I'm a recent Aerospace Engineering grad, from the University of Colorado, now a Test and Evaluation Engineer in the Aerospace industry. This channel is a place where I discuss science, occasionally build projects, and have fun making videos.
Does Starship Have Too Many Engines?
Today we're diving into the age-old question: "How many engines is too many?" From Saturn-V to SpaceX's Starship, we explore the evolution of rocket design and the surprising statistics behind engine reliability.
TL;DW: More engines mean more failures, but more engines also mean more redundancy. Through super-advanced analysis (random numbers in Matlab) I figure out where the cut-off is, and when adding more engines ends up being a net benefit. Spoiler: SpaceX is a competent engineering company... go figure.

The Biggest Rockets To Ever Fly
Просмотров 1,9 тыс.5 месяцев назад
Today we're looking at every single rocket to ever break the record for "the world's biggest rocket." This record can be broken into physical and performance-based metrics, I chose to use mass, height, payload mass, and thrust for this video. A special thanks to the following for collecting footage of many of these rockets: SpaceX: Starship SciNews: Sputnik 1 International Astronautical Federat...
Engineer Reveals the TRUTH behind SpaceX's Hot Stage Plans
Просмотров 6 тыс.7 месяцев назад
I decided to dig in and do the math to figure out what's going on with SpaceX's out-of-nowhere plan to hot-stage the world's biggest and most powerful rocket. Elon Musk recently tweeted that they would be reworking the next flight vehicles so the ship could fire its engines while it was still attached to the booster. Before we watch the next Starship launch live, let's break this down with a pr...

The story of CRS 7 and the 3rd failed mission to the Space Station within a year. This marks the end of the Long Year in Space. A SpaceX Falcon 9 attempted to launch the original Dragon spacecraft to the ISS but was destroyed around two minutes after launch, all due to a single, tiny, part. This video is blatantly inspired by Jon Bois (with the help of a BobbyBroccoli Tutorial) (0:00) - Recap (...

Today we're discussing the Mystery of the Progress M-27M Mission in Part 2 of my "The Long Year In Space" Series. Shortly after the Orb-3 mission was lost, The Russian Space Program tried to help pick up the slack with the their own Soyuz/Progress Launch but after a seemingly nominal launch, the spacecraft lost contact, leading to a race to figure out what went wrong, reconnect, and hopefully s...
When Old Soviet Rocket Parts Cost the US Millions

Today we're discussing the explosive Orbital ATK Antares Commercial Resupply mission, Orb-3. Orbital ATK (Now Northrop Grumman) re-used old Soviet Rocket engines on their space station resupply rocket but they let a manufacturing defect slip through the cracks and paid the price. This video is blatantly inspired by Jon Bois (with the help of a BobbyBroccoli Tutorial)

The Planes That Can Fly Themselves: Passive Stability
1)Посмотрите экспансию. Достаточно системы с постояннымиускорением. Вы сначала разгоняетесь до цели, на половины пути разворачиваете корабль и тормозите с тем же ускорением. Таким образом вектор тяги всегда направлены в одну сторону, прям как в лифте. Бах, у вас искусственная гравитация. Если хотите, чтобы было как на земле, то нужно ускоряться 9.8 км,/ч но это пока не достижимо. Зато можно постепенно кскоряться с помощью ионых двигателей
I actually made an entire video all about trying to use thrust gravity: ruclips.net/video/nRKNh-Gx9WA/видео.html
That’s pretty creative
Found your channel through this, if you're interested in making a video on that, I'd be very interested in seeing more about the feasibility of short radius centrifuges.
Why not just create a small artificial black hole in the middle?
Tether?! HELLLLLLLLLLLLLLL no. That's a massive disaster waiting to happen. Tethers are horrible if anything whatsoever goes wrong ever.
3 years later and 2 of that 3 billion space x received from the government hasnt done much. Space x still can't get star ship to explode. It won't get to the moon on the last billion, either. Yet another of Musks lies and failures.
Hey man, loved the video. I wanted to say that while it think it’s super important to make education content entertaining, and thus to do that one would need to make shorter content like you did by cutting out material (smart move) I would definitely love to see a video where you don’t hold back. For the boys ya know. So keep doing what you’re doing. It’s awesome. But you maybe one video this year do something more for yourself. A video where you get to just let loose and talk about all the wills and wacky things you think about. Cause I know I wish I could do that. But I don’t have an audience like you. I would love to see it.
Wtf is he talking about we went to the moon and they did it with out a y of that junk we jad people on the ISS for years and they had no problems when they came back
Subbed
I’d rather go to Titan
The accelerate/decelerate the small radius machine inside the ship, you would have to counterbalance the ship by using thrusters.
They couldn't stop the swelling of the eyes with the short radius centrifuge. Well yeah, duh. You are rising around the head so the head gets no "gravity" so the blood isn't pulled out of the head by the "gravity".
That was actually a control setup where they intentionally put the eyes at the center, they also extended the arm to put gravity on the eyes but it didn’t seem to help (at least in earth’s gravity) I wasn’t able to find footage of that unfortunately
[*orry, my * key no longer work* I have a PO* Dell laptop.] I'm really not into all the*e detail*. Ju*t *how u* an animation of two *tar*hip* tethered together and rotating no*e to no*e on the way to Mar*. End of video. And don't tell me you can't hook them together no*e to no*e. Innovate!!
Thank you I have a compulsion and need to try to understand the aspects of rotational Dynamics to create a stable artificial gravity that doesn't make you want to vomit or feel nauseous at all times it's very interesting and very much more complicated unless you're in a shit that's a Taurus I suppose although I find the concept of basically lobbing to tethered ships occasionally giving a boost to the ship that's on the Ford Mustang motion to tag the one behind so to speak yet rotating with it and Tethered to give boosts of velocity on occasion and I suppose it could be used to slow the velocity as well
Apparently Spacex tested tumbling starship in the last test flight. Rotating ship consumes fuel, no way to correct trajectory while spinning so it must be stopped and started again with thrusters
"That 2.98B will DEFINITELY speed up development" Whoops, nope, just went down the drain cuz Musk is a grifter
Heretics.
I think if you rewatch his video, he multiple times qualifies 'strongest shape' with provisions like 'least amount of material for strength' and such. He even fully explained graphene's weaknesses. That being said, both videos are quite informative.
It is not the strongest by weight, triangles may be twice as heavy (with the same thickness) but they much more than twice as strong
@@ConHathy I am referring to the argument he made specifically about honeycombs. For the amount of material, not weight, they create a strong home for honey storage and hatching new bees. I think he even mentioned that triangles were the strongest, but would require a lot more material to construct, and so for the amount of material in a pattern that takes up the least amount of wasted space, hexagons were ideal. I'm not saying you are wrong about anything. I'm just saying that he qualified his 'strongest 'shape with conditions. You seemed to imply that he declared hexagon the strongest shape period, and I didn't get that impression.
I think that we ought to at least send a spaceship up to do some real tests in space. The testing we have done on Earth is fighting against the real gravity of our planet, producing I think some skewing of the gravity data. In any case, if we were to provide a spinning environment for astronauts, they could perhaps retire to their beds for a good night's sleep in artificial gravity. This might make long voyages more tolerable because at least they could lie down as they sleep, maybe feeling more refreshed to work out the day's activities.
Lets take a moment to appreciate the quick remote camera work at arecibo tht gave us some once in a lifetime footage!
If we are waiting for Space X it is irrelevant because we will not be going anywhere.
we shouldnt go to mars.
soo 333 cents each, lol
Why cant elon just accept that the starship isn't a wonder ship, and that it would be easier for everyone to have a seperate craft for interplanetary voyages?
Skateboarders know all about the intermediate axis. Spinning the board around the other two axis are some of the first tricks you learn, flipping the board around the intermediate axis is called "The Impossible."
Would the three ship tether model be more stable if a boom was extended in both directions along the long axis of the central ship, changing the motion from a flip to a spin?
No, not if the booms came out of the nose/tail, but if they came out of the top/bottom it would. But again, why?
@@ConHathy More stability would be better than less stability. Unless, there is some dynamic method for maintaining stability. Modern jets are designed to be naturally unstable in flight, but have computerized flight controls that automatically stabilize the aircraft. Would a system of coaxial, counter-rotating tethers (similar to some Russian helicopter rotors) cancel out their natural instability?
6.33M subs vs 12K... Let's see who wins I think we already know who will win G R E Y
I dont understand why it's so hard. Just make a gravity generator smh.
"What if the teather breaks?" As if we can't build huge suspension bridges.
3 years on musk has missed every projected milestone, and starship can't even get into a lunar orbit, let alone to Mars. Waist of money giving that conman the contract.
Regarding using thrusters to spin up the tethered artificial gravity, if you use a rigid truss couldn't you instead do it with a reaction wheel? More generally, regarding the issues about stability can't many of these be handled with active control using reaction wheels?
The problem with reaction wheels is that they are inherently less mass efficient. Rocket exhaust moves at kilometers per second; to match that performance the wheel would have to be as wide as the entire vehicle and spin at kilometers per second as well, which is not practical at all
@@ConHathy Yah after a bit of consideration they just won't work for spinning up the system. But I'm not convinced they can't be used to actively control the system to maintain spin around an otherwise unstable axis.
It says ANSA on the chest.
If we are talking about what makes sense, a nuclear powered ship with a habitat ring.
Equivalence principal says that is real gravity
2:30 Stupid question: did you try your centrifuge experiments with the occupant in a fetal position?
No, but if you’re worried about the head being in the center that was actually a control setup where they intentionally put the eyes at the center, they also extended the centrifuge arm to put gravity on the eyes but it didn’t seem to help (at least in earth’s gravity) I wasn’t able to find footage of that unfortunately
@@ConHathy I was actually thinking the pressures on the body would be more equal than the head spinning at some fraction of gravity less(?) than feet are spinning.. With a short arm, do you keep a bucket handy? 🙃
@@LordDustinDeWynd ah, well it would be more even, but it’s also the equivalent of laying down because it’s pulling fluid to your back instead of your feet
@@ConHathy Indeed. Like I said, silly question. Thank you! (I'm disappointed we wont see Von Braun wheels...)
Howdy from Temple, Texas on May 11th, 2024!
Is the thumb musk or not? Only reason I clicked.
Begun, the polygon wars have.
Radio frequency with a lot of power. You can do a lot with it.
That short clip you showed of the guy in the centrifuge testing and saying it didn't reduce pressure in the eyes, I'm a layman and can tell you his head was basically at the center of the centrifuge meaning his heads had no simulated gravity effects, and they thought they were doing science? 🤦🏼♂️
That was actually a control setup where they intentionally put the eyes at the center, they also extended the arm to put gravity on the eyes but it didn’t seem to help (at least in earth’s gravity) I wasn’t able to find footage of that unfortunately
Why did the animation say ansa
This was fantastic. I'm glad you included the failures in history too and recognized their achievements even in failure. The N1 is one of spaceflights greatest what-ifs. I wish the world had seen a successful flight of that thing. That being said, the fact that they never got it right in four attempts really shows in contrast the greatness of the Saturn V. What's crazy is how different Artemis will be than the Apollo era. Looking back at Apollo, its the Saturn V that stands out as THE rocket. But, for Artemis, I imagine most people will not know what the SLS is, even after we land on the moon again. Instead, it'll be Starship and its booster that everyone will think of when they think of us going to the moon a second time. Even though it, as of now, will only land humans on the moon, not launch them there. Don't get me wrong, the SLS is great. I just think it just won't be the rocket that cements itself in the culture at large when it comes to the Artemis missions. And that's because of what this video shows: the biggest, most powerful rockets -- especially when successful, make the biggest impressions.
Centrifugal forces only work on a body with gravity such as the Earth. In space you would need EXPONENTIAL acceleration for it to work. otherwise you'd be spinning as fast as all around you but without any forces pulling you down on the floor. I am amazed this hasn't been pointed out more clearly so far.
hexagons made of triangles are the bestagons.
I lovethe idea of using a short radius centrifuge and being like, well we couldnt get the pressure in the eyes down. Like, no shit. The head is the center of rotation. Youve applied no force to the relevant area
That was actually a control setup where they intentionally put the eyes at the center, they also extended the arm to put gravity on the eyes but it didn’t seem to help (at least in earth’s gravity) I wasn’t able to find footage of that unfortunately
"Sir, this is still a Wendy's."
The biggest issue with producing artificial gravity is the energy required to maintain a constant acceleration.
Yes, unless you spin
Just accelerate at 9.8 m/s the whole way.
I actually made an entire video all about trying to use thrust gravity: ruclips.net/video/nRKNh-Gx9WA/видео.html
@@ConHathy awesome. I'll have to check it out
Yes but gravity isn’t what holds down onto this planet it’s air pressure, without air pressure we would just fly off into space. The Earths gravity is rather weak in reality and it is only a very small part of the equation. Centrifugal force is not going to create gravity and it doesn’t attract it just pushes out.
I remember when I was a kid I thought they just had rooms where they could somehow cancel gravity and that’s how astronauts trained.
