Europe Advances Space Nuclear Power Research, Targeting Lunar and Mars Missions
The European Space Agency (ESA) is accelerating its assessment of nuclear energy applications in deep-space missions, focusing on using small nuclear reactors to power spacecraft electric propulsion systems, as well as providing stable energy for future fixed lunar surface facilities and subsequent Mars missions. Existing space missions primarily rely on chemical fuels and solar panels. The former is limited by the amount of propellant that can be carried, while the latter suffers from declining power generation efficiency as spacecraft move farther from the Sun. ESA believes that nuclear power systems could compensate for the shortcomings of both approaches, particularly in long-duration lunar operations and deeper space exploration. ESA completed a nuclear thermal propulsion study last year. In March this year, the agency...

U.S. Plans to Launch Nuclear Fission-Powered Spacecraft to Fly by Mars by End of 2028
The National Aeronautics and Space Administration (NASA) is advancing the Space Reactor-1 "Freedom" (SR-1 Freedom) mission, with the goal of launching a nuclear fission-powered spacecraft by the end of 2028 to validate deep-space nuclear electric propulsion technology. According to existing mission documentation, the mission plans to fly by Mars in 2029 and deploy the SkyFall payload. The SR-1 Freedom is neither a fusion spacecraft nor a crewed Mars vehicle. Its core experiment is to operate a small uranium fission reactor, an energy conversion system, and Hall-effect thrusters in coordination beyond Earth orbit, accumulating engineering data for future higher-power deep-space missions...
