SpaceX launched a Falcon 9 rocket Friday at 5:39 p.m. EDT (2139 GMT). The commercial booster is hauling up the Thaicom 8 television broadcasting satellite from Cape Canaveral. The rocket’s first stage successfully landed on SpaceX’s recovery platform in the Atlantic Ocean.

A Russian Soyuz booster and an automated Progress resupply ship reached their launch pad Friday at the Baikonur Cosmodrome in Kazakhstan, two days before firing into orbit test out a new expedited rendezvous sequence that will culminate in the Progress spacecraft’s docking with the International Space Station just three-and-a-half hours after launch.
