Snapshots from Atlas 5 launch

SpaceX’s Crew Dragon “Resilience” spacecraft and Falcon 9 rocket — stretching 215 feet long — are ready for rollout to pad 39A at NASA’s Kennedy Space Center in preparation for the launch of four astronauts Saturday night to the International Space Station.

A United Launch Alliance Delta 4 rocket blasted off from Vandenberg Air Force Base in California at 3:40 a.m. local (6:40 a.m. EST; 1140 GMT) today to place a secret payload into space for the National Reconnaissance Office. Follow the mission in our live journal.

United Launch Alliance is pushing back its next Atlas 5 launch from Cape Canaveral until no earlier than Aug. 8, allowing time for engineers to ensure an unspecified anomaly during component testing at a supplier will have no impact on the Atlas 5’s mission to place a U.S. Air Force communications satellite into orbit.
