After a brief delay to chase away a boat from offshore waters, Japan’s H-2A rocket launched at 0650 GMT (1:50 a.m. EST) with the Telstar 12 Vantage telecom satellite. The launch from marks the first flight of an H-2A rocket with an upgraded upper stage, and the launcher’s first dedicated commercial mission.

Three fresh crew members lifted off at 1541 GMT (11:41 a.m. EDT) Friday on a six-hour trip to the International Space Station, riding a Soyuz spaceship from the Baikonur Cosmodrome in Kazakhstan. The trio hails from Russia, the United States and Italy and boosted the station’s crew back to a full complement of six. Docking occurred at 2154 GMT (5:54 p.m. EDT).

A team of United Launch Alliance and NASA engineers worked through Delta 2 launch day fueling procedures during a simulated countdown Wednesday for what should be the second-to-last time before the venerable rocket’s final liftoff next month from California’s Central Coast.
