Green Run test completed

STENNIS SPACE CENTER, Miss - NASA today tested the core stage of the Space Launch System, firing all four RS-25 engines in a test that was closed to the public because of COVID-19 concerns. But the test that began about 4:20 CST was shown live on NASA television. The firing ended after just over a minute rather than going the full eight minutes. The next step could be putting the core stage on the Pegasus barge for transport to Kennedy Space Center in Florida unless a second test is done. Area residents were told a few days ago to expect elevated decibel levels for today's hot fire test. The engines produced a combined 1.6 million pounds of thrust, producing a noise about 10-20 decibels higher than during a normal single engine test at the site. (Source: GCAC, 01/16/21) Previous
