It really delivers a trust of thrust I believe in 👍
In this context cheating math by physicalisation is like magic for me , but it works well for me.
We are so limited by gravitational force be design , very good the right outside of our atmosphere we face less gravity

Thank you for all you do. I am 81 years old and live near Boca Chica. I love all of this. Don't understand a lot but have learned a lot also. Keep the info coming.
I got to go down to Boca Chica during the sn10 days. It must be great to live nearby during the ramp-up to orbital flight testing.
Bless you Linda. Glad we’re all learning together.
You are witnessing, history in the making. Greetings from Malta.
I'm surprised ubcan even use RUclips let alone know about starship...
No human from earth ever made it through the firmament to outer space and everything they say about going to moon is a lie!
This is why, when I lived in Waco, Texas for 20 years, the entire city shook sometimes, with a low roar in the distance. If it was night, it looked like the sun was rising in the distance. They were testing the Raptor engine at the Space X facility in Mc Gregor, just outside of Waco.
Super enjoyed this one, thanks :) The clear, concise, well paced explanation didn't hurt my brain. Still had to re-wind & re-watch a few segments for comprehension & retention so awesome job...you learned me good!!! ')
The best teachers have your skill. Breakdown the complex into understandable pieces, then complete the jigsaw. Thank you, your turn learning from a boring chore into an exciting adventure. I'm hooked.
One more very important thing why SpaceX developed the Raptor:
They needed a high-performance methane-burning enginge, because it's possible to produce methane on mars using in-situ resource utilization, and refilling Starship there to have a return vessel. After all, Starship's real mission is the mars, and everything around that rocket is optimized for that mission.
Do viewers of this channel notice the scammers posting rely on everyone comments asking them to call for personal consultation. The first red flag 🚩 no honest content creators put their phone number phone number out in public like that!😂🤣😂
That's THE reason
Dude that is just a silly pipe dream. The reason is to send up starlink so high frequency traders can destabilize the economy a few microseconds faster.
Well they better build something bigger because their "starship" can barely carry a full crews weight let alone the materials they'll need to make it there. Who needs water and food or toilets or beds for a months long trip in space anyway. Just more vaporware from the king of it. N here you are thinking he's gonna magically make methane to refuel, the cult is real
@@joshlewis575 The hard part is not getting there. It's getting back and even worse doing something worthwhile on Mars. Getting to Mars and die quicker or slower in misery is a possible.
Honestly, I’ve watched almost all of the Everyday Astronaut videos, and this is the first time I actually feel like I have a general understanding of the systems. The way you explain things I so straight forward and understandable. You made something complex sound simple. I think you have a serious talent for this. I’m impressed. Thank you!
He os only yellow = not Human but is closer to Human than the hyper verbose and stupid host over at everyday astronaut.
+1
Agree the concept/idea was digestible .
😄
You're easily impressed... the audio and visual screw-ups did not impress me. The Everyday Astronaut would have corrected errors that this guy just ignores... mediocre at best... and he or she's had three weeks to correct the mistakes, but clearly D. G. a S * * T.
Great to hear technical people who prioritize simplification! More fiddly bits translate to more problems.
Funny how much you think you know until someone takes the time to break it down a little more and then focus on the smaller topics one by one. Excellent stuff. Subscribed.
Good smooth presentation. I can remember the US Navy Vanguard blowing up on the pad. My dad made parts for Explorer one launched by the Army on a Jupiter-C Rocket. That was on Jan. 31, 1958.
Really love the approach with explaining complex things. Also thanks for the attributions to other creators' works.
Thank you! You explanation for me was spot on. Your flow and pace was perfect for me and I was able to keep up and understand. So well done.
I learned a lot, which is GREAT. I knew the engines were complex, but had no idea how oxygen and fuel were mixed before igniting. Thanks for taking the time to share.
Amazing, extraordinary work. I look forward to every episode especially about RAPTOR!
Another clear explanation of the full-flow engine. Appreciate learning rocket science from you.
I watched a higher level talk with Elon the other day and had about an 80% PSA rating. (Old airline which flew "over our heads" in CA every day.) This one hurt less. ;)
I enjoyed the video. Can you cover something related to how the engines are connected to the structure and how the nozzles are synced and interconnected for directional use?
Good simplifications! Well done. I can use this with STEM students.
@2:07 Liquid oxygen is not used for every rocket. Other oxidizers include: nitrogen tetraoxide, fuming nitric acid, nitrous oxide, or even fluorine.
Is it drinkeable?
@@zsolti. none of them are drinkable.
If your crazy or communist you use such oxidants in a first stage.
@@zsolti. "Is it drinkeable?"
Yes. You are unlikely to survive doing so.
How could you forget about the OG oxidizer, high-test hydrogen peroxide?
I was allowed to stay up to listen to the first moon landing. With all my space books and artistic impressions of what the future held it was a dreamy and exciting time for a child of the 60's and 70's. And then nothing very futuristic happened for so long. I might not be around for the colonization of mars but things are exciting again, Space X and Tesla like a long awaited sequel to a great book. It's brilliant to be dreaming again and have a channel like The Tesla Space that shares and gives insight and understanding to this new era of human advancement.
Just like Elon doesn't believe in unnecessary complexity with manufacturing this channel is sharing an understanding to everyone according to a philosophy of inclusiveness.
Well put!
I remember Sputnik, and everyone feeling threatened by Russia, then the space race, blown up school teachers and streaks across the sky, as tiles fell off. Its good to see someone else foot most of the bills, and not blow up people.
It seems like it would have been a good idea to have done an engine swap on the falcon 9 if only to have been flight testing the Raptor engines, I know that it may have taken time away from the Starship but it could have been a different kind of Falcon Heavy without the two extra boosters. I also know that the starship will be replacing just about everything when it starts flying.
One of the greatest video from you. Super valuable content. it's pleasure to see the video. Appreciated.
Spectacular presentation. Truly fantastic. You make things more understandable than I thought was possible. Outstanding job. Excellent pacing on your speech. Very easy to follow. Solid A+
Minor correction around 10:20 -- Elon said they were able to remove the torch igniters. He did NOT say that the fuel and oxidizer would autocombust. (That's the domain of hypergolic fuel mixtures, which methalox is not.) Among those details which Elon would not discuss is some other undisclosed mechanism of causing ignition.
Big props for using so many _clearly attributed_ Everyday Astronaut clips, too! Too many RUclipsrs bury credits like that in the description, if they bother to include it at all.
I wondered about the ignition as well thinking Diesel type? ignition. Maybe a magnetic induction (so no combustion chamber penetration) ceramic glow plug? I would imagine it being kind of like starting up a propane torch, the pressure has to be low at first, then the gas can be increased. I really have no idea.
Thanks for the clarification !
What an Amazing Video !! You obviously did so much research so you could add so much info to this Video for those of us who love the Rocket Industry but know very little about it. You did an Amazing job with this. Stay safe. Cheers ! 😎
Thanks for your video which contributes a lot for understanding how a rocket engine works.
Thanks for the clear, understandable descriptions. Please make another video on the cooling system.
Gotta say, reminds me a bit of the development of the German rockets and the fuel issues they had. What I find similar is that there is a simplicity involved. These engines are "basic" but that does not make them easy to engineer.
Yes, they copied the same tech from other worlds. We want to see Elon go up in the rocket.
Engineer or to make. I am a aerospace machinist and these Raptor Turbo Pumps are some of the tightest tolerances to hold along with the material being hard as heck. It's cool making these though.
Wow. Fantastic video. Really easy to understand a d great graphics. Love it. Thank You.
Pretty exciting stuff I can’t wait to see it come to life!
Good breakdown. Full-reusability for the first few rounds of Mars-bound Starships is unnecessary -- they ain't coming back -- but absolutely essential for generating the funding for those ships (Earth-bound Starlink and commercial launches).
@@randombutrelevant1606 Honest question: we both know what you posted is pure BS, so tell me the real reason you hate Musk. Did he put your company out of business; or did you lose your money shorting his stock; or did he take your girlfriend? Which is it?
Not beyond unprecedented. N1 first stage had 30, which I think were also closed cycle engines.
That closed cycle is not this closed cycle. N1's close cycle was a oxygen rich combustion. It burns more oxygen than is required. Raptor burns methane and oxygen in correct ratio without waste. Raptor is more efficient in fuel consumption.
The HEAVY is so massive. I remember as a child how massive the moon rocket was. The heavy is many times that size. So in a few decades I hope to be alive to personally observe the incredible size of this rocket in a spaceX museum in Florida some day.
No human from earth ever made it through the firmament to outer space and everything they say about going to moon is a lie!
I'm so fascinated!!!! Awesome Documentary.
Why is this video on The Tesla Space rather than The Space Race?
Thought the same thing
Excellent presentation! Even I managed to follow your explanation ;) Hope you will do some follow ups, too!
Great lecture and information ! Thank you !
Excellent explanation of a very complicated subject. Amazing Elon/SpaceX design !!!
Musk didnt design anything. He isnt an engineer.
Excellent presentation, keep moving forward, allow for the negativity. It's just the level of human beingness at this time.
@Text Me∓¹⁹⁴⁰²⁰⁸⁰⁶⁸⁸
Monkey scam
Excellent excellent video. Just the right level of technical detail at the right time.
I do have a question about the shroud that Elon wants to remove. Can you do a video discussing where it is, what it looks like and benefits of removing it?
It's just a heat shield and the benefit of removing it is pretty obvious: less to manufacture, less to install, less weight.
To remove it requires increasing the heat resistance of a few components and, possibly, redirecting some of the existing heat flow. More detail hasn't been shared by Musk.
@@lighthousesaunders7242 Its not like he is an engineer. He just wants to save money.
The main benefit of removing the shroud is simply weight reduction for the rocket. Less weight to be lifted less weight to catch.
Very interesting and easy to understand information that I thank you for sharing with us in such an entertaining way 😀
Bravo. Excellent presentation.
I have visions of the Soviet N1 rocket (always blew up) which had 30 engines on first stage. Hope Elon gets it to work, but if have that many engines and if each engine has even 1% chance of catastrophic failure then you have 33% chance of flaming data per first stage launch for Starship...I suspect he is working mostly on reliability at this point.
It's a pitty that first Starship launch repeated unsuccesful Soviet moon rocket N1 launches. 😢 And some Raptor engines refused to function correctly...
Maybe great for a lot of people who were not following the development
Couple more questions would be great to cover, mainly how is raptor restarted for landing?
The outer ring of 20 engines are started only by ground-based equipment, but the inner cluster of 13 have individual spin-up and ignition systems. The latter are used for the boost-back burn and landing.
The only reason is that he doesn't know where to spend the money from NASA.
What intrigues me is that all the UFO visualizations and some captured in video and photos, are of round or triangular spaceships and due to the immensity of lights there has to be a generation source that will violate the damn laws of thermodynamics that are strangling the advance of science, why is it then that humans keep their designs based on rockets, hungry for fuel and slow as snails.
Great explaination ! 🖖
WOW! AWESOME! What a clear explanation!😀
I noticed that in a test yesterday while only using 14 booster engines that there was serious damage to the concrete launch pad. How are you going to deal with that problem when you go to 33 booster engines?
Hello, I'm from the future and... they didn't deal with that problem lol
You were correct.
I wish I could get Elon's mind ticking over this potential improvement in the heat shield tiles, we have all seen some fall off the ships when being moved around without firing up a single Raptor, I hate to think how many will fail. I've been studying the structure of scales on fish, particularly Salmon in their fight to swim against the current, the overlap of the scales is key to this proposal. They have one anchor point, a Titanium bolt would help maintain the scales and reduce the additional weight of the scales when overlapped, these anchors can be reused again and again. If one scale shaped tile separates the tiles underneath will maintain the integrity of the shield, might as well try new ideas to improve the shield before a manned encounter with massive windshear at speed in Earth's atmosphere or entering Mars thin but still violent gas. I sincerely hope the current arrangement can withstand re-entry, but I am sure your team are concerned when the first automated flight destined to return to Boca Chica, the first to be inspected at Mechazilla we hope.
hey do you have any research gate or scholar profile? your work sounds really interesting although our field of study wont match, im working on rough surface of airfoil, I really want to read the paper
I wish I was a young engineer again. I began my engineering degree in 1970 and want to be a rocket engineer. I was building my own rocket engines and rockets in the late 60's and I so much wanted to be part of the moon space program. Really happy someone is back into doing space to other planets with people again.
Great job! Easy to understand video!
1:15 it says everday astronaut, not everyday astronaut
What cracks me up about Elon Musk is every boy at some stage wanted to be an Astronaut. Elon Musk actually created his own Rocket Company?! I mean WTF who does that?! Total Boss Move....
Elon reminds of what Robert Schuller said, "Make your dreams big enough for God to fit in."
so well explained, thankyou,Rod
Amazing! Thinking outside the box, not always following what has gone before.
The only man i respect in the entrepreneurship space is Elon musk. To a lot he is a maniac but to me he is my hero. In one of his interviews he mentioned about mining Doge coin done by people like Teresa Janette Brock I recognized that mining is one of the methods used by the wealthy to increase their wealth. In only 6 weeks, I've already made a fortune. You may either establish your own mining farm or mine on a cloud network. With this era's transformation, there is a lot to profit from.
Love to hear more about the turbo pumps...like how is it possible to generate so much pressure from a single stage its a fascinating video....thanks
The turbo pumps rely on the same principal that a turbo charger in your car does. Instead of air, its pumping fuel. When a liquid becomes a gas the volume increases. in the pre-burner you change the liquid fuel and oxidizer into a gas and direct that expansion pressure into a turbine, which in turn pumps more liquid fuel into the pre-burner to phase change into a gas. The pre-burner turbine is linked to the pump by a shaft, so when the turbine turns so does the pump. All the pumping work is done by the phase change from liquid to gas, then we take those gases and put them into a combustion chamber were we can burn them.
Think of it like steam. You boil water in a closed chamber and it turns into steam. If you don't vent the steam you build up incredible pressure and the container will eventually fail and explode. But, if you open a small hole and vent the steam you can take advantage of that pressure to do mechanical work. Much like a steam train engine, except on a rocket we use fuel and oxidizer that we can burn at the end for even more power.
@@Amehdion ah thanks. That's fascinating, actually making use of the phase change latent heat. Brilliant.
Outstanding video.
Well done and keep up the good work
Great video! You might've just gotten 50k more people into following this work.
The concentration of engines is not unprecedented, the soviet N-1 moon rocket had 30 on the first stage.
They also conceived a veritable flying saucer. Although pretty cool, it doesn't seem to be in commercial use either (that we know of 🤔). However, if you're only referring to precedent, I cannot disagree.
0:45 the soviet N1 rocket had 30 engines, it is actually a fairly similar design... Let's get facts straight
what most don't know is that the Russians where and still are amazing engineers, when you observe SUKO and MIG they are very advanced and a power to recon with
\
@@arlandgaylor good engines but limited with budgets and poor management.
Simply put -> Great!
Well researched video especially considering its outside your usual niche
One of the biggest benefits of reducing complexity is increasing reliability.
You are great my dear, I thank you all my dear big fans, you all are making me proud and I promise you all that I will do more in the world 🌎 if you need your own Tesla project and I will always do the best in the world 🌎💯 I am still praying to God so I can provide more in the world
Raptor 2 save 1 ton weight per engine then makes 1/2 as much again in thrust. Which has to bd worth another 1/2 ton of weight. Fit 32 of them against 48 Shuttle engines and you’ll save about - erm - at least 50 tones of dead weight. That’s at least 50 tons more cargo you can carry for the same fuel burn.
The only reason is that he doesn't know where to spend the money from NASA.
What intrigues me is that all the UFO visualizations and some captured in video and photos, are of round or triangular spaceships and due to the immensity of lights there has to be a generation source that will violate the damn laws of thermodynamics that are strangling the advance of science, why is it then that humans keep their designs based on rockets, hungry for fuel and slow as snails.
Shuttle engines use hydrogen which is 25% more efficient than methane so your added "dead weight" brings a higher payload to leo and especially anything beyond leo
Thankyouthankyou
This really helped me understand a number of aspects of his strategies
Awesomeness! I actually understood what you're explaining! I'm your new subscriber...
Not even a thank you to Tim Dodd, Everyday Astronaut? Half this video is hosted from him. That’s not cool.
What's most impressive is that the CEO himself gets in there and explains the technical details. I'm sure he does not know how to actually design the engines, but can explain their operation. His "keep it simple" mantra reminds me of an early American inventor, "Madman Muntz." Muntz was a self-taught electrical engineer who would visit his engineer's labs with a pair of side cutters in hand. He would cut one component at a time out of the system until it finally failed to operate. At that point, he said "put that last part back and then ship it." They called it "Muntzing." Elon's desire to simplify, simplify, simplify is a modern day version of Muntzing!
No wonder he's called a madman. There's no possibility his method would produce a high-quality product.
@@guitarista666 Back then, when a new TV set was quite expensive ($150), a $100 Muntz TV was considered a bargain. It had few amplifier tubes, so it could not pull in distant signals. Muntz realized that most sets were sold in urban environments where TV signals are strong. Anyone needing a TV for out in the sticks was left to buy a more expensive TV from RCA that had more tubes. I.e., your "high quality" comes with a high price tag. Most people favor price over quality. It was a very smart strategy.
@@demef758 Yes, low quality cheap products have always had a market for poor people. But, didn't you describe his method as just randomly pulling out parts until it stopped working? I can't imagine a dumber method when trying to design an electronic product.
@@guitarista666 I don’t think Munoz was designing the product when he clipped wires until it failed. He would have been testing the necessity of certain design features. There is a distinction, but I highly doubt the anecdote of Muntz is true. I also think most companies design products as cheaply as they can get away with even if it is criminal. These kind of companies have a vested interested in keeping people poor because as you so eloquently say poor people are the market for low quality products.
Elon Musk eliminates excesses through iteration to make high quality products with laser sharp focus on the need of the customer that is embedded within growth mindset and safety framework.
@@BrandonJohnson-bx1ht Thanks for your reply. I don't know anything worthwhile about Munoz. My criticism was about the process of designing electronic circuits. I'm far from an expert, but I did take physics in college where you learn the physical principles involved, and, also, I took a course in TV servicing where we studied the circuits of the different sections. When you see how things really work, it is obvious how crucial even one inexpensive part can be. For example, capacitors are relatively inexpensive, but if one goes bad, then the TV could become unworkable. So, in trying to make a TV cheaper, it's not so much in eliminating parts, because they really don't load them up with non-essential components. What they do is use cheap, poorly made parts instead. Poor quality control also factors in where things are just thrown together in a rush. So, in general, it's a process of cutting corners wherever they can.
Awesome video. Thank you.
great presentation. thanks!
pre burners have been used in many diesels for years. having 39 engines is scary. Increases the probabilities of failure.
Also permits shutting down one or more engines without compromising the mission. This is why commercial airliners have more than one engine.
@@jamesbarnard9710 not really. Commercial airliners have more than one engine not only for being able to selectively shut them down if need be, it’s also do with the prohibitive expense of making larger and larger gas turbine engines, and being able to mount them in an aerodynamically stable position which can be hard with odd numbers of engines.
Awesome detailed explanation 👌
Great video. Informative. Thanks for sharing.
Very good 'article'! You kept it at an understandable level, which is nice for we older 'science nerds'. Next time continue on with the cooling aspects... it would not be too much. :-)
(I grew up in eyeshot of 'Canaveral', and all my classmates and I were recessed outside to watch John Glenn go up. I became enthralled that day, but I ended up following another path. My Dad worked for a subcorp of Rand, and was the project supervisor for more than one... government project. Those were the glory days of the 'space race'. He would be like a kid in a candy shop these days, his fingers twitching to do a close inspection all in appropriate garb for the 'white room'.
Thanks again!
I live just a few miles from Space X here in Central Texas. When they fire the engines, woha! Pure raw power. Every once in awhile one will fail and explode. It really gets your attention.
I find the Genius of Mr. Musk fascinating.
I lived in Huntsville Ala. when they were building the Space Shuttles and dealt with a few of the companies supplying parts and components of the shuttles. I would love to be able to tour Space X much like I did in Huntsville many times.
I am a metallurgist and I'm like a kid in a candy store around these technologies.

SpaceX's research and development capabilities is super impressive. When a company hires the most capable people it can and prioritizes efficiency and progress, this is the result.
This is so good, I need to watch it again.
How about a courtesy link to Everyday Astronaut since you're freebooting so much of his info and graphics?
What I'd really like to know is how the orbital launch platform stands the heat of a Starship launch without melting.
I guess they just cool it actively using something like liquified nitrogen?
likely it's water cooled.
By not really getting hit by the exhaust. The legs + the height = de facto giant 360 degree flame trench.
@@randombutrelevant1606 you’re going to regret this comment soon…
@@randombutrelevant1606 I see that you have not been paying attention to the space program.
Thanks for creating and sharing this cogent content. Maye the force
Excellent presentation of incredible content. There is not even one negative comment on this video.
This is not the first full flow engine. There have been other attempts. They are the first to move it to production
So then this is the first full flow engine?
One Russian, one American. Attempt is as good as any other word. Demo?
@@jamesconrad4268 full-flow staged-combustion-cycle rocket engines. It simplifies an engine in terms of parts needed (less mass).
@@michaelsmith2723 I believe the germans(?) had a working prototype and the russians may have as well. Definitely a demo at best.
First in production.... Successful Production ... Those of us in this aerospacec world knows that this has been attempted ..... Attempted isn't equivocal to successfully in production...
That's what makes Elon great he's not afraid to let us see him fail. But he also delivers on what he says.
@@randombutrelevant1606 sounds like you need counseling lol
Awesome explanation!!
This is well and good for the engine however a blown engine or one that explodes does little if the payload is damaged, regardless if they have another ready to go. A scientific payload is usually made as a one off, if it's research as rarely the money allotted for duplicates. Not downing the research (remarkable as it is) ,but would like to see the cost per weight ratio of payload. As this directly impacts payload development as well.
I've said it over and over again,,,, We need a Space Port .... Leaving these ships in space would improve the life span. Taking off from earth shakes the grap out of a ship. It put enormous G forces on the ship and reduces the life span. Also every time you take off and land, your using tons and tons of fuel to do that.. If you leave them at a Space Port, load them with fuel and equipment in space you'll will decrease there turn around time from landing on earth and taking off again. Faster, cheaper, much much more efficient. No ones listening!! what's the point of a comment area if no one reads the comments???????????????? I'm wasting my time
Good call - I agree
That is the plan, you should look up Nasas vision for the future of space missions to the moon and Mars
Idiot
Great video...explained very well.
It'll be cool to finally see this Raptor fly.
great content, thanks
