From left are: Jeremy Hansen, mission specialist; Victor Glover, pilot; Reid Wiseman, commander; and Christina Hammock Koch, mission specialist.

On NASA’s upcoming Artemis II mission, four astronauts will fly inside the Orion spacecraft and venture around the Moon, becoming the first to lay their eyes on our celestial neighbor at a relatively close distance in more than 50 years.

Orion will be home for NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and Canadian Space Agency (CSA) astronaut Jeremy Hansen during their 600,000-mile, nearly 10-day journey. They will live and work in Orion’s crew module while its service module provides the essential commodities astronauts need to stay alive, including potable water and nitrogen and oxygen to breathe.

As the first time astronauts will fly aboard Orion, Artemis II will include several objectives to check out many of the spacecraft’s life support systems operating in space for the first time. The crew will provide valuable feedback for future Artemis missions to the Moon.

Spacecraft Life

Orion’s cabin has a habitable volume of 330 cubic feet, giving the crew about as much living space as two minivans. After their ride to space atop NASA’s SLS (Space Launch System) rocket, the crew will stow Koch and Hansen’s seats until the day of return, giving them more room to move around during the flight. The backs of Wiseman and Glover’s seats, as commander and pilot respectively, will remain out but their foot pans will be stowed. Orion has nearly 60 percent more space than the Apollo command module’s 210 cubic feet.

What’s on the Menu?

Food scientists in the Space Food Systems Laboratory at the agency’s Johnson Space Center in Houston are working with the crew to pre-select their meals long before departing Earth. While they won’t have the day-to-day options that a space station crew has during their expeditions, the Artemis II astronauts will have a set menu based on their personal preferences and nutritional needs. Orion is outfitted with a water dispenser and food warmer to rehydrate and heat food, and the crew will have dedicated meal times in their schedule to refuel.

Fit for Flight

Each astronaut will dedicate 30 minutes daily to exercise, minimizing the muscle and bone loss that occurs without gravity. Orion is equipped with a flywheel, a small device installed directly below the side hatch used to enter and exit Orion and will conveniently be used as a step when the crew get inside Orion on launch day. The flywheel is a simple cable-based device for aerobic exercises like rowing and resistance workouts like squats and deadlifts. It works like a yo-yo, giving astronauts as much load as they put into it, maxing out at 400 pounds.

On the International Space Station, astronauts have several exercise machines that collectively weigh more than 4,000 pounds and occupy about 850 cubic feet. While effective for space station crew members, Orion’s exercise equipment must accommodate more stringent mass and volume constraints. The flywheel weighs approximately 30 pounds and is slightly smaller than a carry-on suitcase.

Keeping it Clean

The hygiene bay includes doors for privacy, a toilet, and space for the crew to bring in their personal hygiene kits. The kits typically include items like a hairbrush, toothbrush and toothpaste, soap, and shaving supplies. Astronauts can’t shower in space but use liquid soap, water, and rinseless shampoo to remain clean.

When nature inevitably comes calling, crew members will use Orion’s toilet, the Universal Waste Management System, a feature Apollo crews did not have. Nearly identical to a version flying on  NASA’s space station, the system collects urine and feces separately. Urine will be vented overboard while feces are collected in a can and safely stowed for disposal upon return.

Should the toilet malfunction, the crew will be able to use collapsible contingency urinals, a system that collects urine in a bag and interfaces with the venting system to send the urine overboard. With two different styles designed to accommodate both females and males, the bags hold about a liter of urine each. Should the UWMS fail, the crew will still use the toilet for fecal collection, only without the fan that helps with fecal separation.

A team member at Johnson Space Center in Houston demonstrates lifting the urine hose of the Universal Waste Management System out of its cradled position like a crew member would for use. A funnel (not shown) is attached to the open end of this hose and can then be easily replaced or removed for disinfection. 

Medical Care

In case of minor medical needs during the mission, Orion will have a medical kit on board that includes everything from basic first aid items to diagnostic tools, such as a stethoscope and an electrocardiogram, that can be used to provide data to physicians on the ground. The crew will also have regular private medical conferences with flight surgeons in mission control to discuss their health and well-being.

Catching Some Shuteye

With a jam-packed schedule, the Artemis II crew will have a full eight hours of sleep built into their schedule to ensure they’re well rested and can make the most of their mission. For most of the mission, all four crew will sleep at the same time, attaching sleeping bags to Orion’s walls for some shuteye.

Artemis II crew sleeping bag configurations are tested in the Orion spacecraft medium-fidelity mockup at NASA’s Johnson Space Center in Houston, used for astronaut training and systems familiarization.

Keeping in Touch

Inside Orion, the astronauts will use a handheld microphone and speaker or wear a headset to communicate with mission controllers, conduct medical checks with flight physicians, and catch up with their families. The crew will also have tablets and laptops they can use to review procedures and load entertainment onto before launch.

Artemis II will confirm all Orion’s systems operate as designed with crew aboard in the actual environment of deep space. The mission will pave the way for future lunar surface missions, including by the first woman and first person of color, establishing long-term lunar science and exploration capabilities, and inspire the next generation of explorers – The Artemis Generation.

      Teams with NASA are gaining momentum as work progresses toward future lunar missions for the benefit of humanity as numerous flight hardware shipments from across the world arrived at the agency’s Kennedy Space Center in Florida for the first crewed Artemis flight test and follow-on lunar missions. The skyline at Kennedy will soon see added structures as teams build up the ground systems needed to support them.
      Crews are well underway with parallel preparations for the Artemis II flight, as well as buildup of NASA’s mobile launcher 2 tower for use during the launch of the SLS (Space Launch System) Block 1B rocket, beginning with the Artemis IV mission. This version of NASA’s rocket will use a more powerful upper stage to launch with crew and more cargo on lunar missions. Technicians have begun upper stage umbilical connections testing that will help supply fuel and other commodities to the rocket while at the launch pad.
      In summer 2024, technicians from NASA and contractor Bechtel National, Inc. completed a milestone called jack and set, where the center’s mega-mover, the crawler transporter, repositioned the initial steel base assembly for mobile launcher 2 from temporary construction shoring to its six permanent pedestals near the Kennedy’s Vehicle Assembly Building.   
      Teams at Bechtel National, Inc. use a crane to lift Module 4 into place atop the mobile launcher 2 tower chair at its park site on Jan. 3, 2025, at Kennedy Space Center in Florida. Module 4 is the first of seven modules that will be stacked vertically to make up the almost 400-foot launch tower that will be used beginning with the Artemis IV mission.Betchel National Inc./Allison Sijgers “The NASA Bechtel mobile launcher 2 team is ahead of schedule and gaining momentum by the day,” stated Darrell Foster, ground systems integration manager, NASA’s Exploration Ground Systems Program at NASA Kennedy. “In parallel to all of the progress at our main build site, the remaining tower modules are assembled and outfitted at a second construction site on center.”
      As construction of the mobile launcher 2’s base continues, the assembly operations shift into integration of the modules that will make up the tower. In mid-October 2024, crews completed installation of the chair, named for its resemblance to a giant seat. The chair serves as the interface between the base deck and the vertical modules which are the components that will make up the tower, and stands at 80-feet-tall.
      In December 2024, teams completed the rig and set Module 4 operation where the first of a total of seven 40-foot-tall modules was stacked on top of the chair. Becthel crews rigged the module to a heavy lift crane, raised the module more than 150-feet, and secured the four corners to the tower chair. Once complete, the entire mobile launcher structure will reach a height of nearly 400 feet – approximately the length of four Olympic-sized swimming pools placed end-to-end.
      On the opposite side of the center, test teams at the Launch Equipment Test Facility are testing the new umbilical interfaces, which will be located on mobile launcher 2, that will be needed to support the new SLS Block 1B Exploration Upper Stage. The umbilicals are connecting lines that provide fuel, oxidizer, pneumatic pressure, instrumentation, and electrical connections from the mobile launcher to the upper stage and other elements of SLS and NASA’s Orion spacecraft.
      “All ambient temperature testing has been successfully completed and the team is now beginning cryogenic testing, where liquid nitrogen and liquid hydrogen will flow through the umbilicals to verify acceptable performance,” stated Kevin Jumper, lab manager, NASA Launch Equipment Test Facility at Kennedy. “The Exploration Upper Stage umbilical team has made significant progress on check-out and verification testing of the mobile launcher 2 umbilicals.”
      https://www.nasa.gov/wp-content/uploads/2025/01/eusu-test-3-5b-run-1.mp4 Exploration Upper Stage Umbilical retract testing is underway at the Launch Equipment Test Facility at Kennedy Space Center in Florida on Oct. 22, 2024. The new umbilical interface will be used beginning with the Artemis IV mission. Credit: LASSO Contract LETF Video Group The testing includes extension and retraction of the Exploration Upper Stage umbilical arms that will be installed on mobile launcher 2. The test team remotely triggers the umbilical arms to retract, ensuring the ground and flight umbilical plates separate as expected, simulating the operation that will be performed at lift off.

      Pandora, NASA’s newest exoplanet mission, is one step closer to launch with the completion of the spacecraft bus, which provides the structure, power, and other systems that will enable the mission to carry out its work.
      Watch to learn more about NASA’s Pandora mission, which will revolutionize the study of exoplanet atmospheres.
      NASA’s Goddard Space Flight Center “This is a huge milestone for us and keeps us on track for a launch in the fall,” said Elisa Quintana, Pandora’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The bus holds our instruments and handles navigation, data acquisition, and communication with Earth — it’s the brains of the spacecraft.”  
      Pandora, a small satellite, will provide in-depth study of at least 20 known planets orbiting distant stars in order to determine the composition of their atmospheres — especially the presence of hazes, clouds, and water. This data will establish a firm foundation for interpreting measurements by NASA’s James Webb Space Telescope and future missions that will search for habitable worlds.
      Pandora’s spacecraft bus was photographed Jan. 10 within a thermal-vacuum testing chamber at Blue Canyon Technologies in Lafayette, Colorado. The bus provides the structure, power, and other systems that will enable the mission to help astronomers better separate stellar features from the spectra of transiting planets. NASA/Weston Maughan, BCT “We see the presence of water as a critical aspect of habitability because water is essential to life as we know it,” said Goddard’s Ben Hord, a NASA Postdoctoral Program Fellow who discussed the mission at the 245th meeting of the American Astronomical Society in National Harbor, Maryland. “The problem with confirming its presence in exoplanet atmospheres is that variations in light from the host star can mask or mimic the signal of water. Separating these sources is where Pandora will shine.”
      Funded by NASA’s Astrophysics Pioneers program for small, ambitious missions, Pandora is a joint effort between Lawrence Livermore National Laboratory in California and NASA Goddard.
      “Pandora’s near-infrared detector is actually a spare developed for the Webb telescope, which right now is the observatory most sensitive to exoplanet atmospheres,” Hord added. “In turn, our observations will improve Webb’s ability to separate the star’s signals from those of the planet’s atmosphere, enabling Webb to make more precise atmospheric measurements.”
      Astronomers can sample an exoplanet’s atmosphere when it passes in front of its star as seen from our perspective, an event called a transit. Part of the star’s light skims the atmosphere before making its way to us. This interaction allows the light to interact with atmospheric substances, and their chemical fingerprints — dips in brightness at characteristic wavelengths — become imprinted in the light.
      But our telescopes see light from the entire star as well, not just what’s grazing the planet. Stellar surfaces aren’t uniform. They sport hotter, unusually bright regions called faculae and cooler, darker regions similar to sunspots, both of which grow, shrink, and change position as the star rotates.
      An artist’s concept of the Pandora mission, seen here without the thermal blanketing that will protect the spacecraft, observing a star and its transiting exoplanet. NASA’s Goddard Space Flight Center/Conceptual Image Lab Using a novel all-aluminum, 45-centimeter-wide (17 inches) telescope, jointly developed by Livermore and Corning Specialty Materials in Keene, New Hampshire, Pandora’s detectors will capture each star’s visible brightness and near-infrared spectrum at the same time, while also obtaining the transiting planet’s near-infrared spectrum. This combined data will enable the science team to determine the properties of stellar surfaces and cleanly separate star and planetary signals.
      The observing strategy takes advantage of the mission’s ability to continuously observe its targets for extended periods, something flagship missions like Webb, which are in high demand, cannot regularly do.
      Over the course of its year-long prime mission, Pandora will observe at least 20 exoplanets 10 times, with each stare lasting a total of 24 hours. Each observation will include a transit, which is when the mission will capture the planet’s spectrum. 
      Pandora is led by NASA’s Goddard Space Flight Center. Lawrence Livermore National Laboratory provides the mission’s project management and engineering. Pandora’s telescope was manufactured by Corning and developed collaboratively with Livermore, which also developed the imaging detector assemblies, the mission’s control electronics, and all supporting thermal and mechanical subsystems. The infrared sensor was provided by NASA Goddard. Blue Canyon Technologies provided the bus and is performing spacecraft assembly, integration, and environmental testing. NASA’s Ames Research Center in California’s Silicon Valley will perform the mission’s data processing. Pandora’s mission operations center is located at the University of Arizona, and a host of additional universities support the science team.

      Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Firefly Aerospace’s Blue Ghost Mission One lander soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Wednesday, Jan. 15, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. The Blue Ghost lander will carry 10 NASA science and technology instruments to the lunar surface to further understand the Moon and help prepare for future human missions.Credit: NASA/Frank Michaux A suite of NASA scientific investigations and technology demonstrations is on its way to our nearest celestial neighbor aboard a commercial spacecraft, where they will provide insights into the Moon’s environment and test technologies to support future astronauts landing safely on the lunar surface under the agency’s Artemis campaign.
      Carrying science and tech on Firefly Aerospace’s first CLPS or Commercial Lunar Payload Services flight for NASA, Blue Ghost Mission 1 launched at 1:11 a.m. EST aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The company is targeting a lunar landing on Sunday, March 2.
      “This mission embodies the bold spirit of NASA’s Artemis campaign – a campaign driven by scientific exploration and discovery,” said NASA Deputy Administrator Pam Melroy. “Each flight we’re part of is vital step in the larger blueprint to establish a responsible, sustained human presence at the Moon, Mars, and beyond. Each scientific instrument and technology demonstration brings us closer to realizing our vision. Congratulations to the NASA, Firefly, and SpaceX teams on this successful launch.” 
      Once on the Moon, NASA will test and demonstrate lunar drilling technology, regolith (lunar rocks and soil) sample collection capabilities, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation methods. The data captured could also benefit humans on Earth by providing insights into how space weather and other cosmic forces impact our home planet.  
      “NASA leads the world in space exploration, and American companies are a critical part of bringing humanity back to the Moon,” said Nicola Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “We learned many lessons during the Apollo Era which informed the technological and science demonstrations aboard Firefly’s Blue Ghost Mission 1 – ensuring the safety and health of our future science instruments, spacecraft, and, most importantly, our astronauts on the lunar surface. I am excited to see the incredible science and technological data Firefly’s Blue Ghost Mission 1 will deliver in the days to come.”
      As part of NASA’s modern lunar exploration activities, CLPS deliveries to the Moon will help humanity better understand planetary processes and evolution, search for water and other resources, and support long-term, sustainable human exploration of the Moon in preparation for the first human mission to Mars. 
      There are 10 NASA payloads flying on this flight:
      Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will characterize heat flow from the interior of the Moon by measuring the thermal gradient and conductivity of the lunar subsurface. It will take several measurements to about a 10-foot final depth using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Lead organization: Texas Tech University  Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. Lead organization: Honeybee Robotics   Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon. The retroreflector that will fly on this mission could also collect data to understand various aspects of the lunar interior and address fundamental physics questions. Lead organization: University of Maryland Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. The RAC instrument will measure accumulation rates of lunar regolith on the surfaces of several materials including solar cells, optical systems, coatings, and sensors through imaging to determine their ability to repel or shed lunar dust. The data captured will allow the industry to test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace  Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but now will demonstrate the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University  Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. The EDS technology is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon. In the event the surfaces do not receive dust during landing, EDS has the capability to re-dust itself using the same technology. Lead organization: NASA’s Kennedy Space Center  Lunar Environment heliospheric X-ray Imager (LEXI) will capture a series of X-ray images to study the interaction of solar wind and the Earth’s magnetic field that drives geomagnetic disturbances and storms. Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact it. Lead organizations: NASA’s Goddard Space Flight Center, Boston University, and Johns Hopkins University  Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute Lunar GNSS Receiver Experiment (LuGRE) will demonstrate the possibility of acquiring and tracking signals from Global Navigation Satellite System constellations, specifically GPS and Galileo, during transit to the Moon, during lunar orbit, and on the lunar surface. If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of rocket plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier payloads are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machine’s first CLPS delivery. Lead organization: NASA’s Langley Research Center  “With 10 NASA science and technology instruments launching to the Moon, this is the largest CLPS delivery to date, and we are proud of the teams that have gotten us to this point,” said Chris Culbert, program manager for the Commercial Lunar Payload Services initiative at NASA’s Johnson Space Center in Houston. “We will follow this latest CLPS delivery with more in 2025 and later years. American innovation and interest to the Moon continues to grow, and NASA has already awarded 11 CLPS deliveries and plans to continue to select two more flights per year.”
      Firefly’s Blue Ghost lander is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side. The NASA science on this flight will gather valuable scientific data studying Earth’s nearest neighbor and helping pave the way for the first Artemis astronauts to explore the lunar surface later this decade.

      Firefly Aerospace’s Blue Ghost lander getting encapsulated in SpaceX’s rocket fairing ahead of the planned liftoff for 1:11 a.m. EST Jan. 15 from Launch Complex 39A at NASA’s Kennedy Space Center in FloridaSpaceX As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the agency is preparing to fly ten instruments aboard Firefly Aerospace’s first delivery to the Moon. These science payloads and technology demonstrations will help advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions on the Moon and beyond, for the benefit of all.
      Firefly’s lunar lander, named Blue Ghost, is scheduled to launch on a SpaceX Falcon 9 rocket Wednesday, Jan.15, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. After a 45-day cruise phase, Blue Ghost is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a basin approximately 340 miles wide (550 kilometers) located in the northeast quadrant of the Moon’s near side.
      How can we enable more precise navigation on the Moon? How do spacecraft interact with the lunar surface? How does Earth’s magnetic field influence the effects of space weather on our home planet? NASA’s instruments on this flight will conduct first-of-their-kind demonstrations to help answer these questions and more, including testing regolith sampling technologies, lunar subsurface drilling capabilities, increasing precision of positioning and navigation abilities, testing radiation tolerant computing, and learning how to mitigate lunar dust during lunar landings.

      The ten NASA payloads aboard Firefly’s Blue Ghost lander include:

      Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will measure heat flow from the Moon’s interior by measuring the thermal gradient, or changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it. LISTER will take several measurements up to 10 feet deep using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Data from LISTER will help scientists retrace the Moon’s thermal history and understand how it formed and cooled. Lead organization: Texas Tech University
      Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber (sieving) for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. The LPV payload is designed to help increase the science return from planetary missions by testing low-cost technologies for collecting regolith samples in-situ. Lead organization: Honeybee Robotics
      Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon by reflecting very short laser pulses from Earth-based Lunar Laser Ranging Observatories. The laser pulse transit time to the Moon and back is used to determine the distance. Data from NGLR could improve the accuracy of our lunar coordinate system and contribute to our understanding of the inner structure of the Moon and fundamental physics questions. Lead organization: University of Maryland
      Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. RAC will measure accumulation rates of lunar regolith on surfaces (for example, solar cells, optical systems, coatings, and sensors) through imaging to determine their ability to repel or shed lunar dust. The data captured will help test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace
      Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but this flight will provide the biggest trial yet by demonstrating the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University
      Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. EDS is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon. In the event the surfaces do not receive dust during landing, EDS has the capability to re-dust itself using the same technology. Lead organization: NASA’s Kennedy Space Center
      Lunar Environment heliospheric X-ray Imager (LEXI) will capture a series of X-ray images to study the interaction of solar wind and Earth’s magnetic field that drives geomagnetic disturbances and storms. Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact Earth. Lead organizations: Boston University, NASA’s Goddard Space Flight Center, and Johns Hopkins University
      Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute
      Lunar GNSS Receiver Experiment (LuGRE) will demonstrate the possibility of acquiring and tracking signals from GNSS (Global Navigation Satellite System) constellations, specifically GPS and Galileo, during transit to the Moon, during lunar orbit, and on the lunar surface. If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency
      Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier spacecraft and hardware are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machines’ first CLPS delivery. Lead organization: NASA’s Langley Research Center 
      Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.
