Photos: Atlas 5 rocket aims for International Space Station

A heavy-duty crane towering over launch pad 39A at NASA’s Kennedy Space Center in recent weeks has removed several large sections of a disused structure once needed to install satellites and space station modules into space shuttle cargo bays.

The launch of the seventh Wideband Global SATCOM military communications satellite aboard a Delta 4 rocket booster occurred tonight at 8:07 p.m. EDT (0007 GMT) from Cape Canaveral.

Air Force meteorologists are expecting good weather to launch the Delta 4 rocket with a military communications satellite Wednesday evening from Cape Canaveral.
