NASA bets $2B on nuclear-powered spaceship for Mars mission

By PulseAugur Editorial · [1 sources] ·

NASA is moving forward with plans to develop Space Reactor-1 Freedom (SR-1), its first nuclear-reactor-powered interplanetary spacecraft, with a target of an uncrewed mission to Mars by late 2028. This technology aims to significantly reduce travel time and astronaut exposure to cosmic radiation on deep-space missions. While previous US programs have been canceled due to cost and safety concerns, NASA is now investing $2 billion in nuclear electric propulsion, which uses a low-thrust, high-efficiency system. The SR-1 reactor, designed to be at least 20 kilowatts, will be activated two days after launch to ensure safety. AI

    Nuclear-powered spaceships

    Just before the Artemis II crew began its historic slingshot around the moon this past April, NASA announced plans to build Space Reactor-1 Freedom. SR-1, the first-ever nuclear-reactor-­powered interplanetary spacecraft, is meant to fly an uncrewed mission to Mars by the end of …
