Preparations for Next Moonwalk Simulations Underway (and Underwater)
Ahead of launch, NASA’s SPHEREx is enclosed in a payload fairing at Vandenberg Space Force Base on March 2. The observatory is stacked atop the four small satellites that make up the agency’s PUNCH mission.NASA/BAE Systems/Benjamin Fry NASA’s latest space observatory is targeting a March 8 liftoff, and the agency’s PUNCH heliophysics mission is sharing a ride. Here’s what to expect during launch and beyond.
In a little over a day, NASA’s SPHEREx space telescope is slated to launch from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. The observatory will map the entire celestial sky four times in two years, creating a 3D map of over 450 million galaxies. In doing so, the mission will provide insight into what happened a fraction of a second after the big bang, in addition to searching interstellar dust for the ingredients of life, and measuring the collective glow from all galaxies, including ones that other telescopes cannot easily detect.
The launch window opens at 7:09:56 p.m. PST on Saturday, March 8, with a target launch time of 7:10:12 p.m. PST. Additional opportunities occur in the following days.
Launching together into low Earth orbit, NASA’s SPHEREx and PUNCH missions will study a range of topics from the early universe to our nearest star. NASA/JPL-Caltech Sharing a ride with SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere), a constellation of four small satellites that will map the region where the Sun’s outer atmosphere, the corona, transitions to the solar wind, the constant outflow of material from the Sun.

What SPHEREx Will Do
The SPHEREx observatory detects infrared light — wavelengths slightly longer than what the human eye can see that are emitted by warm objects including stars and galaxies. Using a technique called spectroscopy, SPHEREx will separate the infrared light emitted by hundreds of millions of stars and galaxies into 102 individual colors — the same way a prism splits sunlight into a rainbow. Observing those colors separately can reveal various properties of objects, including their composition and, in the case of galaxies, their distance from Earth. No other all-sky survey has performed spectroscopy in so many wavelengths and on so many sources.
The mission’s all-sky spectroscopic map can be used for a wide variety of science investigations. In particular, SPHEREx has its sights set on a phenomenon called inflation, which caused the universe to expand a trillion-trillionfold in a fraction of a second after the big bang. This nearly instantaneous event left an impression on the large-scale distribution of matter in the universe. The mission will map the distribution of more than 450 million galaxies to improve scientists’ understanding of the physics behind this extreme cosmic event.
SPHEREx Fact Sheet Additionally, the space telescope will measure the total glow from all galaxies, including ones that other telescopes cannot easily detect. When combined with studies of individual galaxies by other telescopes, the measurement of this overall glow will provide a more complete picture of how the light output from galaxies has changed over the universe’s history.
At the same time, spectroscopy will allow SPHEREx to seek out frozen water, carbon dioxide, and other key ingredients for life. The mission will provide an unprecedented survey of the location and abundance of these icy compounds in our galaxy, giving researchers better insight into the interstellar chemistry that set the stage for life.
Launch Sequence
But, first, SPHEREx has to get into space. Prelaunch testing is complete on the spacecraft’s various systems, and it’s been encapsulated in the protective nose cone, or payload fairing, atop the SpaceX Falcon 9 rocket that will get it there from Vandenberg’s Space Launch Complex-4 East.
NASA’s SPHEREx mission will lift off from Space Launch Complex-4 East at Vanden-berg Space Force Base in California aboard a SpaceX Falcon 9 rocket, just as the Sur-face Water and Ocean Topography mission, shown here, did in December 2022. NASA/Keegan Barber A little more than two minutes after the Falcon 9 lifts off, the main engine will cut off. Shortly after, the rocket’s first and second stages will separate, followed by second-stage engine start. The reusable first stage will then begin its automated boost-back burn to the launch site for a propulsive landing.
Once the rocket is out of Earth’s atmosphere, about three minutes after launch, the payload fairing that surrounds the spacecraft will separate into two halves and fall back to Earth, landing in the ocean. Roughly 41 minutes after launch, SPHEREx will separate from the rocket and start its internal systems so that it can point its solar panel to the Sun. After this happens, the spacecraft can establish communications with ground controllers at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission for the agency. This milestone, called acquisition of signal, should happen about three minutes after separation.
About 52 minutes after liftoff, PUNCH should separate as well from the Falcon 9.
Both spacecraft will be in a Sun-synchronous low Earth orbit, where their position relative to the Sun remains the same throughout the year. Each approximately 98-minute orbit allows the SPHEREx telescope to view a 360-degree strip of the celestial sky. As Earth’s orbit around the Sun progresses, that strip slowly advances, enabling SPHEREx to image almost the entire sky in six months. For PUNCH, the orbit provides a clear view in all directions around the Sun.
About four days after launch, SPHEREx should eject the protective cover over its telescope lens. The observatory will begin science operations a little over a month after launch, once the telescope has cooled down to its operating temperature and the mission team has completed a series of checks.
NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, is providing the launch service for SPHEREx and PUNCH.

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side about 820 feet from the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Credit: Intuitive Machines Shortly after touching down inside a crater on the Moon, carrying NASA technology and science on its IM-2 mission, Intuitive Machines collected some data for the agency before calling an early end of mission at 12:15 a.m. CST Friday.
As part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the IM-2 mission included a drill to bring lunar soil to the surface and a mass spectrometer to look for the presence of volatiles, or gases, that could one day help provide fuel or breathable oxygen to future Artemis explorers.
Planned to land at Mons Mouton, IM-2 touched down at approximately 11:30 a.m. March 6, more than 1,300 feet (400 meters) from its intended landing site. Intuitive Machines said images collected later confirmed the lander was on its side, preventing it from fully operating the drill and other instruments before its batteries were depleted.
The IM-2 mission landed closer to the lunar South Pole than any previous lander.
“Our targeted landing site near the lunar South Pole is one of the most scientifically interesting, and geographically challenging locations, on the Moon,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “Each success and setback are opportunities to learn and grow, and we will use this lesson to propel our efforts to advance science, exploration, and commercial development as we get ready for human exploration of Mars.”
The Nova-C lander, named Athena, captured and transmitted images of the landing site before activating the technology and science instruments. Among the data collected, NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) suite, which includes the lunar drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), successfully demonstrated the hardware’s full range of motion in the harsh environment of space. The Mass Spectrometer Observing Lunar Operations (MSOLO) as part of the PRIME-1 suite of instruments, detected elements likely due to the gases emitted from the lander’s propulsion system.
“While this mission didn’t achieve all of its objectives for NASA, the work that went into the payload development is already informing other agency and commercial efforts,” said Clayton Turner, associate administrator for space technology, NASA Headquarters. “As we continue developing new technologies to support exploration of the Moon and Mars, testing technologies in-situ is crucial to informing future missions. The CLPS initiative remains an instrumental method for achieving this.”
Despite the lander’s configuration, Intuitive Machines, which was responsible for launch, delivery, and surface operations under its CLPS contract, was able to complete some instrument checkouts and collect 250 megabytes of data for NASA.
“Empowering American companies to deliver science and tech to the Moon on behalf of NASA both produces scientific results and continues development of a lunar economy,” said Joel Kearns, deputy associate administrator for Exploration in the Science Mission Directorate at NASA Headquarters. “While we’re disappointed in the outcome of the IM-2 mission, we remain committed to supporting our commercial vendors as they navigate the very difficult task of landing and operating on the Moon.”
NASA’s Laser Retroreflector Array, a passive instrument meant to provide a reference point on the lunar surface and does not power on, will remain affixed to the top deck of the lander. Although Intuitive Machines’ Nova-C Hopper and Nokia’s 4G/LTE Tipping Point technologies, funded in part by NASA, were only able to complete some objectives, they provided insight into maturing technologies ready for infusion into a commercial space application including some checkouts in flight and on the surface.
Intuitive Machines’ IM-2 mission launched at 6:16 p.m., Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
Intuitive Machines has two more deliveries on the books for NASA in the future, with its IM-3 mission slated for 2026, and IM-4 mission in 2027.
To date, five vendors have been awarded a total of 11 lunar deliveries under CLPS and are sending more than 50 instruments to various locations on the Moon, including the Moon’s far side and South Pole region. CLPS contracts are indefinite-delivery/indefinite-quantity contracts with a cumulative maximum contract value of $2.6 billion through 2028.

Credit: NASA NASA is seeking design ideas from global creators for a zero gravity indicator that will fly aboard the agency’s Artemis II test flight. Zero gravity indicators are small, plush items carried aboard spacecraft to provide a visual indication of when the spacecraft and its crew reach space.
This opportunity, with a submission deadline of May 27, asks for original designs representing the significance of NASA’s Artemis campaign, the mission, or exploration and discovery, and meet specific requirements for materials and size.
“What better way to fly a mission around the Moon than to invite the public inside NASA’s Orion spacecraft with us and ask for help in designing our zero gravity indicator?” asked Reid Wiseman, NASA astronaut and Artemis II commander, at the agency’s Johnson Space Center in Houston. “The indicator will float alongside Victor, Christina, Jeremy, and me as we go around the far side of the Moon and remind us of all of you back on Earth.”
Up to 25 finalists, including 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 them in Orion. Imagine seeing your creation floating weightlessly with astronauts on their way around the Moon.
For complete contest details, visit:
http://www.freelancer.com/moon-mascot
Crowdsourcing company Freelancer is hosting the challenge, called Moon Mascot: NASA Artemis II ZGI Design Contest, on behalf of the agency through the NASA Tournament Lab, managed by the agency’s Space Technology Mission Directorate.
NASA has a long history of flying zero gravity indicators for human spaceflight missions. Many missions to the International Space Station include a plush item. A plush Snoopy rode inside Orion during NASA’s uncrewed Artemis I mission.
Artemis II will be the first test flight of the Space Launch System rocket, Orion spacecraft, and supporting ground system with crew aboard. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen will venture around the Moon and back. The mission is the first crewed flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.
All major elements for Artemis II are readying for flight. Engineers recently completed stacking the twin solid rocket boosters for the SLS (Space Launch System) on their launch platform and are preparing for integration of the SLS core stage in the coming weeks. Teams also recently installed the solar array wings on the Orion spacecraft that will carry the four astronauts on their journey around the Moon and home.
Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

NASA’s SpaceX Crew-9 mission with agency astronauts Nick Hague, Butch Wilmore, and Suni Williams, and Roscosmos cosmonaut Aleksandr Gorbunov is preparing to return to Earth following their science mission aboard the International Space Station. Hague, Williams, and Wilmore completed more than 900 hours of research between over 150 unique scientific experiments and technology demonstrations during their stay aboard the orbiting laboratory.
Here’s a look at some scientific milestones accomplished during their journey:
Mighty microalgae
NASA astronaut Nick Hague processes samples for Arthrospira C, an investigation from ESA (European Space Agency) that transplants and grows Arthrospiramicro-algae eboard the International Space Station. These organisms conduct photosynthesis and could be used to convert carbon dioxide exhaled by crew members into oxygen, helping maintain a safe atmosphere inside spacecraft. Arthrospira also could provide fresh food on long-duration space missions.
NASA Improving astronaut exercise
Researchers are testing the European Enhanced Exploration Exercise Device (E4D), a modular device that combines cycling, rowing, and resistance exercises to help keep crews healthy on long-duration missions. A single, small device effective at countering bone and muscle loss and improving cardiovascular health is needed for use on future spacecraft such as the Gateway lunar space station. NASA astronaut Butch Wilmore works on installing the device aboard the International Space Station ahead of its evaluation.
NASA Watering the garden
This red romaine lettuce growing in the International Space Station’s Advanced Plant Habitat is part of Plant Habitat-07, a study of how different moisture levels affect the microbial communities in plants and water. Results could show how less-than-ideal conditions affect plant growth and help scientists design systems to produce safe and nutritious food for crew members on future space journeys.
NASA Packing it in
Packed bed reactors are systems that “pack” materials such as pellets or beads inside a structure to increase contact between any liquids and gasses flowing through it. NASA astronaut Suni Williams installs hardware for the Packed Bed Reactor Experiment: Water Recovery Series (PBRE-WRS) investigation, which examines how gravity affects these systems aboard the International Space Station. Results could help scientists design better reactors for water recovery, thermal management, fuel cells, and other applications.
NASA Fueling the flames
During the Residence Time Driven Flame Spread (SOFIE-RTDFS) investigation at the International Space Station, this sheet of clear acrylic plastic burns at higher oxygen levels and half the standard pressure of Earth’s atmosphere. From left to right, the image sequence shows a side and top view of the fuel and the oxygen slowly diffusing into the flame. Studying the spread of flames in microgravity could help improve safety on future missions.
NASA Monitoring microbes in space
During a recent spacewalk, NASA astronaut Butch Wilmore swabbed the exterior of the International Space Station for ISS External Microorganisms, an investigation exploring whether microorganisms leave the spacecraft through its vents and, if so, which ones survive. Humans carry microorganisms along with them wherever they go, and this investigation could help scientists take steps to limit microbial spread to places like the Moon and Mars.
NASA A hearty workout
NASA astronaut Nick Hague exercises on the International Space Station’s Advanced Resistive Exercise Device while wearing the Bio-Monitor vest and headband. This set of garments contains sensors that unobtrusively collect data such as heart rate, breathing rate, blood pressure, and temperature. The data supports studies on human health, including Vascular Aging, a CSA (Canadian Space Agency) investigation that monitors cardiovascular function in space.
NASA On-demand medical devices
NASA astronaut Butch Wilmore works with hardware for InSPA Auxilium Bioprinter, a study that tests 3D printing of an implantable medical device that could facilitate recovery from peripheral nerve damage, a type of injury that can cause sensory and motor issues. In microgravity, this manufacturing technique produces higher-quality devices that may perform better, benefitting crew members on future long-duration missions and patients back home.
NASA Could wood be better
A deployer attached to the International Space Station’s Kibo laboratory module launches LignoSat into space. JAXA (Japan Aerospace Exploration Agency) developed the satellite to test using wood as a more sustainable alternative to conventional satellite materials. Researchers previously exposed different woods to space and chose magnolia as the best option for the study, including sensors to evaluate the wood’s strain and its response to temperature and radiation. Researchers also are monitoring whether Earth’s geomagnetic field interferes with the satellite’s data transmission.
NASA Making microbes in space
NASA astronaut Suni Williams poses with bacteria and yeast samples for Rhodium Biomanufacturing 03, part of an ongoing examination of microgravity’s effects on biomanufacturing engineered bacteria and yeast aboard the International Space Station. Microgravity causes changes in microbial cell growth, cell structure, and metabolic activity that can affect biomanufacturing processes. This investigation could clarify the extent of these effects and advance the use of microbes to make food, pharmaceuticals, and other products in space, reducing the cost of launching equipment and consumables from Earth.
NASA A NICER spacewalk
The International Space Station’s Neutron star Interior Composition Explorer, or NICER, studies neutron stars, the glowing cinders left behind when massive stars explode as supernovas. NASA astronaut Nick Hague installs patches during a spacewalk to repair damage to thermal shields that block out sunlight while allowing X-rays to pass through the instrument. NICER continues to generate trailblazing astrophysics discoveries reported in hundreds of scientific papers.
NASA Earth from every angle
From inside the International Space Station’s cupola, NASA astronaut Butch Wilmore photographs landmarks on Earth approximately 260 miles (418 kilometers) below. Crew members have taken millions of images of Earth from the space station for Crew Earth Observations, creating one of the longest-running records of how our planet changes over time. These images support a variety of research, including studies of phenomena such as flooding and fires, atmospheric processes affected by volcanic eruptions, urban growth, and land use.
NASA An out-of-this-world sunrise
This photograph captures an orbital sunrise above the lights of Rio de Janeiro and Sao Paulo as the International Space Station orbits above Brazil. This image is one of the millions of photographs taken by crew members for Crew Earth Observations. These images teach us more about our home planet, and studies show that taking them improves the mental well-being of crew members. Many spend much of their free time pursuing shots that, like this one, are only possible from space.
NASA Vital vitamins
The BioNutrients investigation demonstrates technology to produce nutrients during long-duration space missions using engineered microbes like yeast. Food stored for long periods can lose vitamins and other nutrients, and this technology could provide a way to make supplements on demand. NASA astronaut Suni Williams prepares specially designed growth packets for the investigation aboard the International Space Station.
NASA Blowing in the solar wind
The International Space Station’s robotic hand, Dextre, attached to the Canadarm2 robotic arm, moves hardware into position for the COronal Diagnostic EXperiment, or CODEX. This investigation examines solar wind and how it forms using a solar coronagraph, which blocks out bright light from the Sun to reveal details in its outer atmosphere or corona. Results could help scientists understand the heating and acceleration of the solar wind and provide insight into the source of the energy that generates it.
NASA Can you hear me now?
Roscosmos cosmonaut Aleksandr Gorbunov conducts a hearing test in the relative quiet of the International Space Station’s Quest airlock. Crew members often serve as test subjects for research on how spaceflight affects hearing and vision, the immune and cardiovascular systems, and other bodily functions. This research supports the development of ways to prevent or mitigate these effects.
NASA Exposing materials to space
Euro Material Ageing, an ESA (European Space Agency) investigation, studies how certain materials age when exposed to the harsh space environment. Findings could advance design for spacecraft and satellites, including improved thermal control, as well as the development of sensors for research and industrial applications. NASA astronaut Suni Williams installs the experiment into the Nanoracks Bishop airlock for transport to the outside of the International Space Station.
NASA Sending satellites into space
NASA astronauts Don Pettit and Butch Wilmore remove a small satellite deployer from an airlock on the International Space Station. The deployer had released several CubeSats into Earth orbit including CySat-1, a remote sensor that measures soil moisture, and DORA, a receiver that could provide affordable and accurate communications among small spacecraft.
NASA Robotic relocation
The Responsive Engaging Arms for Captive Care and Handling demonstration (Astrobee REACCH) uses the International Space Station’s Astrobee robots to test technology for capturing objects of any geometry or material orbiting in space. This ability could enable satellite servicing and movement to maximize the lifespan of these tools and removal of space debris that could damage satellites providing services to the people of Earth. NASA astronaut Suni Williams checks out an Astrobee fitted with tentacle-like arms and adhesive pads for the investigation.
NASA Arms to hold
As part of a program called High school students United with NASA to Create Hardware, or HUNCH, NASA astronaut Nick Hague demonstrates the HUNCH Utility Bracket, a student-designed tool to hold and position cameras, tablets, and other equipment that astronauts use daily. Currently, crew members on the International Space Station use devices called Bogen Arms, which have experienced wear and tear and need to be replaced.
NASA A Dragon in flight
The SpaceX Dragon spacecraft fires its thrusters after undocking from the International Space Station as it flies 260 miles (418 kilometers) above the Pacific Ocean west of Hawaii. NASA’s commercial resupply services deliver critical scientific studies, hardware, and supplies to the station.
