Aerojet Delivers Final Orion EFT-1 Crew Module Reaction Control System Pod Assembly

Aerojet Delivers Final Orion EFT-1 Crew Module Reaction Control System Pod

SACRAMENTO, Calif., May 8, 2013 (GLOBE NEWSWIRE) -- Aerojet, a GenCorp
(NYSE:GY) company, announced today that the final Crew Module Reaction Control
System (CM RCS) pod assembly for NASA's Orion spacecraft's Exploration Flight
Test-1 (EFT-1) has arrived at the Operations and Checkout Building at NASA's
Kennedy Space Center (KSC) in Florida.

Aerojet's CM RCS pods will provide the full complement of primary and
redundant control required for critical maneuvers upon a high-speed re-entry
into the Earth's atmosphere. This specific hardware will be integrated into
the Orion spacecraft to support NASA's EFT-1 mission, currently slated for

"We take our 100 percent mission success record seriously," said Julie Van
Kleeck, Aerojet's vice president of Space and Launch Systems. "We put our
heart into our products and the integration work at KSC will close more than
three years of design and development activities in support of EFT-1."

The two assemblies delivered now join six others already at KSC, including two
pitch-up pods with a single rocket engine; two pitch-down pods, each with a
single rocket engine; two right and left roll pods, each with two rocket
engines; and two right and left yaw pods, each with a single rocket engine.

Beginning in June, the pods will undergo proof pressure and leak testing,
valve leak testing and rocket engine functional testing at NASA. Aerojet will
support processing activities that involve the rocket engine pods with
procedure reviews and onsite engineering and assembly support during
installation and testing on the crew module.

The CM RCS pod assemblies were designed by a multi-disciplinary team that
utilized expertise across several Aerojet sites nationwide. The propulsion
system utilizes Aerojet MR-104G 160 lbf monopropellant engines that are
configured into four major pod design variants. The pod development work
culminated with the final fabrication and assembly of the complete EFT-1
shipset at Aerojet's facility in Redmond, Wash. Aerojet performed the CM RCS
work under contract with NASA's Orion prime contractor, Lockheed Martin
Corporation (NYSE:LMT).

The Orion Multi-Purpose Crew Vehicle, currently in development, is an advanced
spacecraft design utilizing state-of-the-art technology that will allow humans
to travel beyond low-Earth orbit on future missions to destinations such as
asteroids, Lagrange Points, the moon and, someday, Mars. The LAS design, using
an Aerojet jettison motor, is a key element to NASA's continuing efforts to
improve astronaut safety as the agency develops this next generation of
