Researchers at NASA and the Department of Energy recently tested key technologies for developing a nuclear fission reactor that could power a human outpost on the moon or Mars. 

 

The tests prove that the agencies could build a "safe, reliable, and efficient" system by 2020, the year NASA plans to return humans to the moon.

A fission reactor works by splitting atoms and releasing energy in the form of heat, which is converted into electricity. The idea for using nuclear power in space dates back to the late 1950s, when they were considered for providing propulsion through Project Orion. 

 

In the 1960s a series of compact, experimental space nuclear reactors were developed by NASA under the Systems Nuclear Auxiliary Power program. But public safety concerns and an international treaty banning nuclear power in space stopped development.
