LOS ANGELES, Oct. 20 (Xinhua) -- NASA on Tuesday provided an update on the development of crewed and robotic lunar rovers to support its planned Moon Base initiative, highlighting efforts to develop the surface mobility capabilities needed for future exploration and sustained human operations on the Moon. NASA's Volatiles Investigating Polar Exploration Rover is scheduled to embark on a mission to the lunar South Pole region in 2027 to explore permanently shadowed craters in search of water and other potentially valuable resources that could support sustainable lunar exploration. The rover will be delivered to the lunar surface by Blue Origin's Blue Moon Mark 1 lander and is expected to travel more than 30 kilometers, collecting data on local temperatures, lighting conditions and terrain. NASA said the data could help scientists better understand the origin and distribution of water on the Moon and assess how lunar resources might be used to support future exploration.
