Space Reactor 1 (SR-1) Freedom Spacecraft:
NASA has revamped the Artemis programme, scrapping the Lunar Gateway plan and prioritizing a moon base and Mars missions.It also announced Space Reactor 1 Freedom, a nuclear-powered spacecraft to be launched by 2028.
- Space Reactor 1 Freedom is set to be the first interplanetary spacecraft powered by a nuclear fission reactor, marking a transition from experimental laboratory research to active deep-space operations. It is a pathfinder spacecraft utilizing Nuclear Electric Propulsion (NEP).
- The mission was officially announced by NASA.
- Aim:
- To prove the viability of advanced nuclear electric propulsion for long-duration, deep-space travel.
- To deliver the Skyfall payload—a fleet of robotic helicopters—to the Martian surface to scout for water ice and human landing sites.
- To retire flight risks and activate the industrial supply chain for future nuclear-powered missions to the outer solar system.
- It will utilize the Power and Propulsion Element (PPE) originally designed for the now-paused Lunar Gateway station.
- Features an onboard reactor that splits uranium atoms to provide a continuous, high-output power source independent of sunlight.
- Carries three (or up to six, per some reports) Ingenuity-class helicopters equipped with ground-penetrating radar and high-resolution cameras.
- Launch Date: Scheduled for launch in December 2028.
