Preparations for Next Moonwalk Simulations Underway (and Underwater)
Latha Balijepalle, a senior database administrator at NASA Ames, encourages others to take a risk and pursue challenges in their work, like trying something new that might open doors to a new opportunity.NASA/Brandon Torres Navarrete When Madhavi Latha Balijepalle noticed that her morning commute took her past NASA Ames Research Center in California’s Silicon Valley, she set a new career goal for herself: working for NASA.
“I started manifesting it, thinking about it every day as I drove by. When I started looking for a new job, I saw an opening and decided to apply,” said Balijepalle, a senior database administrator working at the Airspace Operations Laboratory (AOL) at NASA Ames.
Eight and a half years later, she supports the researchers and developers who research next-generation solutions to advance aircraft technology and air traffic management.
A journey into the unknown
Balijepalle’s journey to NASA started thousands of miles away. She grew up in a small town in southern India, studying electrical engineering in college and establishing a career in information technology, working in C++ and Python.
When her husband found a job opportunity in the United States, Balijepalle’s life took an unexpected turn.
“I never planned to move to America,” said Balijepalle. “It was not easy to come here, even though my husband had a job. I stayed in India for almost nine months, before he found a different job that would help us with my visa and documentation.”
After settling into her new country, growing her family, and developing in her new career, Balijepalle began to ponder her dream job at NASA. She and her younger daughter, a fellow space fan, enjoyed talking about the agency’s work in space, and when a Linux administrator position opened up, she jumped at the chance.
A dream job becomes reality
At the lab, Balijepalle was initially responsible for managing the lab’s Linux servers and applications. Today, she also supports researchers and developers with development, automation, and deployment of their work.
“Latha is the lifeblood of the lab,” said Jeff Homola, co-leader of the Airborne Operations Laboratory at NASA Ames. “Without her unwavering dedication to making sure our systems are safe, secure, up to date, and running smoothly, we would not be able to do what we do in the lab.”
One of Balijepalle’s proudest achievements during her NASA career is her language skills. Growing up, she spoke Telugu and Hindi, and learned English, but communication was still a challenge when she arrived at NASA.
“I spoke English when I came to America, but not as well, and not using the technical language we use at NASA,” said Balijepalle. “I’m proud that I’ve improved my communications skills.”
“Step outside your comfort zone”
Looking back on the commute that changed her life, Balijepalle says she owes it all to being up to the challenge.
“I wasn’t a risk taker, I didn’t think about stepping outside my comfort zone, but as I drove by NASA Ames each day, I started to think about astronauts. They step outside their comfort zone and leave the planet, so maybe I could take a risk, too.”
For those who also dream of working at NASA one day, Balijepalle has some advice: try doing it her way.
“Start thinking about it and manifesting your dream. Maybe it will come true, and maybe it won’t, but you might as well try.”

NASA’s Dawn spacecraft captured this image of Vesta as it left the giant asteroid’s orbit in 2012. The framing camera was looking down at the north pole, which is in the middle of the image.NASA/JPL-Caltech/UCLA/MPS/DLR/IDA Known as flow formations, these channels could be etched on bodies that would seem inhospitable to liquid because they are exposed to the extreme vacuum conditions of space.
Pocked with craters, the surfaces of many celestial bodies in our solar system provide clear evidence of a 4.6-billion-year battering by meteoroids and other space debris. But on some worlds, including the giant asteroid Vesta that NASA’s Dawn mission explored, the surfaces also contain deep channels, or gullies, whose origins are not fully understood.
A prime hypothesis holds that they formed from dry debris flows driven by geophysical processes, such as meteoroid impacts, and changes in temperature due to Sun exposure. A recent NASA-funded study, however, provides some evidence that impacts on Vesta may have triggered a less-obvious geologic process: sudden and brief flows of water that carved gullies and deposited fans of sediment. By using lab equipment to mimic conditions on Vesta, the study, which appeared in Planetary Science Journal, detailed for the first time what the liquid could be made of and how long it would flow before freezing.
Although the existence of frozen brine deposits on Vesta is unconfirmed, scientists have previously hypothesized that meteoroid impacts could have exposed and melted ice that lay under the surface of worlds like Vesta. In that scenario, flows resulting from this process could have etched gullies and other surface features that resemble those on Earth.
To explore potential explanations for deep channels, or gullies, seen on Vesta, scientists used JPL’s Dirty Under-vacuum Simulation Testbed for Icy Environments, or DUSTIE, to simulate conditions on the giant asteroid that would occur after meteoroids strike the surface.NASA/JPL-Caltech But how could airless worlds — celestial bodies without atmospheres and exposed to the intense vacuum of space — host liquids on the surface long enough for them to flow? Such a process would run contrary to the understanding that liquids quickly destabilize in a vacuum, changing to a gas when the pressure drops.
“Not only do impacts trigger a flow of liquid on the surface, the liquids are active long enough to create specific surface features,” said project leader and planetary scientist Jennifer Scully of NASA’s Jet Propulsion Laboratory in Southern California, where the experiments were conducted. “But for how long? Most liquids become unstable quickly on these airless bodies, where the vacuum of space is unyielding.”
The critical component turns out to be sodium chloride — table salt. The experiments found that in conditions like those on Vesta, pure water froze almost instantly, while briny liquids stayed fluid for at least an hour. “That’s long enough to form the flow-associated features identified on Vesta, which were estimated to require up to a half-hour,” said lead author Michael J. Poston of the Southwest Research Institute in San Antonio.
Launched in 2007, the Dawn spacecraft traveled to the main asteroid belt between Mars and Jupiter to orbit Vesta for 14 months and Ceres for almost four years. Before ending in 2018, the mission uncovered evidence that Ceres had been home to a subsurface reservoir of brine and may still be transferring brines from its interior to the surface. The recent research offers insights into processes on Ceres but focuses on Vesta, where ice and salts may produce briny liquid when heated by an impact, scientists said.
Re-creating Vesta
To re-create Vesta-like conditions that would occur after a meteoroid impact, the scientists relied on a test chamber at JPL called the Dirty Under-vacuum Simulation Testbed for Icy Environments, or DUSTIE. By rapidly reducing the air pressure surrounding samples of liquid, they mimicked the environment around fluid that comes to the surface. Exposed to vacuum conditions, pure water froze instantly. But salty fluids hung around longer, continuing to flow before freezing.
The brines they experimented with were a little over an inch (a few centimeters) deep; scientists concluded the flows on Vesta that are yards to tens of yards deep would take even longer to refreeze.
The researchers were also able to re-create the “lids” of frozen material thought to form on brines. Essentially a frozen top layer, the lids stabilize the liquid beneath them, protecting it from being exposed to the vacuum of space — or, in this case the vacuum of the DUSTIE chamber — and helping the liquid flow longer before freezing again.
This phenomenon is similar to how on Earth lava flows farther in lava tubes than when exposed to cool surface temperatures. It also matches up with modeling research conducted around potential mud volcanoes on Mars and volcanoes that may have spewed icy material from volcanoes on Jupiter’s moon Europa.
“Our results contribute to a growing body of work that uses lab experiments to understand how long liquids last on a variety of worlds,” Scully said.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
With a shared commitment to fostering U.S. economic growth that benefits the American public, NASA’s Space Technology Mission Directorate and the Department of Commerce’s U.S. Patent and Trademark Office (USPTO) have signed a memorandum of understanding to strengthen collaboration in transferring federally-developed technology into the private sector, known as tech transfer.
“NASA has to invent new technology every day to carry out audacious missions like building an outpost on the Moon or looking for signs of life on the frozen moons of distant planets,” said Clayton Turner, associate administrator of the agency’s Space Technology Mission Directorate. “That is one of our greatest strengths. And with the help of the U.S. Patent and Trademark Office, we’re streamlining the process of getting those inventions into the hands of the public, boosting the economy, and benefiting everyone on Earth along the way.”
The agency’s Space Technology Mission Directorate and USPTO have been working together to share information and cooperate in mutual areas of interest, find ways to advance both agencies’ technology transfer missions, identify barriers to technology transfer, and coordinate initiatives to overcome those barriers. By combining expertise, both agencies are driving inclusive innovation and adoption of best practices, which will advance commercialization of the space agency’s most cutting-edge technology.
As part of the new agreement, NASA and USPTO are conducting an extensive study of technology transfer best practices across university and federal labs. The effort will increase opportunities for learning and growth in the technology transfer community.
“NASA’s Technology Transfer program and the U.S. Patent and Trademark Office had candid conversations with dozens of tech transfer experts about what we could do better,” said Dan Lockney, executive for NASA’s Technology Transfer program. “I can’t wait to share what we’ve learned with the entire tech transfer community nationwide. We look forward to addressing common challenges, and this paper will offer some assurance that we are on a solid, strong path to transferring technologies effectively.”
The two agencies will publish a detailed study of their findings, which will be shared at the Federal Laboratory Consortium for Technology Transfer’s national meeting in the spring. The effort will increase opportunities for learning and growth in the technology transfer community.
“We are excited to join NASA’s Space Technology Mission Directorate in publishing and sharing this insight with the larger tech transfer community, so that everyone can benefit from the successes and lessons learned from our study participants,” said Parikha Solanki, senior advisor at the U.S. Patent and Trademark Office. “We hope that the impact of this study will extend well beyond the paper, such that it might be a springboard for ongoing dialogue and knowledge sharing between tech transfer practitioners across institutions, ultimately for the benefit of the public at large.”

A rendering of Firefly’s Blue Ghost lunar lander and a rover developed for the company’s third mission to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative.Credit: Firefly Aerospace NASA continues to advance its campaign to explore more of the Moon than ever before, awarding Firefly Aerospace $179 million to deliver six experiments to the lunar surface. This fourth task order for Firefly will target landing in the Gruithuisen Domes on the near side of the Moon in 2028.
As part of the agency’s broader Artemis campaign, Firefly will deliver a group of science experiments and technology demonstrations under NASA’s CLPS initiative, or Commercial Lunar Payload Services, to these lunar domes, an area of ancient lava flows, to better understand planetary processes and evolution. Through CLPS, NASA is furthering our understanding of the Moon’s environment and helping prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach.
“The CLPS initiative carries out U.S. scientific and technical studies on the surface of the Moon by robot explorers. As NASA prepares for future human exploration of the Moon, the CLPS initiative continues to support a growing lunar economy with American companies,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “Understanding the formation of the Gruithuisen Domes, as well as the ancient lava flows surrounding the landing site, will help the U.S. answer important questions about the lunar surface.”
Firefly’s first lunar delivery is scheduled to launch no earlier than mid-January 2025 and will land near a volcanic feature called Mons Latreille within Mare Crisium, on the northeast quadrant of the Moon’s near side. Firefly’s second lunar mission includes two task orders: a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side and a delivery of a lunar orbital calibration source, scheduled in 2026.
This new delivery in 2028 will send payloads to the Gruithuisen Domes and the nearby Sinus Viscositatus. The Gruithuisen Domes have long been suspected to be formed by a magma rich in silica, similar in composition to granite. Granitic rocks form easily on Earth due to plate tectonics and oceans of water. The Moon lacks these key ingredients, so lunar scientists have been left to wonder how these domes formed and evolved over time. For the first time, as part of this task order, NASA also has contracted to provide “mobility,” or roving, for some of the scientific instruments on the lunar surface after landing. This will enable new types of U.S. scientific investigations from CLPS.
“Firefly will deliver six instruments to understand the landing site and surrounding vicinity,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “These instruments will study geologic processes and lunar regolith, test solar cells, and characterize the neutron radiation environment, supplying invaluable information as NASA works to establish a long-term presence on the Moon.”
The instruments, collectively expected to be about 215 pounds (97 kilograms) in mass, include:
Lunar Vulkan Imaging and Spectroscopy Explorer, which consists of two stationary and three mobile instruments, will study rocks and regoliths on the summit of one of the domes to determine their origin and better understand geologic processes of early planetary bodies. The principal investigator is Dr. Kerri Donaldson Hanna of the University of Central Florida, Orlando. Heimdall is a flexible camera system that will be used to take pictures of the landing site from above the horizon to the ground directly below the lander. The principal investigator is Dr. R. Aileen Yingst of the Planetary Science Institute, Tucson, Arizona. Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith is a robotic arm that will collect samples of lunar regolith and use a robotic scoop to filter and isolate particles of different sizes. The sampling technology will use a flight spare from the Mars Exploration Rover project. The principal investigator is Sean Dougherty of Maxar Technologies, Westminster, Colorado. Low-frequency Radio Observations from the Near Side Lunar Surface is designed to observe the Moon’s surface environment in radio frequencies, to determine whether natural and human-generated activity near the surface interferes with science. The project is headed up by Natchimuthuk Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Photovoltaic Investigation on the Lunar Surface will carry a set of the latest solar cells for a technology demonstration of light-to-electricity power conversion for future missions. The experiment will also collect data on the electrical charging environment of the lunar surface using a small array of solar cells. The principal investigator is Jeremiah McNatt from NASA’s Glenn Research Center in Cleveland. Neutron Measurements at the Lunar Surface is a neutron spectrometer that will characterize the surface neutron radiation environment, monitor hydrogen, and provide constraints on elemental composition. The principal investigator is Dr. Heidi Haviland of NASA’s Marshall Spaceflight Center in Huntsville, Alabama. 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. Two upcoming CLPS flights scheduled to launch in early 2025 will deliver NASA payloads to the Moon’s near side and south polar region, respectively.
