Video: Liftoff of Atlas 5 with X-37B on program’s fourth flight

Tucked inside a shipping crate aboard an Air Force C-5 transport aircraft, the Navy’s next mobile communications satellite has flown from California to Florida in preparation for liftoff this summer.

The final year of launches in the current breed of Global Positioning System navigation satellites kicks off Wednesday afternoon aboard a Delta 4 rocket from Cape Canaveral.

Firing through a veil of fog blanketing California’s Central Coast, a Falcon 9 launcher climbed into orbit Wednesday with 10 more satellites for Iridium’s voice and data relay constellation, pushing the upgraded network closer to completion as SpaceX accomplished another landing of the rocket’s first stage booster.
