PROMISE on the Moon: NASA weighs sending spare Mars rover to support Artemis

NASA is considering refurbishing the Mars rover PROMISE (Polar Rover for Observation, Mapping, and In-Situ Exploration) for a lunar mission as part of its Artemis program. The RTG-powered rover would serve as an Earth-based testbed on the Moon (likely near the south pole) to aid lunar outpost development, while other CLPS landers carry NASA science payloads to the surface. If repurposed, PROMISE would complement upcoming lunar assets and help test technologies for future crewed missions.
