The new year of 1969 dawned with optimism that NASA would meet President John F. Kennedy’s goal of landing a man on the Moon and returning him safely to the Earth. The previous year saw four Apollo missions, two uncrewed and two carrying three astronauts each, test different components of the lunar landing architecture, culminating with Apollo 8’s December flight around the Moon. Challenges remaining for the new year included testing the Lunar Module (LM) with a crew, first in Earth orbit, and then in lunar orbit, a flight that served as a dress rehearsal for the Moon landing that could take place on the following mission. With flights occurring every two months, engineers at NASA’s Kennedy Space Center (KSC) in Florida processed three spacecraft and launch vehicles in parallel.

Recovering from the fire

The years 1967 and 1968 proved turbulent for the world. For NASA, the focus remained on recovering from the tragic Apollo 1 fire in time to meet President Kennedy’s fast approaching end of the decade deadline. The fire resulted in a thorough redesign of the Command Module (CM) to reduce flammability risks and to include an easy to open hatch. Engineers also removed flammable materials from the Lunar Module (LM). In November 1967, the first flight of the Saturn V carried Apollo 4 on a nine-hour uncrewed mission to test the CM’s heat shield. Apollo 5 in January 1968 completed an uncrewed test of the LM so successful that NASA decided to cancel a second test. Although fraught with problems, the April 1968 flight of Apollo 6 tested the CM heat shield once again. Managers believed that engineers could solve the problems encountered during this mission and declared that the next Saturn V would carry a crew.

Apollo 7 and 8

By October 1968, thorough ground testing of the Apollo spacecraft enabled the first crewed mission since the fire. Apollo 7 astronauts Walter M. Schirra, Donn F. Eisele, and R. Walter Cunningham successfully completed the 11-day test flight, achieving all mission objectives. In August, with LM development running behind schedule, senior NASA managers began discussions of sending Apollo 8 on a circumlunar flight, pending the outcome of Apollo 7. With that hurdle successfully cleared, astronauts Frank Borman, James A. Lovell, and William A. Anders orbited the Moon 10 times during Christmas 1968, taking a giant leap toward achieving the Moon landing.

With their space missions completed, the Apollo 7 and 8 crews remained busy with events celebrating their successes. On Jan. 3, 1969, TIME magazine named Apollo 8 astronauts Borman, Lovell, and Anders their Men of the Year for 1968. Kicking off a whirlwind of events, on Jan. 9, outgoing President Lyndon B. Johnson welcomed them to the White House, where he presented them with NASA Distinguished Service Medals. They in turn presented him with a copy of the famous Earthrise photograph. Accompanied by Vice President Hubert H. Humphrey, Borman, Lovell, and Anders rode in a motorcade down Pennsylvania Avenue to the Capitol where the astronauts addressed a joint meeting of Congress. From there, they proceeded to the State Department for a press conference, their day ending with a dinner in their honor at the Smithsonian Institution.

On Jan. 10, New York City held a tickertape parade for Borman, Lovell, and Anders. Mayor John V. Lindsay presented them with Medals of the City of New York, after which they attended a luncheon at Lincoln Center, a reception at the United Nations, and dinner at the Waldorf-Astoria Hotel. The next day, in 15-degree weather, they spoke to a crowd of about 1,500 people at Newark Airport before boarding a plane for much warmer Miami, where on Jan. 12 they attended Super Bowl III, and led the Orange Bowl crowd in reciting the Pledge of Allegiance.

A crowd estimated at about 250,000 welcomed Borman, Lovell, and Anders home to Houston on Jan. 13. In a ceremony outside the Albert Thomas Convention Center, Mayor Louie Welch presented them with bronze medals for heroism, and the astronauts presented Welch and Texas Governor John B. Connally with plaques bearing Texas flags they had flown to the Moon as well as a framed copy of the Earthrise photograph. The astronauts took part in the largest parade in the city’s history. The next day, the city of Chicago welcomed Borman, Lovell, and Anders. An estimated 1.5 million people cheered them on their parade route to a reception where they received honors from city council.

On Jan. 20, Apollo 7 astronauts Schirra, Eisele, and Cunningham rode in President Richard M. Nixon’s inauguration parade in Washington, D.C. Their spacecraft and a LM mockup rode on a float behind them. Ten days later, the new President invited Apollo 8 astronauts Borman, Lovell, and Anders to the White House where he announced that Borman and his family would embark on an 18-day goodwill tour of eight European nations, starting on Feb. 2.

Apollo 9

The LM remained the one component of the lunar landing architecture not yet tested by astronauts in space. That task fell to James A. McDivitt, David R. Scott, and Russell L. Schweickart, the crew of Apollo 9. They and their backups Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean spent many hours in the LM simulators and training for the spacewalk component of the mission.

Apollo 9’s 10-day mission would take place in the relative safety of low Earth orbit. After docking with the LM, the crew’s first major task involved the first spacewalk of the Apollo program and the only in-space test of the new A7L spacesuit before the Moon landing. McDivitt and Schweickart planned to enter the LM, leaving Scott in the CM. Schweickart and Scott would each perform a spacewalk from their respective spacecraft. Scott would only stand in the open CM hatch while Schweickart would exit via the LM’s front hatch onto its porch, translate over to the CM using handrails, retrieve materials samples mounted on the spacecraft’s exterior and return back to the LM, spending two hours outside. This spacewalk tested the ability of crews to transfer through open space, in case a malfunction with the tunnel or hatches between the two spacecraft prevented an internal transfer. The day after the spacewalk, McDivitt and Schweickart planned to undock the LM, leaving Scott in the CM, fly it up to 100 miles away, testing its descent and ascent stages before returning to Scott in the CM who would perform the rendezvous and docking.

The first of the three vehicles in processing flow at KSC, Apollo 9 rolled out from High Bay 3 of the Vehicle Assembly Building (VAB) to Launch Pad 39A on Jan. 3, just 13 days after Apollo 8 launched from the same facility, causing relatively minor damage. Stages of the Apollo 9 Saturn V had arrived at KSC during the spring and summer of 1968, the LM arrived in June and the Command and Service Modules (CSM) in October. Workers completed stacking of the Saturn V in October, adding the Apollo spacecraft in early December. On Jan. 8, NASA announced Feb. 28, 1969, as the planned launch date for Apollo 9.

Workers at the pad immediately began to prepare the vehicle for flight, including software integration tests with the Mission Control Center at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. On Jan. 15, the prime and backup crews conducted emergency egress training from their spacecraft at Launch Pad 39A. Launch controllers at KSC successfully completed the Flight Readiness Test, the final major overall test of the vehicle’s systems, between Jan. 19 and 22. During a Jan. 25 press conference at the Grumman Aircraft and Engineering Corporation in Bethpage, New York, manufacturer of the LM, the Apollo 9 astronauts provided reporters with an overview of their mission.

Apollo 10

Assuming Apollo 9 met its objectives and the LM proved space worthy in Earth orbit, in May Apollo 10 would repeat many of those tests in lunar orbit, including flying to within nine miles of the Moon’s surface.

In November 1968, just six months before the planned launch date, NASA officially named the Apollo 10 crew. The prime crew consisted of Thomas P. Stafford, John W. Young, and Eugene A. Cernan. All had flown Gemini missions and had recently served as the Apollo 7 backup crew. L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell served as their backups.

In the VAB’s High Bay 2, workers had completed stacking the Apollo 10 Saturn V’s three stages by the final days of 1968, while their colleagues prepared to roll Apollo 9’s rocket to the pad a few days later. In the nearby Manned Spacecraft Operations Building (MSOB), prime and backup crews completed altitude tests of the LM in December and workers conducted a docking test between the LM and the CM. On Jan. 16, Stafford, Young, and Cernan completed their altitude test of the CM, followed by Cooper, Eisele, and Mitchell the next day. Workers removed the spacecraft from the altitude chamber in preparation for its rollover to the VAB in early February for stacking onto the rocket.

Apollo 11

Assuming Apollo 9 and 10 accomplished their objectives, Apollo 11 would attempt the first Moon landing in July. Should Apollo 11 not succeed, NASA would try again with Apollo 12 in September and even Apollo 13 in November or December. Spacecraft and rocket manufacturers continued building components to meet that aggressive schedule.

On Jan. 9, a mere six months before the planned launch date, NASA formally announced the Apollo 11 crew, the second all-veteran three-person crew after Apollo 10 – and the last all-veteran crew until STS-26 in 1988. The next day, NASA introduced the Apollo 11 crew during a press conference at MSC. The prime crew consisted of Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin. Each astronaut had flown one Gemini mission. Armstrong and Aldrin had served on the backup crew for Apollo 8 while Collins was initially a member of the prime Apollo 8 crew until a bone spur in his neck requiring surgery sidelined him. He fully recovered from the operation, and NASA included him in the Apollo 11 crew. The Apollo 11 backup crew consisted of James A. Lovell, William A. Anders, and Fred W. Haise. Lovell and Anders had just completed the Apollo 8 lunar orbit mission with Haise a backup crew member on that flight. When Anders announced that he would retire from NASA in August 1969 to join the National Space Council, Thomas K. “Ken” Mattingly began training in parallel with Anders in case the mission slipped past that date.

Hardware began to arrive at KSC for Apollo 11. With the Apollo 10 CSM still undergoing testing in the MSOB, the Apollo 11 LM’s ascent and descent stages arrived Jan. 8 and 12, respectively, followed by the CM and SM on Jan. 23. Workers in the MSOB prepared the spacecraft for vacuum chamber testing. The Saturn V’s S-IVB third stage arrived on Jan. 19. Workers trucked it to the VAB where it awaited the arrival of the first two stages, scheduled for February.

With the Moon landing possibly just six months away, NASA continued to prepare key facilities designed to receive astronauts returning from the Moon. The 83,000-square-foot Lunar Receiving Laboratory (LRL), residing in MSC’s Building 37, was specially designed and built to isolate the astronauts, their spacecraft, and lunar samples to prevent back-contamination of the Earth by any possible lunar micro-organisms, and to maintain the lunar samples in as pristine a condition as possible. The building was completed in 1967, and over the next year, workers outfitted its laboratories and other facilities. A 10-day simulation in the facility in November 1968 found some deficiencies that NASA addressed promptly. On Jan. 23, 1969, workers brought a mockup Apollo CM into the LRL’s spacecraft storage area for fit checks.

An integral component of the back-contamination prevention process was the Mobile Quarantine Facility (MQF). Following lunar landing missions, the MQF housed astronauts and support personnel from their arrival onboard the prime recovery ship shortly after splashdown through transport to the LRL. Under contract to NASA, Melpar, Inc., of Falls Church, Virginia, converted four 35-foot Airstream trailers into MQFs, delivering the first unit in March 1968 and the last three in the spring of 1969. The first unit was used extensively for testing, with lessons learned incorporated into the later models. On Jan. 21, 1969, workers loaded the MQF aboard a U.S. Air Force C-141 cargo plane at Ellington Air Force Base near MSC to transport it to the Norfolk Naval Air Station in Virginia. Six recovery specialists from MSC spent 10 days inside the MQF, first aboard the helicopter landing-platform USS Guadalcanal (LPH-7), including attaching a flexible tunnel to a boilerplate Apollo CM, and then aboard the destroyer USS Fox (DLG-33). The overall exercise, successfully completed on Feb. 3, tested all MQF systems aboard ships and aircraft to simulate recovery operations after a lunar landing mission.

      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.
