The 330-foot tall mobile service tower is rolled away from the United Launch Alliance Delta 4 rocket at Cape Canaveral’s pad 37B in the hours before the scheduled liftoff on Aug. 19. The 9-million-pound gantry was retracted the length of a football field in preparation for launch of the GSSAP payload into Earth orbit for the Air Force.
