Preparations for Next Moonwalk Simulations Underway (and Underwater)
Piloted by NASA’s Tim Williams, the ER-2 science aircraft ascends for one of the final science flights for the GSFC Lidar Observation and Validation Experiment (GLOVE) on Feb. 1, 2025. As a collaboration between engineers, scientists, and aircraft professionals, GLOVE aims to improve satellite data products for Earth Science applications. NASA/Steve Freeman In February, NASA’s ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is exploring how instruments analyzing clouds can improve data measurement methods.
Researchers participating in the Goddard Space Flight Center Lidar Observation and Validation Experiment (GLOVE) used the ER-2 – based at NASA’s Armstrong Flight Research Center in Edwards, California – to validate satellite data about cloud and airborne particles in the Earth’s atmosphere. Scientists are using GLOVE instruments installed onboard the aircraft to measure and validate data about clouds generated by satellite sensors already orbiting in space around Earth.
“The GLOVE data will allow us to test new artificial intelligence algorithms in data processing,” said John Yorks, principal investigator for GLOVE and research physical scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “These algorithms aim to improve the cloud and aerosol detection in data produced by the satellites.”

The Roscoe instrument will be uploaded onto NASA’s ER-2 science aircraft.NASA/Steve Freeman The validation provided by GLOVE is crucial because it ensures the accuracy and reliability of satellite data. “The instruments on the plane provide a higher resolution measurement ‘truth’ to ensure the data is a true representation of the atmospheric scene being sampled,” Yorks said.
The ER-2 flew over various parts of Oregon, Arizona, Utah, and Nevada, as well as over the Pacific Ocean off the coast of California. These regions reflected various types of atmospheres, including cirrus clouds, marine stratocumulus, rain and snow, and areas with multiple types of clouds.
“The goal is to improve satellite data products for Earth science applications,” Yorks said. “These measurements allow scientists and decision-makers to confidently use this satellite information for applications like weather forecasting and hazard monitoring.”
Researcher Jackson Begolka from the University of Iowa examines instrument connectors onboard the ER-2 aircraft at NASA’s Armstrong Flight Research Center in Edwards, California, on Feb. 1, 2025. The GLOVE instrument will validate data from satellites orbiting the Earth.NASA/Steve Freeman The four instruments installed on the ER-2 were the Cloud Physics Lidar, the Roscoe Lidar, the enhanced Moderate Resolution Imaging Spectroradiometer Airborne Simulator, and the Cloud Radar System. These instruments validate data produced by sensors on NASA’s Ice, Cloud, and Land Elevation Satellite 2 (ICESat-2) and the Earth Cloud, Aerosol and Radiation Explorer (EarthCARE), a joint venture between the ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency).
“Additionally, the EarthCARE satellite is flying the first ever Doppler radar for measurements of air motions within clouds,” Yorks said. While the ER-2 is operated by pilots and aircrew from NASA Armstrong, these instruments are supported by scientists from NASA Goddard, NASA’s Ames Research Center in California’s Silicon Valley, and the Naval Research Laboratory office in Monterey, California, as well as by students from the University of Iowa in Iowa City and the University of Maryland College Park.

How NASA Science Data Defends Earth from Asteroids
Artist’s impression of NASA’s DART mission, which collided with the asteroid Dimorphos in 2022 to test planetary defense techniques. Open science data practices help researchers identify asteroids that pose a hazard to Earth, opening the possibility for deflection should an impact threat be identified. NASA/Johns Hopkins APL/Steve Gribben The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA’s Center for Near Earth Object Studies (CNEOS) at the agency’s Jet Propulsion Laboratory in Southern California. The probability of collision peaked at over 3% on Feb. 18 — the highest ever recorded for an object of its size. This sparked concerns about the damage the asteroid might do should it hit Earth.
New data collected in the following days lowered the probability to well under 1%, and 2024 YR4 is no longer considered a potential Earth impactor. However, the event underscored the importance of surveying asteroid populations to reveal possible threats to Earth. Sharing scientific data widely allows scientists to determine the risk posed by the near-Earth asteroid population and increases the chances of identifying future asteroid impact hazards in NASA science data.
“The planetary defense community realizes the value of making data products available to everyone,” said James “Gerbs” Bauer, the principal investigator for NASA’s Planetary Data System Small Bodies Node at the University of Maryland in College Park, Maryland.
How Scientists Spot Asteroids That Could Hit Earth
Professional scientists and citizen scientists worldwide play a role in tracking asteroids. The Minor Planet Center, which is housed at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, collects and verifies vast numbers of asteroid and comet position observations submitted from around the globe. NASA’s Small Bodies Node distributes the data from the Minor Planet Center for anyone who wants to access and use it.
A near-Earth object (NEO) is an asteroid or comet whose orbit brings it within 120 million miles of the Sun, which means it can circulate through Earth’s orbital neighborhood. If a newly discovered object looks like it might be an NEO, information about the object appears on the Minor Planet Center’s NEO Confirmation Page. Members of the planetary science community, whether or not they are professional scientists, are encouraged to follow up on these objects to discover where they’re heading.
The asteroid 2024 YR4 as viewed on January 27, 2025. The image was taken by the Magdalena Ridge 2.4m telescope, one of the largest telescopes in NASA’s Planetary Defense network. Asteroid position information from observations such as this one are shared through the Minor Planet Center and NASA’s Small Bodies Node to help scientists pinpoint the chances of asteroids colliding with Earth. NASA/Magdalena Ridge 2.4m telescope/New Mexico Institute of Technology/Ryan When an asteroid’s trajectory looks concerning, CNEOS alerts NASA’s Planetary Defense Coordination Office at NASA Headquarters in Washington, which manages NASA’s ongoing effort to protect Earth from dangerous asteroids. NASA’s Planetary Defense Coordination Office also coordinates the International Asteroid Warning Network (IAWN), which is the worldwide collaboration of asteroid observers and modelers.
Orbit analysis centers such as CNEOS perform finer calculations to nail down the probability of an asteroid colliding with Earth. The open nature of the data allows the community to collaborate and compare, ensuring the most accurate determinations possible.
How NASA Discovered Risks of Asteroid 2024 YR4
The asteroid 2024 YR4 was initially discovered by the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) survey, which aims to discover potentially hazardous asteroids. Scientists studied additional data about the asteroid from different observatories funded by NASA and from other telescopes across the IAWN.
At first, 2024 YR4 had a broad uncertainty in its future trajectory that passed over Earth. As the planetary defense community collected more observations, the range of possibilities for the asteroid’s future position on Dec. 22, 2032 clustered over Earth, raising the apparent chances of collision. However, with the addition of even more data points, the cluster of possibilities eventually moved off Earth.
This visualization from NASA’s Center for Near Earth Object Studies shows the evolution of the risk corridor for asteroid 2024 YR4, using data from observations made up to Feb. 23, 2025. Each yellow dot represents the asteroid’s possible location on Dec. 22, 2032. As the range of possible locations narrowed, the dots at first converged on Earth, before skewing away harmlessly. NASA/JPL/CNEOS Having multiple streams of data available for analysis helps scientists quickly learn more about NEOs. This sometimes involves using data from observatories that are mainly used for astrophysics or heliophysics surveys, rather than for tracking asteroids.
“The planetary defense community both benefits from and is beneficial to the larger planetary and astronomy related ecosystem,” said Bauer, who is also a research professor in the Department of Astronomy at the University of Maryland. “Much of the NEO survey data can also be used for searching astrophysical transients like supernova events. Likewise, astrophysical sky surveys produce data of interest to the planetary defense community.”
How Does NASA Stop Asteroids From Hitting Earth?
In 2022, NASA’s DART (Double Asteroid Redirection Test) mission successfully impacted with the asteroid Dimorphos, shortening the time it takes to orbit around its companion asteroid Didymos by 33 minutes. Didymos had no chance of hitting Earth, but the DART mission’s success means that NASA has a tested technique to consider when addressing a future asteroid potential impact threat.
Artist’s impression of NASA’s upcoming NEO Surveyor mission, which will search for potentially hazardous near-Earth objects. The mission will follow open data practices to improve the chances of identifying dangerous asteroids. NASA/JPL-Caltech To increase the chances of discovering asteroid threats to Earth well in advance, NASA is working on a new space-based observatory, NEO Surveyor, which will be the first spacecraft specifically designed to look for asteroids and comets that pose a hazard to Earth. The mission is expected to launch in the fall of 2027, and the data it collects will be available to everyone through NASA archives.
“Many of the NEOs that pose a risk to Earth remain to be found,” Bauer said. “An asteroid impact has a very low likelihood at any given time, but consequences could be high, and open science is an important component to being vigilant.”

NASA Science Supports Data Literacy for K-12 Students
Data – and our ability to understand and use it – shapes nearly every aspect of our world, from decisions in our lives to the skills we need in the workplace and more. All of us, as either producers or consumers of data, will experience how it can be used to problem-solve and think critically as we navigate the world around us. For that reason, Data Science has become an increasingly essential and growing field that combines the collection, organization, analysis, interpretation, and sharing of data in virtually every area of life. As more data become more openly available, our Data Science skills will be of increasing importance. And yet, there is a widening gap between what students learn in school and the skills they will need to succeed in a data-driven world. The integration of Data Science into K-12 education opens doors to higher education, high-paying careers, and empowering learners to eventually participate in the creation of new knowledge and understanding of our world, and at least 29 states have reported some level of data science implementation at the K-12 level, including standard or framework adoption, course piloting, and educator professional learning.
In February 2025, the first-ever Data Science Education K-12: Research to Practice Conference (DS4E) took place in San Antonio, TX. A number of representatives from NASA’s Science Activation program and other NASA partners attended and presented along with over 250 educators, researchers, and school leaders from across the nation. Science Activation projects share a passion for helping people of all ages and backgrounds connect with NASA science experts, content, experiences, and learning resources, and the AEROKATS & ROVER Education Network (AREN); Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES); Global Learning and Observations to Benefit the Environment (GLOBE) Mission Earth; and My NASA Data teams did just that. Their presentations at the conference included:
“BYOD – Build or Bring Your Own Data: Developing K-12 Datasets” (PLACES) “Using NASA Data Resources as a Tool to Support Storytelling with Data in K-12 Education” (My NASA Data) “Place-Based Data Literacy: Real People, Real Places, Real Data” (AREN) Conference participants expressed interest in learning more about NASA assets, including data and subject matter experts. Stemming from their participation in this first DS4E, several Science Activation teams are collaborating to potentially host regional events next year under the umbrella of this effort (PLACES in particular), a wonderful example of how Science Activation project teams help lead the charge in the advancement of key Science, Technology, Education, and Mathematics (STEM) fields, such as Data Science, to activate minds and promote a deeper understanding of our world and beyond.

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.
