Tomorrow NASA will test the most powerful rocket engines in the world at Stennis Space Center. NASA plans to send the first woman and next man to the moon in 2024 as part of the Artemis Program. Stennis has been preparing its B2 test stand to test NASA’s Space Launch System, SLS, which will be the world’s largest and most powerful rocket. Saturday, NASA will test the SLS core stage, which was partially built in New Orleans East at NASA Michoud Assembly Facility. All four RS-25 engines will fire simultaneously, just as during an actual launch. They will generate 1.6 million pounds of thrust, which will possibly be heard as far as 60 miles away.
