NASA successfully completes full hot fire of Huntsville-managed SLS core stage, taking Americans closer to the moon and Mars

NASA on Thursday successfully conducted a full hot fire of the core stage for the agency’s Space Launch System (SLS) rocket that is scheduled to launch the Artemis I mission to the moon, hopefully later this year.

The hot fire was the final test of the eight-part, 12-month Green Run series, conducted at Mississippi’s Stennis Space Center. This was the second hot fire attempt; the first go-around, which showed that the “core stage and the RS-25 engines performed perfectly,” ended prematurely out of an over-abundance of caution in testing parameters.

SLS is the world’s most powerful ever rocket that will power America’s next-generation moon missions and subsequent crewed missions to Mars. Alabama’s aerospace industry has led the effort to build the SLS, which stands 212 feet high and 27.6 feet in diameter.
