NASA test fires former shuttle engine for 420 seconds1 min read

NASA put a former shuttle engine through its paces Thursday in a test tied to the development of the Space Launch System.

The RS-25 engine, formerly used on the space shuttle, fired for 420 seconds during a test at the Stennis Space Center, running at between 80 and 111 percent of its rated thrust.

NASA is repurposing the shuttle-era engines for use on the core stage of the SLS, which will use four RS-25 engines on each launch. []
