*not drawn to scale Mission Description For the NG-16 mission, the Cygnus Ellison Onizuka will be launched into orbit and Space Development Agency (SDA) spacecraft will deliver approximately using an Antares 230+ rocket from Virginia experimental mission called the Prototype 3,700 kg. (8,200 lb.) of cargo to the space Space’s Mid-Atlantic Regional Spaceport Infrared Payload (PIRPL). Upon arrival at the station. Cygnus is comprised of two (MARS) Pad 0A on Wallops Island, Virginia. ISS, PIRPL will begin collecting infrared data primary components, the Pressurized Northrop Grumman will once again load which will define possible by expanding Cargo Module and the Service Module. critical cargo into Cygnus 24 hours before detection capabilities. The data collected In keeping with company tradition, each the scheduled launch. will aid the development of algorithms for spacecraft is named after an important the next generation of tracking satellites.. figure in the aerospace industry. Northrop Upon arrival at the International Space Once its mission has been completed, Grumman is honored to name the NG-16 Station, the cargo will be unloaded from Cygnus will perform a safe, destructive Cygnus spacecraft after Ellison Onizuka, Cygnus. Riding as a payload on the S.S. reentry into Earth’s atmosphere over the the first Asian American astronaut. The S.S. Ellison Onizuka is a Northrop Grumman Pacific Ocean.
