Artemis Solid Rocket Booster made by Northrop Grumman - named the Booster Obsolescence and Life Extension (BOLE), and the largest SRB ever fired, suffered an anomaly during its test firing at the Promontory test site in Utah. During the final part of the two minute firing, the booster's nozzle suffered a major failure, liberating entirely from the motor.


The failure occurs at around 1:45 in the video...

they changed their name to YASA too. They felt it conveyed ethnic conformation and positivity.

"We observed an anomoly". Ya think?

Liberating entirely from the motor


I live rocket euphemisms. My favorite is litho-braking

I feel like we are getting to the point that if we are not careful, we are going to start moving the planet a bit when we strap these massive rockets to the earth and fire them up.

Rockets are one of the most impressive things humanity had ever made. Just insane, indescribable power.

That failure actually seems pretty constructive. They didn't lose the engine as a whole, and got some real data on how it reacts id there is a nozzle separation.

I ain’t gonna lie I ain’t putting my arse on any vehicle powered by a SRB built or contracted by NASA…..they’ve had issues with that and the tank since before the shuttle ever flew a single flight. I’m gonna hold tight and see what Elon does given the same amount of R&D time that NASA has had.

Not a "failure" per se, just a maximum unscheduled uncontrolled fuel burn off.

I haven’t heard that one, but it’s pretty good.

For some weird reason, I don't think this is going to be a problem for you...

Yeah, this could easily force Guam to tip over, even without overpopulation.

Hawaii has a higher center of gravity.

FTR, the shuttle flew 135 missions. Only one (STS-51L) failed due to the SRBs - which Thiokol engineers forewarned NASA that the o-rings were incapable of functioning in temps that cold. That was all on stoopid NASA mgmt. SpaceX has flown 18 manned flights.

I think SpaceX Falcon-Dragon flies with 1/500 risk of catastrophic failure. The Shuttle was flying with about 1/250 at the end of the program.

Of course not….it won’t be a problem for anyone in this thread but hypotheticals are what this site is all about.

So twice as good as NASA already….and SpaceX has been designing for what a decade or so now? Give them 40 yrs and see what they come up with.
