Live coverage: Soyuz crew arrives at International Space Station

The Russian Soyuz MS-03 crew transport spacecraft is launched from the Baikonur Cosmodrome with three passengers on a two-day trek to the International Space Station.

A rocket-transporting railroad car ferried a Proton rocket to its launch pad Friday at the Baikonur Cosmodrome in Kazakhstan for final checkouts and testing before the vehicle’s scheduled June 21 liftoff with the Russian-German Spektr-RG X-ray telescope.

A SpaceX Dragon cargo freighter departed the International Space Station Tuesday for return to Earth, wrapping up the 20th and final visit to the orbiting research complex for the current version of SpaceX’s supply ship before an upgraded Dragon starts launching later this year. Release from the space station’s robotic arm occurred at 9:06 a.m. EDT (1306 GMT), followed by splashdown in the Pacific Ocean at 2:50 p.m. EDT (1850 GMT).
