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

A day after a rare last-minute abort by its Soyuz launcher, a sharp-eyed civilian-operated Russian Earth observation satellite blasted off from the Baikonur Cosmodrome on Sunday on a five-year mission, giving Russia a fleet of three advanced digital imaging spacecraft in orbit.

SpaceX launched 60 more Starlink satellites from the Kennedy Space Center at 7:29 a.m. EDT (1129 GMT) Tuesday aboard a Falcon 9 rocket. Meanwhile, the launch of another SpaceX rocket a few miles away with a GPS satellite has been postponed indefinitely after a countdown abort moments before liftoff Friday night.

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.
