NASA's Space Reactor-1 Freedom aims for Mars with a trio of scout helicopters

NASA plans to launch Space Reactor-1 Freedom in 2028, the first nuclear-powered interplanetary spacecraft, using nuclear electric propulsion to reach Mars and carry three Skyfall scout helicopters to map terrain and locate subsurface water ice for future crewed missions; this mission sits within NASA’s broader exploration reboot, which pauses Gateway to focus on a permanent lunar base while keeping Dragonfly to Titan and Rosalind Franklin Rover to Mars on track.

NASA maps a lunar base push while eyeing a nuclear-powered Mars mission

NASA’s new leadership unveiled an ambitious plan: fast‑track a permanent Moon base by repurposing Gateway assets and increasing robotic landers, pause the Gateway project, and accelerate a nuclear electric propulsion–powered Mars mission by 2028, while weighing funding, timelines, and private‑sector collaboration as Artemis progresses toward returning humans to the Moon.

NASA targets nuclear-electric propulsion with SR-1 Freedom, rebooting Voyager-era power talk

NASA is pursuing Space Reactor-1 Freedom, a 20-kilowatt fission reactor to power a nuclear-electric propulsion system for an interplanetary mission planned for 2028; the NEP approach would use reactor-generated electricity to run an ion engine, a shift from RTGs that have powered Voyager for decades. The project sits in NASA's long history of space nuclear power (SNAP, SNAP-10A, DRACO) with safety and regulatory hurdles still in play; Voyager probes remain RTG-powered and active.

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.

NASA bets on nuclear-electric power for a 2028 Mars mission

NASA Administrator Jared Isaacman and agency leaders announced Space Reactor-1 Freedom, a nuclear-electric propulsion mission to Mars set for December 2028 that repurposes the Lunar Gateway’s Power and Propulsion Element (PPE) to run xenon ion thrusters and carry three Ingenuity-class helicopters for surface scouting. The spacecraft will host a 20+ kilowatt fission reactor with a closed Brayton power cycle, using solar panels to supply electricity when the reactor is off. The mission aims to demonstrate Nuclear Electric Propulsion as a pathfinder for high‑power, long‑duration journeys and to inform future missions, with readiness milestones in 2027–2028 and a plan to arrive near Mars about a year after launch; it could spawn further concept missions like Lunar Reactor-1 and invite commercial partners and student payloads.

NASA charts $20B lunar base plan and nuclear Mars mission

NASA unveils a seven-year, $20 billion overhaul to build a surface lunar base with robotic prep, repurpose the Lunar Gateway for surface infrastructure (pausing its orbital role), and advance a nuclear-powered Mars mission via Space Reactor 1 Freedom by 2028, including a Mars helicopter test; the move reshapes Artemis and heightens competition with China.

NASA Bets on Nuclear-Powered Skyfall Helicopters for Mars by 2028

NASA unveiled the Skyfall concept: six small helicopter scouts would ride to Mars on a nuclear-electric propulsion spacecraft called Space Reactor-1 (SR-1) Freedom, targeting a 2028 launch. The mission would demonstrate onboard fission power powering efficient electric thrusters, enabling surface reconnaissance and data collection to aid future crewed Mars missions and broader outer-planet exploration, while shaping a regulatory and industrial base for nuclear power in space.
