NASA Unveils Plans for Nuclear-Powered Mars Mission by 2028
NASA announces Space Reactor-1 Freedom, a nuclear-powered spacecraft set to launch to Mars before the end of 2028, aiming to demonstrate advanced nuclear electric propulsion in deep space.
NASA has announced plans to launch Space Reactor-1 Freedom, a nuclear-powered spacecraft, to Mars before the end of 2028. The mission aims to demonstrate advanced nuclear electric propulsion in deep space, potentially enabling high-power missions beyond Jupiter, where solar arrays are less effective.
The announcement was made during NASA's Ignition news conference on March 24, 2026, where the agency also outlined a revamped approach to lunar exploration. Plans include sending astronaut missions to the lunar surface every six months, increasing deployment of lunar rovers and technology demonstrations, and developing infrastructure for a habitable Moon base to support regular crewed missions.
Additionally, NASA intends to develop a new module for the International Space Station, which will eventually detach to form a new U.S. space station in Earth orbit. The agency also plans to pause development of the Lunar Gateway to focus on establishing a permanent human habitat on the lunar surface.
Upon reaching Mars, Space Reactor-1 Freedom will deploy Skyfall, a payload of helicopters similar to NASA's Ingenuity, which performed a successful test flight on Mars in April 2021. NASA states that Freedom will establish flight heritage nuclear hardware, set regulatory and launch precedents, and activate the industrial base for future fission power systems across propulsion, surface, and long-duration missions.
NASA Associate Administrator Amit Kshatriya emphasized the agency's strategic shift: "On the Moon, we are shifting to a focused, phased architecture that builds capability landing by landing, incrementally, and in alignment with our industrial and international partners."
He also highlighted the importance of nuclear propulsion: "With Space Reactor-1 Freedom, we are finally putting nuclear propulsion on a trajectory out of the laboratory and into deep space."
This initiative aligns with NASA's broader goals of sustained exploration and the development of infrastructure to support long-term human presence on the Moon and Mars.
