The Atlas 5 rocket emerges from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station. Liftoff is set for Thursday at 5:55 p.m. EST.

An Atlas 5 rocket successfully launched another Cygnus cargo freighter for Orbital ATK Tuesday night, fulfilling the booster’s role of reestablishing America’s resupply link to the International Space Station.

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.
