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).

An Ariane 5 rocket has blasted off from a tropical launch pad in French Guiana on nearly 3 million pounds of thrust, hoisting two U.S.-built communications satellites to orbit for commercial owners in Brazil and Japan.
