STENNIS SPACE CENTER, Miss. -- Aerojet Rocketdyne successfully achieved full-power during a preburner test series at NASA's Stennis Space Center earlier this month. The test series verified key preburner injector design parameters for the company’s AR1 engine that is being designed to end use of Russian engines for national security space launches. This testing is a continuation of earlier preburner testing at NASA's Marshall Space Flight Center in Huntsville, Ala., and Aerojet Rocketdyne's Sacramento, Calif., location.
