Video: X-37B payload mated to Atlas 5

As viewed from the ITL Causeway at the Cape Canaveral Air Force Station, the United Launch Alliance Atlas 5 rocket departs for space with the EchoStar 19 satellite to delivery Internet connectivity across the U.S.

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 on launch day.

This collection of photographs shows the National Reconnaissance Office’s classified NROL-45 payload, already encapsulated in the Delta 4 nose cone, being moved from the payload processing facility at Space Launch Complex 6 and lifted atop the United Launch Alliance rocket for flight from Vandenberg.
