"We're in a race to the Moon, in a race with China to the Moon. And to have a base on the Moon, we need energy," Duffy told reporters (via Space.com) when asked about his plan to build a 100-kilowatt nuclear reactor on the Moon by 2030.

The National Aeronautics and Space Administration plans to build a nuclear reactor on the moon before China and Russia.

The Trump administration wants a nuclear reactor on the moon by the end of the decade in a bid to beat Russia and China to colonization.
