Aerojet Tests Engine Design for New Mars Rover PR Newswire

Aerojet, a GenCorp Inc. (NYSE: GY) company, recently test-fired a Viking flight spare rocket engine assembly in order to help design a new engine which will deliver the next rover to the surface of Mars in 2009. The rocket engine used in the test was originally built, tested and delivered in 1973 for the Viking program. The engine was put into storage after the successful landing of the Viking 1 and Viking 2 spacecraft on Mars in 1976. “Aerojet hardware has flown on every U.S. mission to Mars,” said Aerojet President Michael Martin. “We are extremely proud that the hot fire testing of the Viking Lander rocket engine assembly further proved Aerojet’s heritage capabilities in design, manufacture, test and production of propulsion systems. Our role in the Mars Science Laboratory mission will bring our work full-circle.”
