NASA repurposes Gateway core for a nuclear-powered Mars mission
NASA plans to pause Lunar Gateway work and repurpose its Power and Propulsion Element into SR-1 Freedom, a nuclear-electric propulsion demonstration using a uranium-fueled fission reactor and electric thrusters to reach Mars by the 2028 launch window. The mission will also deploy three Ingenuity-like helicopters (Skyfall) on Mars to scout landing sites, with the mothership’s fate to be decided after arrival. The plan faces significant technical, safety, and certification hurdles, and no cost figure has been disclosed.
