Snapshots from Atlas 5 launch

United Launch Alliance has packed two days of rollout, countdown and launch activities into a two-minute video highlighting Friday night’s blastoff of an Atlas 5 rocket from Cape Canaveral with the U.S. Air Force’s SBIRS GEO Flight 4 missile-warning satellite.

A United Launch Alliance Atlas 5 rocket made its third trip to a Cape Canaveral launch pad Thursday, rolling into position for liftoff Friday afternoon with a classified payload for the U.S. government’s spy satellite agency.

NASA’s Perseverance rover has been closed up inside its protective aeroshell, the structure that will protect the spacecraft when it plunges into the Martian atmosphere, in preparation for launch no earlier than July 20 from Cape Canaveral.
