Video: Liftoff of Delta 4 with WGS 7

Egypt’s first military communications satellite and a powerhouse spacecraft to beam Internet signals to airline passengers and maritime vessels across Europe and the Middle East rocketed into orbit Tuesday on the 250th flight of an Ariane launcher. 

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a pursuit of the International Space Station.

Ground crews at Vandenberg Air Force Base in California retracted a mobile gantry away from the Delta 2 rocket Monday afternoon, revealing the 128-foot-tall (39-meter) booster on its launch pad awaiting liftoff with a new polar-orbiting weather observatory.
