A critical test-firing of NASA’s Space Launch System moon rocket in Mississippi ended just 67 seconds after it began Saturday, well short of a planned eight-minute burn that was supposed to clear the way for the space agency to finally ship the rocket’s core stage to the Kennedy Space Center in Florida for launch preparations.
The SLS core stage, built by Boeing, lit its four Aerojet Rocketdyne RS-25 engines for the first time at 5:27 p.m. EST (4:27 p.m. CST; 2227 GMT) Saturday for a burn that was expected to last more than eight minutes, the culmination of a year-long series of checkouts at the Stennis Space Center in southern Mississippi.
Fastened to the mammoth B-2 test stand at Stennis, the 212-foot-tall (98-meter) SLS core stage throttled up to full power after the four main engines lit at 120-millisecond intervals.
The engines, leftovers from the space shuttle program, built up to 1.6 million pounds of thrust, making Saturday’s hot fire test the most powerful rocket firing at the Stennis Space Center since NASA tested the Apollo-era Saturn 5 moon rocket on the same stand in the 1960s.
But after rumbling to life and generating a ground-shaking thunder for a little more than a minute, the RS-25 engines cut off on command of the rocket’s on-board computer system, which detected an unspecified fault in one of the powerplants.

at this point why not just rebuild the Saturn V engines??
Pfffft, time to move back to NASA’s core mission, muslim outreach.
Won’t be much money to spend on something that can enrich humanity when there are so many social programs to fund.
“at this point why not just rebuild the Saturn V engines??”
They have plans, but most of the expertise is gone.
Forget NASA. Remember Obama’s appointee to head it. He said the most important mission of NASA was outreach to Muslims. Any real progress in space exploration will depend on the development of nuclear propulsion for travel within this solar system. The Biden crazies will never allow it. Musk and Space X would develop it but again the Biden crazies would stop them. A new dark age is dawning.
Yes, Space X would send a team in, grab the engines and rebuild them along with making them 30% more efficient and do it under budget and under time.
Then in their next hour on the job they would would grab a coffee, launch their own gear and call it a day.
NASA = We have stolen Hundereds of Trillions of dollars from joe public, and they still believe we are scientists.
Yep....a case of use it or lose it.
SLS is a bureaucrat/contractors dream, over promised, under delivered, behind schedule, way over budget.
Let’s throw more money at it , that will do the trick.
NASA should get out of the rocket building business all together. NASA should be restructured as a simple regulatory agency providing safety assurances to the rocket launching industry. Let private businesses like SpaceX build the rockets, launch them, and develope the missions needed for them.
The problem here is not NASA, it's that dumpster fire of a formerly great engineering company, Boeing.
BLOAT Boeing has been tied to fedgov for so long, it’s become a lot like fedgov
I’d rather spend the money on a carrier version of the A-10 for the Marines and Navy.
With the democrats in charge, we’re gonna need ‘em.
Look no further, lads.
67 seconds?
The good news...if the moon rocket engine cuts off after 67 seconds, the rocket will barely be off the ground and the crash will be nearby.
The bad news...with the rocket still full of fuel, the crash fire will be so intense, the crash remains will just be one massive puddle of melted metal.
No one knows how to use a slide rule anymore!
SpaceX is already building a FACTORY to churn out combination Saturn V + Space Shuttle equivalents, built of cheap steel and fully reusable. They’ll test the second stage this week. First stage is being constructed now, just a scaled up version of what they’ve been reusing for years.
And they’re doing it in tents on a beach.
SLS can’t even get past a single engine full cycle test.
Have they conducted their test on their version of the space station manned shuttle. SpaceX got 35% less than Boeing and are now about 18 months to two years ahead of Boeing.
My Dad (may he rest in peace) and I both worked at the Rocketdyne plant in Canoga Park, California, that built the Saturn V and the original Space Shuttle main engines. It was a point of pride at Rocketdyne that our engines always performed flawlessly. Rocketdyne was bought-out by General Dynamics, then Aerojet, then Boeing and the old rocket factory was torn down for a condominium complex. That’s progress for you.
More delays. A lot more tax payer dollars.
They did, and decided not to use them.
