A commercial Cygnus resupply craft that received a new corporate owner while berthed at the International Space Station — thanks to Northrop Grumman’s acquisition of Orbital ATK in June — departed the research complex Sunday. The supply ship was released by Canadarm 2 on the space station at 8:37 a.m. EDT (1237 GMT).

A Northrop Grumman Cygnus supply ship arrived at the International Space Station on Monday with more than 8,000 pounds of cargo, including new astronaut sleeping quarters, parts for the station’s toilet, and numerous biomedical and technology experiments.

A veteran Russian cosmonaut and two spaceflight rookies rocketed into orbit from a Kazakh launch base Wednesday on the first flight of a new-generation Soyuz capsule, kicking off a two-day pursuit of the International Space Station.
