Live coverage: Atlas 5 countdown and launch journal

This collection of photographs shows the Air Force’s Global Positioning System 2F-12 navigation satellite being encapsulated in the United Launch Alliance Atlas 5 nose cone and hoisted atop the rocket for flight on Friday morning.

Launching the U.S. Navy’s fifth MUOS mobile communications satellite, a United Launch Alliance Atlas 5 rocket thundered away from Cape Canaveral today.

NASA says initial checks show no damage to the Atlas 5 rocket or the agency’s asteroid-bound OSIRIS-REx spacecraft that stood within the Vertical Integration Facility just a mile away from the SpaceX explosion Thursday.
