When it comes to SpaceX, there's a never-ending stream of information available as advancements in space technology are made. Inevitably though, this information leads to questions as well. With Starship getting much closer to its very first orbital launch, SpaceX will need to start performing static fire tests using all 29 Raptor engines on the bottom of Super Heavy. This video looks at how SpaceX will perform these tests on Booster 4.

When do you think Starship will launch in 2022? - Shout out to CuriosityStream for supporting this vid! Check out curiositystream.com/PrimalSpace
I guess 2 explosions:
1rst in April at the liftoff still within 30 meter
2nd after several minutes in October
Launch? Or do something actually useful? (Like . . . not crashing or blowing up while achieving LEO, satellite delivery, moon landing, or a trip to Mars?)
April
Thank you for addressing the issue about the lack of any realistic flame diversion system at Boca Chica. Those tall tanks only a short distance to the north of the OLM, including the GSE tank farm with multiple huge tanks of LOX and liquid methane, do not appear adequately protected from the blast of thirty, plus or minus, Raptor engines firing for twenty or so seconds only a short distance away, without any blast diversion system. It would create a fireball of international news value and probably cause many $millions in damage.
If the booster reach more than 100m in the first orbital attempt it will be already very impressive with all the new systems and risks that SpaceX is taking.
This is not very wise, the booster has too many engines and they are very expensive.
I love how he is Casually saying "Only 14 tons of methane"
Hahahahaha...lmao
Lol 😆
"Way more engines".
It's great.
For just 3 seconds!
That A LOT of energy 😄
14 *TONS* of fuel in 3 seconds! 😮
Holy crap that's insane!
its like 16,92,481inr
The Space Shuttle solid rocket boosters burned 11,000 lbs per second, each, for a little over 2 minutes, and that doesn’t include what the Space Shuttle engines were burning.
@@rwfrench66GenX Sure but that was solid fuel. These are liquid engines that need to pump all that. Plenty of SRBs are more powerful than the largest liquid engines.
@@user-lv7ph7hs7l so why not use solid boosters?
@@rwfrench66GenX Many reasons. High thrust but low efficiency. Not really reusable. This is supposed to land and be reflown in an hour. Even refurbishing the Shuttle booster cost more than making new ones, because you have to completely rebuild them. A liquid engine can be throttled, which is critical too for landing. SRB is an easy fix for an overweight rocket to get of the pad but the liquid engines provide the actual performance to get to orbit. SRB's basically don't add deltaV, they just add thrust, so it can get off the ground while it burns enough fuel to go on without them. They are good for some situations but not for what Starship is trying to do (be fully and rapidly reusable, launch, land, quick inspection, refuel and go again until the tank dies from metal fatigue after a thousand launches. SRB are not compatible with "airliner-like reusability". They are cheap boom sticks, to give your expendable rocket a bit more oomph for a heavy payload. And you can't turn them off which comes with safety concerns (Russians don't consider SRB's safe for human use and never used them beyond ICBM's).
I can't wrap my head around starship. It's amazing the tech and manufacturing. GREAT vid!
Phly!!! Great seeing you here!!
Didn't expect to see phly here
And its a huge scam by Elon believed my millions of gullible sheep
Hey Phly tryin to join me at 8.3?
@@matttzzz2 how is it a scam?
This thing will have around 50% more thrust than the Saturn V did, which is just insane to think about. It's going to be crazy to watch this thing launch, and just as crazy to see them catch it on landing.
Agreed
I believe it’s also much more fuel efficient than Saturn V, correct?

I posted in another thread about something that was different with their testing, this sheds light on it. I live near the testing facility in Central Texas. Although we get the full blast tests every few days, over the last few weeks we have hear 3-4 second tests about 4 times a day. This tells me why they are doing that - thanks!
Cool to hear that!
The engines on the N-1 could not be test fired before launch as they lacked parts (I am pretty sure the valves had pyrotechnics involved where they were either on or off. But it is early in the morning and I could be wrong) that would allow them to be used multiple times. To try and skirt this issue, the soviets would test an engine or two per batch as an overall quality assurance check.
Didn't work.
@@garfieldirwin Thank you for your input.
So once a valve was turned "off" it was going to be off forever?
@@BobStein If I remember correctly the valves were turned off by default and required pyrotechnic actuators to turn them on (or something very similar). Once they were on, they were on until the first stage ran out of fuel or until the rocket staged. In the N-1's case though, it was when it exploded.
It was vibrational attenuation that tricked the computer into shutting down engines.
I truly cannot wait for the first full static fire of all of the booster rocket engines. It’s either going to end in a massive fireball from stress or a colossal success. We’ve seen plenty of renders of the booster having all of its rockets attached, but actually seeing them all together in real life like this is still hard to comprehend. It really paints a different picture from all the previous big rockets we’ve seen before. The eventual launch is going to be absolutely amazing, no matter when it happens.
Agreed 👌

If Soviets managed to get the flawed N1 design off the ground, I have hope for SpaceX. The lack of a flame trench is concerning though.
It's a bold move, that's for sure. I assume the thinking is that the vehicle will be made sufficiently robustly to not need one, and these lessons will make it more suitable for landing on unprepared regolith on Mars. Still, that's a *LOT* of force to design around.
@@Double_Vision The superheavy booster isn't going to Mars anytime soon, but I guess if they can make that work then doing the same to the upper stage will be a piece of cake.
@@thatguy7595 Precisely my point. They broke a Starship with flying Martyte in the past, and those lessons are now in Booster. Starship and Booster might be a rocket, but in reality they're going to have to work like a truck.
How hard is it to dig a hole with a shovel lol?
@@michaeljava8736 they don't want a flame trench because starship will land on mars on a flat ground so they want to know what could happen if starship were to land on mars
I cannot believe it managed to go so far with 5 engines out. Incredible work. So much data gathered now. Guess theyll be looking to why the stages didn't separate and how the Raptor engines can all reliably ignite and sustain good thrust. Should good for another launch hopefully soon!
I'm so glad we have people like this in the world. While I can't reach for the stars I can cheer them on from the sidelines. With gloom and doom around every corner it's guys like this that make it a little more bearable. This launch will truly be a sight to behold.
Billionaire lunatics who will corporatize space are not something making life more bearable.
I'll take NASA over SpaceX anyday of the week and twice on Sunday. They may be a bureaucratic mess, but their steady pace of advancement has made all of our proudest space exploration moments. Elon Musk is a snake oil salesman who is duping a new generation too gullible to see him for what he is--the world's richest liar.
@@mcs699 My impression of you in 10 years: "FUCK! Old Man was right!"
@@oldmandoinghighkicksonlyin1368 Yeah steady pace *snikers*. How much budget has NASA wasted on new space suits and what time frame with nothing to show ?
@@alexandervlaescu9901 agree
@@alexandervlaescu9901 Wasted NASA budget comes from every new president coming in and changing priorities for prestige projects. And I won't bother to list the accomplishments of NASA because they are far too numerous and you can look it up yourself.
If your main complaint is "space suits", you've obviously never looked at the engineering specs for the vacuum of space. It isn't as easy as putting on a onesy and rubber boots like SpaceX does for those on board the Dragon capsule.
I like how most of his videos are about spacex
Same
Cause they are the most Primal space rocket company. They are just fu**in doin it, just goin at it and innovating.
I still can't wrap my head around the fact that we have to basically start over from walking on the moon just 50 years prior is just amazing to me
6:15 I will never get over the fact that this is real footage and not a rendering. Absolutely incredible control of the vehicle.
@@GoblinUrNuts SN10 High altitude flight test. There's a video by spacex from 11 months ago. :)
EDIT: March 4 2021.
Every time I hear the conversation about colonizing Mars. I ask my self if we are willing to survive only by what we need, why don’t we have that same mentality on earth?
This is aside from “colonizing”
I’m talking about the ones who suggest on leaving earth for a “better” life
Such a good point. Surviving here on only what we need could truly eliminate a lot of the issues we would, in theory, be leaving behind.
I am very curious if Spacex is going for an all engines simulteneous static fire test. According to the info about the thrust of the Raptor-engine, i think the booster will be torn off of the engine-table when firing all 29Raptors at the same time. I say this not because i doubt the clamps on the table, but i doubt the strenght of the steel of the booster where the thrust-puck is situated.
The steel will be fine. It’s the footers I’m worried about. That kind of low frequency vibration can cause some serious liquification to the backfill. I can imagine the whole thing lifting out of the ground. But I’m no engineer when it comes to that sort of stuff.
If it flies successfully, Korolev's ghost will be seen dancing in the stars.
Actually I belive it was part of the ablative coating that blew up into the engine, the concrete below it was perfectly fine
Love these videos 👍🏽 very informative!
Really cool videos always! Check some of mine out, if you have an opportunity. I am an aspiring astronaut and am trying to share my journey with as large an audience as possible.
Watching this launch will be absolutely amazing but HEARING IT will be something else!
when one of these things blows up, you'll get to feel it too.
@@piccolo917 way to be optimistic
@@bogbog Musk plans to launch thousands of them. Currently, rockets have 4-10% failure rate, most of them happening on the ground. So, statistically, there will be an explosion. And with 4600 tons of liquid methane with all the oxygen it will to instantly ignite near it, that will be 46.000.000 * 55,5 MJ = 2553000000 MJ = 610 kilotons of TNT. For comparison, the Hiroshima bomb was 16 kilotons. Even if just 10% of that fuel explodes, that's almost 4 times more than the nuclear bomb.
So when I say "when one of these things blows up, you'll get to feel it too", I'm not "optimistic" but realistic.
I'm so excited for this launch. My life will never be the same.
2:41 its not that the soviets didn't have the infrastructure to static fire the n1, its because they coupdn't, the Engines on the N1 first stage used pyrotechnic valves and were single use, they tested 1 out of every 4 that were produced.
The main reason for the failures of the H1 rocket was the short deadlines set by the government and the rush to check the engines (there really wasn’t any). Also, after 4 unsuccessful launches, two more finished copies were built, but, unfortunately, they were dismantled for metal, because the Soviets considered the rocket pointless and unprofitable.
Watching this video a year after publishing is telling. Blows my mind that they knew the possible issues but decided to risk it. Makes me wonder if we would already be talking about the next planned launch date had the pad infrastructure been better.
If they manage to get all 29 lit and up to throttle on the first full attempt, that alone will be a miracle. Launching?
Don’t get me wrong, I am a huge private space launch advocate, and legacy-giant critic. SpaceX is my dream. But an actual launch in 2022… not just a hop, but a suborbital altitude launch… is still a huge undertaking. I would put it at the tail end of the year if they could do it, but expect delays into early 2023.
Brent Icenogle, how you guys doing in Boca?
you were absolutely right
2:34 the version of the n1s that flew had engines that used pyrotechnics to ignite so they physically couldn't fire the booster or even test individual engines prior to launch.
They did it! 31 Engine successful static fire!!!
The day the first Starship launches to Mars from Earth, i will watch it live with my mouth wide open, i can bet on that lol
The raptor engines exhaust totally 64 tons of mixture for 3 seconds only !!! This is insane !!
0.15 The Falcon 9's first launch went "perfectly" but it did not land as the video insinuates. The first landing was flight 20.
As phenomenal as SpaceX is doing already, there's still so many 'if's and unknowns regarding this monster.
Feels like they skipped a few steps.
i guess the man who lights the engines uses a long 7 inch firepplace match.instead of the shorter matches he got in the folder of them from Cowgirls Ranch (brass pole extra).
Add some rainbirds that spray a huge amount of foam to reduce sound and flame damage low level.
My ideas are often daft.
Very well put together!
Great video! No generic facts filler, just relevant info the whole way!
For a company that’s building Rockets space X looks more like a yard sale
I wish them great success, but looking at this I'm reminded of the Soviet N1 Super Heavy Lift Vehicle which was powered by no less than thirty NK-15 rocket engines. After four launches, they couldn't make that work.
I hope that SpaceX has been a strong and dedicated student of history.
You are right, but the main reason for the failures of the N1 rocket was the short deadlines set by the government and the rush to check the engines (there really wasn’t any). Also, after 4 unsuccessful launches, two more finished copies were built, but, unfortunately, they were dismantled for metal, because the Soviets considered the rocket pointless and unprofitable.
The last time I heard about the raptor engine was a report that SpaceX was forcing all the people making it to skip their Thanksgiving to continue production because they can't meet the quotas to make the engins economically viable
elon's hobby > human rights
what an amazing time to be alive
Yes! More of SpaceX please :)
Do you like elon musk
Rocket return : wing strech drop, arm catch, spline funnel drop, water bouyant , air craft thruster , parachutes, spring head ^impact,dual concentric barell vessels, retractable protection shell,etc etc.........
Rather go for engine variable size mass production.......
We will all feel it every corner of the world when this launches lol
Your content is so awesome
I'm more concerned about the Launch Pad itself...
Imagine Emperor Palpatine saying “now witness fire power of these 22 Full Flow Staged Combustion Raptor Engines”
That landing catch mechanism is very interesting.
I love the narrators calm, matter of fact, nothing to be surprised about tone ...
1:14 "For a typical 3 second static fire it would only need about 14 Tons of liquid Methane and 50 Tons of liquid Oxygen"
Now if we use Google Translate to translate that into everyday language we get:
" What the fucking FUCK ... 3 Fucking seconds ... *THREE MOTHERF@CKING SECONDS* *T-H-R-E-E* and 64 Tons of fuel & Oxidiser !!!! Thats over 21 Tons a second. *_FAARRRRRRRRRKKKKKKKKKKK_*
I am curious, for a rocket with so many engines, even at lowest throttle it must huge thrust.
How do they prevent booster from leaving ground during static fire
Tanks are filled with fuel, and/or other weights like water tanks are put on top
Usually weighted down and/or connected to the ground. I think during a Soyuz launch, the rocket is held by the supports it sits on and uses explosive bolts to separate and lift off
They make it so that the thrust to weight ratio is 1 or less
The booster is physically held to the pad by hold down clamps at the base of the vehicle. During launch these would disconnect and get pulled into the launch table for protection from the exhaust. Since its just a static fire thought they hold on the entire time.
Ratchet Straps
“The reason it has so many engines is because if 1 engine fail it can still work”
Sea dragon rocket: oh well, never mind 😳
How do they measure the thrust during a static fire?
Load Cells (Usually a transducer device with 4 strain gauges arranged into a Wheatstone Bridge and the resulting voltage(s) converted to the applied force/thrust)
I should also note that multiple load cells can be used together to determine the overall thrust vector of the engines since many rocket engines are gimbaled (can pivot/rotate to change their thrust vector)
I like the thought of 29 raptors on hamster wheels powering a space ship.
Goddamn watching those old starship videos makes clear how rapid the progress is with that rocket
It's incredibly interesting to me how the entire newspace industry is inextricably intertwined with failure. Failure and future. I can only imagine what it's like to be in the control room during tests. What I wouldn't give to be able to submit an ethnologic questionnaire to SpaceX employees!
It's always been that way
@@blazinchalice It very much has, and that is a really powerful factor to take into account when you think about what kind of people such a work environment attracts and how they interact with one another. It's like taking a bunch of overachievers, putting them (sometimes literally) in a tin can and shaking to see what happens.
just the amount of heat alone from them engine's HOLY SHIT!
What is the music in the beginning? It's none of the listed ones in the description :c
I found it myself, it's Sprightly Pursuit by Cooper Cannell
When you build your first big rocket in Kerbal Space Program
Other planets: not even your best engines can get to me bixtc
Love your videos bro.
Caught out of the sky?? They're going to catch the Starship like it's a frisbee???
Wow, so my Kerbal Space Program designs were right all along. Just put a shitload of engines on it. I'm a genius
I cant wait for spaceX to launch their first colony on mars
Absolutely Phenomenal!!!
i was not aware that they're going to catch this thing mid-air if they succeed omg
Could you imagine the look of disbelief if you told Apollo engineers back in 1969 that something the size of a Saturn V booster would guide itself back to earth then hover and be grabbed out of the air? 😄
Ah yes I finally found a video on the rocket which was designed by a decent science teacher
How informative!
The only thing Starship is missing is a giant toy box.
"29 Raptor engines" seems like a typical SFS player
The sound of 29 engines firing simultaneously will be insane 😎
33 now
Dude, catching that thing in its fall is a crazy concept. It will be so fragile. How do you catch such a thing? Huge foam pads?
Of course, what isn't said here is what happens when SpaceX attempts a fully fuelled orbital launch and then it explodes. South Padre is going to need a whole bunch of new windows.
So? Failures are expected. This is testing, that's what you want to happen.
@@filonin2 Failures are fine. Destroying other peoples property and showering people in broken glass isn't.
I remember when people said that when the Serial numbers where about to their high altitude hops. And talking about that since early May SpaceX people have been going around and photographing S Padre Isle. On the launch day all of S Padre will get a warning about the launch and if something bad happens there will clearly be compensation
Nice Video!
I can’t wait for one of these to blow up.
This channel is great =)
for 3 seconds ONLY needs 14 tons Liquid methane and 50 tons Liquid Oxygen. 3 seconds!!!
what would be even more amazing, is if you also used your platform to advise the space population to pressure the f.a.a to approve starship testing.
It will be a huge blast!!
Now they are gonna catch the rockets ! wow this is amazing ! 🤯
uhhh… well he predicted what happened.
29 rocket engines. Ok this is really interesting if it gets off ground. Las Vegas needs to make odds on this.more than likely will blow up pad. More than likely it will be a year or more. If ever it gets off ground
Will definitely be interesting to see either way!
it wasn't that the soviets didn't have the facilities to static fire the n1. it was that the n1 engines once turned on then turned off couldn't be started again.

Also, after 4 unsuccessful launches, two more finished copies were built, but, unfortunately, they were dismantled for metal, because the Soviets considered the rocket pointless and unprofitable.
Coming back after the 2nd ift, all 33 ran!
That bundle of rockets looks like the kind of nonsense i'd see in Kerbal Space Program. XD
Whoa whoa.....they're gonna catch it?
Like bundles of rocket tube nozzles of old sci fi pulps.
My fav channel. Thank you.
SIMPLESMENTE . INCRÍVEL ..
I think you should've mentioned that SpaceX did static fire a few engines on Booster 3
I love this video 🔥
Never been so early.
Btw music choice is great
It will be the excitement of the century.
Imagine how much further along we would be to colonizing the moon and mars if the space race continued at its original pace! We would 100% have people living on the moon by now and quite possibly mars as well!!! Crazy to think about where we might be if that were the case. 👍🏼🤯
Shouldnt the oxygen be the limiting reagent for the static fires? Or are they precise enough with the timing to not run the engines oxygen rich at the end of the fire.
Unfortunately for this particular issue, oxygen is abundantly available from another source, known as the Atmospherically Induced Reagent.
@@BobStein yes but isnt a methane fire outside of the engine better than the engine itself being oxidized?
@@k_Why The amount of oxidizer you have in a tank has literally nothing to do with how rich you choose to burn your engine unless you totally run out of methane, which they of course would not do.
@@filonin2 oh true hadnt thought about the fact that they dont need to run the methane tank dry. thanks for clearing up my misunderstanding
Truly amazing.
So if you let a whole village with 50k ppl all let eat burritos, and collect all their farts, how long will it take to start the starship?
When is the date of the test?
I hope it all works out well. That's a lot of eggs in one basket.
If it takes 14 tons of fuel to light the engines for 3 seconds, divide 14 by three and you need 4.6 tons for 1 second. and for a minute? 280 Tons.

man.. i wish one day in the future, people would join together and build every single piece of machine that was either still stuck only on the blue print or (like the N1) blown up to pieces.. they could build a sea dragon replica :v
