499.6 seconds: NASA and Boeing Complete Hot Fire-2 for Space Launch System Core Stage

We fired up NASA Space Launch System Core Stage 1 during Green Run Test 8 - Hot Fire. Our teams conducted a successful full-duration 8 minute (499.6 seconds) hot fire of the Artemis I core stage in the iconic B-2 test stand at NASA’s Stennis Space Center. This is a display of all of the rocket’s power without the launch so we can ensure that it is ready for flight.

NASA and Boeing engineers will take back mountains of data and inspect the core stage to determine how it performed during the test. Video via NASA.

When the standard indoor humidifier just doesn't suffice.

I lived in Picayune when I was a kid when they were still testing the Saturn 5 engines. From 12 miles away (as the crow flies) it was still impressively loud. Later, I worked at Stennis when they were testing the Shuttle main engines. Impressive to hear and see.

W-O-W + W-H-O-A ! ! ! I AM AMAZED THAT THE WHOLE TEST FACILITY DOESN'T LIFT OFF THE GROUND WITH ALL THAT ENERGY BEING UNLEASHED ! ! !👍👍👍👍👍👍👍

I would love to watch this in person. I was fortunate enough in my life to have witnessed three Shuttle main engine tests at Stennis. Nothing like watching it in person, the video as good as it is, just doesn't do it justice.

Tha blue vortex beneath the engines looks so cool!

Very good! Can't wait for SLS to FLY!

Nice to see a win for Boeing and its great to have the kind of competition we have now, the new commercial space race!!!! SpaceX is some tough competition!

EARTH'S GRAVITY IS VERY STRONG & YOU NEED A LOT OF ENERGY TO OVERCOME IT'S 'GRAVITY WELL' ! ! !👍👍👍👍👍👍👍

The sound of those RS-25s takes me back...

That was epic!

Way to go Boeing and all the staff involved, you crushed it!

Amazing powerful test reminds me of the Space Shuttle Main Engine tests during the STS program of NASA.

A had a crush on a girl in high school and now she’s on the team working on this project. Holy moly this is surreal.

I wonder how fast a 8 minute burn with these engines would get the shuttle up to in space.

Not a single cloud in the sky to be seen until the test fire. NASA came to party!

In winter, that would be a massive snow-making machine...

[ninjafruit]

Looks like a fail, that building didn't even lift off the ground...
