NASA has unveiled PROMISE, a new nuclear-powered lunar rover built using spare components and engineering test hardware from its Curiosity and Perseverance Mars rovers! Announced at NASA's MAX POWER event at Kennedy Space Center on Nov. 7, 2026, the PROMISE (Polar Rover for Observation, Mapping, and In-Situ Exploration) mission will explore the moon's south pole, searching for water ice and other resources that could support future astronauts and NASA's planned Moon Base.
