Watch a time-lapse video of the Atlas 5 rocket’s rollout at Cape Canaveral on Feb. 28, on the eve of liftoff with the GOES-S weather satellite.

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.

SpaceX called off the planned launch of a Falcon 9 rocket Friday at Cape Canaveral, halting the countdown less than a minute before liftoff to allow time to perform additional ground system checkouts before the mission’s next launch opportunity no earlier than Sunday.
