One of its main goals is the launch of Artemis I, an unmanned lunar mission designed to show that the Orion spacecraft and the Space Launch System missile will be able to send humans to our lunar neighbor. But first, NASA plans to make some noise with this month’s fiery SLS test.
NASA is nearing the end of its Green Run test series that puts the base stage – which the agency describes as „the backbone of an SLS missile“ – through its paces before it actually takes off from this rock at some point in the future.
The eighth and final part of the test series could happen around January 17th when NASA starts an exciting hot fire.
„The upcoming hot fire test will fire all four RS-25 engines simultaneously for up to eight minutes to simulate base stage performance during launch.“ NASA said in a statement Tuesday.
While developing it, it is still at the center of NASA’s ambitious plans to return humans to the moon by 2024 through the Artemis program. Report from last year Based on program costs, SLS setbacks, and scheduling impacts from the coronavirus pandemic.

Test fires are so much fun, as we saw last year when it wasAnd sand turned into glass.
The SLS Green Run test will take place at Stennis Space Center in Mississippi, and it comes after NASA worked to solve an unexpected problem in a previous test, a wet dress rehearsal that marks the first time that cryogenic or supercooled liquid fuels have been used. Two large primary-stage SLS tanks to drain from. „
The rehearsal stopped a little early, but NASA traced the problem down to a timing issue that was later corrected that shouldn’t affect the hot fire. If all goes well, NASA will remain on track for a potential late 2021 launch of Artemis I.
Each successful test brings the moon a little closer within human reach.
