NASA is deploying The Mars Helicopter, "a small, autonomous rotorcraft, [that] will travel with the agency’s Mars 2020 rover mission, currently scheduled to launch in July 2020," the agency announced in a press release.

The problem facing NASA engineers: How to overcome Mars’ relatively thin atmosphere, which would doom any conventional craft. Proving this concept could help with future human exploration of the planet.
