NASA's Nuclear Mars Mission Eyes a $2.1B Price Tag and Near-Term Funding
NASA estimates its Space Reactor-1 Freedom nuclear-powered Mars mission would cost about $2.1 billion, with funding planned for fiscal years 2026–2029 and not including the SkyFall science payload; the plan reuses the Gateway’s Power and Propulsion Element, involves the DOE, and targets a late-2028 launch with three helicopters to study Mars.
