Nuclear reactors in space may sound like something out of science fiction, but they are likely to prove important for powering long-term space missions.

NASA announced plans to build a nuclear reactor on the moon on Tuesday, in an attempt to stay ahead of China and Russia in a new space race. The goal is to have the reactor built before 2030, a timeline set during the Biden administration.

NASA plans to establish a continuous lunar presence by 2030 with a nuclear reactor, crucial for powering habitats and operations during long lunar nights. This initiative supports the Artemis program and addresses the limitations of solar power in shadowed regions.
