Sean Duffy wants to fast-track putting a 100kw nuclear reactor on the moon, according to a directive he sent out Thursday. It would help win the "space race."

NASA's acting administrator, Sean Duffy, plans to accelerate the construction of a nuclear reactor that could be used on the moon and alter the way NASA will partner with industry to replace the aging International Space Station.

NASA is ready to send nuclear reactors to the Moon. The goal is to have a working reactor by 2030. NASA boss Sean Duffy said the U.S. is racing China to the Moon. Planting reactors is smarter than just planting flags.
