Photos: Tuesday’s Atlas 5 rollout

A United Launch Delta 4 rocket lifted off Friday from the SLC-6 launch pad at Vandenberg Air Force Base in California, powering into orbit from a historic seaside complex originally developed for crewed missions.

The U.S. Air Force’s reusable Boeing-built X-37B spaceplane returned to Earth early Sunday with a touchdown at NASA’s Shuttle Landing Facility runway at the Kennedy Space Center in Florida, a few miles away from where it launched 780 days ago atop a SpaceX Falcon 9 rocket.

Constructing the launch pad infrastructure for astronauts to board Boeing’s Starliner crew capsules atop United Launch Alliance Atlas 5 rockets, workers delivered the Crew Access Arm with its White Room to Cape Canaveral’s Complex 41 on Thursday, Aug. 11.
