See NASA’s massive SLS moon rocket fire (and stop early)


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

One of NASA’s main goal for 2021 To launch Artemis I, an unused moon mission is meant to show that Orion spacecraft and space launch system rockets can safely send humans to our lunar neighbor. But first, NASA made some noise on Saturday with a furious SLS test.

NASA was approaching the end of the Green Run Test Series which puts the reef through its phase into the main stage before launching it sometime in the future. The agency describes the main stage as “the backbone of the SLS rocket”.

The eighth of the test series was scheduled for Saturday, when NASA launched an exciting hot fire. NASA TV provided live coverage that showed four giant engines firing. You can see the below action again.

The test was designed to simulate launch conditions for the RS-25 engine and was meant to last for eight minutes. NASA finished the test a little over a minute before the main event. The engines appeared to stop safely.

“Teams are assessing early engine shutdown figures,” NASA tweeted soon after the test.

Test fires are great fun, as we saw last year when A. SLS Booster Burns Utah Desert And the sand turned into glass. Despite the brevity of the core stage test, it was quite a sight to see the billing output of fiery engines.

SLS has seen delays During its development, but it is still at the center of ambitious plans to bring humans back to the moon through the Artemis program by 2024. A previous year report Calls that date in question By SLS setback and scheduling effects, depending on the cost of the program Coronavirus epidemic.

The SLS Green Run test took place at the Stennis Space Center in Mississippi, and it came after working through an unexpected issue with previous testing by NASA, a wet dress rehearsal that “first appeared as a cryogenic, or super cold, liquid propellant.” Was marked in. Loaded into, and drained from, two huge tanks of SLS core platform. “

Wetwear rehearsals also cut quickly, but NASA tracked the problem to a timing issue that was later corrected. After analyzing what happened with this latest test, NASA expects it to still be on track for a possible late 2021 launch of Artemis I.

Each successful test puts the moon slightly closer to the reach of human hands.
