DULLES, Va. - Northrop Grumman Corporation is set to launch the company’s 16th resupply mission (NG-16) to the International Space Station under NASA’s Commercial Resupply Services-2 (CRS-2) contract. For the NG-16 mission, the Cygnus spacecraft will launch aboard the company’s Antares rocket, carrying approximately 8,200 pounds of supplies, equipment and experiments for the astronauts aboard the station—the company’s largest resupply delivery to date.

Antares is set to launch Aug. 10 at 5:56 p.m. EDT from the Mid-Atlantic Regional Spaceport 0A at NASA’s Wallops Flight Facility in Virginia. Cygnus is scheduled to rendezvous with the Space Station on Aug. 12.

Each Cygnus spacecraft is named in honor of an individual who has made significant contributions to the U.S. space program and human spaceflight. For the NG-16 mission, Cygnus commemorates Ellison Onizuka, the first Asian American astronaut. After a long and successful career as a test pilot at the U.S. Air Force Test Pilot School, Onizuka was selected to become a NASA astronaut in 1978 and flew his first mission in 1985. In 1986, Onizuka and his crew tragically lost their lives during the launch of Space Shuttle Challenger.

The S.S. Ellison Onizuka will remain attached to the ISS for approximately three months before departing with up to 8,221 pounds (approximately 3,729 kilograms) of disposal cargo.

Riding as a payload on the Cygnus spacecraft is a Northrop Grumman, Space Development Agency (SDA) and Missile Defense Agency (MDA) experimental mission called the Prototype Infrared Payload (PIRPL). Upon arrival at the Space Station, PIRPL will begin collecting infrared data and expanding detection capabilities that will aid in the development of algorithms for the next generation of tracking satellites.
