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.

SpaceX has successfully launched its Falcon-9 rocket carrying the Bangabandhu-1, Bangladesh's first-ever high-orbit communications satellite, and landed it safely on a drone ship in the Atlantic Ocean off the coast of Florida.
