Watch the Falcon 9 launch from pad 39A

Russian cosmonauts aboard the International Space Station commanded an approaching unpiloted Soyuz spacecraft to abort its docking Saturday after the ship’s automated rendezvous system ran into trouble, leaving ground teams assessing what went wrong and whether to attempt another link-up in orbit.

SpaceX’s Dragon cargo craft departed the International Space Station on Wednesday at 9:19 a.m. EDT (1319 GMT), concluding the commercial spaceship’s eighth visit to the complex. Splashdown in the Pacific Ocean occurred at 2:55 p.m. EDT (1855 GMT).

After a 22-day stay at the International Space Station, an Orbital ATK Cygnus supply ship is set for departure Wednesday en route to a higher orbit for release of 14 CubeSats for commercial weather monitoring and technology demonstrations. The robotic Cygnus spacecraft is scheduled for release from the station’s robotic arm at 8:10 a.m. EST (1310 GMT) Wednesday.
