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

Rocket Lab launched a radar imaging satellite Tuesday for the Japanese company Synspective. The small Earth observation payload lifted off from New Zealand at 5:09 a.m. EST (1009 GMT) aboard an Electron rocket. Rocket Lab did not attempt to recover the Electron’s first stage on this mission.

Check out photos of Wednesday’s launch of a Russian Rockot booster, derived from a decommissioned Soviet-era nuclear missile, with Europe’s Sentinel 3B Earth observation satellite.

A European Ariane 5 rocket delivered two commercial communications satellites to orbit Thursday after Arianespace’s ground team lost telemetry from the launcher during its climb into orbit, raising concerns that the mission might have failed. The SES 14 and Al Yah 3 satellites are confirmed in orbit and healthy, but the parameters of their orbits are unknown. Both were heading toward 22,000-mile-high geostationary perches over the equator.
