STENNIS SPACE CENTER, Miss - Area residents can expect elevated decibel levels as Stennis Space Center targets Saturday for the final hot fire test in the Green Run test series on NASA’s new Space Launch System core stage. The acoustic level is not expected to reach high enough to have any damaging effect. The test will involve firing four RS-25 engines to produce a combined 1.6 million pounds of thrust. The acoustic level produced is expected to be about 10-20 decibels higher than during a normal single engine test at the site. NASA is targeting a two-hour test window that opens at 4 p.m. CST Jan. 16, for the hot fire test of the SLS core stage. Due to COVID-19, the public will not be allowed to view the test.
