Antares 230 successfully returns with launch of OA-5 Cygnus

Orbital ATK’s Antares rocket returned to flight in a new configuration on Monday, two years after its previous mission ended in an explosion seconds after liftoff. Monday’s launch took place from the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia – at the end of a five-minute window at 19:45 EDT (23:45 UTC). The launch was the sixth flight of the Antares, but it was first to use the Antares-230 configuration, differing from previous rockets by the use of RD-181 first stage engines in place of the AJ-26-62 motors used in the 110, 120 and 130 configurations.
