Watch the Falcon 9 light its engines for a static test fire (members only)

Two-and-a-half days after launch from Virginia, a Northrop Grumman Cygnus supply ship arrived at the International Space Station Tuesday with nearly 7,500 pounds of cargo. Capture with the station’s robotic arm occurred at 4:05 a.m. EST (0905 GMT).

Succeeding on a one-shot launch attempt before Hurricane Irma shuts down the Cape Canaveral spaceport, a SpaceX Falcon 9 rocket thundered into orbit Thursday with the U.S. Air Force’s X-37B spaceplane, a reusable robotic mini-shuttle that could stay aloft for years with clandestine on-board experiments.

Running through a practice countdown and hold-down engine firing at NASA’s Kennedy Space Center, a SpaceX Falcon 9 rocket passed a key checkpoint Thursday ahead of liftoff next week with the U.S. Air Force’s fifth X-37B spaceplane flight, a mission that will come with several firsts.
