Video: Atlas 5 rocket launches space station cargo mission

The Centaur upper stage destined to send Boeing’s CST-100 Starliner crew capsule into orbit on its first unpiloted test flight next year has arrived at Cape Canaveral after a sea journey aboard United Launch Alliance’s Mariner transport ship.

A small spacecraft built for the Russian military lifted off Thursday on top of a modified Soyuz booster, beginning a mission to reportedly test a compact Earth-imaging platform that could be used on future spy satellites.

Astronauts Shane Kimbrough and Thomas Pesquet put on their self-contained spacesuits and headed outside the International Space Station on Friday for a six-and-a-half hour excursion to prepare for the relocation of a docking adapter, service the lab’s Dextre robot, and install a new computer relay box.
