Live coverage: NASA confirms successful first flight of Mars helicopter

Testing of a lightweight robotic helicopter designed to fly in the alien atmosphere of Mars has produced encouraging results in recent months, and NASA officials expect to decide soon whether the aerial drone will accompany the agency’s next rover to the red planet set for liftoff in 2020.

An Orbital ATK Cygnus cargo craft departed the International Space Station on Wednesday, heading for a higher orbit to deploy 14 CubeSats and an eventual de-orbit burn to dispose of more than 6,200 pounds of trash and other unneeded equipment packed by the station’s crew.

Ground controllers are running Europe’s ExoMars orbiter through a post-launch checkup a week after its successful liftoff aboard a Proton rocket, and a first look at the probe’s systems has revealed no problems, the mission’s flight director said Tuesday.
