Orbital Sciences Corp. of Dulles, Va., mated the Cygnus Service Module to the Pressurized Cargo Module Friday, April 4, in Bldg. H-100, payload processing facility, at NASA’s Wallops Flight Facility, Va. The Service Module for the Orb-2 mission, which will deliver approximately 1,650 kg of supplies to the International Space Station (ISS), arrived at NASA’s Wallops Flight Facility March 31, 2014. The Pressurized Cargo Module, which arrived at Wallops in late January, was loaded with initial cargo the last weekend of March. The fully-fueled Cygnus spacecraft will be integrated with the Antares rocket in late April in anticipation of launch, scheduled for May 6 at 3:44 p.m. EDT, from Mid-Atlantic Regional Spaceport Pad 0A at NASA Wallops.
