AMARILLO, Texas (KAMR/KCIT) Joan Higginbotham began her career at NASA in 1987 as a payload electrical engineer at the Kennedy Space Center(KSC) in Florida.

During her nine-year tenure there, she participated in numerous space shuttle launches from the firingroom, the nerve center for launches an impressive accomplishment for anyone. However, when she returned to KSC for the launch of Space Shuttle Discovery on STS-116, a 12-day mission to the International Space Station, she took participation to a whole new level: as astronaut Joan Higginbotham. To date, she is the third of only three African American women astronauts to fly in space.

For astronauts like Joan, performing common tasks that we take for granted here on Earth, can be quite challenging in space. Take exercising for instance. Astronauts in space exercise up to 14 hours a week to stay healthy, and their clothes take a beating. This is one of the examples of why NASA is teaming up with P&G to create and learn about new innovations that efficiently clean clothing within constrained environments. The partnership will help unveil breakthrough insights and power future innovations within the next decade. NASA Tide, a detergent, is being developed specifically for use in space to help combat challenges, such as malodor, cleanliness and stain removal, all while ensuring the laundry water output can be recycled for re-use as drinking water. Products like this will be used to advance environmentally friendly, low-resource-use laundry solutions here on Earth.

Tide will also be a part of the future Artemis Moon and Mars Missions to help develop cleaning solutions for even longer duration crewed missions.On June 23, Joan Higginbotham will be available to discuss how more sustainable solutions in space can lead to practical, impactful solutions here at home. Shell also share memories of her spaceflight and what she expects to see from the NASA space program in the years to come.

Former Astronaut on How Space Exploration is Helping Earth - KAMR - MyHighPlains.com

Since the dawn of human civilisation, weve been explorers looking for food, shelter, and safety. We dared to walk past uncharted territories filled with imminent mortal threats and unfamiliar landscapes. But our urge to explore never diminished and hence we kept exploring our planet. We invented agriculture, made settlements, built civilizations and kept our quest for more alive.

A group of tribes in the Pacific islands dared to cross the ocean which was of great risk during that time. However, natural disasters like frequent volcanism, earthquake, shortage of food and overwhelming population forced them to take the risk. As their ship drifted towards uncertainty for weeks, they were expecting to see a new world, and to their surprise, they stumbled upon a remote island in the Pacific where they settled down. That baby step ushered in the newfound urge for exploration. Curiosity overtook fear and the explorers discovered new islands scattered all over the Pacific.

Fast forward to the present, we still have explorers looking at a different scenario, the cosmic ocean. During the Cold War which later culminated into the Space Race, Russia and the United States began to test launch vehicles. Russia took a lead by putting the first satellite Sputnik 1 in orbit around Earth and the US put an end to it by sending 12 astronauts on the moon during the Apollo missions. Neil Armstrongs stepping on the moon was very significant, not only for human spaceflight but also for the overall vision of space exploration. The men on the Apollo program saw Earth like never before. Space race began as a battle of superiority but it gave rise to the dawn of space exploration.

Today researchers are developing theoretical concepts on interplanetary/interstellar space flight. However, our first stop is always the moon. Making a habitat on the moon will have a lot of challenges. Since there is no atmosphere, let alone greenhouse effect, the habitat housing future lunar astronauts will be vulnerable to the temperature fluctuations (ranging from -153 degrees Celsius at night to 107 degrees celsius during the day but not much to feel as there isnt any atmosphere) as the moon goes through its own day-night cycles. The gravity on the lunar surface is one-sixth that of earth and this will also have an effect on astronauts planning to stay there. Astronauts might have to deal with the loss of bone density and muscle strength but scientists are optimistic about finding a solution. Micrometeoroids and radiation will also be a major issues. However, with proper precautions and preparation, hazards can be avoided.

The International Space Station, an orbital habitat, the size of a football stadium will allow us to understand more about how weightlessness will affect astronauts on a mission to Mars and beyond. However, in order to counter the effects of micro-gravity or weightlessness, an external force could be used. A Stanford torus, which is a proposed design by NASA might have a solution. A Stanford torus is an orbiting habitat consisting of a ring which will rotate once every minute so that the inmates have access to artificial gravity. The centrifugal force (outward pulling force) will make the inmates feel as if theyre feeling the surficial gravitational attraction. Space exploration has received a lot of criticism lately because of the problem it has with the financial perspective and also based on the necessity to do the same. But just like the tribes living in the Pacific islands did, oneday we will have to venture into the deep cosmic ocean. Till today weve only dampened our toes but oneday we might have to wade deeper. Either we become spacefaring or extinct.

Space exploration will have a greater risk and it might not be feasible but human spaceflight is a necessity to ensure the existence of humans. And considering the progress of science over the past few decades, we can hope for a better tomorrow, and for a better tomorrow we need to be the pioneers who can ensure a better tomorrow. Earth might just be the perfect home with a nourishing atmosphere, a protective magnetic field and an awesome interplanetary neighbourhood but permanence is not a rule of the cosmos and hence we have to continue being the pioneers.

The Urge And Necessity Of Space Exploration - Barak Bulletin

NASAs Human Landing System (HLS) program is the biggest bet the agency has made on the commercial space industry since the commercial crew program a decade ago. NASA decided to procure landing services rather than the landers themselves, awarding a $2.9 billion contract to SpaceX April 16 to fund development of a lunar lander based on the companys Starship vehicle and fly one demonstration mission with astronauts.

That approach has attracted plenty of scrutiny and criticism. The award to SpaceX is on hold as the Government Accountability Office evaluates protests filed by two losing bidders, Blue Origin and Dynetics. A bill passed by the Senate June 8 would require NASA to select a second company, although with no guarantee that the funding will be there to support both companies.

HLS may be the biggest example of NASA buying services to support the Artemis program, but it is not the only one. Even as some cornerstones of Artemis Orion, the Space Launch System and the Gateway move forward under conventional contracts where NASA owns and operates the hardware, its making greater use of service contracts to acquire the other things it needs to explore the moon, from landers and communications to even the spacesuits the astronauts will wear on their moonwalks.

HLS is not NASAs first lunar lander services program. In 2018, NASA unveiled the Commercial Lunar Payload Services (CLPS) program, where the agency would buy payload space on commercially developed robotic lunar landers.

The idea was to provide frequent and inexpensive access to the moon for experiments and technology demonstrations, particularly those with a higher tolerance of risk. Agency officials often talked about taking shots on goal with CLPS, with the expectation that not every shot would make it in.

Fourteen companies have received NASA contracts through CLPS, making them eligible to bid on task orders for delivery missions. Four companies have won the six task orders NASA has issued to date: Astrobotic and Intuitive Machines each won two, along with Firefly Aerospace and Masten Space Systems. Their missions range from transporting scientific instruments that had been sitting on the shelf waiting for a ride to VIPER, a NASA rover the size of a golf cart that will search for ice deposits at the lunar south pole.

CLPS is also a pathfinder for buying services for lunar exploration. The big thing here is that were starting to work more closely with the commercial community, said Jake Bleacher, chief exploration scientist at NASA. CLPS is our first step on that front.

That has become a learning experience for both NASA and the companies as they get used to different ways of doing business. Some scientists who have experiments flying on CLPS missions have privately complained that NASAs approach of buying payload space on commercial landers shifts the technical burden, and costs, onto researchers. They now have to come up with their own solutions to engineering issues like thermal control that would, in a traditional approach, be handled in a more integrated fashion.

A services approach also doesnt prevent delays. When NASA made the first CLPS awards in May 2019, the three winners Astrobotic, Intuitive Machines and Orbit Beyond promised to launch their missions by the middle of 2021. But Orbit Beyond, whose lander was going to be the first to launch in September 2020, returned its award two months later because of what NASA called internal corporate challenges.

Intuitive Machines saw its first Nova-C lander mission slip slightly from July to October 2021. However, in a Federal Communication Commission license application filed in April, the company revealed its launch had been delayed to no earlier than the first quarter of 2022. The company blamed the delay on its launch provider, SpaceX, who said that unique mission requirements forced the delay.

Astrobotic, which originally was going to launch its Peregrine lander in June 2021, is still hoping to launch before the end of the year. It will fly on the inaugural Vulcan Centaur rocket from United Launch Alliance, whose development has been delayed by issues with its BE-4 main engine. ULA has suggested that customer payload delays, and not Vulcan issues, would delay its first launch with the Peregrine lander into 2022.

John Thornton, chief executive of Astrobotic, said at a June 9 event that the Peregrine launch is coming very soon but wasnt more specific.

There have been proposals to expand the CLPS program to include orbiters or even sample return missions. However, the next frontier for commercial services at the moon may involve infrastructure.

NASA is studying a concept it calls LunaNet: a network of satellites that would relay communications and provide navigation information for spacecraft on or around the moon. Current and proposed missions can communicate directly to Earth, but increasing lunar traffic will strain existing ground networks, and wont work for missions on the lunar farside, where Earth is out of view.

Our philosophy is that each mission should not have to create its own communications and navigation infrastructure. Thats not efficient, said Andy Petro, lunar communications and navigation implementation lead at NASA Headquarters. We see having an infrastructure to provide those services lowers the barrier to entry for new missions and capabilities.

Exactly what LunaNet will look like is unclear, as the project is still in its earliest phases of development. The idea of having relays this early was not anticipated, he said at a meeting of a Space Studies Board committee in April. Interest in doing missions on the far side of the moon, as well as exploration of the polar regions where direct-to-Earth communications can be difficult, accelerated planning for a communications network.

However, its unlikely that LunaNet would be a conventional NASA program. Were looking at doing something that NASA would not necessarily build and operate, but through either commercial public private partnerships or service contract arrangements, quite possibly from multiple providers, he said.

In a request for information (RFI) last October, NASA asked for details from potential commercial service providers for lunar communications and navigation. That included not just technical capabilities but also cost estimates and the potential for partnerships and options for financing the system.

Petro said at the April meeting that NASA is still working on an acquisition strategy for LunaNet. I dont expect it to be the traditional development and procurement that weve done in other cases.

NASA is not the only agency looking at commercial approaches to lunar communications and navigation. On May 20, the European Space Agency announced it issued study contracts to two consortia, one led by Surrey Satellite Technology Ltd. (SSTL) and the other by Telespazio, for an initiative called Moonlight. The two groups will spend the next 12 to 18 months studying concepts for satellite networks around the moon for communications and navigation.

Moonlight could be a flagship European project to create the first operational comms and navigation system around the moon, David Parker, ESAs director of human and robotic exploration, said at a briefing about the contracts.

The goal, he emphasized, is to create a commercial system, one developed in partnership with ESA but offering services to others. That will be part of the initial Moonlight studies: the feasibility of the system but also the business case, Parker said. The studies will be done in time for ESA to decide whether to seek support for the program at its next ministerial meeting in late 2022.

SSTL has a head start. It is developing a spacecraft called Lunar Pathfinder scheduled for launch in 2024 that will provide commercial communications relay services. It will operate in an elliptical orbit providing coverage over the south polar regions of the moon, using UHF and S-band links with spacecraft on the lunar surface and X-band for communications with Earth.

Were creating this shared communications and navigation network for the moon that we believe will undoubtedly act as a catalyst to inspire more exploration missions, said Phil Brownett, managing director of SSTL.

ESA officials said NASA was aware of Moonlight but added that having multiple networks of communications and navigation satellites at the moon could have benefits provided there was some degree of interoperability, like that between the GPS and Galileo satellite navigation systems.

Petro said NASA also supported interoperability. Were promoting this idea of mutually agreed-upon standards among a set of cooperating networks, he said, which could go beyond communications and navigation to other services, like solar storm warnings. We think this could be introduced as part of the earliest missions.

NASA is also examining how it can use services, rather than conventional contracts, for the spacesuits it will need for future Artemis missions. NASA previously announced plans to develop a new spacesuit, called the exploration extravehicular mobility unit or xEMU, that astronauts will wear on the lunar surface.

However, in an April 14 RFI, NASA said it was considering moving to a services model for those suits. One or more companies would produce, own and maintain the suits, with NASA effectively renting them as needed for missions. The same approach could also be used for spacesuits needed for International Space Station spacewalks.

We are always looking at ways to lower costs for the taxpayer and focus our efforts and resources on future technology and our bold missions in deep space, said Mark Kirasich, head of NASAs Advanced Exploration Systems division. We hope to receive industry input on the feasibility of shifting our exploration spacewalk acquisition activities to a service-based model like our procurement for commercial cargo and crew services.

NASA will continue its own design work on the xEMU suit and share that information with industry, but companies would be able to develop their own designs that meet NASA requirements.

Responses to the spacesuit RFI were due to NASA at the end of April. A draft request for proposals could be released in mid-June, according to a tentative schedule included in the RFI, with a contract award as soon as the end of the calendar year.

All these efforts by NASA and other agencies to procure services, rather than spacecraft and other hardware, are driven by the belief that doing so can save time and money for governments and give companies the flexibility to offer similar services to other customers.

In a June 9 talk in Pittsburgh, after visiting the headquarters of Astrobotic, Thomas Zurbuchen, NASA associate administrator for science, explained that Artemis was pairing science and exploration with the entrepreneurial spirit exemplified by Astrobotic and others in the CLPS program.

Combining those would create a lunar program that weve never seen before and open the path for Americans to go back to the surface of the moon later this decade, he said.

Lunar Exploration as a Service: From landers to spacesuits, NASA is renting rather than owning - SpaceNews

Many people may not know that NASA has a vast catalog of free software available for anyone to download. Most of the software it offers was originally developed to help space exploration, and the programs are available for people to download for other uses here on Earth. The software catalog has hundreds of programs and more than 180 new applications, all available at no cost.

NASA says that its programs have been adapted and used by government agencies, entrepreneurs, researchers, and other users. Among the software is a program called TetrUSS which is a computational fluid dynamics program developed at NASA. The software was originally designed to allow engineers to study the shape of an aircraft to minimize drag and maximize fuel efficiency. The program is available in the US and is one of the most downloaded applications in NASA history.

NASA says that TetrUSS has been used to design aircraft, cars, and boats as well as investigating architectural aerodynamics and to assist in aircraft crash investigations. Another popular application is called WorldWind. NASA admits that the volume of data its satellites capture can make the data difficult to use. WorldWind visualizes data NASA has gathered using a virtual globe of the Earth described as video game-like.

Users of the software can zoom from satellite altitude all the way down to any point on the planets surface. The software has been used to help manage resources all around the world. Its also used to support the Coast Guard by generating a map from live feeds of satellite and maritime data.

NASA says there are dozens of other environmental science programs available for download at no cost. Other tools include one to calculate a solar power systems size and power requirements using fuel cells, solar cells, and batteries. Another program can analyze solar aircraft concepts by evaluating their flight worthiness and providing design feedback. Currently, the NASA software catalog contains more than 800 programs and can be searched here.

Business moguls Sir Richard Branson and Jeff Bezos should be thanking ancient Greek astronomers for being able to realize their travel off the face of the earth and into space this month. Virgin Galactics Branson hopes to beat Amazon CEO Bezos to travel to space, announcing plans to be Astronaut 001 on the firms July 11 test flight.

As civilized societies were just learning to use the wheel on earth, the ancient Greeks were aiming at the sky and the stars, contemplating outer space and how to measure it.

Even the science of the study of the sky and the stars, astronomy, finds its root in the ancient Greek wordAstronomia.

It was under Greek skies that ancient astronomers began to develop theories about the planets overhead, theories that are now proven. Christopher Columbus may or may not have set out to prove that the earth was spherical, but it was the ancient Greek astronomer Aristarchus who initiated the theory that the universe is heliocentric and that the planets are round.

The Babylonians of Mesopotamia first looked to the skies and postulated that the stars, the moon and the sun as gods that ruled over men. However, it was the ancient Greeks who analyzed those theories of deities and turned them into mathematical equations and calculations.

If you really want to travel to the stars, there is an easier way than heading to Cape Canaveral, where NASA launches rockets from Florida into outer space, or getting an extraordinarily pricey ticket aboard the craft that Branson and Bezos will travel on this month.

If you can get to the Acropolis, just a few hundred meters away is the National Observatory, known in Greece as the Asteroskopeio. From the observatory, positioned directly across from the Acropolis on Lofos Nymphon in central Athens, you can get a birds eye view of Mars and the moon through the Doridis refractor telescope.

The National Observatory of Athens was founded in 1842, as the first research center of modern Greece. Its history is linked with the evolution of basic and applied research, the development of services provided to the Greek State and society at large, and the promotion of science.

And how amazing is it, that literally just steps away from where ancient Greek astronomers conducted their first experiments, contemporary Greek astronomers are working today and they can show you the planets in the night sky?

Metonas was a Greek mathematician, astronomer and engineer who lived in Athens in the 5th century BC. He is best known for the calculations he made for the Metonic cycle in 432 BC for the lunar calendar year of Attica.

Metonas calendar assumes that 19 solar years equals 235 lunar months, which equals 6,940 days. This system arose from calculations made by Metonas based on his own astronomical observations, which were confirmed by Aristarchus 152 years later.

According to the testimonies of ancient historians, Metonas installed the first Heliotropion, or Helioscope, in Pynx in Athens. The foundations of the Helioscope are still visible just behind the steps leading to Pnyx, the archaeological site perched on a small, rocky hill, just over 330 feet high in the center of Athens.

The site is in a large park, just below the National Observatory, to the west of the Acropolis. Metonas determined the dates of the equinoxes and the solstices based on the specific location of this helioscope.

From this position the sunrise during the summer solstice is seen from the top of Mt. Lycabettus, while six months later, during the winter solstice, the sun rises from the top of Mount Hymettus. The annual apparent movement of the sun on the horizon creates an arc of 60 degrees, the bisector of which is aligned with the rock of the Acropolis. The exact determination of the summer solstice was important to the ancient Athenians because the first moon, after the summer solstice, marked the beginning of the new year.

Metonas was one of many ancient Greek astronomers to formulate calculations while gazing at the skies above. Renowned mathematicians, many of these scholars, branched off in astronomy, cataloguing, calculating and observing. Whether they catalogued stars, contemplated shapes or tried to measure the physical space within and beyond the borders of earth, their work put contemporary man in the sky.

Today it is hard to believe in any other notion than spherical planets that revolve around the sun.

Pythagoras of Samos, who lived from 570 to 495 BC, was an ancient Greek astronomer and philosopher and the eponymous founder of Pythagoreanism. Pythagoras was credited with many mathematical and scientific discoveries in antiquity. Since at least the first century BC, Pythagoras has commonly been given credit for discovering the Pythagorean theorem in geometry, which states that in a right-angled triangle the square of the hypotenuse is equal (to the sum of) the squares of the two other sides.

It was said that he was the first man to call himself a philosopher, a lover of wisdom, in the Greek language, (philo/friend of sophia/wisdom). He was the first to divide the globe into five climatic zones.

In astronomy Pythagoras is credited with the belief that the earth is spherical and for identifying the morning and evening stars that we know today as the planet Venus. By the end of the fifth century BC, this fact was universally accepted among Greek intellectuals.

Philolaus, who lived from 470 to 385 BC, was a Greek Pythagorean and pre-Socratic philosopher. He was born in a Greek colony in Italy and migrated to Greece. Philolaus has been called one of three most prominent figures in the Pythagorean tradition and the most outstanding figure in the Pythagorean school.

Pythagoras developed a school of philosophy that was dominated by both mathematics and mysticism. Most of what is known today about the Pythagorean astronomical system is derived from Philolaus views. He may have been the first to write about Pythagorean doctrine.

Philolaus asserted that the earth was not the center of the universe, rebelling against the geo-centrism of the time. He is credited with the earliest known discussion of concepts in the development of heliocentrism, insisting the sun is the center of in the human universe.

Archimedes of Syracuse, who lived from 287 to 212 BC, was an ancient Greek astronomer, mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists of classical antiquity. The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape.

Archimedes principle involved a metal bar, placed into a container of water, on a scale. It displaces as much water as its own volume, increasing the mass of the containers contents and weighing down the scale.

A votive crown for a temple had been made for the king of Syracuse, who had supplied the pure gold to be used. Archimedes was asked to determine whether some silver had been substituted by a dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body to calculate its density.

Archimedes noticed while taking a bath that the level of the water in the tub rose as he got in. He realized that this effect could be used to determine the volume of the crown. For practical purposes, water is incompressible so the submerged crown would displace an amount of water equal to its own volume.

By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress himself, crying Eureka, which in Greek sounds like evreeka, literally meaning, I have found it!

The test on the crown was conducted successfully, proving that silver had indeed been mixed in with the gold.

Archimedes also explored astronomical measurements of the earth, the sun and the moon, as well as Aristarchus heliocentric model of the universe. Despite a lack of trigonometry and a table of chords, Archimedes described the procedure and instrument used to make observations, a straight rod with pegs or grooves, applied correction factors to these measurements, and finally gave the result in the form of upper and lower bounds to account for observational error.

Ptolemy, quoting Hipparchus, also references Archimedes solstice observations in the Almagest. This would make Archimedes the first known ancient Greek astronomer to have recorded multiple solstice dates and times in successive years.

Ptolemy, 335-405 BC, used an astrolabe to record astronomical observations.

Today we know the exact time, the positions to the stars and planets, and our exact location, to the tenth of a degree but all these things were available to the ancient Greeks as well, in one device, thanks to the invention of the astrolabe.

The scientistPtolemy, who lived in Alexandria, was the brilliant mind behind this genius machine, which used sets of dials to determine altitude, latitude as long as the time was known the shifting positions of stars and planets, and to survey or triangulate your location on land.

Basically, the astrolabe was a handheld model of the universe. Its many functions also made it an elaborate inclinometer and an analog calculation device that was capable of working out several kinds of problems in astronomy.

The importance of the invention of the astrolabe comes not only from the early discoveries in astronomy, but also in determining latitude on land or on calm water, making it possible to navigate the seas in a limited way.

Aristarchus of Samos,who lived from 310 to c.230 BC, was an ancient Greek astronomer and mathematician who presented the first known heliocentric model that placed the sun at the center of the known universe, with the earth revolving around the sun once a year and rotating about its axis once a day. Aristarchus identified the central fire with the sun. He put the other planets in their correct order of distance around the sun.

Aristarchus suspected that the stars were just other bodies like the sun, albeit farther away from earth. His astronomical ideas were rejected in favor of the geocentric theories of Aristotle and Ptolemy.

Aristarchus estimated the sizes of the sun and moon as compared to earths size. He also estimated the distances from the earth to the sun and moon. He is considered one of the greatest astronomers of antiquity.

Since Aristarchus suspected the stars were other suns that are very far away, there was no observable parallax that is, a movement of the stars relative to each other as the earth moves around the sun. Since stellar parallax is only detectable with telescopes, his accurate speculation was unprovable at the time.

It was not until the sixteenth century that a mathematical model of a heliocentric system was presented by the Renaissance mathematician, astronomer, and Catholic cleric, Nicolaus Copernicus, leading to the Copernican Revolution. In the following century, Johannes Kepler introduced elliptical orbits, and Galileo de Galilei presented supporting observations made using a telescope.

Eratosthenes of Cyrene, who lived from 276 BC to195 BC, was an ancient Greek astronomer who was also a multi-discipline scholar, or polymath. He was a mathematician, geographer, poet, astronomer and music theorist. He was a man of such learning that he also became the chief librarian at the Library of Alexandria. His work is comparable to what is now known as the study of geography, and he introduced some of the terminology still used in that discipline today.

Eratosthenes is best known for being the first person known to calculate the circumference of the earth, which he did by using the extensive survey results he could access in his role at the Library of Alexandria. His calculation was remarkably accurate. He was also the first to calculate earths axial tilt, which also proved to have remarkable accuracy. He created the first global projection of the world, incorporating parallels and meridians based on the available geographic knowledge of his era.

Eratosthenes was the founder of scientific chronology. He endeavored to revise the dates of the main events of the semi-mythological Trojan War, dating the Sack of Troy to 1183 BC. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers.

The measurement of Earths circumference is the most famous among the results obtained by Eratosthenes, who estimated that the meridian has a length of 252,000 stadia, with an error on the real value of less than two percent. Eratosthenes described his arc measurement technique, in a book entitled On the measure of the Earth.

Hipparchus of Nicaea, 190120 BC, yet another ancient Greek astronomer, erected an early observatory on the island of Rhodes around 150 BC, and set about compiling a star catalogue with approximately 850 entries. He calculated the celestial coordinates for each star using the first known trigonometric table, and developed and improved several astronomical instruments, including the astrolabe.

Dedicated to Hipparchus contribution to the early study of the solar system, a crater on the surface of Mars, was named after him in 1973. A larger crater on the moon was also named after the ancient Greek astronomer.

The Antikythera Mechanism,often referred to as the worlds first computer, was discovered inside an ancient shipwreck by Greek sponge divers on May 17, 1901. After numerous studies, it was estimated to have been constructed between 150 BC and 100 BC.A later study places it at 205 BC,just seven years after the death of Archimedes.

The worlds oldest surviving mechanical calculator, it was used by ancient Greek astronomers. The device has now been somewhat deteriorated by the passage of time, but when intact it would have appeared as a box, housing dozens of finely machined bronze gear wheels.

When manually rotated by a handle, the gears spun dials on the exterior showing the phases of the moon, the timing of lunar eclipses, and the positions of the five planets then known (Mercury, Venus, Mars, Jupiter, and Saturn) at different times of the year. This even accounted for their retrograde motion an illusionary change in the movement of planets through the sky.

It may even have been the work of Archimedes himself, but there is no documentation of that, only speculation. Gearing technology with the sophistication of the Antikythera Mechanism was not seen again for one thousand years.

The ancient calculator also includes an astrological calendar, as the indicators seem to revolve around the zodiac, revealing the movements of both the moon and the planets.

The National Observatory is the contemporary location for a journey to the stars. As noted above, the Asteroskopeio is within close proximity to the physical space used by ancient Greek astronomers who contributed so much to what we know of the universe today.

Ancient Greek astronomers such as Metonas, Pythagoras, Philolaus, Eratosthenes, Ptolemy, Aristarchus, Hipparchus, Archimedes developed the theories of calculation of the size, the time and the distance of planets within the human solar system. These contributions were the building blocks that made journeys off earth possible today.

Progress was marked by enlightened and renowned scientists in Greece who paved the way to knowledge with the creation of the Asteroskopeio in the 1800s. Thanks to the National Observatory, visitors to Athens can travel to the stars even if they are not Richard Branson or Jeff Bezos.

The tycoon Branson said, After more than 16 years of research, engineering, and testing, Virgin Galactic stands at the vanguard of a new commercial space industry, which is set to open space to humankind and change the world for good.

Lets hope he remembers to thank all those ancient Greek astronomers and not just the people who work for Virgin Galactic.

How Ancient Greeks Set Humanity on the Path to Space Exploration - Greek Reporter

Vanessa Wyche will take the reins at Johnson Space Center while Janet Petro will lead Kennedy Space Center as they prepare for the Artemis 1 launch to the moon.

HOUSTON NASA Administrator Bill Nelson has promoted two women as directors of Johnson Space Center in Houston and Kennedy Space Center in Florida.

Vanessa Wyche will take the reins at JSCand Janet Petro will lead KSC as they prepare for theArtemis 1 launch to the moon scheduled for later this year.

Both Vanessa and Janet are exceptional leaders who will help propel NASA forward as we venture farther out into the cosmos than ever before, said Nelson. Its an incredible time at NASA, and with Vanessa and Janet leading the Johnson and Kennedy Space Centers, NASA will embark on a new era of space exploration starting with the Artemis I launch to the Moon later this year.

Before being named acting director on May 3, Wyche had served as deputy director of JSC since August 2018. Before that, the 31-year NASA veteran held a number of roles, including flight manager for multiple space shuttle missions.

Vanessa is a tenacious leader who has broken down barriers throughout her career, said NASA Deputy Administrator Pam Melroy. Vanessas more than three decades at NASA and program experience in almost all of the human spaceflight programs at Johnson is an incredible asset to the agency. In the years to come, Im confident that Houston will continue to lead the way in human spaceflight.

Wyche said she is humbled and honored to be chosen to lead more than 10,000 employees at JSC as they push ahead to the moon and beyond.

As the home to Americas astronaut corps, International Space Station mission operations, the Orion and Gateway programs, and a host of future space developments, Johnson is a world leader in human space exploration and is playing a key role in the next giant leaps in American excellence in space," Wyche said in a statement.

Prior to being named Kennedys acting director, Petro served as the centers deputy director since 2007.

She will oversee the centers world class multi-user spaceport, supporting both commercial customers and NASAs science and human exploration missions.

"She was central to Kennedys transition to a multi-user spaceport, bringing a variety of new commercial and government partners to Kennedy," NASA said in a statement. "She led cross-agency initiatives with the Federal Aviation Administration and U.S. Air Force to streamline government processes and support commercial space operations, increase government efficiency, and limit redundancy."

Petro grew up on Florida's Space Coast and said she's the second generation in her family to work at KSC.

"Its truly exciting to help grow the multi-user spaceport as we prepare for Artemis and continue launching commercial crew missions to the International Space Station," she said.

Petro began her professional career as a commissioned officer in the U.S. Army and graduated from the U.S. Military Academy at West Point in 1981.

NASA names two women to lead JSC and KSC during 'new era of space exploration' - KHOU.com

In 2009, using NASAs Interstellar Boundary Explorer, also known as IBEX, astronomers spied a strange ribbon-like structure dancing between our solar system and the rest of interstellar space.

The discovery of the IBEX Ribbon, which is invisible to both telescopes and the human eye, was one of scientists first forays into understanding more about our heliospherea bubble-like shield made up of solar winds.

A new study published in the Astrophysical Journal maps the entire boundary of this shield, and the data collected may be used to usher in a new era of heliophysics exploration.

Most instruments that detect particles in space are detecting charged particles, says Daniel Reisenfeld, a senior scientist at Los Alamos National Laboratory in New Mexico and lead author of the study. But IBEX is unique.

It detects energetic neutral atoms, or ENAsions that originally come off the sun but collide with interstellar electrons, neutralizing them. These atoms can be found everywhere in space, and observing ENA fluxes across time can be a powerful imaging tool.

So what exactly was that mysterious ribbon? Scientists have since determined that what they were seeing was a giant swath of ENAs lighting up the night sky.

Using data IBEX collected on ENAs as it charted just one 11-year solar cycle, the time between shifts in the suns magnetic field, researchers built a three-dimensional map of the entire heliosphere, which Reisenfeld says shields Earth and other planets from harmful radiation.

Our Earth gets bombarded by cosmic rays, galactic cosmic rays all the time, he says. These rays can subtly affect airplanes that fly near the poles, often on trips between Europe or Asia and the US.

Scientists say that to study other planets astrospheres, which is what heliospheres are called when they surround other stars, we must first understand our own.

A lot of physical models which are being developed right now are based on the discoveries of the IBEX mission, says Nikolai Pogorelov, a professor of space science at the University of Alabama in Huntsville. Its not only experimental, he says, adding that it will be used for [a] real purpose.

You may need things for life support. Life support is not so much of a driver for this because were increasingly moving towards very efficient life support systems and the cost of resupply compared with, for example, propellent in terms of the total mass taken to a place is quite small. Oxygen, for example, is used in propellant and life-support, so theres a synergy between these things. You can also use local materials to create structures or radiation shielding, thermal shielding or a landing pad, for example.

At ESA, we look at what can be created locally and how this can be done. The most obvious example is to harvest water and from this, create hydrogen and oxygen, which are useful and are rocket fuel. We find water ice at the poles of the Moon. We also find it on Mars. This could be universally applicable around the Solar System by water.

We also look at how to extract useful things from the rocks and minerals found. The surface of the Moon is covered in ground-up powder, powdered rock, Regolith, generated by billions of years of impact onto the surface. This relic, like all minerals, is made up of oxygen combined chemically with different metals. We look at processes taken from terrestrial industries and use those to learn how to take oxygen out of lunar materials, which leaves us with oxygen and metal alloys that can be used to do a 3D print to create materials in the future. Oxygen extraction is something were getting pretty good at; however, metal production is something that will happen in the future to make decent quality alloys.

The Package for Resource Observation and in-Situ Prospecting for Exploration, Commercial exploitation and Transportation (PROSPECT) assesses and accesses potential resources on the Moon and aims to prepare technologies that could be used, in the future, to extract these resources. This will drill beneath the surface at the lunar poles. It will extract water ice, then analyse the chemistry of that to help us work out the abundance, distribution, origins, how that water evolves in the poles and how it might be used responsibly in the future.

A key thing to understand is how to use local materials, where are the opportunities and what will it take to use them? How can we do that responsibly? How can we work in the most efficient way possible using the materials that we have, using recycled, for example? Also, how can local materials be used, extracted and processed to respect the environment? The idea is that there are related lessons to bring back to Earth.

Building vehicles to get into space is expensive, theyre extremely complex and must work. Failure is not an option if people are sitting on the top of a rocket or youve got a billion or multi-billion-euro spacecraft. This sits on tonnes of highly explosive material to explode. Doing this in a controlled and careful way that delivers what you need in the way you need, is complex and dangerous. The development of vehicles, new buildings and rocket engines are costly undertakings.

We now see a drive towards reusability, of course, SpaceX has driven that conceptually and in Europe, were looking at reusable concepts. Thats one way of bringing down the cost of access, so globally, we see the cost of getting to space reducing. As that happens, we see more and more people using and accessing space. Space will become an increasing part of our economic sphere, and its already an integral part of many aspects of our lives. That utilisation of space will expand over the coming years. In exploration, we endeavour to take humanitys next economic sphere and expand that beyond our near-Earth environments, outwards into the Solar System. In the long-term, that will have enormous benefits for humanity.

Los Angeles, California--(Newsfile Corp. - July 6, 2021) - SGE which stands for Society of Galactic Exploration is an Ethereum based token developed to celebrate and encourage space exploration amongst the masses. Roger Malcolm III, "SGE is built to bridge the gap between space exploration and the general public." This cryptocurrency will offer investors the golden opportunity to be part of the developmental process of the telescope.

Roger, a college student pursuing mechanical engineering and the founder and developer of SGE, introduced coins to celebrate space exploration. The company operates with a team of 24 young enthusiasts keen on thinking out of the box to bridge the gap between space exploration and cryptocurrency in the form of SGE tokens.

The advantage of SGE tokens is that it is a utility coin and is not for financial gains. Investors who wish to see the world above can invest in a hiss. The developer and their team will be transparent with their official names released. This is relatively uncommon in the world of cryptocurrency. Through this platform, holders will be able to control a telescope from the palm of their hands. Their mobile application will feature a remote login option to various telescopes revolving above us so that users can witness the world above.

SGE, per a legal opinion, is recorded as a utility coin. Instead, the purpose is to hold cash utilized as a currency to buy time for the telescope application. The developers said that "SGE has started performing audits of themes with an appealing format so other coins can post them immediately after receiving them." It will also perform audits promptly, which can be rare, they added. In case any currencies fail the initial audit, developers will provide consultation to change such contracts.

The company is also looking forward to launching hardware that will act as a wallet into space and will contain at least 1 SGE token for every humanoid on Earth. Not just that, SGE announced that they are keen to allow investors to control telescopes from their mobile app. They will enable users to take beautiful pictures of the vast emptiness above us, explore galaxies for beauty, and know the unknown. After which, users will also be able to sell their pictures in the form of NFTs.

NFT means a non-fungible token, in essence to a collectible digital asset that holds value as a form of cryptocurrency and as a form of art or culture. Unlike Bitcoins, NFT is unique and can't be exchanged. However, they store extra data and information that elevates it above pure currency. The types of NFTs are varied and can be seen in digital art or a music file, anything unique that could be stored digitally and thought of to hold value. NFTs are like a collector's item, but instead of physical and touchable stuff, it is available in the form of a JPG file.

This mobile application will allow users to control a mighty telescope straight from their mobile screen. SGE has long announced a partnership with the Down Under Observatory in Colorado, backed by NASA-affiliated astrophotographer Terry Hancock. SGE will be the first cryptocurrency to be in space and will also be sponsoring an area Concordia in the base 11 Space Challenge. SGE will have their logo added to their rocket and send a hardware wallet with SGE tokens to space.

Since SGE is a fast-growing, deflationary token with a strong community, it decided to focus on Space Exploration. SGE also developed its own NFT platform recently. Users who want to experience their services or invest in SGE can do that through their official website.
