NASA The second RS-25 single engine fire test was performed on April 6, 2018.SLS) Rocket on a future mission to the moon

The full-time fire for over eight minutes (500 seconds) was performed on the A-1 test stand at NASA’s Stennis Space Center near St. Louis Bay. It is part of a seven test series designed to provide valuable information for Aerojet Rocketdyne, the lead contractor for the SLS engine, as it began production of the new RS-25 engine for use after the first four SLS flights.

Four RS-25 engines propelled the SLS when launched, firing simultaneously to generate a combined £ 1.6 million thrust upon launch and £ 2 million of thrust during the RS-25 engine boarding for the first four SLS flights. It is an upgraded and tested Space Shuttle main engine.

During the test of the new series, operators will focus on evaluating new engine components and reducing engine operating risks. They will fire engines through a variety of operating conditions to demonstrate and validate engine capabilities and to provide information to improve production of new engines manufactured with cutting-edge and cost-effective technology.

The first test of the new series was performed on January 28, also for 500 seconds, the same time the engine had to fire during launch to power the SLS rocket into orbit. During the subsequent full-heat shutdown on April 6, the operator also powered the RS-25 engine using a NASA-designed vector control system for the first time since “Gimbaling” was installed. The engine must move on a tight circular axis for proper trajectory.

NASA is building the SLS as the most powerful rocket on Earth.The SLS will fly to the moon as part of NASA’s Artemis program, including this year’s Artemis I test flight, which will pave the way for future flights with astronauts. To explore the lunar surface and prepare for missions MarsRS-25 testing at Stennis was conducted by a team of NASA, Aerojet Rocketdyne and Syncom Space Services. Syncom Space Services is the primary contractor for Stennis facilities and operations.
