NASA aims to launch Mars rover twin in 2020

SAN FRANCISCO, Dec 5: NASA plans to follow up its Mars rover Curiosity mission with a duplicate rover that could collect and store samples for return to Earth, the agency’s lead scientist said on Tuesday. The new rover will use spare parts and engineering models developed for Curiosity, which is four months into a planned $2.5 billion mission on Mars to look for habitats that could have supported microbial life.
