Video: Liftoff of Atlas 5 on space station cargo mission

The 330-foot-tall mobile service tower is rolled away from the United Launch Alliance Delta 4 rocket at Cape Canaveral’s pad 37B in the hours before the scheduled liftoff. The 9-million-pound gantry was retracted the length of a football field in preparation for launch of the Air Force’s WGS 9 communications satellite into Earth orbit.

Loaded onto a SpaceX recovery ship, the Crew Dragon capsule that performed a successful in-flight abort test Sunday over Florida’s Space Coast pulled into Port Canaveral hours later after being retrieved from the Atlantic Ocean.

United Launch Alliance teams mounted a top secret payload for the National Reconnaissance Office on top of an Atlas 5 rocket Monday at Cape Canaveral in preparation for a liftoff scheduled just after sunset Nov. 3.
