NASA engineers capped a year of Space Launch System testing with a final RS-25 rocket engine hot fire on Dec. 13 at Stennis Space Center near Bay St. Louis, Miss. The 470-second test on the A-1 Test Stand was a “green run” test of an RS-25 flight controller. It marked the eighth RS-25 test of the year and the sixth flight controller to be tested for use on NASA’s new Space Launch System (SLS) vehicle. The engine tested also included a large 3-D-printed part scheduled for use on future RS-25 flight engines.

The RS-25, made by Rocketdyne, was first used on the Space Shuttles (SSME) since 1981. This is a used engine!! NASA is reusing them for the new STS, as they are the most powerful H2-O2 engines ever made. The most powerful engine is history was the Rocketdyne F-1 used in all the Saturn V rockets, which burned kerosene and O2 to produce 1.5 million pounds of thrust. Jeff Bozos (Amazomns founder) is collecting the pieces to rebuild one.

If you visit the Kennedy Space Center and take a bus tour, one of the stops has a disabled but genuine RS-25 engine exhibit that you can see close up. It is 14 feet tall and 8 feet in diameter with a 418, 000 pound thrust. Search for "SSME" or RS-25.
