The first flight of SpaceX’s Dragon capsule

The head of NASA’s human spaceflight programs has abruptly resigned, announcing his departure from the space agency two days before before he was to chair a crucial readiness review ahead of the launch of the first crewed U.S. space mission in nearly a decade.

SpaceX conducted its first launch from Florida in more than two months Thursday, when a Falcon 9 rocket lifted off from the Kennedy Space Center with the Qatari Es’hail 2 communications satellite at 3:46 p.m. EST (2046 GMT). The Falcon 9’s reused first stage landed on SpaceX’s drone ship in the Atlantic Ocean.

After two successful Falcon Heavy missions in less than 11 weeks, launch fans will likely have to wait until late 2020 for SpaceX’s next Falcon Heavy flight, barring a surprise mission for an unannounced customer.
