Credits: NASA NASA is requesting feedback from American companies on the next phase of its commercial space stations strategy to ensure a seamless transition of activities in low Earth orbit from the International Space Station.
The agency released a draft Phase 2 Announcement for Partnership Proposals (AFPP) Friday, asking for feedback from industry partners by 1 p.m. EDT Friday, Sept. 12. NASA will hold an informational industry briefing on Monday, Sept. 8, to provide a top-level summary of the documents and expectations.
Under the direction of acting NASA Administrator Sean Duffy, the agency reassessed the commercial space stations acquisition strategy to ensure mission continuity, affordability, and national alignment, and to reduce the potential for a gap of a crew-capable platform in low Earth orbit.
“NASA has led in low Earth orbit for 25 years and counting. Now, as we prepare for deorbiting the International Space Station in 2030, we’re calling on our commercial space partners to maintain this historic human presence,” Duffy said. “The American space industry is booming. Insight from these innovative companies will be invaluable as we work to chart the next phase of commercial space stations.”
In Phase 2, NASA intends to support industry’s design and demonstration of commercial stations through multiple funded Space Act Agreements, selected through a full and open competition.
“NASA is committed to continuing our partnership with industry to ensure a continuity in low Earth orbit,” said Angela Hart, manager, Commercial Low Earth Orbit Development Program at NASA’s Johnson Space Center in Houston. “The work done under our Phase 1 contracts and agreements have put us in a prime position to be successful for this next funded Space Act Agreement phase. By leveraging these agreements, we provide additional flexibility to our commercial partners to define the best path forward to provide NASA a safe and affordable crewed demonstration.”
The Phase 2 agreements are expected to include funded milestones leading to critical design review readiness and an in-space crewed demonstration of four crew members for a minimum of 30 days. Agreements are expected to include up to a five-year period of performance.
The agency’s phased approach will culminate in a follow-on Phase 3 using Federal Acquisition Regulation-based contract(s) to purchase station services through a full and open competition. This final phase will also provide formal design acceptance and certification, ensuring the commercial stations meet NASA’s safety requirements.
NASA remains committed to fostering innovation and collaboration within the American space industry.
The agency’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost, enabling the agency to focus on the next step in humanity’s exploration of the solar system while also continuing to use low Earth orbit as an ideal environment for training and a proving ground for Artemis missions to the Moon and Mars.

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.

As part of the agency’s initiative to return humanity to the Moon and eventually send the first astronaut – an American – to Mars, NASA is surveying industry for interest and feedback on a fission surface power system, through a Request for Information issued Thursday.
Earlier this month, NASA declared its intent to put a nuclear reactor on the Moon by the mid-2030s to support lunar exploration, provide power generation on Mars, and strengthen national security in space.
“Today’s call for industry input is an important step toward engaging the commercial space industry in powering the lunar economy and enabling future human exploration on Mars,” said Steve Sinacore, Fission Surface Power program executive at NASA’s Glenn Research Center in Cleveland. “Developing a safe, reliable, and efficient power supply is key to unlocking the future of human space exploration and ensuring America retains its dominance in space.”
Building on its previous work, NASA will work with industry to design a fission surface power system that would provide at least 100 kilowatts of electrical power, have a mass allocation of less than 15 metric tons, and use a closed Brayton cycle power conversion system, which converts heat to electricity.
NASA’s new Fission Surface Power effort builds on more than 60 years of agency experience in exploration technology. In 2022, NASA awarded three contracts for fission surface power system concepts for the Moon. In addition, NASA has used nuclear power sources in spacecraft and rovers over the years.
The size, weight, and power capability of fission systems make them an effective continuous power supply regardless of location. Additionally, a nuclear reactor could be placed in lunar regions where sunlight cannot reach and could sustain nights on the Moon which can last more than 14 Earth days near the poles.
Nuclear power is a key element for NASA’s Artemis missions and supporting a robust lunar economy. The Request for Information invites innovators to contribute to this effort, allowing NASA to access industry expertise and bolstering American ingenuity.
Responses to the Request for Information are due Thursday, Aug. 21, and could be used to finalize a potential opportunity later this year.
The Fission Surface Power effort is managed through NASA Glenn. The power system development is funded by the agency’s Exploration Systems Development Mission Directorate Moon to Mars Program.
