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 has set a 2030 deadline to build a 100-kilowatt nuclear reactor on the moon. It’s an ambitious but potentially achievable goal that could transform space exploration, experts tell WIRED.

The acceleration of nuclear development is part of the Trump administration’s efforts to focus NASA on human spaceflight. A reactor would be useful for long-term stays on the moon.
