Video: Weather causes Atlas 5 countdown hold

A United Launch Alliance Atlas 5 rocket topped by the Air Force’s X-37B miniature space shuttle blasted off from Cape Canaveral’s Complex 41 today to deliver the spaceplane into orbit.

Members of the news media — reporters and photographers — witnessed the United Launch Alliance Delta 4-Heavy rocket lifted off from the ITL Causeway on Cape Canaveral Air Force Station, about 1.7 miles from the pad.

United Launch Alliance has granted “flight clearance” for its workhorse Atlas 5 rocket to resume satellite deployments after linking an errant valve with the fuel usage crunch on its most recent mission and tweaking subsequent vehicles.
