Intuitive Machines’ Odysseus Spacecraft Lands on Moon Carrying 6 NASA Payloads – Executive Gov

An Intuitive Machines-built lunar lander carrying six NASA science research and technology demonstrations has touched down on the lunar surface following a seven-day journey to lunar orbit.

NASA said Friday its Navigation Doppler Lidar for Precise Velocity and Range Sensing guidance system for descent and landing has helped Intuitive Machines Nova-C lander, called Odysseus, softly land Thursday near Malapert A, a landing site close to the moons South Pole region.

According to NASA, Intuitive Machines turned to the guidance system when it encountered a sensor issue with its navigation system.

The NASA instrument uses a laser that emits pulses through three optical telescopes and measures speed, direction and altitude during descent and touchdown.

Other NASA payloads launched onboard Odysseus are a CubeSat-sized autonomous navigation demonstrator, a laser retroreflector array, a radio frequency mass gauge, a photoelectron sheath density observation instrument and stereo cameras for lunar plume-surface studies.

This feat from Intuitive Machines, SpaceX, and NASA demonstrates the promise of American leadership in space and the power of commercial partnerships under NASAs CLPS initiative. Further, this success opens the door for new voyages under Artemis to send astronauts to the Moon, then onward to Mars, said NASA Administrator Bill Nelson.

Artemis II Crew, Recovery Teams Train for Final Phase of Moon Mission – NASA

NASA astronaut and Artemis II pilot Victor Glover is assisted by U.S. Navy personnel as he exits a mockup of the Orion spacecraft in the Pacific Ocean during training Feb. 25, while his crewmates look on. The Artemis II crew and a team from NASA and the Department of Defense are spending several days at sea to test the procedures and tools that will be used to help the crew to safety when they splash down in the ocean at the end of their 10-day, 685,000-mile journey around the Moon next year as part of the first crewed mission under NASAs Artemis campaign.

On the day of the crews return to Earth, a Navy ship with specially trained personnel will await splashdown and then approach the Orion capsule to help extract the four astronauts. An inflatable raft, called the front porch, will provide a place for them to rest when they exit the capsule before they are then individually hoisted by helicopters and flown to the waiting ship.

Artemis II, launching atop the SLS (Space Launch System) rocket from NASAs Kennedy Space Center in Florida, will test the Orion spacecrafts life support systems needed for future lunar missions.

DOD, GSA & NASA Release Interim Rule on SDVOSB Certification – Executive Gov

The Department of Defense, NASA and the General Services Administration have issued an interim rule to implement the final rules by the Small Business Administration with regard to the certification of service-disabled veteran-owned small businesses.

The provisional rule was introduced as an amendment to the Federal Acquisition Regulation to implement sections of the National Defense Authorization Act for fiscal years 2021 and 2022, according to a Federal Register notice published Friday.

Section 862 of FY 2021 NDAA moves the verification of SDVOSBs from the Department of Veterans Affairs to SBA and establishes a certification requirement for such businesses seeking set-aside and sole-source awards under the SDVOSB program within the federal government.

Meanwhile, section 863 of FY 2022 NDAA requires that a small business determined ineligible by SBA for SDVOSB certification to update its status in the System for Award Management within two days of the eligibility determination.

The interim rule intends to implement SBAs governmentwide certification program for SDVOSBs and update protest procedures for such business concerns.

Interested stakeholders have until April 23 to submit comments that will help inform the final rule.

SpaceX, NASA ‘go’ to launch Crew-8 astronaut mission to ISS on March 1 – Space.com

SpaceX and NASA are officially go to launch their next astronaut mission to International Space Station (ISS) this week, with its four-person crew arriving at their Florida launch site on Sunday (Feb. 25).

Called Crew-8, the upcoming SpaceX mission will launch four astronauts into orbit on the Dragon capsule Endeavour and Falcon 9 rocket from Pad 39A of NASA's Kennedy Space Center in Cape Canaveral. Liftoff is scheduled for March 1 at 12:04 a.m. EST (0504 GMT).

Related: 8 ways SpaceX has transformed spaceflight

"Even though we all go today, we're constantly paying attention to what the rocket and spacecraft are telling us so that we'll make sure that we launch when the crew and the spacecraft are ready to go, and we're ready to have a good flight to the station and a good return," Ken Bowersox, NASA's associate administrator for space operations and a former astronaut, told reporters in a Sunday night teleconference.

SpaceX's Crew-8 mission for NASA will launch NASA astronauts Matthew Dominick, Michael Barrett, Jeannette Epps and Russian cosmonaut Alexander Grebenkin on a six-month expedition to the ISS. They will relieve their Crew-7 predecessors, another four-astronaut team, who will return to Earth on a SpaceX Dragon a week after Crew-8 reaches the ISS.

Dominick will command the Crew-8 flight to the ISS with Barrett as pilot. Epps and Grekenkin are mission specialists. The mission is the first career spaceflight for all but Barrett on the Crew-8 team. NASA and SpaceX initially aimed to launch Crew-8 to the ISS on Feb. 22, but delayed it to March 1 to clear a path for a private moon launch on a SpaceX Falcon 9 from their same launch pad on Feb. 15.

The Crew-8 astronauts arrived at the Kennedy Space Center on Sunday afternoon as they spend their final days on Earth ahead of launch. The quartet will perform a dress rehearsal for their launch overnight on Monday and Tuesday, with SpaceX expected to perform a so-called "hot-fire" test of the Falcon 9's first stage engines a day later.

Steve Stitch, NASA's Commercial Crew Program manager, told reporters Sunday that NASA and SpaceX are working through some final issues to clear ahead of the Crew-8 launch. Those include reviews of composite material fasteners on the Dragon/Falcon 9 launch vehicle for Crew-8 that are expected to be resolved before flight. Engineers are also reviewing some paint discoloration on Crew-7's Dragon capsule currently docked at the ISS, apparently due to residue tape on the capsule, to ensure it's not an issue for reentry and landing.

Crew-8 will mark the fifth flight of the Crew Dragon capsule Endeavour, which first flew astronauts to the ISS in May 2020 on SpaceX's first-ever human spaceflight, Demo-2. SpaceX and NASA are currently working to certify the reusable Dragon capsules for up to 15 spaceflights, NASA officials said.

SpaceX is one of two commercial companies with multi-billion-dollar contracts to fly astronauts to and from the ISS for NASA. The other company, Boeing, aims to launch the first crewed flight on its Starliner spacecraft no earlier than April 22.

A Nasa mission that collided with an asteroid didn’t just leave a dent it reshaped the space rock – theconversation.com

A frequent idea in sci-fi and apocalyptic films is that of an asteroid striking Earth and causing global devastation. While the probabilities of this kind of mass extinction occurring on our planet are incredibly small, they are not zero.

The results of Nasas Dart mission to the asteroid Dimorphos have now been published. They contain fascinating details about the composition of this asteroid and whether we can defend Earth against incoming space rocks.

The Double Asteroid Redirection Test (Dart) was a spacecraft mission that launched in November 2021. It was sent to an asteroid called Dimorphos and commanded to collide with it, head on, in September 2022.

Dimorphos posed and poses no threat to Earth in the near future. But the mission was designed to see if deflecting an asteroid away from a collision course with Earth was possible through kinetic means in other words, a direct impact of a human-made object on its surface.

Asteroid missions are never easy. The relatively small size of these objects (compared to planets and moons) means there is no appreciable gravity to enable spacecraft to land and collect a sample.

Space agencies have launched a number of spacecraft to asteroids in recent times. For example, the Japanese space agencys (Jaxa) Hayabusa-2 mission reached the asteroid Ryugu in 2018, the same year Nasas Osiris-Rex mission rendezvoused with the asteroid Bennu.

The Japanese Hayabusa missions (1 and 2) fired a small projectile at the surface as they approached it. They would then collect the debris as it flew by.

However, the Dart mission was special in that it was not sent to deliver samples of asteroid material to labs on Earth. Instead, it was to fly at high speed into the space rock and be destroyed in the process.

A high-speed collision with an asteroid needs incredible precision. Darts target of Dimorphos was actually part of a double asteroid system, known as a binary because the smaller object orbits the larger one. This binary contained both Didymus the larger of the two objects and Dimorphos, which behaves effectively as a moon.

The simulations of what has happened to Dimorphos show that while we might expect to see a very large crater on the asteroid from Darts impact, it is more likely that it has, in fact, changed the shape of the asteroid instead.

The collision was of a mass of 580kg hitting an asteroid of roughly 5 billion kg. For comparison, this is equivalent to an ant hitting two buses. But the spacecraft is also travelling around 6 kilometres per second.

The simulation results based on observations of the asteroid Dimorphos have shown that the asteroid now orbits around its larger companion, Didymus, 33 minutes slower than before. Its orbit has gone from 11 hours, 55 minutes to 11 hours, 22 minutes.

The momentum change to the core of Dimorphos is also higher than one would predict from the direct impact, which may seem impossible at first. However, the asteroid is quite weakly constructed, consisting of loose rubble held together by gravity. The impact caused a lot of material to be blown off of Dimorphos.

This material is now travelling in the opposite direction to the impact. This acts like a recoil, slowing down the asteroid.

Observations of all the highly reflective material that has been shed from Dimorphos allows scientists to estimate how much of it has been lost from the asteroid. Their result is roughly 20 million kilograms equivalent to about six of the Apollo-era Saturn V rockets fully loaded with fuel.

Combining all the parameters together (mass, speed, angle and amount of material lost) and simulating the impact has allowed the researchers to be fairly confident about the answer. Confident not only regarding the grain size of the material coming from Dimorphos, but also that the asteroid has limited cohesion and the surface must be constantly altered, or reshaped, by minor impacts.

But what does this tell us about protecting ourselves from an asteroid impact? Significant recent impacts on Earth have included the meteor which broke up in the sky over the city of Chelyabinsk, Russia, in 2013, and the infamous Tunguska impact over a remote part of Siberia in 1908.

While these were not the kinds of events that are able to cause mass extinctions like the 10km object that wiped out the dinosaurs when it struck our planet 66 million years ago the potential for damage and loss of life with smaller objects such as those at Chelyabinsk and Tunguska is very high.

The Dart mission cost US$324 million (255 million), which is low for a space mission, and with its development phase completed, a similar mission to go and deflect an asteroid heading our way could be launched more cheaply.

The big variable here is how much warning we will have, because a change in orbit of 30 minutes as was observed when Dart struck Dimorphos will make little difference if the asteroid is already very close to Earth. However, if we can predict the object path from further out preferably outside the Solar System and make small changes, this could be enough to divert the path of an asteroid away from our planet.

We can expect to see more of these missions in the future, not only because of interest in the science surrounding asteroids, but because the ease of removing material from them means that private companies might want to step up their ideas of mining these space rocks for precious metals.

NASA Seeks Volunteers for Second Mars Simulation Mission but There Are a Few Constraints – PEOPLE

NASA is searching for a second round of volunteers to take part in a project aimed at discovering what it will be like to live on Mars.

Earlier this month, the space company announced in a release that it is seeking more participants who would be willing to live on a fake version of Mars at NASA's Johnson Space Center in Houston, Texas, for one year, ahead of human exploration of the actual planet in the future.

Marking the second of three missions calledCHAPEA a.k.a. Crew Health and Performance Exploration Analog the latest will see four volunteers living in a 1,700-square-foot simulation, called theMars Dune Alpha, which is a 3D-printed habitat featuring living quarters for each volunteer, a workspace, a medical station and lounge areas, as well as a galley and food growing stations.

The man-made area, NASA said, "simulates the challenges of a mission on Mars, including resource limitations, equipment failures, communication delays and other environmental stressors."

Crews will also be responsible for various tasks during their time in the habitat, the organization added, including "simulated spacewalks, robotic operations, habitat maintenance, exercise and crop growth."

In order to participate in the simulation, which will close applications on April 2 and later take place in 2025, NASA said volunteers "should have a strong desire for unique, rewarding adventures and interest in contributing to NASAs work to prepare for the first human journey to Mars."

These volunteers, the space company continued, must be between 30 and 55 years old, non-smokers and speak English "for effective communication between crewmates and mission control."

"Crew selection will follow additional standard NASA criteria for astronaut candidate applicants," the organization added, also noting that a masters degree in engineering, math, biology or other sciences is necessary, as is professional experience or at least two years of doctoral work in the areas or a test pilot program.

Volunteers who can be compensated for the mission can also qualify if they have 1,000 hours of piloting experience, as well as if they have military experience or a bachelor's degree in a STEM field with four years of professional experience, NASA said.

Though no human has ever traveled to Mars, NASA has sentseveral devices and rovers to fly by and explore the planet over the years.

Currently, a first CHAPEA crew is taking part in a mission at the Houston-based habitat. They are more than halfway through their mission, NASA said.

In the near future, NASA plans to take part in a similar mission, called Artemis, to learn about the moon in an effort to eventually send the first woman, person of color and international partner astronaut there.

"As NASA works to establish a long-term presence for scientific discovery and exploration on the moon through the Artemis campaign, CHAPEA missions provide important scientific data to validate systems and develop solutions for future missions to the Red Planet," the organization said in a statement.

"With thefirst CHAPEA crewmore than halfway through their yearlong mission, NASA is using research gained through the simulated missions to help inform crew health and performance support during Mars expeditions," NASA continued.

Set against a bright, blue Florida skyline, the three astronauts and one cosmonaut who make up the SpaceX Crew-8 mission touched down at NASAs Kennedy Space Center Sunday afternoon.

The crews Gulfstream cruised in for a landing at the Space Florida Launch and Landing Facility at about 1:45 p.m. (1845 UTC). They were greeted on the tarmac by, Jennifer Kunz, a KSC Associate Director, and Dana Hutcherson, Deputy Director Commercial Crew.

Coming out here to the Cape, every time, Im a kid in a candy store, said Matthew Dominick, a NASA astronaut and the commander of the Crew-8 mission.

While the upcoming mission will be the first spaceflight for Dominick, he worked for NASA for seven years leading up this launch.

Its an incredible time to be involved in spaceflight. Who wouldve though five or six years ago that this would be the fifth flight of Endeavour that we get to go on? Who wouldve though five or six years ago that the competition for launch or the constraint to launch would be a launch pad? Dominick said, referring to the recent launch of the IM-1 robotic mission to the Moon. We delayed our launch a few days because theres stiff competition to get out there to 39A. Its not a rocket constraint, its a pad constraint.

Hes leading a trio that include two additional NASA astronauts, Michael Barratt and Jeanette Epps, and Roscosmos cosmonaut, Alexander Grebenkin. They will launch to the orbiting outpost no earlier than Friday, March 1 at 12:04 a.m. EST (0504 UTC).

Barratt is returning to launch at KSC for the first time since his final flight as a member of STS-133 in 2011. He said its remarkable to be back now in the era of the Commercial Crew Program and be preparing to launch atop a SpaceX Falcon 9 rocket and inside a Crew Dragon spacecraft.

The fact that this spaceport is so busy, so vibrant is just an amazing thing, Barratt said. Its just an absolute pleasure to see Kennedy Space Center being the thriving spaceport that it is. Were very honored to be a part of that. I cannot wait to get back to that magnificent station, I cant wait to fly this new spaceship and I cant wait to to fly with this crew.

Like Dominick and Grebenkin, Epps will be making her first trip to space on this mission. Shes experienced pivots from flying on a Russian Soyuz to then Boeing Starliner and finally to her current assignment on Crew-8.

Its overwhelming to me how many people contributed to this. So, I just want to thank everyone whos been involved, Epps said. Im very grateful for this flight. Ive trained for Soyuz, Ive trained for Boeing, Ive trained for a lot of vehicles, but Im honored to fly with this crew on the Dragon Endeavour.

Endeavor will be making its 5th flight into space on this mission, marking its position as the flight leader in the SpaceX spacecraft fleet. Five missions is the most that NASA has certified a Dragon to fly to date.

A new Dragon spacecraft is expected to enter the fleet sometime in 2024.

Nusantara: A New Capital City in the Forest – nasa.gov

Since the summer of 2022, the jungles of eastern Borneo have undergone rapid change. Roads have been carved into the landscape and buildings erected near Balikpapan Bay in Eastern Kalimantan, as Indonesia builds a new capital city.

According to government officials, development of the new capital on the island of Borneo was motivated in large part by the myriad of environmental challenges faced by Jakarta, Indonesias current capital. The citys metropolitan area is home to 30 million people and has expanded considerably in recent decades. Frequent flooding, heavy traffic, hazardous air pollution, and drinking water shortages are common occurrences. Jakarta is also quickly sinking. Excessive groundwater withdrawals have contributed to subsidence rates of up to 15 centimeters (6 inches) per year, and 40 percent of the city is now below sea level.

In 2019, Indonesias president announced that the administrative center of the country would be moving from the populous island of Java to the sparsely populated island of Borneo. Construction on the new capital city, called Nusantaraan old Javanese term meaning outer islands or archipelagobegan in July 2022 in an area of forests and oil palm plantations 30 kilometers (19 miles) inland from the Makassar Strait.

The images above show the site of Nusantara in April 2022 (left) and in February 2024 (right). They were captured by the OLI-2 (Operational Land Imager-2) on Landsat 9 and the OLI on Landsat 8, respectively. In the 2024 image, soil has been exposed for a network of roads carved into the forest. The initial stage of development involves constructing government facilities and other buildings for the expected initial population of 500,000 people, according to the project website.

Project plans stipulate that it will be a green, walkable metropolis, powered with renewable energy, with 75 percent of the city remaining forested. But some researchers worry this land use change could harm the forests and wildlife in the region. The stretch of land and coastal waters being developed are rich in biodiversity and home to mangroves, proboscis monkeys, and Irrawaddy dolphins.

Although the site has changed substantially over the past year and a half, the city is far from being finished. Construction is planned to be completed by 2045.

Ascent Solar Technologies to fly space solar modules on NASA’s upcoming LISA-T mission SatNews – SatNews

Ascent Solar Technologies (Nasdaq: ASTI) has announced that the Companys solar module products will fly on NASAs upcoming Lightweight Integrated Solar Array and AnTenna (LISA-T) mission, scheduled for launch this summer.

The mission, led by NASAs Space Technology Mission Directorate and the agencys Marshall Space Flight Center in Huntsville, will demonstrate the capability to deploy large-area arrays on lightweight, low-cost and small spacecraft.

LISA-T is the fourth mission in NASAs Pathfinder Technology Demonstrator (PTD) series of missions evaluating novel, small spacecraft capabilities on orbit. Managed by NASAs Ames Research Center in Silicon Valley, these demonstration missions facilitate the direct infusion of new technologies into the agencys future science and exploration missions.

LISA-T (PTD-4)s solar arrays are lower mass and stowed volume, and produce three times more power than alternative PV solutions traded within the system envelope. PTD-4s deployable solar arrays are designed to scale larger than the missions CubeSat form factor with options capable of generating kilowatts of power to small spacecraft.

Leading up to this spacecraft demonstration, Ascents PV products were previously evaluated on the International Space Station. Modules tested on NASAs MISSE-X experiment validated the resilience of the companys CIGS material in the space environment, both bare and encapsulated. Additional Ascent modules with lower-cost and lighter-weight laminates are being evaluated on the upcoming MISSE payload slated to fly on SpaceXs 30th Commercial Resupply Mission to the space station scheduled for March.

Selection for this upcoming space mission is the culmination of years of Ascents work with NASA to optimize the PV modules that enabled LISA-Ts ambitious spacecraft mass and power budgets to close, said Paul Warley, CEO of Ascent Solar Technologies. This mission will demonstrate that previously unachievable spacecraft requirements can in fact be met. It also provides a shining example of the benefits of public-private partnerships that leverage new and innovative commercial technologies, as NASA programs like MISSE & PTD lead the way for even more capable spacecraft for government and commercial space missions. The modules developed for LISA-T informed the design of Ascents Titan line of space products, facilitating further maximization of power generation to the extent that spacecraft can produce kilowatts per kilogram of array in the space environment with minimal degradation over the life of the mission.

Why the Odysseus Moon Landing Is So Important – TIME

Early this week, Facebook provided me with a sweet piece of serendipity when it served up a picture of the late Gene Cernan. I had taken and posted the picture in 2014, when Cernan, the last man on the moon, was being feted at the premiere of the documentary about his life, titled, straightforwardly, The Last Man On the Moon. I had gotten to know Gene well over the course of many years of reporting on the space program, and was keenly saddened when we lost him to cancer three years later.

But this week, on Feb. 22, Cernan made news in a bank-shot sort of way, when the Odysseus spacecraft touched down near the south lunar pole, marking the first time the U.S. had soft-landed metal on the moon since Cernan feathered his lunar module Challenger down to the surface of the Taurus-Littrow Valley on Dec. 11, 1972. The networks made much of that 52-year gulf in cosmic history, but Odysseus was significant for two other, more substantive reasons: it marked the first time a spacecraft built by a private company, not by a governmental space program, had managed a lunar landing, and it was the first time any ship had visited a spot so far in the moons south, down in a region where ice is preserved in permanently shadowed craters. Those deposits could be harvested to serve as drinking water, breathable oxygen, and even rocket fuel by future lunar astronauts.

Today, for the first time in more than a half century, the U.S. has returned to the moon, said NASA Administrator Bill Nelson in a livestream that accompanied the landing. Today, for the first time in the history of humanity, a commercial company and an American company launched and led the voyage up there.

Nelsons enthusiasm was not misplaced. The six Apollo lunar landings might have been epochal events, but they were also abbreviated ones. The longest stay any of the crews logged on the surface was just three days by Cernan and his lunar module pilot Harrison Schmitt. The shortest stay was less than 21 hours, by Neil Armstrong and Buzz Aldrin during the Apollo 11 mission, the first lunar landing, in 1969. That so-called flags and footprints model was fine for the days when the U.S. lunar program was mostly about doing some basic spelunking and, not for nothing, beating the much-feared Soviet Union at planting a flag in the lunar regolith.

But the 21st-century moon program is different. Ever since NASA established its Artemis program in 2017, the space agency has made it clear that the new era of exploration will be much more ambitious. The goal is in part for American astronauts to establish at least a semi-permanent presence on the moon, with a mini-space station known as Gateway positioned in lunar orbit, allowing crews to shuttle to and from the surface. NASA also plans to create a south pole habitat that the crews could call home. And all of this will be done by a much more diverse corps of astronauts, with women and persons of color joining the all-white, all-male list of astronauts who traveled to the moon the first time around.

There is, however, a catch: money. In the glory days of Apollo, NASA funding represented 4% of the total federal budget; now its just 0.4%. That means taking the job of designing and building spacecraft off of the space agencys plate and outsourcing it to private industry, the way SpaceX now ferries crews to the International Space Station, charging NASA for the rides the way it charges satellite manufacturers and other private customers. The Commercial Crew Program, of which SpaceX is a part, was established in 2011, and has been a rousing success, so much so that, in 2018, NASA took things a step further, announcing the Commercial Lunar Payload Services (CLPS) program, similarly outsourcing the delivery of equipment that astronaut-settlers will need.

CLPS, however, stumbled out of the gate. On Jan. 8 of this year, the Peregrine lander, built by Pittsburgh-based Astrobotic Technology, was launched to a similar lunar region that Odysseus targeted, carrying 20 payloads, including mini-rovers, a spectrometer designed to scour the soil for traces of water, and another to study the moons exceedingly tenuous atmosphere. Peregrine was not destined to make it out of Earths orbit, however, after an engine failure stranded itleaving the ship to plunge back into the atmosphere 10 days after launch.

There will be some failures, Astrobotic CEO John Thornton told TIME before the Peregrine mission launched. But if even half of these missions succeed, it is still a wild, runaway success.

Odysseus landed in that second, happier column. Built by Houston-based Intuitive Machines, the spacecraft carries six science instruments, including stereoscopic cameras, an autonomous navigation system, and a radio wave detector to help measure charged particles above the surfacecritical to determining the necessary sheathing in an eventual habitat. NASA has at least eight other CLPS missions planned, including two more by Intuitive Machines and another by Astrobotic, through 2026. After that, the program is expected to go on indefinitelysupplying lunar bases for as long as Artemis has astronauts on the moon.

Just when those explorers will arrive is unclear. The Artemis II mission, which was expected to take astronauts on a circumlunar journey in November of this year, has been postponed until September of 2025, due to R&D issues in both the Space Launch System moon rocket and the Orion spacecraft. Artemis III, set to be the first landing since the Apollo 17 astronauts trod the regolith, will likely not come until 2026 at the earliest.

That 52 year wait would not have sat well with that long-ago crew. In the same year in which they flew, the National Football Leagues Miami Dolphins made a less consequential history of their own, when they became the first and so far only team to go through an entire season undefeated. The surviving members of that legendary squad have waited out the seasons that have followed, pulling for their record to standand conceding relief when the final undefeated team at last records a loss. Cernan, for his part, wanted nothing to do with his own last man record. We leave here as we came and, God willing, we shall return, with peace and hope for all mankind, he said before he climbed back up the ladder of his lunar module and left the moon behind. The success of Odysseus does not make the fulfillment of Cernans wish imminent, but it does nudge it closer.

Why the Odysseus Moon Landing Is So Important - TIME

Ingenuity Mars helicopter snapped rotor blade during hard landing last month (video, photo) – Space.com

There's no way Ingenuity could fly through this.

Ingenuity, the 4-pound (1.8 kilograms) helicopter that journeyed to Mars with NASA's Perseverance rover, was grounded for good after suffering a hard landing during a Jan. 18 flight.

New observations by Perseverance show just how rough that touchdown was and make it easy to understand why Ingenuity is now a frozen feature of the Martian landscape.

Related: NASA to 'wiggle' broken Ingenuity Mars helicopter's blades to analyze damage

We already knew that the Jan. 18 landing broke off the tip of at least one of Ingenuity's four rotors; a selfie snapped by the little chopper shortly thereafter made that plain.

That damage by itself was enough to end Ingenuity's flying days on Mars, mission team members said at the time. Helicopters must be perfectly balanced to maintain controlled flight, and losing bits of a rotor robbed Ingenuity of that balance.

But the drone lost more than just a rotor tip. The new Perseverance photos, which the rover took with its SuperCam remote imager on Sunday (Feb. 25), show that at least one of Ingenuity's four rotor blades snapped clean off on Jan. 18.

Ingenuity and Perseverance landed together on the floor of Mars' Jezero Crater in February 2021. Two months later, the rotorcraft deployed from the rover's belly and began its prime mission, a five-flight campaign designed to show that powered flight is possible on Mars despite the planet's thin atmosphere.

Ingenuity aced that campaign, then shifted to an extended mission during which it served as a scout for the life-hunting, sample-collecting Perseverance. The helicopter racked up a whopping 67 sorties during this phase of its Mars operations, which were led (like those of Perseverance) by NASA's Jet Propulsion Laboratory (JPL) in Southern California.

Its final flight occurred over a sandy patch of terrain that lacked prominent rocks and other features that Ingenuity relied on for navigation, mission team members said. Ingenuity could not stick the landing, and its fast-spinning blades hit the ground.

The helicopter's legacy is assured. Ingenuity was the first vehicle ever to achieve powered flight in the skies of a world beyond Earth, and its success will pave the way for other aerial explorers.

"The NASA JPL team didn't just demonstrate the technology," Tiffany Morgan, deputy director of NASA's Mars Exploration Program, said during a Jan. 31 webcast tribute to Ingenuity. "They demonstrated an approach that if we use in the future will really help us to explore other planets and be as awe-inspiring, as amazing, as Ingenuity has been."

Ascent Solar Technologies’ Solar Modules to Be Deployed on NASA’s Upcoming LISA-T Mission – SolarQuarter

Ascent Solar Technologies, a pioneering U.S. firm specializing in featherweight, flexible, and robust CIGS thin-film photovoltaic (PV) solutions, has announced that its solar module products will be part of NASAs upcoming Lightweight Integrated Solar Array and AnTenna (LISA-T) mission, set to launch this summer. This mission, spearheaded by NASAs Space Technology Mission Directorate and the Marshall Space Flight Center in Huntsville, aims to showcase the deployment of large-area arrays on lightweight, cost-effective, and small spacecraft.

LISA-T constitutes the fourth mission in NASAs Pathfinder Technology Demonstrator (PTD) series, which assesses novel capabilities of small spacecraft in orbit. Managed by NASAs Ames Research Center in Silicon Valley, these demonstration missions facilitate the integration of new technologies into future science and exploration missions. The solar arrays of LISA-T (PTD-4) boast lower mass and stowed volume while producing three times more power compared to alternative PV solutions within the system envelope. Additionally, PTD-4s deployable solar arrays are designed to scale larger than the missions CubeSat form factor, offering options capable of generating kilowatts of power for small spacecraft.

Paul Warley, CEO of Ascent Solar Technologies, expressed pride in the companys selection for the upcoming space mission, attributing it to years of collaboration with NASA to optimize PV modules that align with LISA-Ts ambitious spacecraft mass and power requirements. He emphasized the significance of public-private partnerships in advancing innovative technologies, noting how programs like MISSE and PTD pave the way for more capable spacecraft for both government and commercial space missions. The modules developed for LISA-T have also influenced the design of Ascents Titan line of space products, enabling further enhancement of power generation capabilities in the space environment.

Leading up to the spacecraft demonstration, Ascents PV products underwent evaluations on the International Space Station, with modules tested on NASAs MISSE-X experiment affirming the resilience of the companys CIGS material in space conditions. Furthermore, additional Ascent modules featuring lower-cost and lighter-weight laminates are undergoing assessment on the upcoming MISSE payload slated to fly on SpaceXs 30th Commercial Resupply Mission to the space station in March.

NASA will retire the ISS soon. Here’s what comes next. – NPR

The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around of the orbiting lab on Nov. 8, 2021. NASA hide caption

The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around of the orbiting lab on Nov. 8, 2021.

Since its first modules launched at the end of 1998, the International Space Station has been orbiting 250 miles above Earth. But at the end of 2030, NASA plans to crash the ISS into the ocean after it is replaced with a new space station, a reminder that nothing within Earth's orbit can stay in space forever.

NASA is collaborating on developing a space station owned, built, and operated by a private company either Axiom Space, Voyager Space, or Blue Origin. NASA is giving each company hundreds of millions of dollars in funding and sharing their expertise with them.

Eventually, they will select one company to officially partner with and have them replace the ISS. NASA says this will help them focus on deep space exploration, which they consider a much more difficult task.

But any company that is able to develop their own space station, get approval from the federal government and launch it into space will be able to pursue their own deep space missions even without the approval of NASA.

Phil McCalister, director of the Commercial Space Division of NASA, told NPR's Morning Edition that NASA does not want to own in perpetuity everything in low-Earth orbit which is up to 1,200 miles above Earth's surface.

"We want to turn those things over to other organizations that could potentially do it more cost-effectively, and then focus our research and activities on deep space exploration," said McCalister.

McCalister says the ISS could stay in space longer, but it's much more cost-effective for NASA to acquire a brand new station with new technology. NASA would then transition to purchasing services from commercial entities as opposed to the government building a next-generation commercial space station.

The ISS was designed in the 80s, so the technology when it was first built was very different from what is available today.

"I kind of see this as like an automobile. When we bought that automobile in 1999, it was state of the art. And it has been great. And it serves us well and continues to be safe. But it's getting older. It's getting harder to find spare parts. The maintenance for that is becoming a larger issue," McCalister said.

A new, private space station will have a lot of similarities and some differences from the current ISS.

Robyn Gatens, director of the International Space Station, says that despite it aging, not all the technology on the ISS is out of date.

"We've been evolving the technology on the International Space Station since it was first built. So some of these technologies will carry over to these private space stations," said Gatens. "We've upgraded the batteries, we've upgraded and added solar arrays that roll out and are flexible, we've been upgrading our life support systems."

Paulo Lozano is the director of the Space Propulsion Laboratory at MIT and an aerospace engineer. He said, "NASA has already changed the solar panels at least once and switched them from these very large arrays that produce relatively little power, to these smaller arrays that produce much more power. All the computer power at the beginning is nothing compared to what can be done today."

Gatens says the structure of the space station which is the size of a football field is what can't be upgraded and replaced. And something of that size is costly for NASA to maintain.

"The big structure, even though it's doing very well, has a finite lifetime. It won't last forever. It is affected by the environment that it's in. And every time we dock a vehicle and undock a vehicle, the thermal environment puts stresses and loads on that primary structure that will eventually make it wear out," said Gatens.

Gatens says we can expect a new space station to be designed a little more efficiently and right sized for the amount of research that NASA and its partners are going to want to do in low-Earth orbit.

The structure of the ship is also extremely important to the people who work there.

The ISS carries scientists who perform research that can only be done in the weak gravity of space, like medical research. In space, cells age more quickly and conditions progress more rapidly, helping researchers understand the progression of things like heart disease or cancer more quickly.

Researchers on the ISS also work to understand what happens to the human body when it's exposed to microgravity. This research is aimed at helping develop ways to counteract the negative effects of being in space and let astronauts stay there longer something essential to getting a human on Mars.

Gatens says a new space station will have updated research facilities.

"I'm looking forward to seeing very modern laboratory equipment on these space stations. We say the International Space Station has a lot of capability, but it's more like a test kitchen. I'm looking forward to seeing the future commercial space stations take these laboratory capabilities and really develop them into state-of-the-art space laboratories," said Gatens.

On top of having modern research facilities, new space stations will likely be designed to provide a cleaner environment for researchers.

"If you see pictures of the station, you'll think 'how can they work there?' It looks cluttered, it looks messy," Astronaut Peggy Whitson told NPR. She's spent more time in space than any other woman and is the first woman to command the ISS. Whitson is now Director of Human Spaceflight and an astronaut at Axiom Space, one of the companies funded by NASA to develop a space station.

Whitson said the reason there are cables all over the place is because the structure of the station wasn't designed for some of the systems it has now. She thinks having a method for making a station even more adaptable to new technology will be important in terms of user experience.

Whitson doesn't know what technology will be available five years from now. But she said Axiom Space will want to take advantage of whatever they can get their hands on, ideally without wires everywhere.

"I would like all that cabling and networking to be behind the panels so that it's easier for folks to move around in space," Whitson said. "Having and building in that adaptability is one of the most critical parts, I think, of building a station for low-Earth orbit."

Paulo Lozano says many of the electronic components on the ISS are bulky. But now that electronics are smaller, she expects the interior of future stations might be a bit different.

At the current ISS, there is one small inflatable module. That structure flies up, collapsed, and then expands as it gets filled with air once it's attached to the primary structure of the station with it literally blowing up kind of like a balloon. Gatens says they are looking at multiple elements of a new space station being inflatable.

Whitson told NPR that on the space station Axiom Space is developing, they will have windows in the crew quarters and a huge cupola, what she describes as an astronaut's window to the world. On the ISS, they have a cupola you can pop your head and shoulders into and see 360-degree views of space and look down at the Earth.

On the proposed Axiom space station, Whitson said the cupola is so large that astronauts will be able to float their whole body in there and have it be an experience of basically almost flying in space.

NASA hopes that by handing responsibility of an ISS replacement over to private companies, it will allow the agency to develop technology more quickly and focus on their next goal of putting a station beyond low-Earth orbit for the first time. Current proposed low-Earth orbit stations include the Lunar Gateway, which is NASA's planned space station on the moon.

"What the space stations of today are doing is just paving the way for humans to actually explore deeper into space, which is going to be a significantly harder challenge to accomplish. The space stations of today are essential stepping stones towards that goal," said Lozano.

Gatens says one piece of technology that is being developed at Blue Origin is a big rotating space station that, when finished, would have artificial gravity.

For long trips in space, the lack of gravity is a main issue for the human body, causing bone-loss and other health issues. "If you could recreate that in space, that will be very beneficial," Gatens said.

Lozano says that a space station beyond low-Earth orbit would need new technology that is radically different from what's been used in the ISS. And both NASA and Lozano don't think it is possible to venture deeper into space, and eventually get a human on Mars, with U.S. government funding alone.

"I don't think we're very far away in terms of technology development. I think we're a little bit far away in terms of investment, because space technology is quite expensive and sometimes a single nation cannot really make it work by itself. So you need international cooperation." Lozano said.

NASA – Wikipedia

The National Aeronautics and Space Administration (NASA ) is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research.

NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science.[5][6][7] NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for uncrewed NASA launches.

NASA's science is focused on better understanding Earth through the Earth Observing System;[8] advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program;[9] exploring bodies throughout the Solar System with advanced robotic spacecraft such as New Horizons and planetary rovers such as Perseverance;[10] and researching astrophysics topics, such as the Big Bang, through the James Webb Space Telescope, and the Great Observatories and associated programs.[11]

The agency's administration is located at NASA Headquarters in Washington, DC, and provides overall guidance and direction.[12] Except under exceptional circumstances, NASA civil service employees are required to be US citizens.[13] NASA's administrator is nominated by the President of the United States subject to the approval of the US Senate,[14] and serves at the President's pleasure as a senior space science advisor. The current administrator is Bill Nelson, appointed by President Joe Biden, since May 3, 2021.[15]

NASA operates with four FY2022 strategic goals.[16]

NASA budget requests are developed by NASA and approved by the administration prior to submission to the U.S. Congress. Authorized budgets are those that have been included in enacted appropriations bills that are approved by both houses of Congress and enacted into law by the U.S. president.[17]

NASA fiscal year budget requests and authorized budgets are provided below.

NASA funding and priorities are developed through its six Mission Directorates.

Center-wide activities such as the Chief Engineer and Safety and Mission Assurance organizations are aligned to the headquarters function. The MSD budget estimate includes funds for these HQ functions. The administration operates 10 major field centers with several managing additional subordinate facilities across the country. Each is led by a Center Director (data below valid as of September 1, 2022).

Short 2018 documentary about NASA produced for its 60th anniversary

Beginning in 1946, the National Advisory Committee for Aeronautics (NACA) began experimenting with rocket planes such as the supersonic Bell X-1.[43] In the early 1950s, there was challenge to launch an artificial satellite for the International Geophysical Year (19571958). An effort for this was the American Project Vanguard. After the Soviet space program's launch of the world's first artificial satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. The US Congress, alarmed by the perceived threat to national security and technological leadership (known as the "Sputnik crisis"), urged immediate and swift action; President Dwight D. Eisenhower counseled more deliberate measures. The result was a consensus that the White House forged among key interest groups, including scientists committed to basic research; the Pentagon which had to match the Soviet military achievement; corporate America looking for new business; and a strong new trend in public opinion looking up to space exploration.[44]

On January 12, 1958, NACA organized a "Special Committee on Space Technology", headed by Guyford Stever.[7] On January 14, 1958, NACA Director Hugh Dryden published "A National Research Program for Space Technology", stating,[45]

It is of great urgency and importance to our country both from consideration of our prestige as a nation as well as military necessity that this challenge [Sputnik] be met by an energetic program of research and development for the conquest of space ... It is accordingly proposed that the scientific research be the responsibility of a national civilian agency ... NACA is capable, by rapid extension and expansion of its effort, of providing leadership in space technology.[45]

While this new federal agency would conduct all non-military space activity, the Advanced Research Projects Agency (ARPA) was created in February 1958 to develop space technology for military application.[46]

On July 29, 1958, Eisenhower signed the National Aeronautics and Space Act, establishing NASA.[47] When it began operations on October 1, 1958, NASA absorbed the 43-year-old NACA intact; its 8,000 employees, an annual budget of US$100million, three major research laboratories (Langley Aeronautical Laboratory, Ames Aeronautical Laboratory, and Lewis Flight Propulsion Laboratory) and two small test facilities.[48] Elements of the Army Ballistic Missile Agency and the United States Naval Research Laboratory were incorporated into NASA. A significant contributor to NASA's entry into the Space Race with the Soviet Union was the technology from the German rocket program led by Wernher von Braun, who was now working for the Army Ballistic Missile Agency (ABMA), which in turn incorporated the technology of American scientist Robert Goddard's earlier works.[49] Earlier research efforts within the US Air Force[48] and many of ARPA's early space programs were also transferred to NASA.[50] In December 1958, NASA gained control of the Jet Propulsion Laboratory, a contractor facility operated by the California Institute of Technology.[48]

NASA's first administrator was Dr. T. Keith Glennan who was appointed by President Dwight D. Eisenhower. During his term (19581961) he brought together the disparate projects in American space development research.[51] James Webb led the agency during the development of the Apollo program in the 1960s.[52] James C. Fletcher has held the position twice; first during the Nixon administration in the 1970s and then at the request of Ronald Reagan following the Challenger disaster.[53] Daniel Goldin held the post for nearly 10 years and is the longest serving administrator to date. He is best known for pioneering the "faster, better, cheaper" approach to space programs.[54] Bill Nelson is currently serving as the 14th administrator of NASA.

The NASA seal was approved by Eisenhower in 1959, and slightly modified by President John F. Kennedy in 1961.[55][56] NASA's first logo was designed by the head of Lewis' Research Reports Division, James Modarelli, as a simplification of the 1959 seal.[57] In 1975, the original logo was first dubbed "the meatball" to distinguish it from the newly designed "worm" logo which replaced it. The "meatball" returned to official use in 1992.[57] The "worm" was brought out of retirement by administrator Jim Bridenstine in 2020.[58]

NASA Headquarters in Washington, DC provides overall guidance and political leadership to the agency's ten field centers, through which all other facilities are administered.[59]

Aerial views of the NASA Ames (left) and NASA Armstrong (right) centers

Ames Research Center (ARC) at Moffett Field is located in the Silicon Valley of central California and delivers wind-tunnel research on the aerodynamics of propeller-driven aircraft along with research and technology in aeronautics, spaceflight, and information technology.[60] It provides leadership in astrobiology, small satellites, robotic lunar exploration, intelligent/adaptive systems and thermal protection.

Armstrong Flight Research Center (AFRC) is located inside Edwards Air Force Base and is the home of the Shuttle Carrier Aircraft (SCA), a modified Boeing 747 designed to carry a Space Shuttle orbiter back to Kennedy Space Center after a landing at Edwards AFB. The center focuses on flight testing of advanced aerospace systems.

Glenn Research Center is based in Cleveland, Ohio and focuses on air-breathing and in-space propulsion and cryogenics, communications, power energy storage and conversion, microgravity sciences, and advanced materials.[61]

Goddard Space Flight Center (GSFC), located in Greenbelt, Maryland develops and operates uncrewed scientific spacecraft.[62] GSFC also operates two spaceflight tracking and data acquisition networks (the Space Network and the Near Earth Network), develops and maintains advanced space and Earth science data information systems, and develops satellite systems for the National Oceanic and Atmospheric Administration (NOAA).[62]

Johnson Space Center (JSC) is the NASA center for human spaceflight training, research and flight control.[63] It is home to the United States Astronaut Corps and is responsible for training astronauts from the US and its international partners, and includes the Christopher C. Kraft Jr. Mission Control Center.[64] JSC also operates the White Sands Test Facility in Las Cruces, New Mexico to support rocket testing.

Jet Propulsion Laboratory (JPL), located in the San Gabriel Valley area of Los Angeles County, C and builds and operates robotic planetary spacecraft, though it also conducts Earth-orbit and astronomy missions.[65] It is also responsible for operating NASA's Deep Space Network (DSN).

Langley Research Center (LaRC), located in Hampton, Virginia devotes two-thirds of its programs to aeronautics, and the rest to space. LaRC researchers use more than 40 wind tunnels to study improved aircraft and spacecraft safety, performance, and efficiency. The center was also home to early human spaceflight efforts including the team chronicled in the Hidden Figures story.[66]

Kennedy Space Center (KSC), located west of Cape Canaveral Space Force Station in Florida, has been the launch site for every United States human space flight since 1968. KSC also manages and operates uncrewed rocket launch facilities for America's civil space program from three pads at Cape Canaveral.[67]

Marshall Space Flight Center (MSFC), located on the Redstone Arsenal near Huntsville, Alabama, is one of NASA's largest centers and is leading the development of the Space Launch System in support of the Artemis program. Marshall is NASA's lead center for International Space Station (ISS) design and assembly; payloads and related crew training; and was the lead for Space Shuttle propulsion and its external tank.[68]

Stennis Space Center, originally the "Mississippi Test Facility", is located in Hancock County, Mississippi, on the banks of the Pearl River at the MississippiLouisiana border.[69] Commissioned in October 1961, it is currently used for rocket testing by over 30 local, state, national, international, private, and public companies and agencies.[70][71] It also contains the NASA Shared Services Center.[72]

NASA inherited NACA's X-15 experimental rocket-powered hypersonic research aircraft, developed in conjunction with the US Air Force and Navy. Three planes were built starting in 1955. The X-15 was drop-launched from the wing of one of two NASA Boeing B-52 Stratofortresses, NB52A tail number 52-003, and NB52B, tail number 52-008 (known as the Balls 8). Release took place at an altitude of about 45,000 feet (14km) and a speed of about 500 miles per hour (805km/h).[73]

Twelve pilots were selected for the program from the Air Force, Navy, and NACA. A total of 199 flights were made between June 1959 and December 1968, resulting in the official world record for the highest speed ever reached by a crewed powered aircraft (current as of 2014[update]), and a maximum speed of Mach 6.72, 4,519 miles per hour (7,273km/h).[74] The altitude record for X-15 was 354,200 feet (107.96km).[75] Eight of the pilots were awarded Air Force astronaut wings for flying above 260,000 feet (80km), and two flights by Joseph A. Walker exceeded 100 kilometers (330,000ft), qualifying as spaceflight according to the International Aeronautical Federation. The X-15 program employed mechanical techniques used in the later crewed spaceflight programs, including reaction control system jets for controlling the orientation of a spacecraft, space suits, and horizon definition for navigation.[75] The reentry and landing data collected were valuable to NASA for designing the Space Shuttle.[76]

In 1958, NASA formed an engineering group, the Space Task Group, to manage their human spaceflight programs under the direction of Robert Gilruth. Their earliest programs were conducted under the pressure of the Cold War competition between the US and the Soviet Union. NASA inherited the US Air Force's Man in Space Soonest program, which considered many crewed spacecraft designs ranging from rocket planes like the X-15, to small ballistic space capsules.[77] By 1958, the space plane concepts were eliminated in favor of the ballistic capsule,[78] and NASA renamed it Project Mercury. The first seven astronauts were selected among candidates from the Navy, Air Force and Marine test pilot programs. On May 5, 1961, astronaut Alan Shepard became the first American in space aboard a capsule he named Freedom7, launched on a Redstone booster on a 15-minute ballistic (suborbital) flight.[79] John Glenn became the first American to be launched into orbit, on an Atlas launch vehicle on February 20, 1962, aboard Friendship7.[80] Glenn completed three orbits, after which three more orbital flights were made, culminating in L. Gordon Cooper's 22-orbit flight Faith 7, May 1516, 1963.[81] Katherine Johnson, Mary Jackson, and Dorothy Vaughan were three of the human computers doing calculations on trajectories during the Space Race.[82][83][84] Johnson was well known for doing trajectory calculations for John Glenn's mission in 1962, where she was running the same equations by hand that were being run on the computer.[82]

Mercury's competition from the Soviet Union (USSR) was the single-pilot Vostok spacecraft. They sent the first man in space, cosmonaut Yuri Gagarin, into a single Earth orbit aboard Vostok 1 in April 1961, one month before Shepard's flight.[85] In August 1962, they achieved an almost four-day record flight with Andriyan Nikolayev aboard Vostok 3, and also conducted a concurrent Vostok 4 mission carrying Pavel Popovich.[86]

Based on studies to grow the Mercury spacecraft capabilities to long-duration flights, developing space rendezvous techniques, and precision Earth landing, Project Gemini was started as a two-man program in 1961 to overcome the Soviets' lead and to support the planned Apollo crewed lunar landing program, adding extravehicular activity (EVA) and rendezvous and docking to its objectives. The first crewed Gemini flight, Gemini 3, was flown by Gus Grissom and John Young on March 23, 1965.[87] Nine missions followed in 1965 and 1966, demonstrating an endurance mission of nearly fourteen days, rendezvous, docking, and practical EVA, and gathering medical data on the effects of weightlessness on humans.[88][89]

Under the direction of Soviet Premier Nikita Khrushchev, the USSR competed with Gemini by converting their Vostok spacecraft into a two- or three-man Voskhod. They succeeded in launching two crewed flights before Gemini's first flight, achieving a three-cosmonaut flight in 1964 and the first EVA in 1965.[90] After this, the program was canceled, and Gemini caught up while spacecraft designer Sergei Korolev developed the Soyuz spacecraft, their answer to Apollo.

The U.S. public's perception of the Soviet lead in the Space Race (by putting the first man into space) motivated President John F. Kennedy[91] to ask the Congress on May 25, 1961, to commit the federal government to a program to land a man on the Moon by the end of the 1960s, which effectively launched the Apollo program.[92]

Apollo was one of the most expensive American scientific programs ever. It cost more than $20billion in 1960s dollars[93] or an estimated $236billion in present-day US dollars.[94] (In comparison, the Manhattan Project cost roughly $30.1billion, accounting for inflation.)[94][95] The Apollo program used the newly developed Saturn I and Saturn V rockets, which were far larger than the repurposed ICBMs of the previous Mercury and Gemini programs.[96] They were used to launch the Apollo spacecraft, consisting of the Command and Service Module (CSM) and the Lunar Module (LM). The CSM ferried astronauts from Earth to Moon orbit and back, while the Lunar Module would land them on the Moon itself.[note 1]

The planned first crew of 3 astronauts were killed due to a fire during a 1967 preflight test for the Apollo 204 mission (later renamed Apollo 1).[97] The second crewed mission, Apollo 8, brought astronauts for the first time in a flight around the Moon in December 1968.[98] Shortly before, the Soviets had sent an uncrewed spacecraft around the Moon.[99] The next two missions (Apollo 9 and Apollo 10) practiced rendezvous and docking maneuvers required to conduct the Moon landing.[100][101]

The Apollo 11 mission, launched in July 1969, landed the first humans on the Moon. Astronauts Neil Armstrong and Buzz Aldrin walked on the lunar surface, conducting experiments and sample collection, while Michael Collins orbited above in the CSM.[102] Six subsequent Apollo missions (12 through 17) were launched; five of them were successful, while one (Apollo 13) was aborted after an in-flight emergency nearly killed the astronauts. Throughout these seven Apollo spaceflights, twelve men walked on the Moon. These missions returned a wealth of scientific data and 381.7 kilograms (842lb) of lunar samples. Topics covered by experiments performed included soil mechanics, meteoroids, seismology, heat flow, lunar ranging, magnetic fields, and solar wind.[103] The Moon landing marked the end of the space race; and as a gesture, Armstrong mentioned mankind when he stepped down on the Moon.[104]

On July 3, 1969, the Soviets suffered a major setback on their Moon program when the rocket known as the N-1 had exploded in a fireball at its launch site at Baikonur in Kazakhstan, destroying one of two launch pads. Each of the first four launches of N-1 resulted in failure before the end of the first stage flight effectively denying the Soviet Union the capacity to deliver the systems required for a crewed lunar landing.[105]

Apollo set major milestones in human spaceflight. It stands alone in sending crewed missions beyond low Earth orbit, and landing humans on another celestial body.[106] Apollo 8 was the first crewed spacecraft to orbit another celestial body, while Apollo 17 marked the last moonwalk and the last crewed mission beyond low Earth orbit. The program spurred advances in many areas of technology peripheral to rocketry and crewed spaceflight, including avionics, telecommunications, and computers. Apollo sparked interest in many fields of engineering and left many physical facilities and machines developed for the program as landmarks. Many objects and artifacts from the program are on display at various locations throughout the world, notably at the Smithsonian's Air and Space Museums.

Skylab was the United States' first and only independently built space station.[107] Conceived in 1965 as a workshop to be constructed in space from a spent Saturn IB upper stage, the 169,950lb (77,088kg) station was constructed on Earth and launched on May 14, 1973, atop the first two stages of a Saturn V, into a 235-nautical-mile (435km) orbit inclined at 50 to the equator. Damaged during launch by the loss of its thermal protection and one electricity-generating solar panel, it was repaired to functionality by its first crew. It was occupied for a total of 171 days by 3 successive crews in 1973 and 1974.[107] It included a laboratory for studying the effects of microgravity, and a solar observatory.[107] NASA planned to have the in-development Space Shuttle dock with it, and elevate Skylab to a higher safe altitude, but the Shuttle was not ready for flight before Skylab's re-entry and demise on July 11, 1979.[108]

To reduce cost, NASA modified one of the Saturn V rockets originally earmarked for a canceled Apollo mission to launch Skylab, which itself was a modified Saturn V fuel tank. Apollo spacecraft, launched on smaller Saturn IB rockets, were used for transporting astronauts to and from the station. Three crews, consisting of three men each, stayed aboard the station for periods of 28, 59, and 84 days. Skylab's habitable volume was 11,290 cubic feet (320m3), which was 30.7 times bigger than that of the Apollo Command Module.[108]

In February 1969, President Richard Nixon appointed a space task group headed by Vice President Spiro Agnew to recommend human spaceflight projects beyond Apollo. The group responded in September with the Integrated Program Plan (IPP), intended to support space stations in Earth and lunar orbit, a lunar surface base, and a human Mars landing. These would be supported by replacing NASA's existing expendable launch systems with a reusable infrastructure including Earth orbit shuttles, space tugs, and a nuclear-powered trans-lunar and interplanetary shuttle. Despite the enthusiastic support of Agnew and NASA Administrator Thomas O. Paine, Nixon realized public enthusiasm, which translated into Congressional support, for the space program was waning as Apollo neared its climax, and vetoed most of these plans, except for the Earth orbital shuttle, and a deferred Earth space station.[109]

On May 24, 1972, US President Richard M. Nixon and Soviet Premier Alexei Kosygin signed an agreement calling for a joint crewed space mission, and declaring intent for all future international crewed spacecraft to be capable of docking with each other.[110] This authorized the ApolloSoyuz Test Project (ASTP), involving the rendezvous and docking in Earth orbit of a surplus Apollo command and service module with a Soyuz spacecraft. The mission took place in July 1975. This was the last US human spaceflight until the first orbital flight of the Space Shuttle in April 1981.[111]

The mission included both joint and separate scientific experiments and provided useful engineering experience for future joint USRussian space flights, such as the ShuttleMir program[112] and the International Space Station.

The Space Shuttle was the only vehicle in the Space Transportation System to be developed, and became the major focus of NASA in the late 1970s and the 1980s. Originally planned as a frequently launchable, fully reusable vehicle, the design was changed to use an expendable external propellant tank to reduce development cost, and four Space Shuttle orbiters were built by 1985. The first to launch, Columbia, did so on April 12, 1981, the 20th anniversary of the first human spaceflight.[113]

The Shuttle flew 135 missions and carried 355 astronauts from 16 countries, many on multiple trips. Its major components were a spaceplane orbiter with an external fuel tank and two solid-fuel launch rockets at its side. The external tank, which was bigger than the spacecraft itself, was the only major component that was not reused. The shuttle could orbit in altitudes of 185643 km (115400 miles)[114] and carry a maximum payload (to low orbit) of 24,400 kg (54,000 lb).[115] Missions could last from 5 to 17 days and crews could be from 2 to 8 astronauts.[114]

On 20 missions (19831998) the Space Shuttle carried Spacelab, designed in cooperation with the European Space Agency (ESA). Spacelab was not designed for independent orbital flight, but remained in the Shuttle's cargo bay as the astronauts entered and left it through an airlock.[116] On June 18, 1983, Sally Ride became the first American woman in space, on board the Space Shuttle Challenger STS-7 mission.[117] Another famous series of missions were the launch and later successful repair of the Hubble Space Telescope in 1990 and 1993, respectively.[118]

In 1995, Russian-American interaction resumed with the ShuttleMir missions (19951998). Once more an American vehicle docked with a Russian craft, this time a full-fledged space station. This cooperation has continued with Russia and the United States as two of the biggest partners in the largest space station built: the International Space Station (ISS).[119] The strength of their cooperation on this project was even more evident when NASA began relying on Russian launch vehicles to service the ISS during the two-year grounding of the shuttle fleet following the 2003 Space Shuttle Columbia disaster.

The Shuttle fleet lost two orbiters and 14 astronauts in two disasters: Challenger in 1986, and Columbia in 2003.[120] While the 1986 loss was mitigated by building the Space Shuttle Endeavour from replacement parts, NASA did not build another orbiter to replace the second loss.[120] NASA's Space Shuttle program had 135 missions when the program ended with the successful landing of the Space Shuttle Atlantis at the Kennedy Space Center on July 21, 2011. The program spanned 30 years with 355 separate astronauts sent into space, many on multiple missions.[121]

While the Space Shuttle program was still suspended after the loss of Columbia, President George W. Bush announced the Vision for Space Exploration including the retirement of the Space Shuttle after completing the International Space Station. The plan was enacted into law by the NASA Authorization Act of 2005 and directs NASA to develop and launch the Crew Exploration Vehicle (later called Orion) by 2010, return Americans to the Moon by 2020, land on Mars as feasible, repair the Hubble Space Telescope, and continue scientific investigation through robotic solar system exploration, human presence on the ISS, Earth observation, and astrophysics research. The crewed exploration goals prompted NASA's Constellation program.[122]

On December 4, 2006, NASA announced it was planning a permanent Moon base.[123] The goal was to start building the Moon base by 2020, and by 2024, have a fully functional base that would allow for crew rotations and in-situ resource utilization. However, in 2009, the Augustine Committee found the program to be on an "unsustainable trajectory."[124] In February 2010, President Barack Obama's administration proposed eliminating public funds for it.[125]

President Obama's plan was to develop American private spaceflight capabilities to get astronauts to the International Space Station, replace Russian Soyuz capsules, and use Orion capsules for ISS emergency escape purposes. During a speech at the Kennedy Space Center on April 15, 2010, Obama proposed a new heavy-lift vehicle (HLV) to replace the formerly planned Ares V.[126] In his speech, Obama called for a crewed mission to an asteroid as soon as 2025, and a crewed mission to Mars orbit by the mid-2030s.[126] The NASA Authorization Act of 2010 was passed by Congress and signed into law on October 11, 2010.[127] The act officially canceled the Constellation program.[127]

The NASA Authorization Act of 2010 required a newly designed HLV be chosen within 90 days of its passing; the launch vehicle was given the name Space Launch System. The new law also required the construction of a beyond low earth orbit spacecraft.[128] The Orion spacecraft, which was being developed as part of the Constellation program, was chosen to fulfill this role.[129] The Space Launch System is planned to launch both Orion and other necessary hardware for missions beyond low Earth orbit.[130] The SLS is to be upgraded over time with more powerful versions. The initial capability of SLS is required to be able to lift 70t (150,000lb) (later 95t or 209,000lb) into LEO. It is then planned to be upgraded to 105t (231,000lb) and then eventually to 130t (290,000lb).[129][131] The Orion capsule first flew on Exploration Flight Test 1 (EFT-1), an uncrewed test flight that was launched on December 5, 2014, atop a Delta IV Heavy rocket.[131]

NASA undertook a feasibility study in 2012 and developed the Asteroid Redirect Mission as an uncrewed mission to move a boulder-sized near-Earth asteroid (or boulder-sized chunk of a larger asteroid) into lunar orbit. The mission would demonstrate ion thruster technology and develop techniques that could be used for planetary defense against an asteroid collision, as well as a cargo transport to Mars in support of a future human mission. The Moon-orbiting boulder might then later be visited by astronauts. The Asteroid Redirect Mission was cancelled in 2017 as part of the FY2018 NASA budget, the first one under President Donald Trump.[132]

NASA has conducted many uncrewed and robotic spaceflight programs throughout its history. Uncrewed robotic programs launched the first American artificial satellites into Earth orbit for scientific and communications purposes and sent scientific probes to explore the planets of the Solar System, starting with Venus and Mars, and including "grand tours" of the outer planets. More than 1,000 uncrewed missions have been designed to explore the Earth and the Solar System.[133]

The first US uncrewed satellite was Explorer 1, which started as an ABMA/JPL project during the early part of the Space Race. It was launched in January 1958, two months after Sputnik. At the creation of NASA, the Explorer project was transferred to the agency and still continues. Its missions have been focusing on the Earth and the Sun, measuring magnetic fields and the solar wind, among other aspects.[134]

The Ranger missions developed technology to build and deliver robotic probes into orbit and to the vicinity of the Moon. Ranger 7 successfully returned images of the Moon in July 1964, followed by two more successful missions.[135]

NASA also played a role in the development and delivery of early communications satellite technology to orbit. Syncom 3 was the first geostationary satellite. It was an experimental geosynchronous communications satellite placed over the equator at 180 degrees longitude in the Pacific Ocean. The satellite provided live television coverage of the 1964 Olympic games in Tokyo, Japan and conducted various communications tests. Operations were turned over to the Department of Defense on January 1, 1965; Syncom 3 was to prove useful in the DoD's Vietnam communications.[136] Programs like Syncom, Telstar, and Applications Technology Satellites (ATS) demonstrated the utility of communications satellites and delivered early telephonic and video satellite transmission.[137]

Study of Mercury, Venus, or Mars has been the goal of more than ten uncrewed NASA programs. The first was Mariner in the 1960s and 1970s, which made multiple visits to Venus and Mars and one to Mercury. Probes launched under the Mariner program were also the first to make a planetary flyby (Mariner 2), to take the first pictures from another planet (Mariner 4), the first planetary orbiter (Mariner 9), and the first to make a gravity assist maneuver (Mariner 10). This is a technique where the satellite takes advantage of the gravity and velocity of planets to reach its destination.[138]

Magellan orbited Venus for four years in the early 1990s capturing radar images of the planet's surface.[139] MESSENGER orbited Mercury between 2011 and 2015 after a 6.5-year journey involving a complicated series of flybys of Venus and Mercury to reduce velocity sufficiently enough to enter Mercury orbit. MESSENGER became the first spacecraft to orbit Mercury and used its science payload to study Mercury's surface composition, geological history, internal magnetic field, and verified its polar deposits were dominantly water-ice.[140]

From 1966 to 1968, the Lunar Orbiter and Surveyor missions provided higher quality photographs and other measurements to pave the way for the crewed Apollo missions to the Moon.[141] Clementine spent a couple of months mapping the Moon in 1994 before moving on to other mission objectives.[142] Lunar Prospector spent 19 months from 1998 mapping the Moon's surface composition and looking for polar ice.[143]

The first successful landing on Mars was made by Viking 1 in 1976. Viking 2 followed two months later. Twenty years later the Sojourner rover was landed on Mars by Mars Pathfinder.[144]

After Mars, Jupiter was first visited by Pioneer 10 in 1973. More than 20 years later Galileo sent a probe into the planet's atmosphere and became the first spacecraft to orbit the planet.[145] Pioneer 11 became the first spacecraft to visit Saturn in 1979, with Voyager 2 making the first (and so far, only) visits to Uranus and Neptune in 1986 and 1989, respectively. The first spacecraft to leave the Solar System was Pioneer 10 in 1983. For a time, it was the most distant spacecraft, but it has since been surpassed by both Voyager 1 and Voyager 2.[146]

Pioneers 10 and 11 and both Voyager probes carry messages from the Earth to extraterrestrial life.[147][148] Communication can be difficult with deep space travel. For instance, it took about three hours for a radio signal to reach the New Horizons spacecraft when it was more than halfway to Pluto.[149] Contact with Pioneer 10 was lost in 2003. Both Voyager probes continue to operate as they explore the outer boundary between the Solar System and interstellar space.[150]

NASA continued to support in situ exploration beyond the asteroid belt, including Pioneer and Voyager traverses into the unexplored trans-Pluto region, and gas giant orbiters Galileo (19892003) and Cassini (19972017) exploring the Jovian and Saturnian systems respectively.

The missions below represent the robotic spacecraft that have been delivered and operated by NASA to study the heliosphere. The Helios A and Helios B missions were launched in the 1970s to study the Sun and were the first spacecraft to orbit inside of Mercury's orbit.[151] The Fast Auroral Snapshot Explorer (FAST) mission was launched in August 1996 becoming the second SMEX mission placed in orbit. It studied the auroral zones near each pole during its transits in a highly elliptical orbit.[152]

The International Earth-Sun Explorer-3 (ISEE-3) mission was launched in 1978 and is the first spacecraft designed to operate at the Earth-Sun L1 libration point. It studied solar-terrestrial relationships at the outermost boundaries of the Earth's magnetosphere and the structure of the solar wind. The spacecraft was subsequently maneuvered out of the halo orbit and conducted a flyby of the Giacobini-Zinner comet in 1985 as the rechristened International Cometary Explorer (ICE).[153]

Ulysses was launched in 1990 and slingshotted around Jupiter to put it in an orbit to travel over the poles of the Sun. It was designed study the space environment above and below the poles and delivered scientific data for about 19 years.[154]

Additional spacecraft launched for studies of the heliosphere include: Cluster II, IMAGE, POLAR, Reuven Ramaty High Energy Solar Spectroscopic Imager, and the Van Allen Probes.

The Earth Sciences Division of the NASA Science Mission Directorate leads efforts to study the planet Earth. Spacecraft have been used to study Earth since the mid-1960s. Efforts included the Television Infrared Observation Satellite (TIROS) and Nimbus satellite systems of which there were many carrying weather research and forecasting from space from 1960 into the 2020s.

The Combined Release and Radiation Effects Satellite (CRRES) was launched in 1990 on a three-year mission to investigate fields, plasmas, and energetic particles inside the Earth's magnetosphere.[155] The Upper Atmosphere Research Satellite (UARS) was launched in 1991 by STS-48 to study the Earth's atmosphere especially the protective ozone layer.[156] TOPEX/Poseidon was launched in 1992 and was the first significant oceanographic research satellite.[157]

The Ice, Cloud, and land Elevation Satellite (ICESat) was launched in 2003, operated for seven years, and measured ice sheet mass balance, cloud and aerosol heights, and well as topography and vegetation characteristics.[158]

Over a dozen past robotic missions have focused on the study of the Earth and its environment. Some of these additional missions include Aquarius, Earth Observing-1 (EO-1), Jason-1, Ocean Surface Topography Mission/Jason-2, and Radarsat-1 missions.

The International Space Station (ISS) combines NASA's Space Station Freedom project with the Soviet/Russian Mir-2 station, the European Columbus station, and the Japanese Kib laboratory module.[159] NASA originally planned in the 1980s to develop Freedom alone, but US budget constraints led to the merger of these projects into a single multi-national program in 1993, managed by NASA, the Russian Federal Space Agency (RKA), the Japan Aerospace Exploration Agency (JAXA), the European Space Agency (ESA), and the Canadian Space Agency (CSA).[160][161] The station consists of pressurized modules, external trusses, solar arrays and other components, which were manufactured in various factories around the world, and have been launched by Russian Proton and Soyuz rockets, and the US Space Shuttles.[159] The on-orbit assembly began in 1998, the completion of the US Orbital Segment occurred in 2009 and the completion of the Russian Orbital Segment occurred in 2010, though there are some debates of whether new modules should be added in the segment. The ownership and use of the space station is established in intergovernmental treaties and agreements[162] which divide the station into two areas and allow Russia to retain full ownership of the Russian Orbital Segment (with the exception of Zarya),[163][164] with the US Orbital Segment allocated between the other international partners.[162]

Long-duration missions to the ISS are referred to as ISS Expeditions. Expedition crew members typically spend approximately six months on the ISS.[165] The initial expedition crew size was three, temporarily decreased to two following the Columbia disaster. Since May 2009, expedition crew size has been six crew members.[166] Crew size is expected to be increased to seven, the number the ISS was designed for, once the Commercial Crew Program becomes operational.[167] The ISS has been continuously occupied for the past 22years and 73days, having exceeded the previous record held by Mir; and has been visited by astronauts and cosmonauts from 15 different nations.[168][169]

The station can be seen from the Earth with the naked eye and, as of 2023, is the largest artificial satellite in Earth orbit with a mass and volume greater than that of any previous space station.[170] The Russian Soyuz and American Dragon spacecraft are used to send astronauts to and from the ISS. Several uncrewed cargo spacecraft provide service to the ISS; they are the Russian Progress spacecraft which has done so since 2000, the European Automated Transfer Vehicle (ATV) since 2008, the Japanese H-II Transfer Vehicle (HTV) since 2009, the (uncrewed) Dragon since 2012, and the American Cygnus spacecraft since 2013.[171][172] The Space Shuttle, before its retirement, was also used for cargo transfer and would often switch out expedition crew members, although it did not have the capability to remain docked for the duration of their stay. Between the retirement of the Shuttle in 2011 and the commencement of crewed Dragon flights in 2020, American astronauts exclusively used the Soyuz for crew transport to and from the ISS[173] The highest number of people occupying the ISS has been thirteen; this occurred three times during the late Shuttle ISS assembly missions.[174]

The ISS program is expected to continue to 2030,[175] after which the space station will be retired and destroyed in a controlled de-orbit.[176]

Commercial Resupply Services missions approaching International Space Station

Commercial Resupply Services (CRS) are a contract solution to deliver cargo and supplies to the International Space Station (ISS) on a commmercial basis.[177] NASA signed its first CRS contracts in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences[note 2] for eight Cygnus flights, covering deliveries to 2016. Both companies evolved or created their launch vehicle products to support the solution (SpaceX with The Falcon 9 and Orbital with the Antares).

SpaceX flew its first operational resupply mission (SpaceX CRS-1) in 2012.[178] Orbital Sciences followed in 2014 (Cygnus CRS Orb-1).[179] In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK.[note 2][180][181]

A second phase of contracts (known as CRS-2) was solicited in 2014; contracts were awarded in January 2016 to Orbital ATK[note 2] Cygnus, Sierra Nevada Corporation Dream Chaser, and SpaceX Dragon 2, for cargo transport flights beginning in 2019 and expected to last through 2024. In March 2022, NASA awarded an additional six CRS-2 missions each to both SpaceX and Northrop Grumman (formerly Orbital).[182]

Northrop Grumman successfully delivered Cygnus NG-17 to the ISS in February 2022.[183] In July 2022, SpaceX launched its 25th CRS flight (SpaceX CRS-25) and successfully delivered its cargo to the ISS.[184] In late 2022, Sierra Nevada continued to assemble their Dream Chaser CRS solution; current estimates put its first launch in early 2023.[185]

The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational some time after 2022[needs update].[186] NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.[187]

The spacecraft are owned and operated by the vendor, and crew transportation is provided to NASA as a commercial service. Each mission sends up to four astronauts to the ISS, with an option for a fifth passenger available. Operational flights occur approximately once every six months for missions that last for approximately six months. A spacecraft remains docked to the ISS during its mission, and missions usually overlap by at least a few days. Between the retirement of the Space Shuttle in 2011 and the first operational CCP mission in 2020, NASA relied on the Soyuz program to transport its astronauts to the ISS.

A Crew Dragon spacecraft is launched to space atop a Falcon 9 Block 5 launch vehicle and the capsule returns to Earth via splashdown in the ocean near Florida. The program's first operational mission, SpaceX Crew-1, launched on 16 November 2020.[188] Boeing Starliner operational flights will now commence after its final test flight which was launched atop an Atlas V N22 launch vehicle. Instead of a splashdown, a Starliner capsule returns on land with airbags at one of four designated sites in the western United States.[189]

Since 2017, NASA's crewed spaceflight program has been the Artemis program, which involves the help of US commercial spaceflight companies and international partners such as ESA, JAXA, and CSA.[190] The goal of this program is to land "the first woman and the next man" on the lunar south pole region by 2024. Artemis would be the first step towards the long-term goal of establishing a sustainable presence on the Moon, laying the foundation for companies to build a lunar economy, and eventually sending humans to Mars.

The Orion Crew Exploration Vehicle was held over from the canceled Constellation program for Artemis. Artemis 1 was the uncrewed initial launch of Space Launch System (SLS) that would also send an Orion spacecraft on a Distant Retrograde Orbit.[191]

NASA's next major space initiative is to be the construction of the Lunar Gateway, a small space station in lunar orbit.[192] This space station will be designed primarily for non-continuous human habitation. The first tentative steps of returning to crewed lunar missions will be Artemis 2, which is to include the Orion crew module, propelled by the SLS, and is to launch in 2024.[190] This mission is to be a 10-day mission planned to briefly place a crew of four into a Lunar flyby.[131] The construction of the Gateway would begin with the proposed Artemis 3, which is planned to deliver a crew of four to Lunar orbit along with the first modules of the Gateway. This mission would last for up to 30 days. NASA plans to build full scale deep space habitats such as the Lunar Gateway and the Nautilus-X as part of its Next Space Technologies for Exploration Partnerships (NextSTEP) program.[193] In 2017, NASA was directed by the congressional NASA Transition Authorization Act of 2017 to get humans to Mars-orbit (or to the Martian surface) by the 2030s.[194][195]

In support of the Artemis missions, NASA has been funding private companies to land robotic probes on the lunar surface in a program known as the Commercial Lunar Payload Services. As of March 2022, NASA has awarded contracts for robotic lunar probes to companies such as Intuitive Machines, Firefly Space Systems, and Astrobotic.[196]

On April 16, 2021, NASA announced they had selected the SpaceX Lunar Starship as its Human Landing System. The agency's Space Launch System rocket will launch four astronauts aboard the Orion spacecraft for their multi-day journey to lunar orbit where they will transfer to SpaceX's Starship for the final leg of their journey to the surface of the Moon.[197]

In November 2021, it was announced that the goal of landing astronauts on the Moon by 2024 had slipped to no earlier than 2025 due to numerous factors. Artemis 1 launched on November 16, 2022 and returned to Earth safely on December 11, 2022. As of June 2022, NASA plans to launch Artemis 2 in May 2024 and Artemis 3 sometime in 2025.[198][199] Additional Artemis missions, Artemis 4 and Artemis 5, are planned to launch after 2025.[200]

The Commercial Low Earth Orbit Destinations program is an initiative by NASA to support work on commercial space stations that the agency hopes to have in place by the end of the current decade to replace the "International Space Station". The three selected companies are: Blue Origin (et al.) with their Orbital Reef station concept, Nanoracks (et al.) with their Starlab Space Station concept, and Northrop Grumman with a station concept based on the HALO-module for the Gateway station.[201]

NASA has conducted many uncrewed and robotic spaceflight programs throughout its history. More than 1,000 uncrewed missions have been designed to explore the Earth and the Solar System.[133]

NASA executes a mission development framework to plan, select, develop, and operate robotic missions. This framework defines cost, schedule and technical risk parameters to enable competitive selection of missions involving mission candidates that have been developed by principal investigators and their teams from across NASA, the broader U.S. Government research and development stakeholders, and industry. The mission development construct is defined by four umbrella programs.

The Explorer program derives its origin from the earliest days of the U.S. Space program. In current form, the program consists of three classes of systems - Small Explorers (SMEX), Medium Explorers (MIDEX), and University-Class Explorers (UNEX) missions. The NASA Explorer program office provides frequent flight opportunities for moderate cost innovative solutions from the heliophysics and astrophysics science areas. The Small Explorer missions are required to limit cost to NASA to below $150M (2022 dollars). Medium class explorer missions have typically involved NASA cost caps of $350M. The Explorer program office is based at NASA Goddard Space Flight Center.[202]

The NASA Discovery program develops and delivers robotic spacecraft solutions in the planetary science domain. Discovery enables scientists and engineers to assemble a team to deliver a solution against a defined set of objectives and competitively bid that solution against other candidate programs. Cost caps vary but recent mission selection processes were accomplished using a $500M cost cap to NASA. The Planetary Mission Program Office is based at the NASA Marshall Space Flight Center and manages both the Discovery and New Frontiers missions. The office is part of the Science Mission Directorate.[203]

NASA Administrator Bill Nelson announced on June 2, 2021, that the DAVINCI+ and VERITAS missions were selected to launch to Venus in the late 2020s, having beat out competing proposals for missions to Jupiter's volcanic moon Io and Neptune's large moon Triton that were also selected as Discovery program finalists in early 2020. Each mission has an estimated cost of $500 million, with launches expected between 2028 and 2030. Launch contracts will be awarded later in each mission's development.[204]

The New Frontiers program focuses on specific Solar System exploration goals identified as top priorities by the planetary science community. Primary objectives include Solar System exploration employing medium class spacecraft missions to conduct high-science-return investigations. New Frontiers builds on the development approach employed by the Discovery program but provides for higher cost caps and schedule durations than are available with Discovery. Cost caps vary by opportunity; recent missions have been awarded based on a defined cap of $1 Billion. The higher cost cap and projected longer mission durations result in a lower frequency of new opportunities for the program - typically one every several years. OSIRIS-REx and New Horizons are examples of New Frontiers missions.[205]

Amazing Video Shows What the ISS Would Look Like If It Flew at the Height of a Jetplane

What would happen if the International Space Station was circling the planet at the altitude of an airplane? This video shows what that would look like.

Whoosh

What would happen if the International Space Station was orbiting the planet not hundreds of miles above the surface, but right up close, at the altitude of, say, a commercial jetliner?

In a new video, airplane enthusiast Benjamin Granville used the popular game Microsoft Flight Simulator to show what the space station would look like at just 10,000 feet in altitude— and the results are equal parts amazing and terrifying.

The video shows the ISS blasting across the sky at ludicrous speeds — roughly 17,150 miles per hour, or five miles per second to be exact — in a stunning demonstration of blistering velocity that objects in low-earth orbit need to maintain.

In other words, if you were standing below and trying to take a picture of it, you'd need to be extremely well prepared as you'd only have a fraction of a second to hit the shutter.

Speed Record

Of course, such a maneuver could never be pulled off in real life. Not only would the space station need to overcome a monstrous amount of air resistance, it would also need a ludicrous amount of propulsion to maintain its velocity.

And that's not to mention the fact that, unlike an airplane, the space station would simply fall out of the sky and succumb to gravity, since it's not designed to glide through the air.

But it's a fun demonstration, nonetheless, of the extraordinary speed of an object that — from far away, at least — seems to be peacefully drifting through the night sky.

NASA Releases Hubble Images of Star Right as It Explodes

The Hubble Space Telescope captured three magnificent stages of a star right as it exploded — but it's gone unnoticed until now.

Lucky Shot

To see a star right as it explodes in a supernova is extremely rare. Luckily, researchers combing through the archives of the Hubble Space Telescope's observational data from 2010 have spotted imagery of an exploding star from some 11 billion years ago, lurking behind a galaxy cluster — making it the first time such an event has been observed from so early in the universe.

"It is quite rare that a supernova can be detected at a very early stage, because that stage is really short," said Wenlei Chen, who is the lead author of an accompanying study published in the journal Nature and a researcher at the University of Minnesota School of Physics and Astronomy, in a NASA statement.

"It only lasts for hours to a few days, and it can be easily missed even for a nearby detection," he added. "In the same exposure, we are able to see a sequence of the images — like multiple faces of a supernova."

Third time’s the charm?

Warped Perception

The faraway supernova was revealed due to a phenomenon known as gravitational lensing. When the gravity of a galaxy warps and magnifies the light behind it, it allows telescopes to observe distant objects that would otherwise be too faint.

Amazingly, the warping proved to be an even greater boon than expected, because it resulted in multiple images, or "three faces," from different time periods to be captured in one go. Light from separate moments in the supernova traveled varying distances through the lensing and were in effect slowed down due to the immense gravity of the lens galaxy, causing the different "routes" of light to all arrive at the same time.

Thanks to that instant timelapse, the researchers were able to measure the supernova's rate of cooling and calculated the star's size before it exploded. They believe it was a red giant over 500 times larger than the Sun.

"You see different colors in the three different images," said Patrick Kelly, who led the study and is an assistant professor in the University of Minnesota's School of Physics and Astronomy, in the statement. "You've got the massive star, the core collapses, it produces a shock, it heats up, and then you're seeing it cool over a week. I think that's probably one of the most amazing things I've ever seen!"
