Photos: Delta 4-Heavy launch as seen from press site

This is video footage documenting stacking activities for the two-stage United Launch Alliance Atlas 5 rocket, standing 194 feet tall, to boost the commercial Orbital ATK Cygnus cargo freighter to the International Space Station. Activities occurred at Cape Canaveral’s Vertical Integration Facility.

A United Launch Alliance Atlas 5 rocket took off from Cape Canaveral on Aug. 8 with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, the second launch from Florida’s Coast in a span of less than 35 hours.

The static fire test was conducted by Northrop Grumman, the manufacturer of the GEM 63XL solid rocket booster that can be used to help power United Launch Alliance’s Vulcan rockets. An in-flight anomaly was observed on one of those back in mid-February.
