Officials have accepted a Friday launch date for a commercial cargo ship to the International Space Station after Range availability scuttled notions of moving up the Atlas 5 flight by a day.

The mission, dubbed NG-21, was the second out of three planned launches of a Cygnus spacecraft onboard a Falcon 9 rocket. Liftoff happened on Sunday, Aug. 4, at 11:02 a.m. EDT (1502 UTC).

Based upon an on-time launch Thursday, this is the timeline for Cygnus from liftoff through capture by the space station’s robotic arm.
