Alabama Built SLS Engines Tested

"This flight support booster test is the first motor firing NASA and Northrop Grumman have completed since qualifying the booster design for the Space Launch System rocket," Tiller said in a news release. "Full-scale booster tests are rare, so NASA tries to test multiple objectives at one time so we are highly confident that any changes we make to the boosters will still enable them to perform as expected on launch day."
The Space Launch System is powered by four RS-25 engines and two boosters, a combination capable of generating 8 million pounds of thrust. The two five-segment rocket boosters will be responsible for 75 percent of thrust during the first few minutes of the Space Launch System's ascent."
