Testing the RS-25 Engine

An impressive amount of power developed as the RS-25 engine is hot-fired on 19 October. This engine has a great history of reliability in the NASA shuttle program and will power the new Space Launch System.

In October of 2018 four of these engines will power the first flight test of SLS with Orion which will carry an uncrewed Orion spacecraft beyond the moon, deeper than any human-rated spacecraft has gone, to test the performance of the integrated system.

This test took place at NASA’s Stennis Space Center in Mississippi
