NASA @NASA 8:31 PM · Mar 24, 2026NASA is advancing nuclear power and propulsion in space to accomplish President Trump’s national space objectives.With SR-1 Freedom, launching in 2028, we will demonstrate nuclear electric propulsion and deliver SkyFall helicopters to Mars.In collaboration with @Energy, these capabilities are key to future missions to Mars and beyond.A new chapter of deep space exploration begins. 🚀
NASA Administrator Jared Isaacman @NASAAdmin 8:31 PM · Mar 24, 2026NASA is building SR-1 Freedom, a nuclear electric propulsion spacecraft, launching to Mars in 2028. We are proud to announce this during the 250th year of the United States, the mission’s name reflects the spirit of American innovation and exploration. This mission will bring America’s nuclear power capabilities to space and deliver the Skyfall payload of Ingenuity class helicopters to explore the Red Planet. Nuclear power and propulsion will be the key to undertaking crewed missions to Mars and exploring the outer solar system. Space Reactor-1 (SR-1) Freedom will make the next giant leap and accomplish a key component of President Trump’s National Space Policy, bringing nuclear to space alongside @Energy.

SR-1 Freedom: NASA plans to launch its first nuclear-powered Mars spacecraft in 2028By Mrigakshi Dixit Space Apr 23, 2026 08:09 AM ESTSlated for a December 2028 launch, it will be the first interplanetary spacecraft powered by a nuclear fission reactor.(...) To ensure it hits the 2028 launch window, NASA is intentionally limiting the spacecraft’s scope, pairing a single new nuclear reactor system with proven, existing technologies rather than attempting a total design overhaul.Isaacman characterizes the SR-1 Freedom as a “70 percent solution,” designed primarily to demonstrate the viability of nuclear propulsion rather than serve as a final, perfect model. The spacecraft will use a 20-kWe reactor fueled by HALEU (High-Assay Low-Enriched Uranium) to power advanced electric thrusters.It is expected to be activated within 48 hours of launch, beginning its year-long journey to Mars. The system will use a closed Brayton cycle to convert heat into electricity, supported by heat pipes and a boron carbide radiation shield. To manage thermal loads and propulsion, the craft will employ lightweight composite-titanium radiators and an advanced 48-kW electric propulsion system, which also doubles as the primary spacecraft bus for communications and power distribution.Skyfall missionIts primary mission? To act as a mother ship for Skyfall, a triad of “Ingenuity-style” helicopters. Equipped with ground-penetrating radar, the drone swarm will survey potential landing sites and identify ice deposits, providing the critical data needed to verify the terrain for upcoming crewed missions.NASA has yet to determine the fate of SR-1 Freedom following the Skyfall mission. Officials are currently weighing whether the reactor-driven craft will perform a simple flyby or attempt to enter Mars orbit once its primary cargo has been delivered.“The team is still looking at exploring the opportunities. Once we drop off Skyfall what do we do with SR-1 Freedom?” said Steve Sinacore, NASA’s fission surface power program executive. (...)
