Photos: Atlas 5 rolls out for launch

United Launch Alliance is set to retire part of its rocket family Thursday with the final flight of the Delta 4 rocket’s “single stick” configuration, a mission set for liftoff from Cape Canaveral carrying a new GPS navigation satellite into orbit for the U.S. Air Force.

Take a look back on the liftoff of Boeing’s Starliner spacecraft on its first orbital test flight Dec. 20 aboard a United Launch Alliance Atlas 5 rocket with these photos showing the capsule streaking into space at dawn.

A SpaceX Dragon capsule packed with more than 5,000 pounds of hardware, provisions and experiments launched July 25 from Cape Canaveral and arrived at the International Space Station two days later.
