Isaacman Backs Fission Spacecraft at INL, Vowing U.S. Will Win 2nd and 3rd Space Races

Summary
Idaho Falls marked Jared Isaacman’s first Idaho visit as NASA administrator, where he said the U.S. will win the next races to the moon, Mars and deeper into the solar system.
Fission-powered spacecraft were the centerpiece of his pitch: Isaacman said routine missions to places like Enceladus and Uranus require more power, longer endurance and faster travel than current systems can provide.
INL’s role framed the visit, with Isaacman touring microreactor work involving Radiant, Antares and Deployable Energy before appearing with Gov. Brad Little, Rep. Mike Simpson and Deputy Energy Secretary James Danly.
The message builds on NASA’s broader push with DOE and industry to develop nuclear systems for deep-space missions, including reactor plans tied to a 2028 Mars effort and a 2030 moon base.
With private startups racing to power the Moon by 2030, who will ultimately control the first off-world nuclear grid?
Could a compact nuclear reactor built in just 155 days be the secret to reaching Mars in only 45 days?
Launching dormant reactors into orbit sounds brilliant, but what happens if a commercial rocket fails before activation?
The Nuclear-Powered Leap: NASA’s 2028 Mars Mission, 2030 Moon Base, and the New Space Race with China
Overview
NASA’s upcoming SR-1 Freedom mission, launching in 2028, will be the first to use a nuclear fission reactor for interplanetary travel, marking a major shift from traditional propulsion. By pairing new nuclear technology with proven systems, NASA aims for immediate operational success and to break the cycle of failed space nuclear projects. The mission will set regulatory precedents and inform the development of the Lunar Reactor-1 for the Moon base by 2030. This nuclear push is part of a broader strategy to secure American leadership in space, accelerate lunar infrastructure, and respond to rising competition from China and Russia.
