Live coverage: NASA confirms successful first flight of Mars helicopter

Japan’s Hayabusa 2 spacecraft deployed two target markers Monday above asteroid Ryugu in a rehearsal for the release of the mission’s final landing robot next month.

Blue Origin has partnered with Lockheed Martin and Northrop Grumman to build elements of the company’s human-rated lunar lander, and Draper will lead development of the lander’s avionics and guidance systems, with an aim to be ready to land a crew on the moon by 2024, company founder Jeff Bezos announced Tuesday.
