[b]Northrop Grumman Set to Launch Cargo Resupply Mission and Perform Reboost Service for International Space Station[/b] [i]17th Cygnus, named in honor of astronaut Piers Sellers, will deliver critical supplies to astronauts[/i] Northrop Grumman Corporation is set to launch the company's 17th resupply mission (NG-17) to the International Space Station under NASA's Commercial Resupply Service-2 (CRS-2) contract. In addition to delivering 8,300 pounds of critical cargo to astronauts living aboard the station, the company's Cygnus spacecraft will perform its first operational International Space Station reboost service. Antares is scheduled to launch Saturday, Feb. 19 at 12:40 p.m. EST from the Mid-Atlantic Regional Spaceport Pad 0A at NASA's Wallops Flight Facility on Wallops Island, Virginia. Cygnus will rendezvous with the station on Feb. 21, where it will remain attached to the station for three months while performing the reboost. "We are expanding the suite of value-added capabilities that we offer through our proven Cygnus program," said Steve Krein, vice president, civil and commercial space, Northrop Grumman. "The addition of reboost services to Cygnus' capabilities provides NASA with an even greater tool to advance space science and exploration, whether that's on the International Space Station, the moon or beyond." Reboosting is a critical part of altitude maintenance for the station. Earth's atmosphere causes a slight amount of drag, causing the station's altitude to lower slowly over time. Small, precise nudges are required to place it back into its proper orbit. Northrop Grumman will perform the adjustment service while Cygnus is berthed with the station.
