, equatorial launches give spacecraft an extra 'push' of nearly 500m/s due to the higher rotational velocity of the Earth at the equator compared to near the Earth's poles where rotational velocity approaches zero.

The Ariane 5 rocket is ESA's primary launcher. It has been in service since 1997 and replaced Ariane 4. Two different variants are currently in use. The heaviest and most used version, the Ariane 5 ECA, delivers two communications satellites of up to 10 tonnes into GTO. It failed during its first test flight in 2002, but has since made 82 consecutive successful flights until a partial failure in January 2018. The other version, Ariane 5 ES, was used to launch the Automated Transfer Vehicle (ATV) to the International Space Station (ISS) and will be used to launch four Galileo navigational satellites at a time.[70][71]

In November 2012, ESA agreed to build an upgraded variant called Ariane 5 ME (Mid-life Evolution) which would increase payload capacity to 11.5 tonnes to GTO and feature a restartable second stage to allow more complex missions. Ariane 5 ME was scheduled to fly in 2018[72], but the whole project was scrapped in favor of Ariane 6, planned to replace Ariane 5 in the 2020s.

ESA's Ariane 1, 2, 3 and 4 launchers (the last of which was ESA's long-time workhorse) have been retired.

Soyuz-2 (also called the Soyuz-ST or Soyuz-STK) is a Russian medium payload launcher (ca. 3 metric tons to GTO) which was brought into ESA service in October 2011.[73][74] ESA entered into a 340 million joint venture with the Russian Federal Space Agency over the use of the Soyuz launcher.[11] Under the agreement, the Russian agency manufactures Soyuz rocket parts for ESA, which are then shipped to French Guiana for assembly.

ESA benefits because it gains a medium payload launcher, complementing its fleet while saving on development costs. In addition, the Soyuz rocketwhich has been the Russian's space launch workhorse for some 40 yearsis proven technology with a very good safety record. Russia benefits in that it gets access to the Kourou launch site. Due to its proximity to the equator, launching from Kourou rather than Baikonur nearly doubles Soyuz's payload to GTO (3.0 tonnes vs. 1.7 tonnes).

Soyuz first launched from Kourou on 21 October 2011, and successfully placed two Galileo satellites into orbit 23,222 kilometres above Earth.[73]

Vega is ESA's carrier for small satellites. Developed by seven ESA members led by Italy, it is capable of carrying a payload with a mass of between 300 and 1500kg to an altitude of 700km, for low polar orbit. Its maiden launch from Kourou was on 13 February 2012.[75] Vega began full commercial exploitation in December 2015 [76]

The rocket has three solid propulsion stages and a liquid propulsion upper stage (the AVUM) for accurate orbital insertion and the ability to place multiple payloads into different orbits.[77][78]

Historically, the Ariane family rockets have been funded primarily "with money contributed by ESA governments seeking to participate in the program rather than through competitive industry bids. This [has meant that] governments commit multiyear funding to the development with the expectation of a roughly 90% return on investment in the form of industrial workshare." ESA is proposing changes to this scheme by moving to competitive bids for the development of the Ariane 6.[79]

At the time ESA was formed, its main goals did not encompass human space flight; rather it considered itself to be primarily a scientific research organisation for unmanned space exploration in contrast to its American and Soviet counterparts. It is therefore not surprising that the first non-Soviet European in space was not an ESA astronaut on a European space craft; it was Czechoslovak Vladimr Remek who in 1978 became the first non-Soviet or American in space (the first man in space being Yuri Gagarin of the Soviet Union) on a Soviet Soyuz spacecraft, followed by the Pole Mirosaw Hermaszewski and East German Sigmund Jhn in the same year. This Soviet co-operation programme, known as Intercosmos, primarily involved the participation of Eastern bloc countries. In 1982, however, Jean-Loup Chrtien became the first non-Communist Bloc astronaut on a flight to the Soviet Salyut 7 space station.

Because Chrtien did not officially fly into space as an ESA astronaut, but rather as a member of the French CNES astronaut corps, the German Ulf Merbold is considered the first ESA astronaut to fly into space. He participated in the STS-9 Space Shuttle mission that included the first use of the European-built Spacelab in 1983. STS-9 marked the beginning of an extensive ESA/NASA joint partnership that included dozens of space flights of ESA astronauts in the following years. Some of these missions with Spacelab were fully funded and organizationally and scientifically controlled by ESA (such as two missions by Germany and one by Japan) with European astronauts as full crew members rather than guests on board. Beside paying for Spacelab flights and seats on the shuttles, ESA continued its human space flight co-operation with the Soviet Union and later Russia, including numerous visits to Mir.

During the latter half of the 1980s, European human space flights changed from being the exception to routine and therefore, in 1990, the European Astronaut Centre in Cologne, Germany was established. It selects and trains prospective astronauts and is responsible for the co-ordination with international partners, especially with regard to the International Space Station. As of 2006, the ESA astronaut corps officially included twelve members, including nationals from most large European countries except the United Kingdom.

In the summer of 2008, ESA started to recruit new astronauts so that final selection would be due in spring 2009. Almost 10,000 people registered as astronaut candidates before registration ended in June 2008. 8,413 fulfilled the initial application criteria. Of the applicants, 918 were chosen to take part in the first stage of psychological testing, which narrowed down the field to 192. After two-stage psychological tests and medical evaluation in early 2009, as well as formal interviews, six new members of the European Astronaut Corps were selected - five men and one woman.[80]

The astronauts of the European Space Agency are:

In the 1980s, France pressed for an independent European crew launch vehicle. Around 1978 it was decided to pursue a reusable spacecraft model and starting in November 1987 a project to create a mini-shuttle by the name of Hermes was introduced. The craft was comparable to early proposals for the Space Shuttle and consisted of a small reusable spaceship that would carry 3 to 5 astronauts and 3 to 4 metric tons of payload for scientific experiments. With a total maximum weight of 21 metric tons it would have been launched on the Ariane 5 rocket, which was being developed at that time. It was planned solely for use in low Earth orbit space flights. The planning and pre-development phase concluded in 1991; the production phase was never fully implemented because at that time the political landscape had changed significantly. With the fall of the Soviet Union ESA looked forward to co-operation with Russia to build a next-generation space vehicle. Thus the Hermes programme was cancelled in 1995 after about 3 billion dollars had been spent. The Columbus space station programme had a similar fate.

In the 21st century, ESA started new programmes in order to create its own crew vehicles, most notable among its various projects and proposals is Hopper, whose prototype by EADS, called Phoenix, has already been tested. While projects such as Hopper are neither concrete nor to be realised within the next decade, other possibilities for human spaceflight in co-operation with the Russian Space Agency have emerged. Following talks with the Russian Space Agency in 2004 and June 2005,[85] a co-operation between ESA and the Russian Space Agency was announced to jointly work on the Russian-designed Kliper, a reusable spacecraft that would be available for space travel beyond LEO (e.g. the moon or even Mars). It was speculated that Europe would finance part of it. A 50 million participation study for Kliper, which was expected to be approved in December 2005, was finally not approved by the ESA member states. The Russian state tender for the project was subsequently cancelled in 2006.

In June 2006, ESA member states granted 15 million to the Crew Space Transportation System (CSTS) study, a two-year study to design a spacecraft capable of going beyond Low-Earth orbit based on the current Soyuz design. This project was pursued with Roskosmos instead of the cancelled Kliper proposal. A decision on the actual implementation and construction of the CSTS spacecraft was contemplated for 2008.In mid-2009 EADS Astrium was awarded a 21 million study into designing a crew vehicle based on the European ATV which is believed to now be the basis of the Advanced Crew Transportation System design.[86]

In November 2012, ESA decided to join NASA's Orion programme. The ATV would form the basis of a propulsion unit for NASA's new manned spacecraft. ESA may also seek to work with NASA on Orion's launch system as well in order to secure a seat on the spacecraft for its own astronauts.[87]

In September 2014, ESA signed an agreement with Sierra Nevada Corporation for co-operation in Dream Chaser project. Further studies on the Dream Chaser for European Utilization or DC4EU project were funded, including the feasibility of launching a Europeanized Dream Chaser onboard Ariane 5.[88][89]

ESA has signed co-operation agreements with the following states that currently neither plan to integrate as tightly with ESA institutions as Canada, nor envision future membership of ESA: Argentina,[90] Brazil,[91] China,[92] India[93] (for the Chandrayan mission), Russia[94] and Turkey.[95]

Additionally, ESA has joint projects with the European Union, NASA of the United States and is participating in the International Space Station together with the United States (NASA), Russia and Japan (JAXA).

ESA and EU member states

ESA-only members

EU-only members

ESA is not an agency or body of the European Union (EU), and has non-EU countries (Norway, and Switzerland) as members. There are however ties between the two, with various agreements in place and being worked on, to define the legal status of ESA with regard to the EU.[96]

There are common goals between ESA and the EU. ESA has an EU liaison office in Brussels. On certain projects, the EU and ESA co-operate, such as the upcoming Galileo satellite navigation system. Space policy has since December 2009 been an area for voting in the European Council. Under the European Space Policy of 2007, the EU, ESA and its Member States committed themselves to increasing co-ordination of their activities and programmes and to organising their respective roles relating to space.[97]

The Lisbon Treaty of 2009 reinforces the case for space in Europe and strengthens the role of ESA as an R&D space agency. Article 189 of the Treaty gives the EU a mandate to elaborate a European space policy and take related measures, and provides that the EU should establish appropriate relations with ESA.

Former Italian astronaut Umberto Guidoni, during his tenure as a Member of the European Parliament from 2004 to 2009, stressed the importance of the European Union as a driving force for space exploration, "since other players are coming up such as India and China it is becoming ever more important that Europeans can have an independent access to space. We have to invest more into space research and technology in order to have an industry capable of competing with other international players."[98]

The first EU-ESA International Conference on Human Space Exploration took place in Prague on 22 and 23 October 2009.[99] A road map which would lead to a common vision and strategic planning in the area of space exploration was discussed. Ministers from all 29 EU and ESA members as well as members of parliament were in attendance.[100]

ESA has a long history of collaboration with NASA. Since ESA's astronaut corps was formed, the Space Shuttle has been the primary launch vehicle used by ESA's astronauts to get into space through partnership programmes with NASA. In the 1980s and 1990s, the Spacelab programme was an ESA-NASA joint research programme that had ESA develop and manufacture orbital labs for the Space Shuttle for several flights on which ESA participate with astronauts in experiments.

In robotic science mission and exploration missions, NASA has been ESA's main partner. CassiniHuygens was a joint NASA-ESA mission, along with the Infrared Space Observatory, INTEGRAL, SOHO, and others. Also, the Hubble space telescope is a joint project of NASA and ESA. Future ESA-NASA joint projects include the James Webb Space Telescope and the proposed Laser Interferometer Space Antenna.[citation needed] NASA has committed to provide support to ESA's proposed MarcoPolo-R mission to return an asteroid sample to Earth for further analysis.[citation needed] NASA and ESA will also likely join together for a Mars Sample Return Mission.[101]

Since China has started to invest more money into space activities, the Chinese Space Agency has sought international partnerships. ESA is, beside the Russian Space Agency, one of its most important partners. Two space agencies cooperated in the development of the Double Star Mission.[102] In 2017, ESA sent two astronauts to China for two weeks sea survival training with Chinese astronauts in Yantai, Shandong.[103]

ESA entered into a major joint venture with Russia in the form of the CSTS, the preparation of French Guiana spaceport for launches of Soyuz-2 rockets and other projects. With India, ESA agreed to send instruments into space aboard the ISRO's Chandrayaan-1 in 2008.[104] ESA is also co-operating with Japan, the most notable current project in collaboration with JAXA is the BepiColombo mission to Mercury.

Speaking to reporters at an air show near Moscow in August 2011, ESA head Jean-Jacques Dordain said ESA and Russia's Roskosmos space agency would "carry out the first flight to Mars together."[105]

With regard to the International Space Station (ISS) ESA is not represented by all of its member states:[106] 10 of the 21 ESA member states currently participate in the project: Belgium, Denmark, France, Germany, Italy, Netherlands, Norway, Spain, Sweden and Switzerland. Austria, Finland and Ireland chose not to participate, because of lack of interest or concerns about the expense of the project. The United Kingdom withdrew from the preliminary agreement because of concerns about the expense of the project. Portugal, Luxembourg, Greece, the Czech Republic, Romania and Poland joined ESA after the agreement had been signed. ESA is taking part in the construction and operation of the ISS with contributions such as Columbus, a science laboratory module that was brought into orbit by NASA's STS-122 Space Shuttle mission and the Cupola observatory module that was completed in July 2005 by Alenia Spazio for ESA. The current estimates for the ISS are approaching 100 billion in total (development, construction and 10 years of maintaining the station) of which ESA has committed to paying 8 billion.[107] About 90% of the costs of ESA's ISS share will be contributed by Germany (41%), France (28%) and Italy (20%). German ESA astronaut Thomas Reiter was the first long-term ISS crew member.

ESA has developed the Automated Transfer Vehicle for ISS resupply. Each ATV has a cargo capacity of 7,667 kilograms (16,903lb).[108] The first ATV, Jules Verne, was launched on 9 March 2008 and on 3 April 2008 successfully docked with the ISS. This manoeuvre, considered a major technical feat, involved using automated systems to allow the ATV to track the ISS, moving at 27,000km/h, and attach itself with an accuracy of 2cm.

As of 2013, the spacecraft establishing supply links to the ISS are the Russian Progress and Soyuz, European ATV, Japanese Kounotori (HTV), and the USA COTS program vehicles Dragon and Cygnus.

European Life and Physical Sciences research on board the International Space Station (ISS) is mainly based on the European Programme for Life and Physical Sciences in Space programme that was initiated in 2001.

According to Annex 1, Resolution No. 8 of the ESA Convention and Council Rules of Procedure,[4] English, French and German may be used in all meetings of the Agency, with interpretation provided into these three languages. All official documents are available in English and French with all documents concerning the ESA Council being available in German as well.

The Flag of Europe is the one to be flown in space during missions (for example it was flown by ESA's Andre Kuipers during Delta mission)

The Commission is increasingly working together towards common objectives. Some 20 per cent of the funds managed by ESA now originate from the supranational budget of the European Union.

However, in recent years the ties between ESA and the European institutions have been reinforced by the increasing role that space plays in supporting Europes social, political and economic policies.

The legal basis for the EU/ESA co-operation is provided by a Framework Agreement which entered into force in May 2004. According to this agreement, the European Commission and ESA co-ordinate their actions through the Joint Secretariat, a small team of ECs administrators and ESA executive. The Member States of the two organisations meet at ministerial level in the Space Council, which is a concomitant meeting of the EU and ESA Councils, prepared by Member States representatives in the High-level Space Policy Group (HSPG).

ESA maintains a liaison office in Brussels to facilitate relations with the European institutions.

In May 2007, the 29 European countries expressed their support for the European Space Policy in a resolution of the Space Council, unifying the approach of ESA with those of the European Union and their member states.

Prepared jointly by the European Commission and ESAs Director General, the European Space Policy sets out a basic vision and strategy for the space sector and addresses issues such as security and defence, access to space and exploration.

Through this resolution, the EU, ESA and their Member States all commit to increasing co-ordination of their activities and programmes and their respective roles relating to space.[111]

On 3 August 1984, the ESA's Paris headquarters were severely damaged and six people were hurt when a bomb exploded, planted by the far-left armed Action Directe group.[112]

On 14 December 2015, hackers from Anonymous breached the ESA's subdomains and leaked thousands of login credentials.[113]

Science in space

In the decades following the first Sputnik and Explorer satellites, the ability to put their instruments into outer space gave scientists the opportunity to acquire new information about the natural universe, information that in many cases would have been unobtainable any other way. Space science added a new dimension to the quest for knowledge, complementing and extending what had been gained from centuries of theoretical speculations and ground-based observations.

After Gagarins 1961 flight, space missions involving human crews carried out a range of significant research, from on-site geologic investigations on the Moon to a wide variety of observations and experiments aboard orbiting spacecraft. In particular, the presence in space of humans as experimenters and, in some cases, as experimental subjects facilitated studies in biomedicine and materials science. Nevertheless, most space science was, and continues to be, performed by robotic spacecraft in Earth orbit, in other locations from which they observe the universe, or on missions to various bodies in the solar system. In general, such missions are far less expensive than those involving humans and can carry sophisticated automated instruments to gather a wide variety of relevant data.

In addition to the United States and the Soviet Union, several other countries achieved the capability of developing and operating scientific spacecraft and thus carrying out their own space science missions. They include Japan, China, Canada, India, and a number of European countries such as the United Kingdom, France, Italy, and Germany, acting alone and through cooperative organizations, particularly the European Space Agency. Furthermore, many other countries became involved in space activities through the participation of their scientists in specific missions. Bilateral or multilateral cooperation between various countries in carrying out space science missions grew to be the usual way of proceeding.

Scientific research in space can be divided into five general areas: (1) solar and space physics, including study of the magnetic and electromagnetic fields in space and the various energetic particles also present, with particular attention to their interactions with Earth, (2) exploration of the planets, moons, asteroids, comets, meteoroids, and dust in the solar system, (3) study of the origin, evolution, and current state of the varied objects in the universe beyond the solar system, (4) research on nonliving and living materials, including humans, in the very low gravity levels of the space environment, and (5) study of Earth from space.

The first scientific discovery made with instruments orbiting in space was the existence of the Van Allen radiation belts, discovered by Explorer 1 in 1958. Subsequent space missions investigated Earths magnetosphere, the surrounding region of space in which the planets magnetic field exerts a controlling effect (see Earth: The magnetic field and magnetosphere). Of particular and ongoing interest has been the interaction of the flux of charged particles emitted by the Sun, called the solar wind, with the magnetosphere. Early space science investigations showed, for example, that luminous atmospheric displays known as auroras are the result of this interaction, and scientists came to understand that the magnetosphere is an extremely complex phenomenon.

The focus of inquiry in space physics was later extended to understanding the characteristics of the Sun, both as an average star and as the primary source of energy for the rest of the solar system, and to exploring space between the Sun and Earth and other planets (see interplanetary medium). The magnetospheres of other planets, particularly Jupiter with its strong magnetic field, also came under study. Scientists sought a better understanding of the internal dynamics and overall behaviour of the Sun, the underlying causes of variations in solar activity, and the way in which those variations propagate through space and ultimately affect Earths magnetosphere and upper atmosphere. The concept of space weather was advanced to describe the changing conditions in the Sun-Earth region of the solar system. Variations in space weather can cause geomagnetic storms that interfere with the operation of satellites and even systems on the ground such as power grids.

To carry out the investigations required for addressing these scientific questions, the United States, Europe, the Soviet Union, and Japan developed a variety of space missions, often in a coordinated fashion. In the United States, early studies of the Sun were undertaken by a series of Orbiting Solar Observatory satellites (launched 196275) and the astronaut crews of the Skylab space station in 197374, using that facilitys Apollo Telescope Mount. These were followed by the Solar Maximum Mission satellite (launched 1980). ESA developed the Ulysses mission (1990) to explore the Suns polar regions. Solar-terrestrial interactions were the focus of many of the Explorer series of spacecraft (195875) and the Orbiting Geophysical Observatory satellites (196469). In the 1980s NASA, ESA, and Japans Institute of Space and Astronautical Science undertook a cooperative venture to develop a comprehensive series of space missions, named the International Solar-Terrestrial Physics Program, that would be aimed at full investigation of the Sun-Earth connection. This program was responsible for the U.S. Wind (1994) and Polar (1996) spacecraft, the European Solar and Heliospheric Observatory (SOHO; 1995) and Cluster (2000) missions, and the Japanese Geotail satellite (1992). Among many other missions, NASA has launched a number of satellites, including Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED, 2001); the Japanese-U.S.-U.K. collaboration Hinode (2006); and Solar Terrestrial Relations Observatory (STEREO, 2006), part of its Solar Terrestrial Probes program. The Solar Dynamics Observatory (2010) and the twin Van Allen Probes (2012) were part of another NASA program called Living with a Star. A two-satellite European/Chinese mission called Double Star (200304) studied the impact of the Sun on Earths environment.

From the start of space activity, scientists recognized that spacecraft could gather scientifically valuable data about the various planets, moons, and smaller bodies in the solar system. Both the United States and the U.S.S.R. attempted to send robotic missions to the Moon in the late 1950s. The first four U.S. Pioneer spacecraft, Pioneer 03, launched in 1958, were not successful in returning data about the Moon. The fifth mission, Pioneer 4 (1959), was the first U.S. spacecraft to escape Earths gravitational pull; it flew by the Moon at twice the planned distance but returned some useful data. Three Soviet missions, Luna 13, explored the vicinity of the Moon in 1959, confirming that it had no appreciable magnetic field and sending back the first-ever images of its far side. Luna 1 was the first spacecraft to fly past the Moon, beating Pioneer 4 by two months. Luna 2, in making a hard landing on the lunar surface, was the first spacecraft to strike another celestial object. Later, in the 1960s and early 1970s, Luna and Lunokhod spacecraft soft-landed on the Moon, and some gathered soil samples and returned them to Earth.

In the 1960s the United States became the first country to send a spacecraft to the vicinity of other planets; Mariner 2 flew by Venus in December 1962, and Mariner 4 flew past Mars in July 1965. Among significant accomplishments of planetary missions in succeeding decades were the U.S. Viking landings on Mars in 1976 and the Soviet Venera explorations of the atmosphere and surface of Venus from the mid-1960s to the mid-1980s. In the years since, the United States has continued an active program of solar system exploration, as did the Soviet Union until its dissolution in 1991. Japan launched missions to the Moon, Mars, and Halleys Comet and returned minute samples from the asteroid Itokawa. Europes first independent solar system mission, Giotto, also flew by Halley. After the turn of the 21st century, it sent missions to the Moon and Mars and an orbiter-lander, Rosetta-Philae, to a comet. India and China also sent the Chandrayaan-1 (2008) and two Change (2007, 2010) missions, respectively, to orbit the Moon. Chinas Change 3 mission also landed a small rover, Yutu, on the Moon in 2013. NASAs Dawn mission (2007) orbited the large asteroid Vesta from 2011 to 2012 and entered orbit around the dwarf planet Ceres in 2015.

Early on, scientists planned to conduct solar system exploration in three stages: initial reconnaissance from spacecraft flying by a planet, comet, or asteroid; detailed surveillance from a spacecraft orbiting the object; and on-site research after landing on the object or, in the case of a giant gas planet, by sending a probe into its atmosphere. By the early 21st century, all three of those stages had been carried out for the Moon, Venus, Mars, Jupiter, Saturn, and a near-Earth asteroid. Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars. A long-term, detailed surveillance of Jupiter and its moons began in 1995 when the U.S. Galileo spacecraft took up orbit around the planet, at the same time releasing a probe into the turbulent Jovian atmosphere. In 2001 the U.S. Near Earth Asteroid Rendezvous (NEAR) spacecraft landed on the asteroid Eros and transmitted information from its surface for more than two weeks. Among the rocky inner planets, only Mercury was for some time relatively neglected. In the first half century of space exploration, Mercury was visited just once; the U.S. Mariner 10 probe made three flybys of the planet in 197475. In 2004 the U.S. Messenger spacecraft was launched to Mercury for a series of flybys beginning in 2008 and entered orbit around the planet in 2011.

As of 2017, the exploration of the two outer giant gas planetsUranus and Neptuneremained at the first stage. In a series of U.S. missions launched in the 1970s, Pioneer 10 flew by Jupiter, whereas Pioneer 11 and Voyager 1 and 2 flew by both Jupiter and Saturn. Voyager 2 then went on to travel past Uranus and Neptune. On August 25, 2012, Voyager 1 became the first space probe to enter interstellar space when it crossed the heliopause, the outer limit of the Suns magnetic field and solar wind. The Voyagers were expected to still be returning data through 2020. The U.S. Cassini spacecraft, launched in 1997, began a long-term surveillance mission in the Saturnian system in 2004; the following year its European-built Huygens probe descended to the surface of Titan, Saturns largest moon. In 2017 the Cassini mission ended when it burned up in Saturns atmosphere. In 2011 the United States launched the Juno mission, which studied the origin and evolution of Jupiter after it arrived at the giant planet in 2016. Thus, every significant body in the solar system, even the dwarf planet Pluto and its largest moon, Charon, has been visited at least once by a spacecraft. (The U.S. New Horizons spacecraft, launched in 2006, flew by Pluto and Charon in 2015.)

These exploratory missions sought information on the origin and evolution of the solar system and on the various objects that it comprises, including chemical composition; surface topography; data on magnetic fields, atmospheres, and volcanic activity; and, particularly for Mars, evidence of water in the present or past and perhaps even of extraterrestrial life in some form.

What has been learned to date confirms that Earth and the rest of the solar system formed at about the same time from the same cloud of gas and dust surrounding the Sun. The four outer giant gas planets are roughly similar in size and chemical composition, but each has a set of moons that differ widely in their characteristics, and in some ways they and their satellites resemble miniature solar systems. The four rocky inner planets had a common origin but followed very different evolutionary paths and today have very different surfaces, atmospheres, and internal activity. Ongoing comparative study of the evolution of Venus, Mars, and Earth could provide important insights into Earths future and its continued ability to support life.

The question of whether life has ever existed elsewhere in the solar system continues to intrigue both scientists and the general public. The United States sent two Viking spacecraft to land on the surface of Mars in 1976. Each contained three experiments intended to search for traces of organic material that might indicate the presence of past or present life-forms; none of the experiments produced positive results. Twenty years later, a team of scientists studying a meteorite of Martian origin found in Antarctica announced the discovery of possible microscopic fossils resulting from past organic life. Their claim was not universally accepted, but it led to an accelerated program of Martian exploration focused on the search for evidence of the action of liquid water, thought necessary for life to have evolved. Beginning in 2001, the United States sent a series of follow the water missions to orbit or land on Mars, including 2001 Mars Odyssey (2001), two Mars Exploration Rovers, Spirit and Opportunity (2003), Mars Reconnaissance Orbiter (2005), and the Curiosity rover (2011). Europe also launched the Mars Express mission in 2003. A major long-term goal of the Mars exploration program is to return samples of the Martian surface to Earth for laboratory analysis.

There are indications that water may be present in the outer solar system. The Galileo mission provided images and other data related to Jupiters moon Europa that suggest the presence of a liquid water ocean beneath its icy crust. Future missions are needed to confirm the existence of this ocean and search for evidence of organic or biological processes in it. The Cassini-Huygens mission confirmed the presence of lakes of liquid methane on Saturns moon Titan and suggested the likely existence of liquid water underneath the surface of another moon, Enceladus.

Space Exploration | Encyclopedia.com

space exploration, the investigation of physical conditions in space and on stars, planets, and other celestial bodies through the use of artificial satellites (spacecraft that orbit the earth), space probes (spacecraft that pass through the solar system and that may or may not orbit another celestial body), and spacecraft with human crews.

Satellites and Probes

Although studies from earth using optical and radio telescopes had accumulated much data on the nature of celestial bodies, it was not until after World War II that the development of powerful rockets made direct space exploration a technological possibility. The first artificial satellite, Sputnik I, was launched by the USSR (now Russia) on Oct. 4, 1957, and spurred the dormant U.S. program into action, leading to an international competition popularly known as the"space race."Explorer I, the first American satellite, was launched on Jan. 31, 1958. Although earth-orbiting satellites have by far accounted for the great majority of launches in the space program, even more information on the moon, other planets, and the sun has been acquired by space probes.

Lunar Probes

In the decade following Sputnik I, the United States and the USSR between them launched about 50 space probes to explore the moon. The first probes were intended either to pass very close to the moon (flyby) or to crash into it (hard landing). Later probes made soft landings with instruments intact and achieved stable orbits around the moon. Each of these four objectives required increasingly greater rocket power and more precise maneuvering; successive launches in the Soviet Luna series were the first to accomplish each objective. Luna 2 made a hard lunar landing in Sept., 1959, and Luna 3 took pictures of the moon's far side as the probe flew by in Nov., 1959. Luna 9 soft-landed in Feb., 1966, and Luna 10 orbited the moon in Apr., 1966; both sent back many television pictures to earth. Beginning with Luna 16, which was launched in Sept., 1970, the USSR sent a several probes to the moon that either returned lunar soil samples to earth or deployed Lunokhod rovers. In addition to the 24 lunar probes in the Luna program, the Soviets also launched five circumlunar probes in its Zond program.

Early American successes generally lagged behind Soviet accomplishments by several months but provided more detailed scientific information. The U.S. program did not bear fruit until 1964, when Rangers 7,8, and 9 transmitted thousands of pictures, many taken at altitudes of less than 1 mi (1.6 km) just before impact and showing craters only a few feet in diameter. Two years later, the Surveyor series began a program of soft landings on the moon. Surveyor 1 touched down in June, 1966; in addition to television cameras, it carried instruments to measure soil strength and composition. The Surveyor program established that the moon's surface was solid enough to support a spacecraft carrying astronauts.

In Aug., 1966, the United States successfully launched the first Lunar Orbiter, which took pictures of both sides of the moon as well as the first pictures of the earth from the moon's vicinity. The Orbiter's primary mission was to locate suitable landing sites for the Apollo Lunar Module, but in the process it also discovered the lunar mascons, regions of large concentration of mass on the moon's surface. Between May, 1966, and Nov., 1968, the United States launched seven Surveyors and five Lunar Orbiters. Clementine, launched in 1994, engaged in a systematic mapping of the lunar surface. In 1998, Lunar Prospector orbited the moon in a low polar orbit investigating possible polar ice deposits, but a controlled crash near the south pole detected no water. The U.S. Lunar Reconnaissance Orbiter, launched in 2009, was designed to collect data that can be used to prepare for future missions to the moon; information from it has been used to produce a relatively detailed, nearly complete topographic map of the moon.

China became the third nation to send a spacecraft to the moon when Chang'e 1, which was launched in 2007, orbited and mapped the moon until it was crash-landed on the lunar surface in 2009. Chang'e 2 also orbited and mapped the moon (201011) and later conducted a flyby of an asteroid (2012). In Dec., 2013, Chang'e 3 landed on the moon and deployed a rover, Yutu.

Interplanetary Probes

While the bulk of space exploration initially was directed at the earth-moon system, the focus gradually shifted to other members of the solar system. The U.S. Mariner program studied Venus and Mars, the two planets closest to the earth; the Soviet Venera series also studied Venus. From 1962 to 1971, these probes confirmed the high surface temperature and thick atmosphere of Venus, discovered signs of recent volcanism and possible water erosion on Mars, and investigated Mercury. Between 1971 and 1973 the Soviet Union launched six successful probes as part of its Mars program. Exploration of Mars continued with the U.S. Viking landings on the Martian surface. Two Viking spacecraft arrived on Mars in 1976. Their mechanical arms scooped up soil samples for automated tests that searched for photosynthesis, respiration, and metabolism by any microorganisms that might be present; one test suggested at least the possibility of organic activity. The Soviet Phobos 1 and 2 missions were unsuccessful in 1988. The U.S. Magellan spacecraft succeeded in orbiting Venus in 1990, returning a complete radar map of the planet's hidden surface. The Japanese probes Sakigake and Suisei and the European Space Agency's probe Giotto both rendezvoused with Halley's comet in 1986, and Giotto also came within 125 mi (200 km) of the nucleus of the comet Grigg-Skjellerup in 1992. The U.S. probe Ulysses returned data about the poles of the sun in 1994, and the ESA Solar and Heliospheric Observatory (SOHO) was put into orbit in 1995. Launched in 1996 to study asteroids and comets, the Near Earth Asteroid Rendezvous (NEAR) probe made flybys of the asteroids Mathilde (1997) and Eros (1999) and began orbiting the latter in 2000. The Mars Pathfinder and Mars Global Surveyor, both of which reached Mars in 1997, were highly successful, the former in analyzing the Martian surface and the latter in mapping it. The ESA Mars Express, launched in 2003, began orbiting Mars later that year, and although its Beagle 2 lander failed to establish contact, the orbiter has sent back data. Spirit and Opportunity, NASA rovers, landed successfully on Mars in 2004, as did the NASA rover Curiosity in 2012. Messenger, also launched by NASA, became the first space probe to orbit Mercury in 2011; its mission ended in 2015. In 2014 the ESA's Rosetta became the first probe to orbit a comet (Comet 67P); prior to that rendezvous the space probe had made flybys of Mars and two asteroids.

Space probes have also been aimed at the outer planets, with spectacular results. One such probe, Pioneer 10, passed through the asteroid belt in 1973, then became the first object made by human beings to move beyond the orbits of the planets. In 1974, Pioneer 11 photographed Jupiter's equatorial latitudes and its moons, and in 1979 it made the first direct observations of Saturn. Voyagers 1 and 2, which were launched in 1977, took advantage of a rare alignment of Jupiter, Saturn, Uranus, and Neptune to explore all four planets. Passing as close as 3,000 mi (4,800 km) to each planet's surface, the Voyagers discovered new rings, explored complex magnetic fields, and returned detailed photographs of the outer planets and their unique moons. They subsequently moved toward the heliopause, the boundary between the influence of the sun's magnetic field and the interstellar magnetic field, and in 2013 NASA reported that Voyager 1 most likely crossed the heliopause in 2012 and entered interstellar space, becoming the first spacecraft to do so.

Launched in 1989, the Galileo spacecraft followed a circuitous route that enabled it to return data about Venus (1990), the moon (1992), and the asteroids 951 Gaspra (1991) and 243 Ida (1993) before it orbited Jupiter (19952003); it also returned data about the Jupiter's atmosphere and its largest moons (Io, Ganymede, Europa, and Callisto). The joint U.S.-ESA Cassini mission, launched in 1997, began exploring Saturn, its rings, and some of its moons upon arriving in 2004. It deployed Huygens, which landed on the surface of Saturn's moom Titan in early 2005.

Human spaceflight has progressed from the simple to the complex, starting with suborbital flights; subsequent highlights included the launching of a single astronaut in orbit, the launching of several astronauts in a single capsule, the rendezvous and docking of two spacecraft, the attainment of lunar orbit, and the televised landing of an astronaut on the moon. The first person in earth orbit was a Soviet cosmonaut, Yuri Gagarin, in Vostok 1 on Apr. 12, 1961. The American Mercury program had its first orbital success in Feb., 1962, when John Glenn circled the earth three times; a flight of 22 orbits was achieved by Mercury in May, 1963. In Oct., 1964, three Soviet cosmonauts were launched in a Voskhod spacecraft. During the second Voskhod flight in Mar., 1965, a cosmonaut left the capsule to make the first"walk in space."

The first launch of the Gemini program, carrying two American astronauts, occurred a few days after the Soviet spacewalk. The United States made its first spacewalk during Gemini 4, and subsequent flights established techniques for rendezvous and docking in space. The first actual docking of two craft in space was achieved in Mar., 1966, when Gemini 8 docked with a crewless vehicle. In Oct., 1967, two Soviet Cosmos spacecraft performed the first automatic crewless rendezvous and docking. Gemini and Voskhod were followed by the American Apollo and the Soviet Soyuz programs, respectively.

The Apollo Program

In 1961, President Kennedy had committed the United States to the goal of landing astronauts on the moon and bringing them safely back to earth by the end of the decade. The resulting Apollo program was the largest scientific and technological undertaking in history. Apollo 8 was the first craft to orbit both the earth and the moon (Dec., 1968); on July 20, 1969, astronauts Neil A. Armstrong and Edwin E. ("Buzz") Aldrin, Jr., stepped out onto the moon, while a third astronaut, Michael Collins, orbited the moon in the command ship. In all, there were 17 Apollo missions and 6 lunar landings (196972). Apollo 15 marked the first use of the Lunar Rover, a jeeplike vehicle. The scientific mission of Apollo centered around an automated geophysical laboratory, ALSEP (Apollo Lunar Surface Experimental Package). Much was learned about the physical constitution and early history of the moon, including information about magnetic fields, heat flow, volcanism, and seismic activity. The total lunar rock sample returned to earth weighed nearly 900 lb (400 kg).

Apollo moon flights were launched by the three-stage Saturn V rocket, which developed 7.5 million lb (3.4 million kg) of thrust at liftoff. At launch, the total assembly stood 363 ft (110 m) high and weighed more than 3,000 tons. The Apollo spacecraft itself weighed 44 tons and stood nearly 60 ft (20 m) high. It was composed of three sections: the command, service, and lunar modules. In earth orbit, the lunar module (LM) was freed from its protective compartment and docked to the nose of the command module. Once in lunar orbit, two astronauts transferred to the LM, which then detached from the command module and descended to the lunar surface. After lunar exploration, the descent stage of the LM remained on the moon, while the ascent stage was jettisoned after returning the astronauts to the command module. The service module was jettisoned just before reentering the earth's atmosphere. Thus, of the huge craft that left the earth, only the cone-shaped command module returned.

The Soyuz Program

Until late 1969 it appeared that the USSR was also working toward landing cosmonauts on the moon. In Nov., 1968, a Soviet cosmonaut in Soyuz 3 participated in an automated rendezvous and manual approach sequence with the crewless Soyuz 2.Soyuz 4 and 5 docked in space in Jan., 1969, and two cosmonauts transferred from Soyuz 5 to Soyuz 4; it was the first transfer of crew members in space from separately launched vehicles. But in July, 1969, the rocket that was to power the lunar mission exploded, destroying an entire launch complex, and the USSR abandoned the goal of human lunar exploration to concentrate on orbital flights. The program suffered a further setback in June, 1971, when Soyuz 11 accidentally depressurized during reentry, killing all three cosmonauts. In July, 1975, the United States and the USSR carried out the first internationally crewed spaceflight, when an Apollo and a Soyuz spacecraft docked while in earth orbit. Later Soyuz spacecraft have been used to ferry crew members to and from Salyut,Mir, and the International Space Station.

Space Stations

After the geophysical exploration of the moon via the Apollo program was completed, the United States continued human space exploration with Skylab, an earth-orbiting space station that served as workshop and living quarters for three astronauts. The main capsule was launched by a booster; the crews arrived later in an Apollo-type craft that docked to the main capsule. Skylab had an operational lifetime of eight months, during which three three-astronaut crews remained in the space station for periods of about one month, two months, and three months. The first crew reached Skylab in May, 1972.

Skylab's scientific mission alternated between predominantly solar astrophysical research and study of the earth's natural resources; in addition, the crews evaluated their response to prolonged conditions of weightlessness. The solar observatory contained eight high-resolution telescopes, each designed to study a different part of the spectrum (e.g., visible, ultraviolet, X-ray, or infrared light). Particular attention was given to the study of solar flares (see sun). The earth applications, which involved remote sensing of natural resources, relied on visible and infrared light in a technique called multispectral scanning (see space science). The data collected helped scientists to forecast crop and timber yields, locate potentially productive land, detect insect infestation, map deserts, measure snow and ice cover, locate mineral deposits, trace marine and wildlife migrations, and detect the dispersal patterns of air and water pollution. In addition, radar studies yielded information about the surface roughness and electrical properties of the sea on a global basis. Skylab fell out of orbit in July, 1979; despite diligent efforts, several large pieces of debris fell on land.

After that time the only continuing presence of humans in earth orbit were the Soviet Salyut and Mir space stations, in which cosmonauts worked for periods ranging to more than 14 months. In addition to conducting remote sensing and gathering medical data, cosmonauts used their microgravity environment to produce electronic and medical artifacts impossible to create on earth. In preparation for the International Space Station (ISS)a cooperative program of the United States, Russia, Japan, Canada, Brazil, and the ESAastronauts and cosmonauts from Afghanistan, Austria, Britain, Bulgaria, France, Germany, Japan, Kazakhstan, Syria, and the United States worked on Mir alongside their Russian counterparts. Assembly of the ISS began in Dec., 1998, with the linking of an American and a Russian module (see space station) Once the ISS was manned in 2000, maintaining Mir in orbit was no longer necessary and it was made to decay out of orbit in Mar., 2001.

The Space Shuttle

After the Skylab space station fell out of orbit in 1979, the United States did not resume sending astronauts into space until 1981, when the space shuttle, capable of ferrying people and equipment into orbit and back to earth, was launched. The shuttle itself was a hypersonic delta-wing airplane about the size of a DC-9. Takeoff was powered by three liquid-fuel engines fed from an external tank and two solid-fuel engines; the last were recovered by parachute. The shuttle itself returned to earth in a controlled glide, landing either in California or in Florida.

The shuttle put a payload of up to 25 tons (22,700 kg) in earth orbit below 600 mi (970 km); the payload was then boosted into final orbit by its own attached rocket. The Galileo probe, designed to investigate Jupiter's upper atmosphere, was launched from the space shuttle. Astronauts also used the shuttle to retrieve and repair satellites, to experiment with construction techniques needed for a permanent space station, and to conduct scientific experiments during extended periods in space.

At first it was hoped that shuttle flights could operate on a monthly basis, but schedule pressures contributed to the explosion of the Challenger shuttle in 1986, when cold launch conditions led to the failure of a rubber O-ring, and the resulting flame ruptured the main fuel tank. The shuttle program was suspended for three years, while the entire system was redesigned. The shuttle fleet subsequently operated on approximately a bimonthly schedule. A second accident occurred in 2003, when Columbia was lost during reentry because damaged heat shielding on the left wing, which had been damaged by insulation shed from the external fuel tank, failed to prevent superheated gas from entering the wing; the hot gas structurally weakened the wing and caused the shuttle to break up. Shuttle flights resumed in July, 2005, but new problems with fuel tank insulation led NASA to suspend shuttle launches for a year. The last shuttle flight was in July, 2011.

In 2004, President George W. Bush called for a return to the moon by 2020 and the establishment of a base there that would be used to support the human exploration of Mars. The following year NASA unveiled a $104 billion plan for a lunar expedition that resembled that Apollo program in many respects, except that two rockets would be used to launch the crew and lunar lander separately.

In June, 2004, SpaceShipOne, a privately financed spacecraft utilizing a reusable vehicle somewhat similar in concept to the shuttle, was launched into suborbital flight from the Mojave Desert in California. Unlike the shuttle, SpaceShipOne was carried aloft by a reusable jet mothership (White Knight) to 46,000 ft (13.8 km), where it was released and fires its rocket engine. The spacecraft was designed by Bert Rutan and built by his company, SCALED Composites. The vehicle's 90-minute flight was the first successful nongovernmental spaceflight. SpaceShipTwo, based on SpaceShipOne, is being developed for commercial tourist flights; it made its first powered flight in 2013. Another spacecraft was privately developed by Space Exploration Technologies, or SpaceX, in coordination with NASA. The company's Falcon 9 rocket had its first successful launch, from Cape Canaveral, in June, 2010. In Dec., 2010, SpaceX launched the Dragon space capsule, using a Falcon 9 rocket, and successfully returned the capsule to earth after almost two orbits. In May, 2012, the Dragon made its first resupply trip to the space station, returning with experiments and other items. Orbital Sciences Corp. (OSC) also developed a cargo capsule, Cygnus, in cooperation with NASA. OSC's Antares rocket, which is used to launch Cygnus, had its first test in Apr., 2013, and Cygnus had its first resupply flight later that year.

The Chinese Space Program

China launched its first satellite in 1970 and then began the Shuguang program to put an astronaut into space, but the program was twice halted, ending in 1980. In the 1990s, however, China began a new program, and launched the crewless Shenzhou 1, based on the Soyuz, in 1999. The Shenzhou, like the Soyuz, is capable of carrying a crew of three. In Oct., 2003, Shenzhou 5 carried a single astronaut, Yang Liwei, on a 21-hr, 14-orbit flight, making China only the third nation to place a person in orbit. A second mission, involving two astronauts, occurred in Oct., 2005. China also launched an unmanned moon mission in Oct., 2007. In June, 2012, the three-person Shenzhou 9, which included China's first woman astronaut, manually docked with the Tiangong 1 laboratory module.

space exploration | History, Definition, & Facts …

Although the possibility of exploring space has long excited people in many walks of life, for most of the latter 20th century, only national governments could afford the very high costs of launching people and machines into space. This reality meant that space exploration had to serve very broad interests, and it indeed has done so in a variety of ways. Government space programs have increased knowledge, served as indicators of national prestige and power, enhanced national security and military strength, and provided significant benefits to the general public. In areas where the private sector could profit from activities in space, most notably the use of satellites as telecommunication relays, commercial space activity has flourished without government funding. In the early 21st century, entrepreneurs believed that there were several other areas of commercial potential in space, most notably privately funded space travel.

In the years after World War II, governments assumed a leading role in the support of research that increased fundamental knowledge about nature, a role that earlier had been played by universities, private foundations, and other nongovernmental supporters. This change came for two reasons. First, the need for complex equipment to carry out many scientific experiments and for the large teams of researchers to use that equipment led to costs that only governments could afford. Second, governments were willing to take on this responsibility because of the belief that fundamental research would produce new knowledge essential to the health, the security, and the quality of life of their citizens. Thus, when scientists sought government support for early space experiments, it was forthcoming. Since the start of space efforts in the United States, the Soviet Union, and Europe, national governments have given high priority to the support of science done in and from space. From modest beginnings, space science has expanded under government support to include multibillion-dollar exploratory missions in the solar system. Examples of such efforts include the development of the Curiosity Mars rover, the Cassini-Huygens mission to Saturn and its moons, and the development of major space-based astronomical observatories such as the Hubble Space Telescope.

Soviet leader Nikita Khrushchev in 1957 used the fact that his country had been first to launch a satellite as evidence of the technological power of the Soviet Union and of the superiority of communism. He repeated these claims after Yury Gagarins orbital flight in 1961. Although U.S. Pres. Dwight D. Eisenhower had decided not to compete for prestige with the Soviet Union in a space race, his successor, John F. Kennedy, had a different view. On April 20, 1961, in the aftermath of the Gagarin flight, he asked his advisers to identify a space program which promises dramatic results in which we could win. The response came in a May 8, 1961, memorandum recommending that the United States commit to sending people to the Moon, because dramatic achievements in spacesymbolize the technological power and organizing capacity of a nation and because the ensuing prestige would be part of the battle along the fluid front of the cold war. From 1961 until the collapse of the Soviet Union in 1991, competition between the United States and the Soviet Union was a major influence on the pace and content of their space programs. Other countries also viewed having a successful space program as an important indicator of national strength.

Even before the first satellite was launched, U.S. leaders recognized that the ability to observe military activities around the world from space would be an asset to national security. Following on the success of its photoreconnaissance satellites, which began operation in 1960, the United States built increasingly complex observation and electronic-intercept intelligence satellites. The Soviet Union also quickly developed an array of intelligence satellites, and later a few other countries instituted their own satellite observation programs. Intelligence-gathering satellites have been used to verify arms-control agreements, provide warnings of military threats, and identify targets during military operations, among other uses.

In addition to providing security benefits, satellites offered military forces the potential for improved communications, weather observation, navigation, timing, and position location. This led to significant government funding for military space programs in the United States and the Soviet Union. Although the advantages and disadvantages of stationing force-delivery weapons in space have been debated, as of the early 21st century, such weapons had not been deployed, nor had space-based antisatellite systemsthat is, systems that can attack or interfere with orbiting satellites. The stationing of weapons of mass destruction in orbit or on celestial bodies is prohibited by international law.

Governments realized early on that the ability to observe Earth from space could provide significant benefits to the general public apart from security and military uses. The first application to be pursued was the development of satellites for assisting in weather forecasting. A second application involved remote observation of land and sea surfaces to gather imagery and other data of value in crop forecasting, resource management, environmental monitoring, and other applications. The U.S. and Soviet governments also developed their own satellite-based global positioning systems, originally for military purposes, that could pinpoint a users exact location, help in navigating from one point to another, and provide very precise time signals. These satellites quickly found numerous civilian uses in such areas as personal navigation, surveying and cartography, geology, air-traffic control, and the operation of information-transfer networks. They illustrate a reality that has remained constant for a half centuryas space capabilities are developed, they often can be used for both military and civilian purposes.

Another space application that began under government sponsorship but quickly moved into the private sector is the relay of voice, video, and data via orbiting satellites. Satellite telecommunications has developed into a multibillion-dollar business and is the one clearly successful area of commercial space activity. A related, but economically much smaller, commercial space business is the provision of launches for private and government satellites. In 2004 a privately financed venture sent a piloted spacecraft, SpaceShipOne, to the lower edge of space for three brief suborbital flights. Although it was technically a much less challenging achievement than carrying humans into orbit, its success was seen as an important step toward opening up space to commercial travel and eventually to tourism. Nearly a decade after SpaceShipOne reached space, several firms were poised to carry out such suborbital flights. Suggestions have been made that in the future other areas of space activity, including remote sensing of Earth, utilization of resources found on the Moon and near-Earth asteroids, and the capture of solar energy to provide electric power on Earth, could become successful businesses.

Most space activities have been pursued because they serve some utilitarian purpose, whether increasing knowledge, adding to national power, or making a profit. Nevertheless, there remains a powerful underlying sense that it is important for humans to explore space for its own sake, to see what is there. Although the only voyages that humans have made away from the near vicinity of Earththe Apollo flights to the Moonwere motivated by Cold War competition, there have been recurrent calls for humans to return to the Moon, travel to Mars, and visit other locations in the solar system and beyond. Until humans resume such journeys of exploration, robotic spacecraft will continue to serve in their stead to explore the solar system and probe the mysteries of the universe.

Apollo | space program | Britannica.com

Apollo, Moon-landing project conducted by the U.S. National Aeronautics and Space Administration in the 1960s and 70s. The Apollo program was announced in May 1961, but the choice among competing techniques for achieving a Moon landing and return was not resolved until considerable further study. In the method ultimately employed, a powerful launch vehicle (Saturn V rocket) placed a 50-ton spacecraft in a lunar trajectory. Several Saturn launch vehicles and accompanying spacecraft were built. The Apollo spacecraft were supplied with rocket power of their own, which allowed them to brake on approach to the Moon and go into a lunar orbit. They also were able to release a component of the spacecraft, the Lunar Module (LM), carrying its own rocket power, to land two astronauts on the Moon and bring them back to the lunar orbiting Apollo craft.

The first manned Apollo flight was delayed by a tragic accident, a fire that broke out in the Apollo 1 spacecraft during a ground rehearsal on January 27, 1967, killing all three astronauts. On October 11, 1968, following several unmanned Earth-orbit flights, Apollo 7 made a 163-orbit flight carrying a full crew of three astronauts. Apollo 8 carried out the first step of manned lunar exploration; from Earth orbit it was injected into a lunar trajectory, completed lunar orbit, and returned safely to Earth. Apollo 9 carried out a prolonged mission in Earth orbit to check out the LM. Apollo 10 journeyed to lunar orbit and tested the LM to within 15.2 km (50,000 feet) of the Moons surface. Apollo 11, in July 1969, climaxed the step-by-step procedure with a lunar landing; on July 20 astronaut Neil Armstrong became the first human to set foot on the Moons surface.

Apollo 13, launched in April 1970, suffered an accident caused by an explosion in an oxygen tank but returned safely to Earth. Remaining Apollo missions carried out extensive exploration of the lunar surface, collecting 382 kg (842 pounds) of Moon rocks and installing many instruments for scientific research, such as the solar wind experiment, and the seismographic measurements of the lunar surface. Apollo 17, the final flight of the program, took place in December 1972. In total, 12 American astronauts walked on the Moon during the six successful lunar landing missions of the Apollo program.

A chronology of spaceflights in the Apollo program is shown in the table.

What are the benefits of space exploration – Answers.com

The primary benefit is the survival of the human species, and that's the only one that really matters; for all others pale in comparison. Possibly within the next 100 years, probably within the next 10,000 years, and definitely within the next 10 million years, the earth wil no longer be able to sustain human civilization, and we'll have to leave. But more importantly, unless we spread out and populate other planets and moons around ours and other suns, our fate as a species wil be tied to one world, one sun. When the earth dies, we'll die with it; but even before then it may kill us. Until we colonize space, fill the universe with our progeny, we are bound to the same cycle of extinction that's claimed 99% of all species that have ever existed. We are a dying species: Maybe we're already dead. So, to answer your question, the main benefit of space exploitation is human survival. It isn't about money, pride, knowledge, or power, it's about our future. Think about that the next time the republicans cut Nasa's funding.

New Mexicos Sad Bet on Space Exploration – The Atlantic

Soon after departing the small resort town of Truth or Consequences, New Mexico, the video monitors on the bus come to life. Stars glitter in the night sky, a mystical flute soundtrack lilts, and a narrators voice intones: All that you see around you was at the bottom of the sea. The Conquistadors named the flat desert basin that formed after the sea receded Jornada del Muerto, or Journey of the Dead Man. As the bus lumbers through it, the narrator chronicles humanitys fixation with the mysteries of the sky.

This is the road to Spaceport America, which bills itself as the worlds first purpose-built commercial spaceport. But to believe the tourist-bus video, its not just a dormant industrial park erected with the promise of economic revitalization. Its the latest stop in humankinds ageless reach for the stars.

Spaceport America lies about 20 miles southeast of Truth or Consequences, roughly 50 miles north of Las Cruces, and at a perpetually indeterminate moment in the near future. Although the spaceport has been flight-worthy since 2010, the first launch by its anchor tenant, Virgin Galactic, still hasnt taken off. While the private space industry appears to be at a major turning point elsewhere in the world, its impacts havent quite reached the small New Mexico cities banking on its future. There arent many places where a spaceport like this, meant to service an international community, is feasible. Given the states large and controversial investment in the project, its success or failure might have broad impact on private space travel.

A New Mexico spaceport is only the latest entry in a triumphant time line of military and aerospace innovation in this southwestern state. Our video narrator speeds through Spanish colonialism and westward expansion to highlight the Manhattan Projects work in Los Alamos, to the north, and Operation Paperclip, a secret program that recruited German scientists to the United States after World War II. Among them was Wernher von Braun, who brought his V-2 rockets to the state.

White Sands Missile Range, a 3,200-square-mile military-testing site in South Central New Mexicos Tularosa Basin, hosted much of this work. Its home to the Trinity Site, where the first atomic bomb was detonated, and von Brauns rocket testing site, too. Spaceport America is positioned adjacent to the Army property, in a tightly protected airspace. That makes rocket-ship testing a lot easier.

Money is another reason Spaceport America finds itself here. In 2006, thenNew Mexico Governor Bill Richardson struck a partnership with Richard Bransons Virgin Galactic to build the companys headquarters in New Mexico. The state paid for the $220 million in construction costs with public funds, some of which came directly from neighboring Doa Ana and Sierra counties via gross-receipts-tax increases. Those taxes are expected to deliver nearly $75 million by 2029. In exchange, the locals long for economic opportunity. They could use it; according to U.S. Census data, Sierra County has one of the lowest median household incomes of the 33 counties in the state of New Mexico.

Mandy Guss, a business-development administrator with the City of Las Cruces, is optimistic about the spaceports potential impact on the citys future and identity.* It feels exciting, its like the future is now, she says. I think its something thats going to put Las Cruces and our region on the map. In addition to the ripple effects of about 90 projected Virgin Galactic employees relocating to Las Cruces (as of last summer, 21 were already there), the city eagerly anticipates more aerospace companies setting up shop at the spaceport and in Las Cruces.

Steve Green, the mayor of Truth or Consequences, recognizes that a town of less than 6,500 primarily known for its hot springs (the city changed its name from Hot Springs in 1950, in homage to a popular quiz show; locals call the place T or C) isnt likely to see the same population spike: I am realistic enough to understand that Las Cruces will get the lions share of the people who are coming there. We will get the people who dont want the big-city life. But Green is bullish on the tourism opportunities the spaceport will bring once the commercial spaceflights begin.

If they begin. For now, the spaceport is a futurist tourist attraction, not an operational harbor to the cosmos. The tour buses depart from a former T or C community center twice a day every Saturday. They pass thrift stores, RV parks, and bland but durable-looking structures, defiant underdogs against the mountains. We pass the Elephant Butte Dam, a stunning example of early-20th-century Bureau of Reclamation engineering that made it possible for agriculture to thrive in southern New Mexico; even so, a fellow spaceport tourist notes that the water levels seem far lower than what he recalls from childhood.

Spaceport Americas architecture involves monolithic concrete domes and curved forms in weathered earth tones, unobtrusively impressive, like an architectural humblebrag. The complex and its buildings vaguely recall a Southwest landmark frequently mistaken for the city of the future: Arcosanti, the architect Paolo Soleris 1970 urban laboratory nestled in the mountains north of Phoenix. Its oddly fitting: Soleri imagined a sustainable desert utopia, as well as speculative space arcologiesself-sustaining architectural ecologies, delicately rendered as hypothetical asteroid-belt cities or prototype ships.

At times, the spaceport feels as much like a prototype as Soleris drawings. The official tours are daytime weekend affairs, so when we enter the Operations Center on the weekly Saturday tour it feels empty. We are told that work happens at the spaceport, but theres little sign of it. At the Virgin Galactic office building, masking tape marks the carpet floors, perhaps in anticipation of future furniture arrangements. The only spacecraft we see on the tour is a model of Virgin Galactics SpaceShipTwo, glimpsed from a distance in an otherwise empty hangar. Even the spacecraft isnt real.

Admittedly, the name Spaceport America suggests theatrics. There are several commercial spaceports throughout the United States, some of which sport more activity and tenants. Most of Virgin Galactics testing has happened at the Mojave Air and Space Port; Virginias Mid-Atlantic Regional Spaceport recently signed on the SpaceX competitor Vector as a customer.

Others, like Oklahomas Air and Space Port, seem to be even more like ghost towns than this one. But New Mexicos gambit suggests we are at the spaceport of the nation. It doesnt feel like the frontier of private space travel so much as a movie set.

Its a quintessential American desert trope: the future as rehearsal rather than reality. Many promises for technologies of future urbanism start as desert prototypes. Hyperloop Ones test track in the Nevada desert; self-driving cars tooling around Tempe, Arizona; and Bill Gatess Belmont, Arizona, smart-city pilot offer a few more recent examples, but that tendency to treat the desert as blank canvas for constructing utopia resonates from the Mormon state of Deseret to Burning Mans Black Rock City. New Mexico examples tend to include slightly more dystopian rehearsals: Much of the states existing science and defense industries emerged from bringing Manhattan Project scientists to what, at the time, was the middle of nowhere to test nuclear weaponsessentially, to practice ending the world.

Spaceport America hasnt done much rehearsing, yet (although it has, in fact, been literally used as a movie setmost recently for the 2017 sad-teen-from-Mars feature The Space Between Us). Following a disastrous 2014 test flight in the Mojave desert that left the pilot seriously injured and the copilot dead, Virgin Galactic postponed its plans while addressing what the National Transportation Safety Board called a failure to consider and protect against the possibility that a single human error could result in a catastrophic hazard. A successful flight in January 2018 has restored some confidence that, at long last, space tourism really is around the corner. Down in Las Cruces, Guss expressed cautious optimism. Youll always have a lot of folks who, you know, wont believe it till they see it. But overall people are hopeful and excited.

Notwithstanding Virgin Galactics absence, there is a lot already happening at the spaceport. The tourism at the heart of the Spaceport America pitch hasnt yet materialized, but meta-tourism like the Saturday tours provide some revenue, and the aerospace industry has been active here. Google tested its SkyBender project to beam high-speed internet via drone there. Spaceport America boasts of its 39 vertical launches and seven horizontal launches, which have included launches by UP Aerospace in partnership with White Sands and the launching of various human cremains into space by the memorial spaceflight provider Celestis. On the tour, one of the firefighters on-site points to a hangar rented by Boeing holding the CST-100 Starliner, a space capsule the company is testing.

Aerospace successes outside of New Mexico are also encouraging to the spaceports supporters: Shortly after my visit, SpaceXs Falcon Heavy rocket successfully launched Elon Musks Tesla into orbit, along with even greater optimism for the future of the private space industry. (SpaceX was briefly slated to be a regular Spaceport America tenant but has since shifted its ambitions toward a private site in Brownsville, Texas.)

But when its not inviting the public to take in a spectacle, the space industry treats most of its activities as closely guarded trade secretsso much so that the spaceports public financing and ownership has been deemed a major liability. This was the reason that the New Mexico legislature voted overwhelmingly in favor of a bill that gives the spaceport significant exemptions from public-records requests. The Spaceport America CEO, Dan Hicks, argued that companies that might have come to New Mexico were choosing competitor sites out of fear that competitors could glean information about their R&D through records requests. The legislature agreed; during the same session, it also allocated $10 million to Spaceport America for a new hangar and additional operations.

Some last-minute revisions to the bill appeased government-transparency advocates, but the exemptions are subject to Spaceport Americas interpretation. Its unclear, for example, whether Spaceport America could exempt tenants from disclosing information about toxic chemical spills or other environmental disasters (an attempted amendment on this issue by the state legislator Jeff Steinborn failed to pass). Spaceport America acknowledges the validity of the concerns but insists that the bill as passed effectively addresses them.

For the cities that view the spaceport as potentially economically transformative, the records-request exemptions are seen as a cost of doing business. I think that New Mexico has to grow up, Green, the T or C mayor, told me when asked about the potential slippery slope of giving exceptions to publicly financed projects. I dont see why the public has to know what SpaceX or Boeing or Virgin Galactic are doing, what technology theyre dealing with. Thats their business. You want to know about it? Buy their stock.

The NMPolitics.net editor Heath Haussamen, who has been reporting on the public-records issue, believes success isnt predicated on secrecy. I hope the spaceport works, he says. Ive lived here all my life. My daughters six years old. And New Mexicos greatest export is our childrenwe do a great job of giving them college degrees and not giving them opportunities in the state. He appreciates the efforts the state has made to think longer term about the spaceports impact; a portion of the taxes paid by Sierra and Doa Ana County, for example, are dedicated to expanding and supporting STEM education in the counties schools. Haussamen believes Spaceport America could help revitalize the southern New Mexico economy, but he also believes that the public has a right and a duty to be able to know what kind of return theyre getting on their investment.

Perhaps the insistence on secrecy for its tenants explains why Spaceport Americas marketing materials, along with conversations on the official tour, still emphasize Virgin Galactics space-tourism business. Passengers who can afford the $250,000 fare spend several minutes in zero gravity before returning to Earth. Its a far cry from democratizing space travel and pretty unlikely to be the primary source of Spaceport Americas revenue. Virgin Galactics notable absence at the spaceport makes these crewed missions seem like stunt more than science, but most of my fellow tourists take the premise of ubiquitous space travel to colonies on Mars as a fait accompli. Im not sure why people in a desert would fantasize about going somewhere even harder to inhabit.

But the mythologies of the former American frontier tend to collide with the final frontier: As extreme environments, deep space and remote desert have a lot in common. That explains projects like Utahs Mars Desert Research Station, a faux-Martian habitat for long-duration fieldwork for a hypothetical, future Martian expedition. Humanity dreams of going to space for many of the same reasons some people went to the desert: because it is there, because they hope to get rich extracting natural resources they find there, and because they suspect mysterious, new terrains cant be any worse than the irredeemable wreckage of the landscape theyre leaving behind. In a region defined by boom-and-bust cycles of mining and oil and gas, where the future has always been in part determined by the art of water-rights negotiations, and where climate change presents a very real threat (more than half of the state of New Mexico is currently experiencing severe drought), believing in the inevitability of Mars colonies is maybe no less idealistic than believing in the Southwest itself.

This is perhaps the most unavoidable and disconcerting truth of Spaceport America. The romance and promise of the American West was built, in part, on federal land grants to private corporations that promised to bring boomtowns to places previously otherwise deemed uninhabitable wastelands. Cities rose and fell with the rerouting of railroads; a major turning point in Las Cruces own history came when the city sold right-of-way to the Atchison, Topeka, and Santa Fe Railway in the 1880s, making the city part of a crucial industrial thoroughfare.

To manifest destinys proponents, to doubt the inevitability of technological and social progress via the railroad was tantamount to doubting the will of God. Today, questioning the value of (mostly) privately funded space development likewise feels like doubting human progress. Spaceport America isnt all that different from the railroad and mining executives building company towns that it cites in its own promotional literaturewhich is to say, it uses the promise of progress as a smoke screen from very real concerns over taxpayer funding and public accountability. The romance of space distracts from the reality that at the end of the day, Spaceport America is a publicly financed resource mainly serving private companies, built on a long-stalled promise of bringing new money and a daring new tech industry to a jobs-hungry and very poor region. The price tag and PR rhetoric may differ from that of cities engaged in bidding wars over a Facebook data center or a new corporate tech campus, but concerns over public concessions to private-industry demands for secrecy and tax breaks (along with questions of whether the projects benefits will actually be felt by residents who need them the most) remain more or less the same.

On the bus ride back to the Truth or Consequences visitors center, yet another video celebrates the possible democratization of space through the can-do efficiency of the private sector. New Mexico, we are reminded, has been part of that journey this whole time, from petroglyphs to spaceships. Perhaps Spaceport America is part of a grand southwestern historybut a fraught history, and one that provides no guarantee of inevitable success. Whether on the empty spaceport runway or driving across New Mexico, Arizona, Utah, Nevada, or California, it is hard to escape the ghosts of the Wests promised cities of tomorrow among its present cities hanging onto borrowed time.

Watching a group of bored cows on the Jornada del Muerto as Spaceport America recedes into the distance, I wonder if the future always feels like rehearsal until it arrives, or if it is always rehearsal, only seeming like it has arrived when the run-through loses its novelty. Maybe all of the impatient skeptics will be proven wrong this year, and the future will finally arrive at Spaceport America. Here in the desert, a better future always seems to be right around the corner.

Celebrating Space Exploration – Science NetLinks

On July 29, 1958, President Eisenhower signed into law the National Aeronautics and Space Act, which provided federal funding for research into space flight. Just over two months later, on Oct. 1, the National Aeronautics and Space Administration (NASA) began operations. They responded quickly to the gauntlet thrown down by the Soviet Union with the 1957 launch of Sputnik and set to work exploring the universe around us. A little more than a decade after being created, NASA successfully sent men to the Moon.

Inspired by every new victory and challenged by each setback, NASA continues to explore the limits of space, sending regular missions out to seek new answers about what lies beyond our ken. These include the ongoing construction of the International Space Station, missions (such as Galileo, Cassini/Huygens, and Messenger) to explore the other planets of our solar system, explorations of comets and asteroids, and mapping the universe using satellites and telescopes from around the world.

These Science NetLinks resources provide a variety of rich media learning experiences to help students learn more about NASA and discover the history and future of space travel.

Science has barely scratched the surface of space exploration … – Kearney Hub

KEARNEY Despite being able to give finite predictions for solar events such as the eclipse, science has just barely scratched the surface of space exploration, a visiting astronomer to Kearney explained to a room full of space fans.

Assistant professor of physics and astronomy at Louisiana State University Tabetha Boyajian gave a presentation on eclipses Sunday, the eve of the Great American Eclipse, at the Merryman Performing Arts Center.

I tried to take that (presentation) to not just talking about the solar eclipse and why its happening (today) but try and put that in the perspective of the whole universe, Boyajian said.

Eclipses arent unique to Earth, Boyajian explained to a full crowd. These special alignments occur throughout the solar system and all through the galaxy whether its a moon blocking light from the sun or a planet going in front of a star, which is referred to as a transit.

Science is the ability to predict certain things, and were able to do it for the eclipse because weve studied it for thousands of years and were able to predict these things down to very, very fine positions and measurements, Boyajian said. Space as a whole is very unexplored, and were just kind of scraping the surface of these kind of things that we can discover in space and thats really exciting.

Boyajian, who gave a TEDTalk on her work, earned her doctorate from Georgia State University and was awarded the Hubble Fellowship. After continuing her research at Georgia State for three years, she did her postdoctorate at Yale University. It was there that she become part of the Yale Exoplanet Group.

My research interests are primarily in nearby stellar systems and those with planets going around them what we call exoplanets and trying to detect them.

Her work focuses on the unknown specifically KIC 8462852, a mysterious star that displays odd behavior.

Its surprising because it doesnt do the things that stars do or that we think that stars do, Boyajian said.

The star shows variations in brightness, which have caused scientists to hypothesize scenarios from comet dust to alien megastructures.

Despite results they receive on the bizarre star, however, the data still hasnt pointed scientists down the right track, Boyajian said.

Nature is a lot more creative than we are. Theres no way of telling what its going to throw at us next.

NASA: We Need Companies Like SpaceX for the Future of Space Exploration – Futurism

A Different Path to Space

On Monday, August 14, SpaceX launched a resupply mission to the International Space Station (ISS). It was the 12th resupply flight SpaceX has done for NASA as part of its Commercial Resupply Services (CRS) program, and the last one with an unused Dragon capsule. It has also been a month since Elon Musks rocket company flew to space, after a series of successful launches earlier this summer. This most recentCRS-12 flight was a special one, both for NASA and SpaceX, but also for the future of space exploration.

A great many recent rocket and spaceflight achievements have been madeby commercial space companies like SpaceX and Orbital ATK (formerly Orbital Sciences). Both companieshave been running CRS missions for NASA, as well as aeronautics giant Boeing. Theres also Jeff Bezos Blue Origin which is also working on reusable rockets, Virgin Galactic with its more space tourism-focused approach, and many more space endeavor focused startups.

NASA acting administrator Robert Lightfoot, Jr. is convinced that these private, commercial companies are actually the future of space exploration or at least, theyll make it possible. Today epitomizes what we have been doing for a long time in terms of building our commercial partnerships, Lightfoot told Futurism after Mondays launch. We are getting to space a little differently than we used to. Its not just us anymore by ourselves. Weve got a great partnership with SpaceX. Weve got a great partnership with Orbital ATK.

While commercial space companies may have their own plans for space exploration most of which involve returning to the Moon and getting to Mars it doesnt mean that NASA doesnt haveplans of its own. In fact, NASA has been working on its own mission to Mars for a while now. The space agency is also currently building its own large rocket. However,recent developmentssuggest that NASA needs all the help it can get for its programs to survive.

Such a collaboration between NASA and commercial space agencies has been working well, Lightfoot noted. For one, its whats made it possible for the ISS to continue operating. They have allowed us to keep the space station going and allowed us to do some fantastic research, he said, referring to SpaceX and Orbital ATKs CRS missions.

Lightfoot also suggested that these partnerships could do so much more, like sending people to space again. SpaceX and Boeing will come along and allow us to fly [a] crew, he said. In a couple of years we will get there, and they will be getting crew to the station.this will give us our own access to space. From there on, the possibilities could be endless.

Indeed, space exploration is entering a new era. It isnt necessarily ending the era when space agencies were the only ones making giant leaps for mankind only helping it. Collaboration is the future of space exploration.
