See NASA’s Massive SLS Moon Missile Attacks (and Shutdown Early)



The latest SLS Green Run tests take place at NASA’s Stennis Space Center in Mississippi.

One of the NASA’s Top Goals for 2021 is the launch of Artemis I, an unmanned lunar mission intended to demonstrate that the Orion spacecraft and the Space Launch System rocket can safely send humans to our lunar neighbor. But first, NASA made some noise with a fiery SLS test on Saturday.

NASA was nearing the end of the Green Run test series that will put the core stage through its paces before actually launching off this rock sometime in the future. The agency describes the core phase as “the backbone of the SLS missile”

The eighth part of the test series was scheduled for Saturday, when NASA initiated an exciting hot fire. NASA TV provided live coverage showing the four huge engines. You can revisit the action below.

The test was designed to simulate starting conditions for the RS-25 engines and was to take up to eight minutes. NASA ended the test prematurely, just over a minute after the start of the main event. The engines seemed to stall safely.

“Teams are reviewing the data on the engine shutdown early,” NASA tweeted shortly after the test.

Test fires are a lot of fun, as we saw one last year SLS booster lit up the Utah desert and turned sand into glass. Despite the brevity of the core test, it was quite a sight to see the swirling output from the raging engines.

SLS has seen delays during development, but it is still at the heart of NASA’s ambitious plans to return humans to the moon through the Artemis program by 2024. A report from last year calls into question that date based on the cost of the program, the SLS setbacks and the planning effects of the corona pandemic.

The SLS Green Run test took place at the Stennis Space Center in Mississippi and came after NASA fixed an unexpected problem with a previous test, a wet dress rehearsal that “ marked the first time cryogenic, or super cold, liquid propellant was fully charged. in and out of the two immense tanks of the SLS nuclear stage. “

The wet dress rehearsal was also cut short early, but NASA tracked down the issue to a timing issue that was later corrected. After analyzing what happened to this latest test, NASA hopes it’s still on track for a possible launch of Artemis I in late 2021.

Each successful test puts the moon a little closer to human hands.
