Video: Change of command aboard International Space Station

A Soyuz rocket is standing on the launch pad in Kazakhstan used on Yuri Gagarin’s historic first human spaceflight in 1961, ready to send three people toward the International Space Station.

SpaceX’s launch of a cluster of communications satellites for Orbcomm, set for as soon as next weekend, holds the headlines, but the company’s Falcon 9 rocket could fly at least four times in the next two months, assuming smooth launch campaigns and no glitches.

A Falcon 9 rocket is being readied for a space station resupply mission at Kennedy Space Center’s launch pad 39A . The rocket is scheduled to launch at 10:01 a.m. EST (1501 GMT) on Saturday, weather permitting. Watch live coverage.
