GenCorp (NYSE: GY) company Aerojet Rocketdyne said that its dual AJ26 main engine system successfully boosted Orbital Sciences Corp.´s (NYSE: ORB) Antares rocket and Cygnus spacecraft on the first commercial resupply services mission carrying the Cygnus cargo logistics spacecraft to the International Space Station (ISS).
Liftoff occurred at 1: 07 p.m. EST from NASA´s Wallops Flight Facility in Virginia. Following in-orbit activation shortly after launch, the Cygnus spacecraft will use 32 Aerojet Rocketdyne MR-106M 7 lbf monopropellant hydrazine thrusters to perform required in-orbit maneuvers. Berthing with the ISS is scheduled for approximately 6 a.m. (EST) on Sunday, Jan. 12.
The AJ26 is a commercial derivative of the NK-33 engine that was first developed by the Kuznetsov Design Bureau of Samara, Russia, to power the Russian N-1 rocket on a lunar mission in the early 1970s. As an oxidizer-rich, staged-combustion, oxygen kerosene engine, it achieves very high performance in a lightweight, compact package.
The Orbital-1 commercial resupply services mission is the first of eight missions covered under the CRS contract. Aerojet Rocketdyne´s small monopropellant hydrazine thrusters aboard the Cygnus enable the spacecraft to move in any direction required for the mission.
