Preparations for Next Moonwalk Simulations Underway (and Underwater)
NuCLEUS, developed by Interstellar Lab, is an autonomous system that grows microgreens, vegetables, and more for astronauts to eat in space.Interstellar Lab NASA invests in technologies that have the potential to revolutionize space exploration, including the way astronauts live in space. Through the Deep Space Food Challenge, NASA, in partnership with CSA (Canadian Space Agency), sought novel food production systems that could provide long-duration human space exploration missions with safe, nutritious, and tasty food. Three winners selected last summer are now taking their technology to new heights – figuratively and literally – through commercial partnerships.
Interstellar Lab of Merritt Island, Florida, won the challenge’s $750,000 grand prize for its food production system NuCLEUS (Nutritional Closed-Loop Eco-Unit System), by demonstrating an autonomous operation growing microgreens, vegetables, and mushrooms, as well as sustaining insects for use in an astronaut’s diet. To address the requirements of the NASA challenge, NuCLEUS includes an irrigation system that sustains crop growth with minimal human intervention. This end-to-end system supplies fresh ingredients to support astronauts’ health and happiness, with an eye toward what the future of dining on deep space missions to Mars and the Moon may look like.
Since the close of the challenge, Interstellar Lab has partnered with aerospace company Vast to integrate a spinoff of NuCLEUS, called Eden 1.0, on Haven-1, a planned commercial space station. Eden 1.0 is a plant growth unit designed to conduct research on plants in a microgravity environment using functions directly stemming from NuCLEUS.
“The NASA Deep Space Food Challenge was a pivotal catalyst for Interstellar Lab, driving us to refine our NuCLEUS system and directly shaping the development of Eden 1.0, setting the stage for breakthroughs in plant growth research to sustain life both in space and on Earth,” said Barbara Belvisi, founder and CEO of Interstellar Lab.
Fuanyi Fobellah, one of the “Simunauts” from The Ohio State University who tested food production technologies as part of the Deep Space Food Challenge, removes a cooked omelet from the SATED appliance.NASA/Savannah Bullard Team SATED (Safe Appliance, Tidy, Efficient & Delicious) of Boulder, Colorado, earned a $250,000 second prize for its namesake appliance, which creates an artificial gravitational force that presses food ingredients against its heated inner surface for cooking. The technology was developed by Jim Sears, who entered the contest as a one-person team and has since founded the small business SATED Space LLC.
At the challenge finale event, the technology was introduced to the team of world-renowned chef and restaurant owner, José Andrés. The SATED technology is undergoing testing with the José Andrés Group, which could add to existing space food recipes that include lemon cake, pizza, and quiche. The SATED team also is exploring partnerships to expand the list of ingredients compatible with the appliance, such as synthetic cooking oils safe for space.
Delicious food was a top priority in the Deep Space Food Challenge. Sears noted the importance of food that is more than mere sustenance. “When extremely high performance is required, and the situations are demanding, tough, and lonely, the thing that pulls it all together and makes people operate at their best is eating fresh cooked food in community.”
Team Nolux won a $250,000 second-place prize for its Nolux food system that uses artificial photosynthesis to grow ingredients that could be used by astronauts in space.OSU/CFAES/Kenneth Chamberlain Team Nolux, formed from faculty members, graduate, and undergraduate students from the University of California, Riverside, also won a $250,000 second prize for its artificial photosynthesis system. The Nolux system – whose name means “no light” – grows plant and fungal-based foods in a dark chamber using acetate to chemically stimulate photosynthesis without light, a capability that could prove valuable in space with limited access to sunlight.
Some members of the Nolux team are now commercializing select aspects of the technology developed during the challenge. These efforts are being pursued through a newly incorporated company focused on refining the technology and exploring market applications.
A competition inspired by NASA’s Deep Space Food Challenge will open this fall.

NASA has demonstrated a breakthrough in 3D-printable high-temperature materials that could lead to stronger, more durable parts for airplanes and spacecraft. Credit: NASA/Jordan Salkin NASA’s Inventions and Contributions Board (ICB) has awarded Commercial Invention of the Year to NASA Glenn Research Center’s GRX-810: A 3D Printable Alloy Designed for Extreme Environments.
NASA Alloy GRX–810, an oxide dispersion strengthened (ODS) alloy, can endure temperatures over 2,000 degrees Fahrenheit. It is more malleable and can survive more than 1,000 times longer than existing state-of-the-art alloys. This new alloy can be used to build aerospace parts for high-temperature applications, like those inside aircraft and rocket engines, because ODS alloys can withstand harsher conditions before reaching their breaking point.
The NASA Glenn team of inventors includes Dr. Timothy Smith (co-lead), Dr. Christopher Kantzos (co-lead), Robert Carter, and Dr. Michael Kulis.
Four American companies have been granted co-exclusive licenses to produce and market GRX-810 material. All four have replicated NASA Glenn’s patented process and are selling fully coated materials. This benefits the United States economy as a return on investment of taxpayer dollars.

Additionally, the ICB selected NASA Glenn’s High-Rate Delay Tolerant Networking (HDTN) project for an honorable mention in the Software of the Year category. HDTN is a protocol suite that extends terrestrial internet principles to the space environment, creating a high-speed data transfer path for spacecraft and different communication systems. It is an optimized version of the DTN standard for high-rate radio frequency and optical links.
The ICB reviews and recommends awards for significant scientific and technical contributions to the agency’s aeronautical and space activities. These awards recognize technologies that not only advance NASA’s mission but also benefit the public through commercialization.

On Tuesday, March 4, 2025, technicians at NASA’s Glenn Research Center in Cleveland help lower student experiments in the 2.2 Second Drop Tower. Credit: NASA/Jef Janis Nineteen teams of students from across the nation in grades 8-12 worked for months in classrooms, labs, basements, and garages for the opportunity to test their projects at NASA’s Glenn Research Center in Cleveland. This spring, the teams’ hard work was put to the test in the 2.2 Second Drop Tower facility at NASA Glenn.
The “2025 Drop Tower Challenge: Paddle Wheel” invited teams to design and build paddle wheels that rotate in water during free fall. The wheels could not rotate by mechanical means. A better understanding of fluid behavior in microgravity could improve spacecraft systems for cooling, life support, and propellants.
On Thursday, May 6, 2025, NASA Glenn Research Center technicians — left to right, John Doehne, Jason West, and Moses Brown — prepare the 2.2. Second Drop Tower for testing student experiments during the 2025 Drop Tower Challenge. Credit: NASA/Jef Janis Based on test performance, analyses, reports, the students’ approach to the challenge, and more, the following teams have been identified as the winners:
First Place: Arth Murarka, Umar Khan, Ishaan Joshi, Alden Al-Mehdi, Rohnin Qureshi, and Omy Gokul (advised by David Dutton), Bellarmine College Preparatory, San Jose, California Second Place: Emma Lai, Keaton Dean, and Oliver Lai (advised by Stephen Lai), Houston, Texas Third Place: Chloe Benner, Ananya Bhatt, and Surabhi Gupta (advised by SueEllen Thomas), Pennridge High School, Perkasie, Pennsylvania “We’re impressed with the variety of designs students submitted for testing in Glenn’s drop tower,” said Nancy Hall, co-lead for the 2025 Drop Tower Challenge. “The teams showed significant creativity and background research through their paddle wheel designs and analysis of results.”
Students from Bellarmine College Preparatory shared how they navigated through the process to earn first place. Using NASA guidelines and resources available to assist students with the challenge, the team submitted a research proposal, including two 3D designs. Learning their team was selected, they reviewed feedback from the NASA staff and set to work.

Credit: Courtesy of Bellarmine College Preparatory To start, students stressed that they conducted a large amount of research and testing of materials to use in their paddle wheels before deciding on the final design.
“I learned that something doesn’t need to be super expensive or complex to work,” said student Umar Khan. “We found that white board sheets or packing peanuts — just household items — can be effective [in the design].”
Student Arth Murarka added, “Our original design looks a lot different from the final.”
Bellarmine staff member and team advisor David Dutton helped the students get organized in the beginning of the process, but said they worked independently through much of the project.

NASA technicians then tested how the paddle wheels performed in the drop tower, which is used for microgravity experiments.
Students said they studied concepts including capillary physics and fluid dynamics. They also learned how to write a research paper, which they said they will appreciate in the future.
The team dedicated a lot of time to the project, meeting daily and on weekends.
“We learned a lot of useful skills and had a lot of fun,” Murarka said. “It was definitely worth it.”
