Live coverage: 400th Proton rocket takes off with Russian satellite

The Russian Soyuz MS-13 spacecraft departed the International Space Station and landed in Kazakhstan Thursday, bringing home outgoing space station commander Luca Parmitano, Soyuz pilot Alexander Skvortsov, and NASA astronaut Christina Koch, who concluded a 328-day mission, the longest-ever spaceflight by a woman. The Soyuz undocked from the station at 0550 GMT (12:50 a.m. EST) Thursday, then landed on the Kazakh steppe at 0912 GMT (4:12 a.m. EST).

Europe’s Sentinel 3A satellite, designed for real-time surveys of the world’s oceans, ice sheets, lakes and rivers, is attached to a decommissioned Russian nuclear missile for launch Tuesday. These photos show the spacecraft’s final prelaunch preparations.
