NASA has selected 12 student teams to develop solutions for storing and transferring the super-cold liquid propellants needed for future long-term exploration beyond Earth orbit.
The agency’s 2025 Human Lander Challenge is designed to inspire and engage the next generation of engineers and scientists as NASA and its partners prepare to send astronauts to the Moon through the Artemis campaign in preparation for future missions to Mars. The commercial human landing systems will serve as the primary mode of transportation that will safely take astronauts and, later, large cargo from lunar orbit to the surface of the Moon and back.
For its second year, the competition invites university students and their faculty advisors to develop innovative, “cooler” solutions for in-space cryogenic, or super cold, liquid propellant storage and transfer systems. These cryogenic fluids, like liquid hydrogen or liquid oxygen, must stay extremely cold to remain in a liquid state, and the ability to effectively store and transfer them in space will be increasingly vital for future long-duration missions. Current technology allows cryogenic liquids to be stored for a relatively short amount of time, but future missions will require these systems to function effectively over several hours, weeks, and even months.
The 12 selected finalists have been awarded a $9,250 development stipend to further develop their concepts in preparation for the next stage of the competition.
The 2025 Human Lander Challenge finalist teams are:
California State Polytechnic University, Pomona, “THERMOSPRING: Thermal Exchange Reduction Mechanism using Optimized SPRING” Colorado School of Mines, “MAST: Modular Adaptive Support Technology” Embry-Riddle Aeronautical University, “Electrical Capacitance to High-resolution Observation (ECHO)” Jacksonville University, “Cryogenic Complex: Cryogenic Tanks and Storage Systems – on the Moon and Cislunar Orbit” Jacksonville University, “Cryogenic Fuel Storage and Transfer: The Human Interface – Monitoring and Mitigating Risks” Massachusetts Institute of Technology, “THERMOS: Translunar Heat Rejection and Mixing for Orbital Sustainability” Old Dominion University, “Structural Tensegrity for Optimized Retention in Microgravity (STORM)” Texas A&M University, “Next-generation Cryogenic Transfer and Autonomous Refueling (NeCTAR)” The College of New Jersey, “Cryogenic Orbital Siphoning System (CROSS)” The Ohio State University, “Autonomous Magnetized Cryo-Couplers with Active Alignment Control for Propellant Transfer (AMCC-AAC) University of Illinois, Urbana-Champaign, “Efficient Cryogenic Low Invasive Propellant Supply Exchange (ECLIPSE)” Washington State University, “CRYPRESS Coupler for Liquid Hydrogen Transfer” Finalist teams will now work to submit a technical paper further detailing their concepts. They will present their work to a panel of NASA and industry judges at the 2025 Human Lander Competition Forum in Huntsville, Alabama, near NASA’s Marshall Space Flight Center, in June 2025. The top three placing teams will share a total prize purse of $18,000.
“By engaging college students in solving critical challenges in cryogenic fluid technologies and systems-level solutions, NASA fosters a collaborative environment where academic research meets practical application,” said Tiffany Russell Lockett, office manager for the Human Landing System Mission Systems Management Office at NASA Marshall. “This partnership not only accelerates cryogenics technology development but also prepares the Artemis Generation – the next generation of engineers and scientists – to drive future breakthroughs in spaceflight.”
NASA’s Human Lander Challenge is sponsored by the agency’s Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace.

5 Min Read NASA Langley’s Legacy of Landing
The first image of the Moon taken by the cameras on the Lunar Orbiter in 1966. Credits: NASA Landing safely on the surface of another planetary body, like the Moon or Mars, is one of the most important milestones of any given space mission. From the very beginning, NASA’s Langley Research Center has been at the heart of the entry, descent and landing (EDL) research that enables our exploration. Today, NASA Langley’s legacy of landing continues at the forefront of present day lunar missions and as NASA prepares for future travel to more distant worlds.
Project Mercury: 1958
Project Mercury was the United States’ first human-in-space program, led by NASA’s Space Task Group located at NASA Langley. There were five major programs of study and experimentation.
An airdrop study that helped us understand the characteristics of the Mercury capsule as it returned to Earth. A group of study focused on the escape systems, ultimately becoming known as the launch abort system. Exhaustive wind-tunnel studies of the blunt-nosed capsule design and its aerodynamic stability at various altitudes and speeds and angles of reentry, all with a focus on making the capsule safe and stable. A study on the problem of landing impact, resulting in the development of absorption systems that minimized the shock of impact to the capsule’s pilot. Studies into the use of drogue parachutes and their characteristics at high altitudes and speeds, ensuring that they would be able to stabilize and slow the capsule’s descent for a safe landing. All of this research went on to inform the subsequent Gemini and Apollo programs. All of this research went on to inform the subsequent Gemini and Apollo programs.
Apollo Program: 1962
In 1961, President John F. Kennedy committed to putting Americans on the surface of the Moon and shortly after that historic declaration, NASA’s Apollo program was born. In the years that followed, the original team of NASA astronauts completed their basic training at NASA Langley’s Lunar Landing Research Facility (LLRF). When Apollo 11 successfully landed the first humans on the Moon in 1969, NASA Langley had played a pivotal role in the monumental success.
Lunar Orbiter: 1966
The Lunar Orbiter missions launched with the purpose of mapping the lunar surface and identifying potential landing sites ahead of the Apollo landings. From 1966 to 1967, the five successful Lunar Orbiter missions, led and managed by Langley Research Center, resulted in 99% of the moon photographed and a suitable site selected for the upcoming human landings.
Viking: 1976
After the success of Apollo, NASA set its sights further across the solar system to Mars. Two Viking missions aimed to successfully place landers on the Red Planet and capture high resolution images of the Martian surfaces, assisting in the search for life. Langley Research Center was chosen to lead this inaugural Mars mission and went on to play key roles in the missions to Mars that followed.
HIAD: 2009 – Present
Successful landings on Mars led to more ambitious dreams of landing larger payloads, including those that could support future human exploration. In order to land those payloads safely, a new style of heat shield would be needed. Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology was positioned as an answer to the payload problem, enabling missions to use inflatable heat shields to slow down and protect a payload as it enters a planet’s atmosphere at hypersonic speeds.
IRVE – 2009-2012
Two successful Inflatable Reentry Vehicle Experiments (IRVE) proved the capability of inflatable heat shield technology and opened the door for larger iterations.
LOFTID – 2022
The Low Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) followed in the footsteps of its predecessor IRVE with a larger aeroshell that could be deployed to a scale much larger than the shroud. The 2022 successful test of this technology further proved the capability of HIAD technology.
MEDLI 1 and 2: 2012 & 2020
As a part of the Mars Science Laboratory (MSL) mission, NASA Langley’s Mars Entry, Descent and Landing Instrument (MEDLI) was designed to gather data from the MSL entry vehicle’s heatshield during its entry and descent to the surface of Mars. MEDLI2 expanded on that groundbreaking data during the Mars 2020 mission which safely landed the Perseverance rover after successfully entering the planet’s arid atmosphere, and enabling improvements on the design for future entry systems.
Curiosity Rover
Curiosity was the largest and most capable rover ever sent to Mars when it launched in 2011. Leading up the mission, Langley engineers performed millions of simulations of the entry, descent and landing phase — or the so-called “Seven Minutes of Terror” — that determines success or failure. Curiosity continues to look for signs that Mars once was – or still is – a habitable place for life as we know it.
CLPS: 2023 – Present
The Commercial Lunar Payload Services initiative takes the Artemis mission further by working with commercial partners to advance the technology needed to return humans to the Moon and enable humanity to explore Mars.
NDL
Navigation Doppler Lidar (NDL) technology, developed at Langley Research Center, uses lasers to assist spacecraft in identifying safe locations to land. In 2024, NDL flew on the Intuitive Machines’ uncrewed Nova-C lander, with its laser instruments designed to measure velocity and altitude to within a few feet. While NASA planetary landers have traditionally relied on radar and used radio waves, NDL technology has proven more accurate and less heavy, both major benefits for cost and space savings as we continue to pursue planetary missions.
SCALPSS
Like Lunar Orbiter and the Viking missions before it, Stereo Cameras for Lunar Plume Surface Studies (SCALPSS) set out to better understand the surface of another celestial body. These cameras affixed to the bottom of a lunar lander focus on the interaction between the lander’s rocket plumes and the lunar surface. The SCALPSS 1.1 instrument captured first-of-its-kind imagery as the engine plumes of Firefly’s Blue Ghost lander reached the Moon’s surface. These images will serve as key pieces of data as trips to the Moon increase in the coming years.

An image of the Milky Way captured by the MeerKAT radio telescope array puts the James Webb Space Telescope’s image of the Sagittarius C region in context. Full image below. Credits:
NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Follow-up research on a 2023 image of the Sagittarius C stellar nursery in the heart of our Milky Way galaxy, captured by NASA’s James Webb Space Telescope, has revealed ejections from still-forming protostars and insights into the impact of strong magnetic fields on interstellar gas and the life cycle of stars.
“A big question in the Central Molecular Zone of our galaxy has been, if there is so much dense gas and cosmic dust here, and we know that stars form in such clouds, why are so few stars born here?” said astrophysicist John Bally of the University of Colorado Boulder, one of the principal investigators. “Now, for the first time, we are seeing directly that strong magnetic fields may play an important role in suppressing star formation, even at small scales.”
Detailed study of stars in this crowded, dusty region has been limited, but Webb’s advanced near-infrared instruments have allowed astronomers to see through the clouds to study young stars like never before.
“The extreme environment of the galactic center is a fascinating place to put star formation theories to the test, and the infrared capabilities of NASA’s James Webb Space Telescope provide the opportunity to build on past important observations from ground-based telescopes like ALMA and MeerKAT,” said Samuel Crowe, another principal investigator on the research, a senior undergraduate at the University of Virginia and a 2025 Rhodes Scholar.
Bally and Crowe each led a paper published in The Astrophysical Journal.
Image A: Milky Way Center (MeerKAT and Webb)
An image of the Milky Way captured by the MeerKAT (formerly the Karoo Array Telescope) radio telescope array puts the James Webb Space Telescope’s image of the Sagittarius C region in context. Like a super-long exposure photograph, MeerKAT shows the bubble-like remnants of supernovas that exploded over millennia, capturing the dynamic nature of the Milky Way’s chaotic core. At the center of the MeerKAT image the region surrounding the Milky Way’s supermassive black hole blazes bright. Huge vertical filamentary structures echo those captured on a smaller scale by Webb in Sagittarius C’s blue-green hydrogen cloud. NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Image B: Milky Way Center (MeerKAT and Webb), Labeled
The star-forming region Sagittarius C, captured by the James Webb Space Telescope, is about 200 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. The spectral index at the lower left shows how color was assigned to the radio data to create the image. On the negative end, there is non-thermal emission, stimulated by electrons spiraling around magnetic field lines. On the positive side, thermal emission is coming from hot, ionized plasma. For Webb, color is assigned by shifting the infrared spectrum to visible light colors. The shortest infrared wavelengths are bluer, and the longer wavelengths appear more red. NASA, ESA, CSA, STScI, SARAO, Samuel Crowe (UVA), John Bally (CU), Ruben Fedriani (IAA-CSIC), Ian Heywood (Oxford) Using Infrared to Reveal Forming Stars
In Sagittarius C’s brightest cluster, the researchers confirmed the tentative finding from the Atacama Large Millimeter Array (ALMA) that two massive stars are forming there. Along with infrared data from NASA’s retired Spitzer Space Telescope and SOFIA (Stratospheric Observatory for Infrared Astronomy) mission, as well as the Herschel Space Observatory, they used Webb to determine that each of the massive protostars is already more than 20 times the mass of the Sun. Webb also revealed the bright outflows powered by each protostar.
Even more challenging is finding low-mass protostars, still shrouded in cocoons of cosmic dust. Researchers compared Webb’s data with ALMA’s past observations to identify five likely low-mass protostar candidates.
The team also identified 88 features that appear to be shocked hydrogen gas, where material being blasted out in jets from young stars impacts the surrounding gas cloud. Analysis of these features led to the discovery of a new star-forming cloud, distinct from the main Sagittarius C cloud, hosting at least two protostars powering their own jets.
“Outflows from forming stars in Sagittarius C have been hinted at in past observations, but this is the first time we’ve been able to confirm them in infrared light. It’s very exciting to see, because there is still a lot we don’t know about star formation, especially in the Central Molecular Zone, and it’s so important to how the universe works,” said Crowe.
Magnetic Fields and Star Formation
Webb’s 2023 image of Sagittarius C showed dozens of distinctive filaments in a region of hot hydrogen plasma surrounding the main star-forming cloud. New analysis by Bally and his team has led them to hypothesize that the filaments are shaped by magnetic fields, which have also been observed in the past by the ground-based observatories ALMA and MeerKAT (formerly the Karoo Array Telescope).
“The motion of gas swirling in the extreme tidal forces of the Milky Way’s supermassive black hole, Sagittarius A*, can stretch and amplify the surrounding magnetic fields. Those fields, in turn, are shaping the plasma in Sagittarius C,” said Bally.
The researchers think that the magnetic forces in the galactic center may be strong enough to keep the plasma from spreading, instead confining it into the concentrated filaments seen in the Webb image. These strong magnetic fields may also resist the gravity that would typically cause dense clouds of gas and dust to collapse and forge stars, explaining Sagittarius C’s lower-than-expected star formation rate.
“This is an exciting area for future research, as the influence of strong magnetic fields, in the center of our galaxy or other galaxies, on stellar ecology has not been fully considered,” said Crowe.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
