- The RS-25 rocket engine had a “500-second test on the A-1 Test Stand at NASA’s Stennis Space Center in Mississippi,” according to space agency. Four of these engines will be able to produce 2 million pounds of thrust for the Space Launch System (SLS) rocket.

5, 4, 3, 2, 1, ignition. And we have liftoff of a NASA test stand. I keep waiting for that to happen lol
@Rishabh Gangadeen We Call it skycities
I used to work for Rolls Royce and managed to talk my way into visiting the test beds once. One of the old timers there said that Pratt and Whitney asked to borrow their facility to test one of their development engines and the thing either wasn't bolted down properly or their engineers had grossly miscalculated the amount of thrust it would produce. The result? They found it about a mile and a half away in the middle of a golf course. They even showed me the wall it punched through, you could clearly see a patch about 4' in diameter that'd been filled in. One of the best stories I have from that place. Ha ha.
🤣🤣
15 seconds to main test stand seperation and second stage ignition.
"this is test stand, we have MAX Q!"
When you think about it, it's absolutely amazing that this engine is so cold right after test firing, that you dare not touch it because your hand would freeze to it. Instant frostbite.
The cryogenic cooling system is incredibly effective.
@@TheRjjrjjr it's not fuel. It's liquid Oxygen !!
@Hank Hildebrant new molecule you farted ? 😆
@@frederic.marquis7361 No, the SSME is indeed cooled by the liquid hydrogen fuel.
@Hank Hildebrant hey jerk !! What's lox if not liquid oxygen ??
@@LunarDelta yeah I know. But you know in France liquid oxygen or liquid hydrogen are considered as gases like nitrogen.
When we talk about fuel we mean much more gasoline and petrol...
Guess you guys are lucky to have a building that weighs 2 million and one pounds.
I want to see the bolts holding that together!
@selphie Don't forget JB weld
@selphie not duct tape..
But flex tape
that was only one of four engines that will produce the 2 million pounds of thrust, so technically it's only half a million per each, but comment is funny anyway :D
I now just imagine trying to pick the building up and it weighing only 1 pound while the engine is firing :D
Never gets old. This is extreme engineering at it’s finest.
and the most expensive to date.
The RS-25 is a beast
@@BeKindToBirds I would love to attend a launch. I believe it would be an exiting thing to watch.
@@AlbertLebel only 5 months to launch now !
Fascinating: the buildup of ice on the outside of the nozzle, right after ignition. Outside freezing cold, inside glowing hot.
And that's what she said 😛
lolle18 that's what happens when you run a lot of little tubes full of liquid hydrogen around the outside of the nozzle to stop it melting. Hell of a temperature differential.
Touch it if you think it's cold lol. It won't hurt🤣🤣
lolle18 Fire and ice = GOT
Hydrogen
Notice how the outside gets really cold once it ignites. I've heard rumors that in theory you could go up to the rocket while its going full blast and touch the outside of it and it will be cold due to it using its own really cold fuel as insulation and protection. Engineering at it's finest.
Not quite, the sound is loud enough to shatter your skull, that is why a lot of water is discharged beneath the engine on a test stand, and a rocket being launched. Otherwise the sound waves would reflect back towards the rocket and destroy it before it could lift off. The bell also reaches 1,000 degreed F while the engine is operating.
Let me know when you will be doing it. It can be fun watxhing you do it. Lol
@@taraswertelecki7874 yeah i forgot what this is called... That's why water is pumped through the flame deflector...
Sorry I missed it, I was in my office. I could feel the building shaking though. I've seen a bunch of these, the best were the night firings.
8:30 Love the mystical Mach diamond deciding it's had enough... "No more fuel and we haven’t even left the ground yet? You can kiss your precious “specific impulse” goodbye, its nondescript momentum you’ll be seeing from now on matey” *hiss*
So glad to hear this is done in the state of Ms. It's a much needed project for a mostly over looked state.

@Hank Hildebrant r/woooosh
@@cr15py72 Pretty sure it's a cloud of water vapor...
@@Inertia888 Yes, becaeuse the fuel is liquid hydrogen
Hear that "whoo" at 8:31? You can hear that for miles.
really? wow
That’s the engine calming down
What I find fascinating is that photons can travel unimpeded through that column of violence (just post cone), with no lensing effects. Even natural daylight from outside is passing with little impedance. I would hazard a guess that the Bernoulli effect lowers the pressure enough in that area (due to speed), that the shock front cannot form yet against the 1 bar atmosphere?
Indeed.............
Hmm yes. Shallow and pedantic
@@philipzw czcams.com/video/OpbdGnJbneE/video.html
Think you’re conflating things, perhaps purposefully
Yes that's exactly what everyone else finds fascinating. For your next video I would have to recommend the Dunning-Kruger effect Zaphod Breeblebrox
I love how the nozzle gets cold instead of glowing red-hot. They do cool the nozzle with the cold propellant if I'm not mistaken.
That is correct.
They use the fuel to cool it down. I slightly remember a video (i think it was from nasa) explaining why the nozzle not melting.
they create small pipeline accross the nozzle (as part of it). and run the fuel into it. So it was multi purpose.
We get it, you vape
haha
ah I see you're a man of culture aswell
Surya Haris Senoaji Hahaha
r/whoooosh
awesome
You thing that building would of lifted and went to Mars lol , They bolted that down well .
Building: I believe I can fly...
Vaper : my smokes aren't as much as you think
*The smokes:
I wonder what happened to the ground directly below the nozzle.
There is no ground below, there is something called a flame deflector, i. Which water is pumped. Water is pumped even where the flame of the engine hits. After that the flame is deflected through a flame deflector which is like a waterfall... So the groung is intact
@@kapilasharma5080 badass
That so wants to go UP - amazing how much construction around it to stop it going UP. I am amazed how pipes etc above the engine aren't broken by the sheer force pushing up
And that's just ONE engine...
Imagine what happens with four of these bad boys
@@spinningsquare1325 and 2 srbs o-o
One! Just watch the Rocketdyne f1 test where four of these were running... Man...
@@kapilasharma5080 nah watch the whole booster being test fired. All five engines
@@spinningsquare1325 yea ok
Just the fact of the building not shaking itself to death is an amazing feat of engineering all on it's own!
But the other really impressive thing is the stability of the camera !
I mean the velocity of the air around that rocket is just clear off the chart. . . .well not technically off the chart, they know exactly what it is but you know what I'm gettin at. . . . . Ludicrous speed!!
We drove to the Stennis space center one time. Totally on accident, they were doing a test firing. Of a single engine of some kind. It was back in 1994 so who knows what kind of engine it was. Anyway, we were *miles* away. Couldn't see anything. But the noise was so loud it rattled all the car windows around us. Just one single engine. It was incredible.
When u get in your car and finally let rip after holding it in the entire date
Bruh
True though
I *love* the little red flame at the end, once the oxygen stops running. Burning the bajesus out of any other gases that somehow found their way around the nozzle during the test. :D
This video was posted 3 years ago, but I also think it will take another 3 years at least to see SLS with cargo on the way to trans lunar orbit. If this idea wont be scraped obviously.
BEAUTIFUL SHOCK DIAMOND PROJECTING FROM THE NOZZLE ! ! ! ONE OF THE MOST BEAUTIFUL THINGS IN ENGINEERING YOU CAN SEE ! ! !
Now THATS a Mississippi Sauna!
That’s the Power of Power!!!! Amazing stuff from NASA 💪🏼
What an absolute BEAST!
The title should says:

Arvin Time to create a rocket engine in my garage!
- rocket engines are cool
charles wrobel hmmm....no thay are really hot.........😂😀
smackmymonkey the exhaust is hot but ice builds up on the nozzle, they aren't cool or hot, the engine is cold. lol
No rocket engineer would advice getting into that field so i'd have to disagree. You work endless hours to see an engine burn for 8 mins, very cool yeh?
0:10 in the toilet during severe diarheaa
I got the the same sort of thrust from that £24.99 induction kit from Halfords that I fitted to my 1.1 popular plus fiesta..... 🙄
When You Gonna Fart Slowly In Public
Oh boy, I can't wait to see this rocket engine fly again in 2018!
Holy cow, what are the neighbours doing today?
ten miles away in every direction
🇺🇸💖🇬🇧😃👍👍👍👍💖
Amazing. The engineering behind this..and this is only 1 of several to be deployed to a rocket into orbit.
I’ve been their. In fact I live about 30 miles from it
awesome, and saturn 5's F1 engine is 4 times more powerful? mind boggling
Rocketdyne F-1 engine is huge. Saw some at Kennedy. Unbelievable. 1.2 million pounds of thrust, each.
It’s amazing to see the nozzle with all that super extreme heat, but frozen cold at the same time. 👍
Note how frozen the nozzle surface is despite the superheated plume it is blasting. Designed to heat and cool at the same time.
Jest moc! Powodzenia w podboju kosmosu!
Damn!!! What do you think that thing will do in a quarter mile? : )
Crazy to think that you could potentially get frostbite on one hand and the other burnt off at the same time. Assuming you can get close enough to the nozzle that is, pretty sure the pressure waves created by the sound would kill you LONG before you got that close.
I'm curious if it starts to rain sometimes with this amount of "produced clouds".
can u imagine what 4 of these will sound like when they test them? i still think the closest thing to what HELL actually looks like is when they tested all 5 of the Saturn V F-1 engines
Amazing engineering.
Barely controlled hell on the inside of that engine and the outside frosts up.
Atleast now I know what my team mates microphone looks like.
You know, if you built these test sites in areas where there is severe drought ..... you'd be able to really tease the locals that are longing to see rain clouds 😂
Talk about power! sheer power!
my neighborhood association would love that😜in my yard
Soothing.
As a meteorologist I will say that this amount of evaporated and heated water would easily have the chance to generate a modest downwind shower, in case of sufficient local thermal instability.
worldbestpilot It does.
This video is just freaggin cool. The white cone in the exhaust... is that plasma. Anybody know?...
Dat funny looking rocket never even got off Davidnfloyd124 ground
Love this....takes me back to the Apollo program....sexy engineering!
Its all fun and games until the whole building gets launched into space
Trying to hotbox the whole earth lol.
Put that rocket on the back of a truck, and we got "supersonic truck"
Supersonic truck for ~0.01 seconds, supersonic fragments thereafter! :D
I wonder what would happen if we mount it on those huge ass freight ships¿¿¿¿
It would look like a protester being hit with a fire hose. lol
will this fit in my honda?
Attach that badboy to a Pickup truck
Rolling steam, not coal!
Yeee-haw🤠
Pickup with rocket engine running on 104% thrust: 2 mph
You just can't get it moving
I had those same thoughts when I was 5. It just isn’t that economical
or use 1 or 2 of the updated Apollo era F1A engines which produced 1.8 million pounds of thrust each
Richard Ryerson but those burn kerosene and these burn hydrogen, I think they are trying to go for a cleaner burn.
It's more about having a higher ISP in vacuum actually.
The main stage matters more higher up outside the atmosphere.
or use 27 merlins for almost 18 million pounds lol
nobody 5.1 million
Making the rocketdyne F1 proud
Ehh...eh...this things turning out roughly a fifth or a quarter of the the F-1s power? Idk, its somewhere in there, im to lazy to do the real man lol
F-1: 6,770kN (SL) 7,770kN (Vac)
Rs-25: 1,860kN (SL) 2,279kN (Vac)
But its still defiently neat!
Now just imagine 5 of these underneath one rocket..😳 holy fuck that’s the ride of your life! Not to mention the two solid rocket boosters they’re strapping to the side of this thing 😱😱😱 if it blows it would take out at least 8 miles of shit clean.
Not to put a damper on things, but these engines are puny compared to the old F1 engines. If 4 of these produce 2 million pounds of thrust, compare that with 7 million from 5 F1. Seems like a total waste of money. This is a step back not forward.
They could have modernized the F1 and improved it for a lot less. Tried and true workhorse for then, now and the future.
jaygensn1 im pretty sure they do this to improve vac isp since hydrogen is much more efficient than RP-1, also, sls will be attached with SRBs whilst the S5 surely did not have any SRBs.
they did, but the f1 was a fuel guzzler (f1-A)
Literally rocket science....
I mean what else would it be? Agriculture?
+BrandonFleming
Actually, with this much water vapor going locally into the atmosphere (hint hint, it's gonna rain), it might as well be.
It’s not exactly rocket science, it’s only liquids hydrogen injected on honeycomb made ceramic material .
Those engine have NO spinning turbine in it . Only hydrogen injected on ceramic .
I have made one several years ago , it was 1/4 inch diameter and the cone was 2 inch and thrust was over 300LBS
ah, i didn't think of that. Excuse my idiot comment.
Lindo espetáculo, na terra tudo é possível, quando irão pra lua de verdade?
At :15 you can see a gantry device going under the nozzle. Planned or not? If so what is its purpose?
The structure in that building has to be very strong to support that amount of force.
RS-25 Space Shuttle engine!
Watched these same engines tested in the 80's
More engines, more power, more kerbals.
Engine was held in place by JB weld
I'd like to hang out in that building, right on the balcony, mix up my innards into jelly.
SpaceX Merlin 1D engine produce 200,000LBf of thrust. This one does 2x more at 418,000LBf.
I wonder when the 4x cluster test is coming...
soon.
Soon™

But I dont wanna wait that long!
They should rebuild the Saturn V with these on the second stage. They could lift entire space station modules and interplanetary space craft into orbit.
LH2 + LOX = wow!(signal 1977)
My neighbor needs to move their house abt 6 ft from the exhaust hole.....to make sure everything's working A OK.....for my amusement for one.....can't think of any other reason🤣
I wonder how many decibels are in that room where the rocket is, maybe 200?
Can't wait till NASA to get Mars with SpaceX
Dangelo Johnson NASA is not working on Mars with space x
What is that arm that swings under it at the very beginning?
When you put liquid oxygen in your stove's gas tank and it liftoffs; *m e k a n i k*
Well, it works!
This engine looks like a KSP vector engine ( I know that it was inspired in this)

This push against the earth has get us 100km further away from the sun, in 6 weeks we all die..
Kwa ndo I hope your joking but if your not, this has nowhere near enough thrust to do anything to the earth orbit.
+Casey McMasters
It's pointed at the ground...
You can't power a sailing ship by blowing into the sails...
And even if it was pointed up, the exhaust wouldn't even leave the planet (or knock any significant amount of atmosphere off)...
If its thrusts wasn't nullified by our atmosphere and our gravity, it _would_ change Earth's orbit. It would be so slight that we wouldn't notice, but it would change it.
So despite arguing for a true statement, your reasoning is ever so slightly flawed.
(Then again, maybe you're just rounding down... after all, if we can't even measure the difference with our most sensitive sensors, can we truly say there is even a difference at all? So if that's what you meant, your reasoning isn't flawed. Still, you should have probably mentioned that it's not actually applying any thrust to the Earth as a whole.)
That would be 500,000 pounds/thrust each.
this would be good for a dj lighting setup
Now THAT'S my kinda thinking. tubedubber.com/?q=UEhHRXDFkeU:A1t3NrONZuA:45:100:0:11:1#
Turn it up!! Turn it up!!
WHY DID I WATCH THIS LIKE 40 TIMES!!! WONDERFUL UPLOAD.
This is type of engine, you fell in love forever
For anyone who asked how clouds are made
And these are only about one third of the power of a Saturn V F-1 engine. They're still impressive.
THIS IS TOOOO AMAZING!! 😄 I bet that'll cook a hot dog in no time flat, I'll bring the marshmallows too 😂
valenius the kat I think it would get soggy. 😝
And a little charred ♨😄
You hot dog would get poached as it gets steamed.
