NASA’s next Mars rover might have a companion drone

NASA has been able to gather unprecedented amounts of information on Mars using a single, land-bound drone, so just imagine what it could do with a flying drone. It sounds like NASA has already started imagining it, and it must like what it sees, because there’s a good chance that the Mars 2020 rover will come with a flying companion drone that will scout out potential points of interest for the land-bound rover to explore.
