NASA Glenn Research Center - Fission Surface Power Project
NASA is working with the Department of Energy and industry to design and build a fission surface power system that will provide 40 kilowatts of power – enough to continuously run 30 households for 10 years. A future lunar demonstration will pave the way for applications on Earth and even base camps on the Moon and Mars.
