4 Min Read Eclipses Create Atmospheric Gravity Waves, NASA Student Teams Confirm
In this photo taken from the International Space Station, the Moon passes in front of the Sun casting its shadow, or umbra, and darkening a portion of the Earth's surface above Texas during the annular solar eclipse Oct. 14, 2023. Credits: NASA Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth’s atmosphere called atmospheric gravity waves. The waves’ telltale signature emerged in data captured during the North American annular solar eclipse on Oct. 14, 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP) sponsored by NASA.
Through NEBP, high school and university student teams were stationed along the eclipse path through multiple U.S. states, where they released weather balloons carrying instrument packages designed to conduct engineering studies or atmospheric science. A cluster of science teams located in New Mexico collected the data definitively linking the eclipse to the formation of atmospheric gravity waves, a finding that could lead to improved weather forecasting.
“Climate models are complicated, and they make some assumptions about what atmospheric factors to take into account.”
Angela Des Jardins
Director of the Montana Space Grant Consortium, which led NEBP.
“Understanding how the atmosphere reacts in the special case of eclipses helps us better understand the atmosphere, which in turn helps us make more accurate weather predictions and, ultimately, better understand climate change.”
Catching Waves in New Mexico
Previous ballooning teams also had hunted atmospheric gravity waves during earlier eclipses, research that was supported by NASA and the National Science Foundation. In 2019, an NEBP team stationed in Chile collected promising data, but hourly balloon releases didn’t provide quite enough detail. Attempts to repeat the experiment in 2020 were foiled by COVID-19 travel restrictions in Argentina and a heavy rainstorm that impeded data collection in Chile.
Project leaders factored in these lessons learned when planning for 2023, scheduling balloon releases every 15 minutes and carefully weighing locations with the best potential for success.
“New Mexico looked especially promising,” said Jie Gong, a researcher in the NASA Climate and Radiation Lab at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, and co-investigator of the research on atmospheric gravity waves. “The majority of atmospheric gravity sources are convection, weather systems, and mountains. We wanted to eliminate all those possible sources.”
The project created a New Mexico “supersite” in the town of Moriarty where four atmospheric science teams were clustered: two from Plymouth State University in Plymouth, New Hampshire, and one each from the State University of New York (SUNY) Albany and SUNY Oswego.
Students began launching balloons at 10 a.m. the day before the eclipse.
“They worked in shifts through the day and night, and then everyone was on site for the eclipse,” said Eric Kelsey, research associate professor at Plymouth State and the NEBP northeast regional lead.
“Our hard work really paid off. The students had a real sense of accomplishment.”

Each balloon released by the science teams carried a radiosonde, an instrument package that measured temperature, location, humidity, wind direction, and wind speed during every second of its climb through the atmosphere. Radiosondes transmitted this stream of raw data to the team on the ground. Students uploaded the data to a shared server, where Gong and two graduate students spent months processing and analyzing it.
Confirmation that the eclipse had generated atmospheric gravity waves in the skies above New Mexico came in spring 2024.
“We put all the data together according to time, and when we plotted that time series, I could already see the stripes in the signal,” Gong said. “I bombarded everybody’s email. We were quite excited.”

The program offered many students their first experience in collecting data. But the benefits go beyond technical and scientific skill.
“The students learned a ton through practicing launching weather balloons,” Kelsey said. “It was a huge learning curve. They had to work together to figure out all the logistics and troubleshoot. It’s good practice of teamwork skills.”
“All of this is technically complicated,” Des Jardins said. “While the focus now is on the science result, the most important part is that it was students who made this happen.”

NASA’s Student Launch, a STEM competition, officially kicks off its 25th anniversary with the 2025 handbook. By Wayne Smith
NASA’s Student Launch competition kicks off its 25th year with the release of the 2025 handbook, detailing how teams can submit proposals by Wednesday, Sept. 11, for the event scheduled next spring near NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Student Launch is an annual competition challenging middle school, high school, and college students to design, build, test, and launch a high-powered amateur rocket with a scientific or engineering payload. After a team is selected, they must meet documentation milestones and undergo detailed reviews throughout the school year.
Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2025 season, the payload challenge will again take inspiration from the Artemis missions, which seek to land the first woman and first person of color on the Moon.
As Student Launch celebrates its 25th anniversary, the payload challenge will include “reports” from STEMnauts, non-living objects representing astronauts. The 2024 challenge tasked teams with safely deploying a lander mid-air for a group of four STEMnauts using metrics to support a survivable landing. The lander had to be deployed without a parachute and had a minimum weight limit of five pounds.
“This year, we’re shifting the focus to communications for the payload challenge,” said John Eckhart, technical coordinator for Student Launch at Marshall. “The STEMnaut ‘crew’ must relay real-time data to the student team’s mission control. This helps connect Student Launch with the Artemis missions when NASA lands astronauts on the Moon.”
Thousands of students participated in the 2024 Student Launch competition – making up 70 teams representing 24 states and Puerto Rico. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission. The University of Notre Dame was the overall winner of the 2024 event, which culminated with a launch day open to the public.
Student Launch began in 2000 when former Marshall Director Art Stephenson started a student rocket competition at the center. It started with just two universities in Huntsville competing – Alabama A&M University and the University of Alabama in Huntsville – but has continued to soar. Since its inception, thousands of students have participated in the agency’s STEM competition, with many going on to a career with NASA.
“This remarkable journey, spanning a quarter of a century, has been a testament to the dedication, ingenuity, and passion of countless students, educators, and mentors who have contributed to the program’s success,” Eckhart said. “NASA Student Launch has been at the forefront of experiential education, providing students from middle school through university with unparalleled opportunities to engage in real-world engineering and scientific research. The program’s core mission – to inspire and cultivate the next generation of aerospace professionals and space explorers – has not only been met but exceeded in ways we could have only dreamed of.”
To encourage students to pursue degrees and careers in STEM (science, technology, engineering, and math), Marshall’s Office of STEM Engagement hosts Student Launch, providing them with real-world experiences. Student Launch is one of NASA’s nine Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of Artemis.
In addition to the NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.
“These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are the Artemis Generation, the future scientists, engineers, and innovators who will lead us into the future of space exploration.”

An artist’s concept of Intuitive Machines’ Nova-C lunar lander on the Moon’s South Pole.Credit: Intuitive Machines A new set of NASA science experiments and technology demonstrations will arrive at the lunar South Pole in 2027 following the agency’s latest CLPS (Commercial Lunar Payload Services) initiative delivery award. Intuitive Machines of Houston will receive $116.9 million to deliver six NASA payloads to a part of the Moon where nighttime temperatures are frigid, the terrain is rugged, and the permanently shadowed regions could help reveal the origin of water throughout our solar system.
Part of the agency’s broader Artemis campaign, CLPS aims to conduct science on the Moon for the benefit of all, including experiments and demos that support missions with crew on the lunar surface.
“This marks the 10th CLPS delivery NASA has awarded, and the fourth planned for delivery to the South Pole of the Moon,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “By supporting a robust cadence of CLPS flights to a variety of locations on the lunar surface, including two flights currently planned by companies for later this year, NASA will explore more of the Moon than ever before.”
NASA has awarded Intuitive Machine’s four task orders. The company delivered six NASA payloads to Malapert A in the South Pole region of the Moon in early 2024. With this lunar South Pole delivery, Intuitive Machines will be responsible for payload integration, launch from Earth, safe landing on the Moon, and mission operations.
“The instruments on this newly awarded flight will help us achieve multiple scientific objectives and strengthen our understanding of the Moon’s environment,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “For example, they’ll help answer key questions about where volatiles – such as water, ice, or gas – are found on the lunar surface and measure radiation in the South Pole region, which could advance our exploration efforts on the Moon and help us with continued exploration of Mars.”
The instruments, collectively expected to be about 174 pounds (79 kilograms) in mass, include:
The Lunar Explorer Instrument for Space Biology Applications will deliver yeast to the lunar surface and study its response to radiation and lunar gravity. The payload is managed by NASA’s Ames Research Center in Silicon Valley, California. Package for Resource Observation and In-Situ Prospecting for Exploration, Characterization and Testing is a suite of instruments that will drill down to 3.3 feet (1 meter) beneath the lunar surface, extract samples, and process them in-situ in a miniaturized laboratory, to identify possible volatiles (water, ice, or gas) trapped at extremely cold temperatures under the surface. This suite is led by ESA (European Space Agency). The Laser Retroreflector Array is a collection of eight retroreflectors that will enable lasers to precisely measure the distance between a spacecraft and the reflector on the lander. The array is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. The retroflector array is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Surface Exosphere Alterations by Landers will investigate the chemical response of lunar regolith to the thermal, physical, and chemical disturbances generated during a landing, and evaluate contaminants injected into the regolith by the lander. It will give insight into how a spacecraft landing might affect the composition of samples collected nearby. This payload is managed by NASA Goddard. The Fluxgate Magnetometer will characterize certain magnetic fields to improve the understanding of energy and particle pathways at the lunar surface and is managed by NASA Goddard. The Lunar Compact Infrared Imaging System will deploy a radiometer – a device that measures infrared wavelengths of light – to explore the Moon’s surface composition, map its surface temperature distribution, and demonstrate the instrument’s feasibility for future lunar resource utilization activities. The imaging system is managed by the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder. Under CLPS, multiple commercial deliveries to different geographic regions will help NASA conduct science and continue working toward a long-term human presence on the Moon. Future deliveries will include sophisticated science experiments, and technology demonstrations as part of the agency’s Artemis campaign. Two upcoming CLPS flights slated to launch near the end of 2024 will deliver NASA payloads to the Moon’s nearside and South Pole, including the Intuitive Machines-2 delivery of NASA’s first on-site demonstration of searching for water and other chemical compounds 3.3 feet below the surface of the Moon, using a drill and mass spectrometer.

A prototype of a robot built to access underwater areas where Antarctic ice shelves meet land is lowered through the ice during a field test north of Alaska in March. JPL is developing the concept, called IceNode, to take melt-rate measurements that would improve the accuracy of sea level rise projections.U.S. Navy/Scott Barnes Conducted through the U.S. Navy Arctic Submarine Laboratory’s biennial Ice Camp, this field test marked IceNode’s first in a polar environment. The team hopes to one day deploy a fleet of the autonomous robots beneath Antarctic ice shelves.U.S. Navy/Scott Barnes Called IceNode, the project envisions a fleet of autonomous robots that would help determine the melt rate of ice shelves.
On a remote patch of the windy, frozen Beaufort Sea north of Alaska, engineers from NASA’s Jet Propulsion Laboratory in Southern California huddled together, peering down a narrow hole in a thick layer of sea ice. Below them, a cylindrical robot gathered test science data in the frigid ocean, connected by a tether to the tripod that had lowered it through the borehole.
This test gave engineers a chance to operate their prototype robot in the Arctic. It was also a step toward the ultimate vision for their project, called IceNode: a fleet of autonomous robots that would venture beneath Antarctic ice shelves to help scientists calculate how rapidly the frozen continent is losing ice — and how fast that melting could cause global sea levels to rise.
Warming Waters, Treacherous Terrain
If melted completely, Antarctica’s ice sheet would raise global sea levels by an estimated 200 feet (60 meters). Its fate represents one of the greatest uncertainties in projections of sea level rise. Just as warming air temperatures cause melting at the surface, ice also melts when in contact with warm ocean water circulating below. To improve computer models predicting sea level rise, scientists need more accurate melt rates, particularly beneath ice shelves — miles-long slabs of floating ice that extend from land. Although they don’t add to sea level rise directly, ice shelves crucially slow the flow of ice sheets toward the ocean.
A remote camera captured an IceNode prototype deployed below the frozen surface of Lake Superior, off Michigan’s Upper Peninsula, during a field test in 2022. The three thin legs of the robot’s “landing gear” affix the prototype to the icy ceiling.NASA/JPL-Caltech The challenge: The places where scientists want to measure melting are among Earth’s most inaccessible. Specifically, scientists want to target the underwater area known as the “grounding zone,” where floating ice shelves, ocean, and land meet — and to peer deep inside unmapped cavities where ice may be melting the fastest. The treacherous, ever-shifting landscape above is dangerous for humans, and satellites can’t see into these cavities, which are sometimes beneath a mile of ice. IceNode is designed to solve this problem.
“We’ve been pondering how to surmount these technological and logistical challenges for years, and we think we’ve found a way,” said Ian Fenty, a JPL climate scientist and IceNode’s science lead. “The goal is getting data directly at the ice-ocean melting interface, beneath the ice shelf.”
Floating Fleet
Harnessing their expertise in designing robots for space exploration, IceNode’s engineers are developing vehicles about 8 feet (2.4 meters) long and 10 inches (25 centimeters) in diameter, with three-legged “landing gear” that springs out from one end to attach the robot to the underside of the ice. The robots don’t feature any form of propulsion; instead, they would position themselves autonomously with the help of novel software that uses information from models of ocean currents.
JPL’s IceNode project is designed for one of Earth’s most inaccessible locations: underwater cavities deep beneath Antarctic ice shelves. The goal is getting melt-rate data directly at the ice-ocean interface in areas where ice may be melting the fastest. Credit: NASA/JPL-Caltech Released from a borehole or a vessel in the open ocean, the robots would ride those currents on a long journey beneath an ice shelf. Upon reaching their targets, the robots would each drop their ballast and rise to affix themselves to the bottom of the ice. Their sensors would measure how fast warm, salty ocean water is circulating up to melt the ice, and how quickly colder, fresher meltwater is sinking.
The IceNode fleet would operate for up to a year, continuously capturing data, including seasonal fluctuations. Then the robots would detach themselves from the ice, drift back to the open ocean, and transmit their data via satellite.
“These robots are a platform to bring science instruments to the hardest-to-reach locations on Earth,” said Paul Glick, a JPL robotics engineer and IceNode’s principal investigator. “It’s meant to be a safe, comparatively low-cost solution to a difficult problem.”
Arctic Field Test
While there is additional development and testing ahead for IceNode, the work so far has been promising. After previous deployments in California’s Monterey Bay and below the frozen winter surface of Lake Superior, the Beaufort Sea trip in March 2024 offered the first polar test. Air temperatures of minus 50 degrees Fahrenheit (minus 45 Celsius) challenged humans and robotic hardware alike.
The test was conducted through the U.S. Navy Arctic Submarine Laboratory’s biennial Ice Camp, a three-week operation that provides researchers a temporary base camp from which to conduct field work in the Arctic environment.
As the prototype descended about 330 feet (100 meters) into the ocean, its instruments gathered salinity, temperature, and flow data. The team also conducted tests to determine adjustments needed to take the robot off-tether in future.
“We’re happy with the progress. The hope is to continue developing prototypes, get them back up to the Arctic for future tests below the sea ice, and eventually see the full fleet deployed underneath Antarctic ice shelves,” Glick said. “This is valuable data that scientists need. Anything that gets us closer to accomplishing that goal is exciting.”
IceNode has been funded through JPL’s internal research and technology development program and its Earth Science and Technology Directorate. JPL is managed for NASA by Caltech in Pasadena, California.
