The first Cygnus commercial cargo spacecraft built by Orbital Sciences is seen here attached to the International Space Station's Harmony node. This week, the Cygnus cargo spacecraft that was launched from NASA’s Wallops Flight Facility on Sept.18, will complete its successful maiden cargo mission on Tuesday when it un-berths from the International Space Station and burns up harmlessly in Earth’s atmosphere during re-entry the following day. Orbital Sciences Corp. joins SpaceX as NASA’s second American commercial partner capable of successful resupply missions to the ISS.
