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).

Firefly Aerospace’s Blue Ghost lander will deploy first and is designated as the primary payload and ispace’s Resilience lander will follow about 30 minutes after. Liftoff from pad 39A happened at 1:11 a.m. EST (0611 UTC).
