Live coverage: Delta 2 launches

A three-man crew closed out a 196-day expedition in orbit late Wednesday with a parachute-assisted landing on the steppe of Kazakhstan aboard the Russian Soyuz MS-17 spacecraft. NASA astronaut Chris Cassidy, Soyuz commander Anatoly Ivanishin, and flight engineer Ivan Vagner undocked from the International Space Station at 7:32 p.m. EDT (2332 GMT) Wednesday, and the trio landed at 10:54 p.m. EDT (0254 GMT).

SpaceX has launched a Falcon 9 rocket with a previously-flown first stage booster carrying the SES 12 communications satellite, an all-electric, multi-band video and data relay platform to serve the Asia-Pacific region. Liftoff from Cape Canaveral occurred at 12:45 a.m. EDT (0445 GMT), and SpaceX did not plan to recover the first stage.

The launch of a United Launch Alliance Delta 4-Heavy rocket from Cape Canaveral was aborted three seconds before a planned liftoff at 3:28 a.m. EDT (0728 GMT). The rocket was set to loft a classified payload for the National Reconnaissance Office, the U.S. government’s spy satellite agency.
