Live coverage: Cygnus supply ship departs space station

A Russian Proton rocket topped with a commercial U.S.-built communications satellite for AsiaSat is standing on a launch pad in Kazakhstan for liftoff Thursday.

A Russian Soyuz rocket rolled out to its launch pad in Kazakhstan on Monday, two days before its scheduled departure with three passengers on the way to the International Space Station.

The sixth and final satellite in the U.S. military’s most secure satellite communications fleet lifted off from Cape Canaveral Thursday aboard a United Launch Alliance Atlas 5 rocket, extending the network’s expected lifetime beyond 2030.
