A little over two weeks after it tested the massive RS-25 rocket engine at the Stennis Space Center, the National Aeronautics and Space Administration (NASA) conducted another test yesterday as it pushed the engine beyond its requirements. NASA ran a hot fire test of the redesigned RS-25 engine at the Fred Haise test stand at the Stennis Space Center in Florida. The test was longer than the earlier run, and according to NASA, its duration was also longer than required for flight during a Space Launch System (SLS) launch.

Today's test ran for six hundred seconds, while a typical SLS launch fires the engines up for 500 seconds. The SLS is the space agency's workhorse rocket for the Artemis mission, through which it aims to develop a sustained human presence on the Moon. It uses the RS-25 eninges on its core stage, and these were originally designed for the Space Shuttle and intended to be reused after flight.

However, since the SLS is a non-reusable rocket, NASA and the engine's manufacturer Aerjoet Rocketdyne are looking at methods to attune the engine to the SLS by streamlining production and reducing weight and costs. Accoridng to NASA, the engines currently being tested at Stennis are "manufactured with new processes and components," with the tests a series of certification runs that aim to evaluate the design to ensure there are no problems with either the engine or its components before Aerojet can start production.

Even though it has launched only one SLS mission so far, NASA has tested engines for the first four flights at Stennis. These tests are running concurrently with rocket
