NASA is accelerating its plans for a nuclear reactor on the moon.

Acting NASA Administrator Sean Duffy has directed the agency to fast-track plans to put a nuclear reactor on the moon.

NASA’s new directive aims to power the Moon’s shadowy regions—but skeptics wonder what’s really behind the rush.
