Bound for an orbital rendezvous with the International Space Station on Wednesday, a commercial Cygnus freighter was successfully launched by an Atlas 5 rocket Sunday to restart American cargo deliveries to the research outpost.

A replay of the United Launch Alliance Atlas 5 rocket launching the classified NROL-55 payload for the National Reconnaissance Office from Vandenberg Air Force Base, California.

Gusty winds associated with a subtropical low pressure system prevented United Launch Alliance from sending an Atlas 5 rocket into orbit Saturday from Cape Canaveral with the U.S. Air Force’s clandestine X-37B spaceplane. ULA plans to try again Sunday, and a SpaceX Falcon 9 rocket launch from a nearby pad has been delayed to Tuesday.
