Jednak centralny stopień SLS przejdzie 8-minutowy test statyczny nazywany Green Run, najprawdopodobniej w 2020.

In an agency statement, Bridenstine announced that NASA will proceed with the “Green Run” test of the SLS, where its core stage performs an eight-minute static-fire test at the Stennis Space Center in Mississippi. NASA did not disclose when the test will take place, although it’s widely expected to be some time next year.
“The Green Run acceptance test gives NASA the confidence needed to know the new core stage will perform again and again as it is intended,” Lisa Bates, SLS deputy stages manager at NASA, said in that statement. (...)
Both members of Congress and outside advisors pushed back against that proposal, though. “There is no other test approach that will gather the critical full-scale integrated propulsion system operational data required to ensure safe operations,” Patricia Sanders, chair of the Aerospace Safety Advisory Panel, said of the Green Run test at an April 25 meeting of the committee. “I cannot emphasize more strongly that we advise NASA to retain this test.” (...)
