Should private companies be responsible for testing nuclear power technology for use in space?
NASA and the Department of Energy signed a formal memorandum of understanding on October 8 to coordinate efforts in space nuclear research, fuel production, and operations. This partnership aims to accelerate American leadership in nuclear-powered space systems beginning November 1.
Why it matters
The collaboration seeks to implement objectives from a December 2025 executive order signed by President Donald Trump, which directed the development of a lunar surface reactor. By streamlining research and launch integration, the agreement supports future mission goals like the NASA SR-1 Freedom launch.
The agreement encompasses diverse technical activities including research, fuel production, testing, launch integration, and operations. Sandia National Laboratories has previously provided independent validation for launch safety analysis involving nuclear payloads.
The players
NASA
The United States government agency responsible for the nation's civilian space program and aeronautics research.
Department of Energy
The federal agency that oversees the nation's nuclear weapons program, energy policy, and nuclear reactor research.
President Donald Trump
The current President of the United States who issued a 2025 executive order directing the creation of a lunar surface reactor.
City Labs
A Miami-based company specializing in betavoltaic batteries that launched a nuclear-powered payload in 2026.
Sandia National Laboratories
A federally funded research and development center that provides safety validation for complex nuclear and energy systems.
The details
The initiative builds on recent developments in private sector nuclear technology, such as the July 2026 launch of a tritium-powered betavoltaic payload by City Labs. The partnership will help standardize the frameworks required for future systems like the LR-1 fission surface power reactor intended for a lunar base.
Timeline
September 30, 2025: The FAA issued launch authorization for the City Labs mission.
December 2025: President Donald Trump signed an executive order regarding space nuclear power.
July 7, 2026: City Labs launched a tritium-powered BOHR payload.
October 8, 2026: NASA and the Department of Energy signed a memorandum of understanding.
November 1, 2026: The memorandum of understanding takes official effect.
The Big Picture
This agreement marks a structural shift toward consolidating federal resources to meet the lunar infrastructure goals set by the 2025 executive order regarding space nuclear power. It replaces disparate agency research efforts with a unified framework for fission surface power systems.
While the immediate impact is institutional, the development of lunar surface reactors and propulsion systems could eventually lower the costs of deep-space exploration. These advancements may lead to more frequent mission cycles and the commercialization of lunar resource extraction.
The takeaway
The formalization of this partnership underscores a transition from conceptual planning to operational execution for space-based nuclear energy. Readers should watch for updates on the 2028 NASA SR-1 Freedom mission as a key test for these integrated technologies.
What happens next
NASA SR-1 Freedom is scheduled to launch in 2028.
