Photos: Atlas 5 rocket aims for International Space Station

Russia’s space agency says a Kazakh cosmonaut will fly to the International Space Station on 10-day mission in September, replacing British singer Sarah Brightman, who backed out of the mission in May.

The United Launch Alliance Delta 4 rocket sits peacefully inside its mobile service gantry on Tuesday afternoon, one day before its scheduled launch of the GPS 2F-9 navigation satellite.
