NASA prepares to launch massive SLS lunar rocket for final Green Run test

The latest SLS Green Run tests are being conducted at NASA’s Stenis Space Center in Mississippi.


NASA has big dreams for 2021, with one of its main targets for launching Artemis I, an unwrapped lunar mission designed to showcase its Orion spacecraft and the Space Space Launch System rocket can send people to our lunar neighbor. But first, NASA plans to make some noise with SLS fire testing this month.

NASA is nearing the end of the Green Run test series, which puts the main stage ̵

1; which the agency describes as the “backbone of the SLS rocket” – in its steps before launching this rock somewhere in the future.

The eighth and final part of the test series could happen immediately on Saturday, January 16, when NASA initiates an exciting hot fire. The agency originally planned to run the test on January 17, but moved the day up after conducting a readiness review.

“The upcoming hot fire test will simultaneously activate all four of the RS-25 engines on stage for up to eight minutes to simulate the performance of the main stage during launch,” NASA said in a statement on January 5.

SLS noticed delays during its development, but is still at the heart of NASA’s ambitious plans to bring humans back to the moon by 2024 through the Artemis program. Report from last year questions that date based on program costs, SLS failures, and the impact on coronavirus pandemic planning.

Test fires are a lot of fun, as we saw last year when SLS booster illuminates the Utah desert and turned the sand into glass.

The SLS Green Run test will take place at the Stennis Space Center in Mississippi and comes after NASA is working on an unexpected problem with a previous test, a wet dress rehearsal that “marks the first time a cryogenic or super cold liquid propellant has been fully charged and recharged. of the two huge tanks at the main stage of the SLS. “

The wet dress rehearsal was interrupted a little earlier, but NASA traced the problem to a time issue that was later corrected and should not affect the hot fire. If all goes well, then NASA will still be on track to launch Artemis I at the end of 2021.

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