Orbital Sciences’ Cygnus cargo spacecraft was installed to the Harmony module of the International Space Station with no issues. The Expedition 40 crew will begin unloading approximately 3,300 pounds of science investigations, food and supplies when the hatch between the newly arrived spacecraft and the Harmony module of the space station is opened Thursday. The spacecraft is scheduled to spend about a month attached to the station.
Orbital’s Cygnus was launched on the company’s Antares rocket at 12:52 p.m. EDT, Sunday, July 13, from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia. Cygnus will remain attached to Harmony until a planned unberthing August 15. After it departs the orbital laboratory, carrying about 3,000 pounds of trash with it, the spacecraft will conduct additional tests for future missions to the space station before a destructive re-entry in Earth’s atmosphere.
