Video: Atlas 5 GPS 2F-8 Launch Highlights

A replay of the United Launch Alliance Atlas 5 rocket launching the Orbital ATK’s commercial Cygnus cargo freighter to the International Space Station from Cape Canaveral, Florida.

The United Launch Alliance Atlas 5 rocket stands atop Space Launch Complex 3-East at Vandenberg Air Force Base in California on the eve of Wednesday’s NROL-79 satellite-deployment mission for the National Reconnaissance Office.

United Launch Alliance’s first Vulcan rocket was filled with methane and liquid oxygen propellants at Cape Canaveral last week for a tanking test, but managers decided to move the rocket back inside a hangar for a few adjustments before proceeding with an engine test-firing.
