GenCorp Aerojet was awarded a $485,000 contract to design and test a high performance/high technology rocket injector for use in a Martian-simulated environment by the California Institute of Technology's Jet Propulsion Laboratory (JPL) on May 27.

The rocket injector, using MON-25/Monomethylhydrazine

propellants, will be used for the Mars Ascent Propulsion

System (MAPS) Attitude Control Thruster Initial Phase

Development Program. This program is necessary to develop

enabling propulsion technologies required by the Mars Sample

Return Vehicle, a major component in NASA's Mars Exploration

Program.

"This is an exciting win for Aerojet," said Bob Harris,

Aerojet vice president of Strategic and Space Propulsion.

"Interplanetary exploration technology exceeds the

capabilities of current state-of-the-art propulsion systems

and Aerojet is proud to play a part in developing innovative

propulsion solutions."

The Aerojet MAPS program will be accomplished at the

Sacramento facility over a seven-month period beginning late

May. The initial effort of the program will focus on injector

design characteristics required to produce high performance

and stable combustion using low temperature propellants which

have freezing points below -50 degrees C, similar to the

Martian environment. Subsequent phases will further develop

and test new-technology lightweight components intended for

the final flight version of the engine.

In addition to the Mars sample return mission, this task has

applicability to a wide variety of other missions as well

since low freezing-point propellants are also likely to be of

use to any outer planet missions.
