Why NASA wants to build a nuclear reactor on the Moon
Everyone's talking about the Moon. It'll be 50 years this Christmas since Apollo 8 first flew to the Moon – with the crew taking the famous Earthrise photos – and we're close to the 50th anniversary of Apollo 11's first moon landing and moonwalk for Neil Armstrong and Buzz Aldrin. Can we go back? Should we go back? NASA knows we probably have to go back, if only to use the Moon as an off-Earth stepping stone to enable deeper solar system exploration missions, so it's spent years trying to create a nuclear reactor that can be operated there.
