NASA Plans Nuclear-Powered Mars Mission with Helicopter Deployment for 2028
NASA announced on March 24 its intention to launch a nuclear fission-powered spacecraft, Space Reactor-1 (SR-1) Freedom, targeting Mars by late 2028. This mission aims to be the first U.S. use of nuclear propulsion beyond Earth's orbit, deploying three helicopters to scout for water and landing sites. The effort supports future human exploration and could extend to other solar system destinations. NASA Administrator Jared Isaacman highlighted its role in enabling sustained deep-space missions, while scientists express concerns about the helicopters' scientific capabilities. The project also informs development of a lunar power system for a planned moon base.
Key facts
- NASA targets late 2028 for launching SR-1 Freedom, a nuclear fission-powered spacecraft to Mars
- The mission will deploy three helicopters to search for underground water and potential human landing sites
- Nuclear fission propulsion has not been tested by the U.S. for space travel since the 1960s
- NASA's Artemis program adjustments include delaying crewed moon landings to Artemis 4 in 2028
- The project supports development of Lunar Reactor-1, a fission system for a future moon base
