The first humans to Mars might someday ride a rocket propelled by a nuclear reactor to their destination. But before that can happen, nuclear thermal propulsion (NTP) technologies still have quite a way to go before we could blast astronauts through space on a nuclear rocket.
However, earlier this month, General Atomics Electromagnetic Systems (GA-EMS), in collaboration with NASA, achieved an important milestone on the road to using NTP rockets. At NASA's Marshall Space Flight Center in Alabama, General Atomics tested a new NTP reactor fuel to find out if the fuel could function in the extreme conditions of space.
