NASA Successfully Tests Nuclear Reactor to Power Future Moon Bases

Gone Fission : See it bigger. John MacNeil

From Popular Science:

For a while now, NASA has been planning to use a nuclear fission reactor to power future bases on the Moon and Mars. They have now finally begun testing a Stirling engine-based system, subjecting it to simulated extraterrestrial conditions to examine how it would fare as a lunar power generator.

The fission reactor uses a sodium-potassium liquid metal mixture to transfer heat to a Stirling engine, which then uses gas pressure for electricity conversion. Testing has been successful so far, as researchers have been able to generate a constant 2.3 kilowatts of power from the engine, using a non-nuclear heat source. With the full nuclear reactor running, their goal is to produce 40 kilowatts of power.
