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

A Proton booster rocketed away from the Baikonur Cosmodrome in Kazaskhtan Wednesday with a Eutelsat television broadcasting craft and the satellite industry’s first commercial in-space servicing vehicle. The successful launch marked the first commercial Proton mission under the auspices of International Launch Services in more than two years.

Seven small satellites from Canon Electronics, Planet and In-Space Missions launched from New Zealand on Rocket Lab’s Electron rocket Saturday at 5:19:36 p.m. EDT (2119:36 GMT), but the payloads and launch vehicle were lost after a problem during the second stage burn.

Europe’s ExoMars orbiter was enclosed inside the nose cone of its Proton rocket Wednesday ahead of its March 14 launch toward the red planet.
