Aerojet, a GenCorp (NYSE:GY) company, has signed an Associate Contractor’s Agreement (ACA) with The Boeing Company (NYSE:BA) on the Ares I upper stage launch vehicle — NASA’s new space transportation system for the Orion crew vehicle. Participating companies within the ACA include: Aerojet, Boeing, Hamilton Sundstrand, Jacobs Engineering Group Inc., Moog Inc. and Teledyne Brown Engineering Inc. Aerojet’s Director of Space Propulsion & Systems, Carla Bossard, participated in the signing ceremony.

Aerojet has been under an existing contract with NASA’s Marshall Space Flight Center since May 2007 to develop the Roll Control System for Ares I. The two-stage rocket will carry NASA’s next generation Orion crew launch vehicle to Earth orbit. The roll control system is designed to ensure the Ares I stays on its designated trajectory throughout the first two minutes of flight. “We are looking forward to sharing in this collaboration as it will ensure best value of our roll control effort to the upper stage production project,” said Vice President of Space Programs, Julie Van Kleeck.
