Video: Pegasus and CYGNSS pre-launch news conference

More photos show the successful liftoff of the United Launch Alliance Atlas 5 rocket flight carrying the Cygnus commercial cargo spacecraft for Orbital ATK and the International Space Station.

Orbital ATK’s Antares rocket will deliver the commercial Cygnus supply ship to an orbit with an altitude between 117 miles (189 kilometers) and 184 miles (296 kilometers) within about nine minutes of liftoff Saturday from Virginia’s Eastern Shore.

An Orbital ATK Minotaur 4 rocket partially powered by modified motors from a Cold War-era nuclear missile lifted off early Saturday from Cape Canaveral with a small U.S. military satellite to help track other objects in space. The solid-fueled launcher took off at 2:04 a.m. EDT (0604 GMT) after a weather delay.
