NASA may send a backup, nuclear-powered Mars rover to the Moon

NASA officials said Tuesday that they are seriously considering sending the full-scale engineering model of the Perseverance rover, which is currently housed at the Jet Propulsion Laboratory in California, to the Moon to expedite their efforts to explore the south pole region. The car-sized rover nicknamed "Promise," which serves as a testbed for Perseverance and was not otherwise planned for a launch, would land equipped with a multi-mission radioisotope thermoelectric generator (MMRTG) to power it across difficult terrain and through the lunar night. NASA's other rovers primarily operate on solar power. "We are thinking very hard right now about sending Promise to the Moon," NASA Administrator Jared Isaacman said Tuesday during a monthly update on the agency's plans to build a Moon base.Read full article Comments
