Video: Delta 4 lifts off

After being put back in position around the Delta 4-Heavy rocket after Thursday’s weather scrub, the 330-foot tall mobile service tower is retracted again at Cape Canaveral’s pad 37B for launch that will place the NROL-37 payload into Earth orbit.

A European Vega launcher failed Wednesday night around two minutes after liftoff from French Guiana and fell into the Atlantic Ocean, destroying an Airbus-built surveillance satellite for the United Arab Emirates.

Canada’s three new Radarsat Earth observation satellites were encapsulated inside the payload fairing of SpaceX’s Falcon 9 rocket ahead of their liftoff from Vandenberg Air Force Base in California.
