NASA Updates on Engine Test Project for Space Launch System Rocket

July 22, 2014

NASA said engineers have taken a step in preparing to test parts of NASA's Space Launch System (SLS) rocket that will send humans to new destinations in the solar system.

According to a July 17 release from the company, the engineers installed on Thursday an RS-25 engine on the A-1 Test Stand at the agency's Stennis Space Center near Bay St. Louis, Mississippi.

NASA said the Stennis team will perform developmental and flight certification testing of the RS-25 engine, a modified version of the space shuttle main engine that powered missions into space from 1981 to 2011.

The SLS's core stage will be powered by a configuration of four RS-25 engines, like the one recently installed on the A-1 stand.

"This test series is a major milestone because it will be our first opportunity to operate the engine with a new controller and to test propellant inlet conditions for SLS that are different than the space shuttle," said Steve Wofford, SLS Liquid Engines Element manager. "This testing will confirm the RS-25 will be successful at powering SLS."

Early tests on the engine will collect data on the performance of its new engine controller and other modifications. The controller regulates valves that direct the flow of propellant to the engine.

"Installation of RS-25 engine No. 0525 signals the launch of another major rocket engine test project for human space exploration on the A-1 Test Stand," said Gary Benton, RS-25 rocket engine test project manager at Stennis.

NASA noted that the SLS is designed to carry astronauts in NASA's Orion spacecraft deeper into space than ever before, to destinations including an asteroid and Mars.

The SLS Program is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama.
