Video: Time-lapse of Atlas 5’s rollout for launch of GOES-S (members only)

Gusty winds associated with a subtropical low pressure system prevented United Launch Alliance from sending an Atlas 5 rocket into orbit Saturday from Cape Canaveral with the U.S. Air Force’s clandestine X-37B spaceplane. ULA plans to try again Sunday, and a SpaceX Falcon 9 rocket launch from a nearby pad has been delayed to Tuesday.

This gallery of U.S. Air Force photos show technicians, wearing protective SCAPE suits, initially check for hazardous hypergolic fuel vapors around the X-37B spaceplane on the Shuttle Landing Facility runway and the subsequent tow of the vehicle to its newly-renovated hangar at the Kennedy Space Center.

A new fixture on the Cape Canaveral skyline began rising Tuesday with the placement of the first of seven segments for a 200-foot-tall crew access tower at the Atlas 5 rocket’s seaside launch pad for astronauts boarding Boeing’s new commercial CST-100 Starliner spaceship.
