US Tests Nuclear Power System To Sustain Astronauts On Mars (reuters.com)

Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface on Mars have been successful and a full-power run is scheduled for March, officials said on Thursday. Reuters reports: National Aeronautics and Space Administration and U.S. Department of Energy officials, at a Las Vegas news conference, detailed the development of the nuclear fission system under NASA's Kilopower project. Months-long testing began in November at the energy department's Nevada National Security Site, with an eye toward providing energy for future astronaut and robotic missions in space and on the surface of Mars, the moon or other solar system destinations. A key hurdle for any long-term colony on the surface of a planet or moon, as opposed to NASA's six short lunar surface visits from 1969 to 1972, is possessing a power source strong enough to sustain a base but small and light enough to allow for transport through space. NASA's prototype power system uses a uranium-235 reactor core roughly the size of a paper towel roll. The technology could power habitats and life-support systems, enable astronauts to mine resources, recharge rovers and run processing equipment to transform resources such as ice on the planet into oxygen, water and fuel. It could also potentially augment electrically powered spacecraft propulsion systems on missions to the outer planets.

    I don't understand why they can't use hydro, wind or solar. Does NASA have to subsidize Big Oil and the nuclear industry? Damn you Trump, Damn you! ;)

    This reactor is amazing - it's completely passive. It's self-regulated by thermal expansion of its fuel. There are no moving parts (apart from a heat engine), the reactor is started by removing one control rod and then it just runs on until fuel is exhausted.https://hardware.slashdot.org/story/18/01/18/2148243/us-tests-nuclear-power-system-to-sustain-astronauts-on-mars#
