Time lapse: Watch the Falcon Heavy placed on pad 39A

SpaceX was looking to rebound from a week of scuttled launches with a Falcon 9 launch from California but the Starlink 7-9 mission was delayed to Dec. 28 for unspecified reasons.

An 11-hour practice countdown was completed Friday at Cape Canaveral’s launch complex 41 for the planned launch of an Atlas 5 rocket and Boeing’s Starliner capsule later this month. The rocket was loaded with super-cold liquid oxygen and liquid hydrogen in a full dress rehearsal for launch day.

A SpaceX Falcon 9 rocket launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station at 10:17 p.m. EDT (0217 UTC on Oct. 22) carrying 23 Starlink satellites.
