In September 1969, celebrations continued to mark the successful first human Moon landing two months earlier, and NASA prepared for the next visit to the Moon. The hometowns of the Apollo 11 astronauts held parades in their honor, the postal service recognized their accomplishment with a stamp, and the Smithsonian put a Moon rock on display. They addressed Congress and embarked on a 38-day presidential round the world goodwill tour. Eager scientists received the first samples of lunar material to study in their laboratories. Meanwhile, NASA prepared Apollo 12 for November launch as the astronauts trained for the mission with an increased emphasis on lunar science. Plans called for additional Moon landings in 1970, with spacecraft under construction and astronauts in training.

Apollo 11

For Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin, their busy August 1969 postflight schedule continued into September with events throughout the United States and beyond. These included attending hometown parades, dedicating a stamp to commemorate their historic mission, unveiling a display of a Moon rock they collected, addressing a Joint Meeting of Congress, and visiting contractor facilities that built parts of their rocket and spacecraft. They capped off the hectic month with their departure, accompanied by their wives, on a presidential round-the-world goodwill tour that lasted into early November.

On Sep. 6, each astronaut appeared at hometown events held in their honor. Apollo 11 Commander Armstrong’s hometown of Wapakoneta, Ohio, welcomed him with a parade and other events.  Montclair, New Jersey, held a parade to honor hometown hero Lunar Module Pilot (LMP) Aldrin. And New Orleans, Louisiana, the adopted hometown of Command Module Pilot (CMP) Michael Collins, honored him with a parade.

Three days later, the astronauts reunited in Washington, D.C., where they appeared at the dedication ceremony of a new postage stamp that honored their mission. The U.S. Postal Service had commissioned artist Paul Calle in 1968 to design the stamp. The Apollo 11 astronauts had carried the stamp’s master die to the Moon aboard the Lunar Module (LM) Eagle and after its return to Earth the Postal Service used it to make the printing pages for the 10¢ postage stamp. At the National Postal Forum, Armstrong, Collins, and Aldrin unveiled the stamp together with Postmaster General Winton M. Blount, and each astronaut received an album with 30 of the “First Man on the Moon” stamps. On Sep. 15, the crew returned to Washington to present a two-pound rock they collected in the Sea of Tranquility during their historic Moon walk to Frank A. Taylor, the Director General of Museums at the Smithsonian Institution in Washington, D.C. The rock went on public display two days later at the Smithsonian’s Arts and Industries Building, the first time the public could view a Moon rock.

Right: The Apollo 11 astronauts and their wives cut at a cake at a reception at the Capitol.

With their wives observing from the Visitors Gallery of the House of Representatives, on Sep. 16 Armstrong, Aldrin, and Collins addressed a Joint Meeting of Congress. In this same chamber in May 1961, President John F. Kennedy committed the nation to land a man on the Moon and return him safely to the Earth before the end of decade. In a sense, the astronauts reported on the safe and successful completion of that challenge. Speaker of the House John W. McCormack introduced the astronauts to the gathering, as Vice President Spiro T. Agnew looked on. Each astronaut reflected on the significance of the historic mission.

Armstrong noted that their journey truly began in the halls of Congress when the Space Act of 1958 established NASA. Aldrin commented that “the Apollo lesson is that national goals can be met when there is a strong enough will to do so.” Collins shared a favorite quotation of his father’s to describe the value of the Apollo 11 mission: “He who would bring back the wealth of the Indies must take the wealth of the Indies with him.” Armstrong closed with, “We thank you, on behalf of all the men of Apollo, for giving us the privilege of joining you in serving – for all mankind.” After their speeches, the astronauts presented one American flag each to Vice President Agnew in his role as President of the Senate and to Speaker McCormack. The flags, that had flown over the Senate and House of Representatives, had traveled to the Moon and back with the astronauts. Speaker McCormack recognized the astronauts’ wives Jan Armstrong, Joan Aldrin, and Pat Collins for their contributions to the success of the Apollo 11 mission.

On Sep. 26, Armstrong and Collins visited two facilities in California of North American Rockwell (NAR) Space Division, the company that built parts of the Saturn V rocket and Apollo 11 spacecraft. First, they stopped at the Seal Beach plant that built the S-II second stage of the rocket, where 3,000 employees turned out to welcome them. Armstrong commented to the assembled crowd that during the July 16, 1969, liftoff, “the S-II gave us the smoothest ride ever.” Collins added that despite earlier misgivings about using liquid hydrogen as a rocket fuel, “after the ride you people gave us, I sure don’t have doubts any longer.” About 7,000 employees greeted the two astronauts and showered them with confetti at their next stop, the facility in Downey that built the Apollo Command and Service Modules. Both Armstrong and Collins thanked the team for building an outstanding spacecraft that took them to the Moon and returned them safely to Earth. The astronauts inspected the Command Module (CM) for Apollo 14, then under construction at the plant.

On the morning of Sep. 29, a blue and white Boeing VC-137B presidential jet touched down at Ellington Air Force Base in Houston. Neil and Jan Armstrong, Buzz and Joan Aldrin, and Mike and Pat Collins boarded the plane and joined their entourage of State Department and NASA support personnel. They departed Houston for Mexico City, the first stop on the Apollo 11 Giantstep goodwill world tour. They didn’t return to the United States until Nov. 5, having visited 29 cities in 24 countries, just nine days before Apollo 12 took off on humanity’s second journey to land on the Moon.

Back in Houston, distribution to scientists of samples of the lunar material returned by the Apollo 11 astronauts began on Sep. 17 at the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Daniel H. Anderson, curator of lunar samples at the LRL, supervised the distribution of approximately 18 pounds – about one-third of the total Apollo 11 lunar material – to 142 principal investigators from the United States and eight other countries according to prior agreements. The scientists examined the samples at their home institutions and reported their results at a conference in Houston in January 1970. They returned to the LRL any of the samples not destroyed during the examination process.

Apollo 12

In September 1969, NASA continued preparations for the second Moon landing mission, Apollo 12, scheduled for launch on Nov. 14. The Apollo 12 mission called for a pinpoint landing in Oceanus Procellarum (Ocean of Storms) near where the robotic spacecraft Surveyor 3 had touched down in April 1967. They planned to stay on the lunar surface for about 32 hours, compared to Apollo 11’s 21 hours, and conduct two surface spacewalks totaling more than 5 hours. During the first of their two excursions, the astronauts planned to deploy the Apollo Lunar Surface Experiments Package (ALSEP) and collect lunar samples. During the second spacewalk, they planned to visit Surveyor 3 and remove some of its equipment for return to Earth and collect additional lunar samples. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, CMP Richard F. Gordon, and LMP Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin continued intensive training for the mission.

Right: Apollo 12 astronauts Alan L. Bean, left, Richard F. Gordon, and Charles “Pete” Conrad pose in front of their Saturn V during the rollout to the pad.

On Sep. 8, the Saturn V rocket with the Apollo 12 spacecraft on top rolled out from Kennedy Space Center’s (KSC) Vehicle Assembly Building to Launch Pad 39A. The rocket made the 3.5-mile trip to the pad in about 6 hours, with Conrad, Gordon, and Bean on hand to observe the rollout. Workers at the pad spent the next two months thoroughly checking out the rocket and spacecraft to prepare it for its mission to the Moon. The two-day Flight Readiness Test at the end of September ensured that the launch vehicle and spacecraft systems were in a state of flight readiness. In addition to spending many hours in the spacecraft simulators, Conrad and Bean as well as their backups Scott and Irwin rehearsed their lunar surface spacewalks including the visit to Surveyor 3. Workers at NASA’s Jet Propulsion Laboratory in Pasadena, California, shipped an engineering model of the robotic spacecraft to KSC, and for added realism, engineers there mounted the model on a slope to match its relative position on the interior of the crater in which it stood on the Moon. Conrad and Scott used the Lunar Landing Training Vehicle (LLTV) at Ellington Air Force Base (AFB) near MSC to train for the final 200 feet of the descent to the lunar surface.

With regard to lunar geology training, the Apollo 12 astronauts had one advantage over their predecessors – they could inspect actual Moon rocks and soil returned by the Apollo 11 crew. On Sep. 19, Conrad and Bean arrived at the LRL, where Lunar Sample Curator Anderson met them. Anderson brought out a few lunar rocks and some lunar soil that scientists had already tested and didn’t require to be stored under vacuum or other special conditions, allowing Conrad and Bean to examine them closely and compare them with terrestrial rocks and soil they had seen during geology training field trips. This first-hand exposure to actual lunar samples significantly augmented Conrad and Bean’s geology training. To highlight the greater emphasis placed on lunar surface science, the Apollo 12 crews (prime and backup) went on six geology field trips compared to just one for the Apollo 11 crews.

Although the Apollo 11 astronauts returned from the Moon in excellent health and scientists found no evidence of any harmful lunar microorganisms, NASA managers still planned to continue the postflight quarantine program for the Apollo 12 crew members, their spacecraft, and the lunar samples they brought back. The first of these measures involved the astronauts donning Biological Isolation Garments (BIG) prior to exiting the spacecraft after splashdown. Since they didn’t carry the BIGs with them to the Moon and back, one of the recovery personnel, also clad in a BIG, opened the hatch to the capsule after splashdown and handed the suits to the astronauts inside, who donned them before exiting onto a life raft.

On Sep. 20, the Apollo 12 astronauts rehearsed these procedures, identical to the ones used after the first Moon landing mission, in the Gulf of Mexico near Galveston, Texas, using a boilerplate Apollo CM and supported by the Motorized Vessel (MV) Retriever. As it turned out, NASA later removed the requirement for the crew to wear BIGs, and after their splashdown the Apollo 12 crew wore overalls and respirators.

Preparations for Apollo 13 continued in parallel. In KSC’s Manned Spacecraft Operations Building (MSOB), Apollo 13 astronauts completed altitude chamber tests of their mission’s CM and LM. Prime crew members Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise completed the CM altitude test on Sep. 10, followed by their backups John W. Young, Jack L. Swigert, and Charles M. Duke on Sep. 17. The next day, Lovell and Haise completed the altitude test of the LM, followed by Young and Duke on Sep. 22. At the time of these tests, Apollo 13 planned to launch on March 12, 1970, on a 10-day mission to visit the Fra Mauro highlands region of the Moon. To prepare for their lunar surface excursions, Lovell, Haise, Young, and Duke, accompanied by geologist-astronaut Harrison H. “Jack” Schmitt and Caltech geologist Leon T. “Lee” Silver, spent the last week of September in Southern California’s Orocopia Mountains immersed in a geology boot camp.

Looking beyond Apollo 13, the Apollo 14 crew of Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell and their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle had started training for their mission planned for mid-year 1970. At the NAR facility in Downey, engineers prepared the CM and SM and shipped them to KSC in November 1969. Also at Downey, workers continued assembling the CM and SM planned for the Apollo 15 mission in late 1970. As events transpired throughout 1970, plans for those two missions changed significantly.

On Sept. 25, NASA appointed veteran astronaut James A. McDivitt as the Manager of the Apollo Spacecraft Program Office at MSC. McDivitt, selected as an astronaut in 1962, commanded two spaceflights, Gemini IV in June 1965 that included the first American spacewalk and Apollo 9 in March 1969, the first test of the LM in Earth orbit. He succeeded George M. Low who, in that position since April 1967, led the agency’s efforts to recover from the Apollo 1 fire and originated the idea to send Apollo 8 on a lunar orbital mission. Under his tenure, NASA successfully completed five crewed Apollo missions including the first human Moon landing. MSC Director Robert R. Gilruth initially assigned Low to plan future programs until Nov. 13, when President Richard M. Nixon nominated him as NASA deputy administrator. The Senate confirmed Low’s nomination on Nov. 25, and NASA Administrator Thomas O. Paine swore him in on Dec. 3. Low filled the position vacant since March 20, 1969.

      NASA Studies Reveal Hidden Secrets About Interiors of Moon, Vesta
      By NASA
      6 min read
      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept shows the Moon’s hot interior and volcanism about 2 to 3 billion years ago. It is thought that volcanic activity on the lunar near side (the side facing Earth) helped create a landscape dominated by vast plains called mare, which are formed by molten rock that cooled and solidified. NASA/JPL-Caltech Analyzing gravity data collected by spacecraft orbiting other worlds reveals groundbreaking insights about planetary structures without having to land on the surface.
      Although the Moon and the asteroid Vesta are very different, two NASA studies use the same technique to reveal new details about the interiors of both.
      In the lunar study, published May 14 in the journal Nature, researchers developed a new gravity model of the Moon that includes tiny variations in the celestial body’s gravity during its elliptical orbit around Earth. These fluctuations cause the Moon to flex slightly due to Earth’s tidal force — a process called tidal deformation — which provides critical insights into the Moon’s deep internal structure.
      Using their model, the researchers produced the most detailed lunar gravitational map yet, providing future missions an improved way to calculate location and time on the Moon. They accomplished this by analyzing data on the motion of NASA’s GRAIL (Gravity Recovery and Interior Laboratory) mission, whose spacecraft, Ebb and Flow, orbited the Moon from Dec. 31, 2011, to Dec. 17, 2012.
      These views of the Moon’s near side, left, and far side were put together from observations made by NASA’s Lunar Reconnaissance Orbiter. NASA/JPL-Caltech In a second study, published in the journal Nature Astronomy on April 23, the researchers focused on Vesta, an object in the main asteroid belt between Mars and Jupiter. Using NASA’s Deep Space Network radiometric data and imaging data from the agency’s Dawn spacecraft, which orbited the asteroid from July 16, 2011, to Sept. 5, 2012, they found that instead of having distinct layers as expected, Vesta’s internal structure may be mostly uniform, with a very small iron core or no core at all.
      “Gravity is a unique and fundamental property of a planetary body that can be used to explore its deep interior,” said Park. “Our technique doesn’t need data from the surface; we just need to track the motion of the spacecraft very precisely to get a global view of what’s inside.”
      Lunar Asymmetry
      The lunar study looked at gravitational changes to the Moon’s near and far sides. While the near side is dominated by vast plains — known as mare — formed by molten rock that cooled and solidified billions of years ago, the far side is more rugged, with few plains.
      NASA’s Dawn mission obtained this image of the giant asteroid Vesta on July 24, 2011. The spacecraft spent 14 months orbiting the asteroid, capturing more than 30,000 images and fully mapping its surface. NASA/JPL-Caltech/UCLA/MPS/DLR/IDA Both studies were led by Ryan Park, supervisor of the Solar System Dynamics Group at NASA’s Jet Propulsion Laboratory in Southern California, and were years in the making due to their complexity. The team used NASA supercomputers to build a detailed map of how gravity varies across each body. From that, they could better understand what the Moon and Vesta are made of and how planetary bodies across the solar system formed.
      Some theories suggest intense volcanism on the near side likely caused these differences. That process would have caused radioactive, heat-generating elements to accumulate deep inside the near side’s mantle, and the new study offers the strongest evidence yet that this is likely the case.
      “We found that the Moon’s near side is flexing more than the far side, meaning there’s something fundamentally different about the internal structure of the Moon’s near side compared to its far side,” said Park. “When we first analyzed the data, we were so surprised by the result we didn’t believe it. So we ran the calculations many times to verify the findings. In all, this is a decade of work.”
      When comparing their results with other models, Park’s team found a small but greater-than-expected difference in how much the two hemispheres deform. The most likely explanation is that the near side has a warm mantle region, indicating the presence of heat-generating radioactive elements, which is evidence for volcanic activity that shaped the Moon’s near side 2 billion to 3 billion years ago.
      Vesta’s Evolution
      Park’s team applied a similar approach for their study that focused on Vesta’s rotational properties to learn more about its interior.  
      “Our technique is sensitive to any changes in the gravitational field of a body in space, whether that gravitational field changes over time, like the tidal flexing of the Moon, or through space, like a wobbling asteroid,” said Park. “Vesta wobbles as it spins, so we could measure its moment of inertia, a characteristic that is highly sensitive to the internal structure of the asteroid.”
      Changes in inertia can be seen when an ice skater spins with their arms held outward. As they pull their arms in, bringing more mass toward their center of gravity, their inertia decreases and their spin speeds up. By measuring Vesta’s inertia, scientists can gain a detailed understanding of the distribution of mass inside the asteroid: If its inertia is low, there would be a concentration of mass toward its center; if it’s high, the mass would be more evenly distributed.
      Some theories suggest that over a long period, Vesta gradually formed onion-like layers and a dense core. But the new inertia measurement from Park’s team suggests instead that Vesta is far more homogeneous, with its mass distributed evenly throughout and only a small core of dense material, or no core.
      Gravity slowly pulls the heaviest elements to a planet’s center over time, which is how Earth ended up with a dense core of liquid iron. While Vesta has long been considered a differentiated asteroid, a more homogenous structure would suggest that it may not have fully formed layers or may have formed from the debris of another planetary body after a massive impact.
      In 2016, Park used the same data types as the Vesta study to focus on Dawn’s second target, the dwarf planet Ceres, and results suggested a partially differentiated interior.
      Park and his team recently applied a similar technique to Jupiter’s volcanic moon Io, using data acquired by NASA’s Juno and Galileo spacecraft during their flybys of the Jovian satellite as well as from ground-based observations. By measuring how Io’s gravity changes as it orbits Jupiter, which exerts a powerful tidal force, they revealed that the fiery moon is unlikely to possess a global magma ocean.
      “Our technique isn’t restricted just to Io, Ceres, Vesta, or the Moon,” said Park. “There are many opportunities in the future to apply our technique for studying the interiors of intriguing planetary bodies throughout the solar system.”

      NASA Enables Construction Technology for Moon and Mars Exploration
      By NASA

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      ICON’s next generation Vulcan construction system 3D printing a simulated Mars habitat for NASA’s Crew Health and Performance Exploration Analog (CHAPEA) missions.ICON One of the keys to a sustainable human presence on distant worlds is using local, or in-situ, resources which includes building materials for infrastructure such as habitats, radiation shielding, roads, and rocket launch and landing pads. NASA’s Space Technology Mission Directorate is leveraging its portfolio of programs and industry opportunities to develop in-situ, resource capabilities to help future Moon and Mars explorers build what they need. These technologies have made exciting progress for space applications as well as some impacts right here on Earth. 
      The Moon to Mars Planetary Autonomous Construction Technology (MMPACT) project, funded by NASA’s Game Changing Development program and managed at the agency’s Marshall Space Flight Center in Huntsville, Alabama, is exploring applications of large-scale, robotic 3D printing technology for construction on other planets. It sounds like the stuff of science fiction, but demonstrations using simulated lunar and Martian surface material, known as regolith, show the concept could become reality. 
      Lunar 3D printing prototype.Contour Crafting With its partners in industry and academic institutions, MMPACT is developing processing technologies for lunar and Martian construction materials. The binders for these materials, including water, could be extracted from the local regolith to reduce launch mass. The regolith itself is used as the aggregate, or granular material, for these concretes. NASA has evaluated these materials for decades, initially working with large-scale 3D printing pioneer, Dr. Behrokh Khoshnevis, a professor of civil, environmental and astronautical engineering at the University of Southern California in Los Angeles.  
      Khoshnevis developed techniques for large-scale extraterrestrial 3D printing under the NASA Innovative Advanced Concepts (NIAC) program. One of these processes is Contour Crafting, in which molten regolith and a binding agent are extruded from a nozzle to create infrastructure layer by layer. The process can be used to autonomously build monolithic structures like radiation shielding and rocket landing pads. 
      Continuing to work with the NIAC program, Khoshnevis also developed a 3D printing method called selective separation sintering, in which heat and pressure are applied to layers of powder to produce metallic, ceramic, or composite objects which could produce small-scale, more-precise hardware. This energy-efficient technique can be used on planetary surfaces as well as in microgravity environments like space stations to produce items including interlocking tiles and replacement parts. 
      While NASA’s efforts are ultimately aimed at developing technologies capable of building a sustainable human presence on other worlds, Khoshnevis is also setting his sights closer to home. He has created a company called Contour Crafting Corporation that will use 3D printing techniques advanced with NIAC funding to fabricate housing and other infrastructure here on Earth.  
      Another one of NASA’s partners in additive manufacturing, ICON of Austin, Texas, is doing the same, using 3D printing techniques for home construction on Earth, with robotics, software, and advanced material.  
      Construction is complete on a 3D-printed, 1,700-square-foot habitat that will simulate the challenges of a mission to Mars at NASA’s Johnson Space Center in Houston, Texas. The habitat will be home to four intrepid crew members for a one-year Crew Health and Performance Analog, or CHAPEA, mission. The first of three missions begins in the summer of 2023. The ICON company was among the participants in NASA’s 3D-Printed Habitat Challenge, which aimed to advance the technology needed to build housing in extraterrestrial environments. In 2021, ICON used its large-scale 3D printing system to build a 1,700 square-foot simulated Martian habitat that includes crew quarters, workstations and common lounge and food preparation areas. This habitat prototype, called Mars Dune Alpha, is part of NASA’s ongoing Crew Health and Performance Exploration Analog, a series of Mars surface mission simulations scheduled through 2026 at NASA’s Johnson Space Center in Houston.  
      With support from NASA’s Small Business Innovation Research program, ICON is also developing an Olympus construction system, which is designed to use local resources on the Moon and Mars as building materials. 
      The ICON company uses a robotic 3D printing technique called Laser Vitreous Multi-material Transformation, in which high-powered lasers melt local surface materials, or regolith, that then solidify to form strong, ceramic-like structures. Regolith can similarly be transformed to create infrastructure capable of withstanding environmental hazards like corrosive lunar dust, as well as radiation and temperature extremes.  
      The company is also characterizing the gravity-dependent properties of simulated lunar regolith in an experiment called Duneflow, which flew aboard a Blue Origin reusable suborbital rocket system through NASA’s Flight Opportunities program in February 2025. During that flight test, the vehicle simulated lunar gravity for approximately two minutes, enabling ICON and researchers from NASA to compare the behavior of simulant against real regolith obtained from the Moon during an Apollo mission.

Viewers will have the opportunity to provide real-time input to an artist who will create an example of a zero gravity indicator during the livestream. 
      Zero gravity indicators are small, plush items carried aboard spacecraft to provide a visual indication of when the crew reaches space.
      The event will begin at 3 p.m. EDT on Tuesday, May 13, on the agency’s official Twitch channel:
      https://www.twitch.tv/nasa
      The contest invites global creators of all ages to submit design ideas for a zero gravity indicator that will fly aboard the agency’s Artemis II test flight, the first crewed mission under NASA’s Artemis campaign.
      Up to 25 finalists, including entries from a K-12 student division, will be selected. The Artemis II crew will choose one design that NASA’s Thermal Blanket Lab will fabricate to fly alongside the crew in the Orion spacecraft.
      During this Twitch event, NASA experts will discuss the Moon Mascot Challenge while the artist incorporates live audience feedback into a sample design. Although the design example will not be eligible for the contest, it will demonstrate how challenge participants can develop their own zero gravity indicator designs. The example will be shared on the @NASAArtemis social media accounts following the Twitch event.
      The Artemis II test flight will take NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen on a 10-day journey around the Moon and back. The mission is another step toward missions on the lunar surface to help the agency prepare for future human missions to Mars.

      25 Years of NASA Student Launch
      By NASA
      NASA/Charles Beason Students from the University of Massachusetts Amherst team carry their high-powered rocket toward the launch pad at NASA’s 2025 Student Launch launch day competition in Toney, Alabama, on April 4, 2025. More than 980 middle school, high school, and college students from across the nation launched more than 40 high-powered amateur rockets just north of NASA’s Marshall Space Flight Center in Huntsville, Alabama. This year marked the 25th anniversary of the competition.
      To compete, students follow the NASA engineering design lifecycle by going through a series of reviews for nine months leading up to launch day. Each year, a payload challenge is issued to the university teams, and this year’s task focused on communication. Teams were required to have “reports” from STEMnauts, non-living objects inside their rocket, that had to relay real-time data to the student team’s mission control. This Artemis Student Challenge took inspiration from the agency’s Artemis missions, where NASA will send astronauts to explore the Moon for scientific discovery, economic benefit, and to build the foundation for the first crewed missions to Mars.

      NASA Progresses Toward Crewed Moon Mission with Spacecraft, Rocket Milestones
      By NASA
      Technicians move the Orion spacecraft for NASA’s Artemis II test flight out of the Neil A. Armstrong Operations and Checkout Building to the Multi-Payload Processing Facility at Kennedy Space Center in Florida on Saturday, May 3, 2025. NASA/Kim Shiflett Engineers, technicians, mission planners, and the four astronauts set to fly around the Moon next year on Artemis II, NASA’s first crewed Artemis mission, are rapidly progressing toward launch.

      At the agency’s Kennedy Space Center in Florida, teams are working around the clock to move into integration and final testing of all SLS (Space Launch System) and Orion spacecraft elements. Recently they completed two key milestones – connecting the SLS upper stage with the rest of the assembled rocket and moving Orion from its assembly facility to be fueled for flight.

      “We’re extremely focused on preparing for Artemis II, and the mission is nearly here,” said Lakiesha Hawkins, assistant deputy associate administrator for NASA’s Moon to Mars Program, who also will chair the mission management team during Artemis II. “This crewed test flight, which will send four humans around the Moon, will inform our future missions to the Moon and Mars.”
      Teams with NASA’s Exploration Ground Systems Program begin integrating the interim cryogenic propulsion stage to the SLS (Space Launch System) launch vehicle stage adapter on Wednesday, April 30, 2025, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. NASA/Isaac Watson On May 1, technicians successfully attached the interim cryogenic propulsion stage to the SLS rocket elements already poised atop mobile launcher 1, including its twin solid rocket boosters and core stage, inside the spaceport’s Vehicle Assembly Building (VAB). This portion of the rocket produces 24,750 pounds of thrust for Orion after the rest of the rocket has completed its job. Teams soon will move into a series of integrated tests to ensure all the rocket’s elements are communicating with each other and the Launch Control Center as expected. The tests include verifying interfaces and ensuring SLS systems work properly with the ground systems.

      Meanwhile, on May 3, Orion left its metaphorical nest, the Neil Armstrong Operations & Checkout Facility at Kennedy, where it was assembled and underwent initial testing. There the crew module was outfitted with thousands of parts including critical life support systems for flight and integrated with the service module and crew module adapter. Its next stop on the road to the launch pad is the Multi-Payload Processing Facility, where it will be carefully fueled with propellants, high pressure gases, coolant, and other fluids the spacecraft and its crew need to maneuver in space and carry out the mission.

      After fueling is complete, the four astronauts flying on the mission around the Moon and back over the course of approximately 10 days, will board the spacecraft in their Orion Crew Survival System spacesuits to test all the equipment interfaces they will need to operate during the mission. This will mark the first time NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, will board their actual spacecraft while wearing their spacesuits. After the crewed testing is complete, technicians will move Orion to Kennedy’s Launch Abort System Facility, where the critical escape system will be added. From there, Orion will move to the VAB to be integrated with the fully assembled rocket.

      NASA also announced its second agreement with an international space agency to fly a CubeSat on the mission. The collaborations provide opportunities for other countries to work alongside NASA to integrate and fly technology and experiments as part of the agency’s Artemis campaign.

      While engineers at Kennedy integrate and test hardware with their eyes on final preparations for the mission, teams responsible for launching and flying the mission have been busy preparing for a variety of scenarios they could face.

      The launch team at Kennedy has completed more than 30 simulations across cryogenic propellant loading and terminal countdown scenarios. The crew has been taking part in simulations for mission scenarios, including with teams in mission control. In April, the crew and the flight control team at NASA’s Johnson Space Center in Houston simulated liftoff through a planned manual piloting test together for the first time. The crew also recently conducted long-duration fit checks for their spacesuits and seats, practicing several operations while under various suit pressures.
      NASA astronaut Christina Koch participates in a fit check April 18, 2025, in the spacesuit she will wear during Artemis II. NASA/Josh Valcarcel Teams are heading into a busy summer of mission preparations. While hardware checkouts and integration continue, in coming months the crew, flight controllers, and launch controllers will begin practicing their roles in the mission together as part of integrated simulations. In May, the crew will begin participating pre-launch operations and training for emergency scenarios during launch operations at Kennedy and observe a simulation by the launch control team of the terminal countdown portion of launch. In June, recovery teams will rehearse procedures they would use in the case of a pad or ascent abort off the coast of Florida, with launch and flight control teams supporting. The mission management team, responsible for reviewing mission status and risk assessments for issues that arise and making decisions about them, also will begin practicing their roles in simulations. Later this summer, the Orion stage adapter will arrive at the VAB from NASA’s Marshall Spaceflight Center in Huntsville, Alabama, and stacked on top of the rocket.
