An antenna-covered communications spacecraft that will bring more bandwidth and capacity to the U.S. military’s global information grid than any single satellite ever before was successfully launched Wednesday atop a Delta 4 rocket.

A team of United Launch Alliance and NASA engineers worked through Delta 2 launch day fueling procedures during a simulated countdown Wednesday for what should be the second-to-last time before the venerable rocket’s final liftoff next month from California’s Central Coast.
