Live coverage: Soyuz crew lands in Kazakhstan

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.

SpaceX test-fired a Falcon 9 rocket Wednesday afternoon at NASA’s Kennedy Space Center in Florida, clearing a major hurdle before it launches Saturday night — weather permitting — with a four-person crew heading for the International Space Station.

A Soyuz rocket is scheduled for liftoff Friday from the Vostochny Cosmodrome, Russia’s newest launch site, with 33 satellites from 12 countries on-board to collect weather data and test new space technology.
