Three teams have been picked to design a fission surface power system that NASA could deploy on the moon by the end of the decade, NASA and Idaho National Laboratory announced today. A fission surface power project sponsored by NASA in collaboration with the Department of Energy and INL is targeting the demonstration of a 40-kWe reactor built to operate for at least 10 years on the moon, enabling lunar exploration under NASA’s Artemis program. Twelve-month contracts valued at $5 million each are going to Lockheed Martin (partnered with BWX Technologies and Creare), Westinghouse (partnered with Aerojet Rocketdyne), and IX (a joint venture of Intuitive Machines and X-energy, partnered with Maxar and Boeing).
