Photos: Gantry retracted from Delta 4-Heavy

The 330-foot tall mobile service tower is rolled away from the United Launch Alliance Delta 4-Heavy rocket at Cape Canaveral’s pad 37B just after sunrise on June 9. The 9-million-pound gantry was retracted the length of a football field in preparation for launch of the NROL-37 payload into Earth orbit.
