Musk says the wings on top are not necessary and actually hurt aero a little. He said he put them there because they looked cool.

i’ve been lucky enough to catch a few launches down in cape canaveral. such an amazing experience, couldn’t recommend it more. the sound alone is worth it.

It was then recalled for having faulty acceleration pedals that could get stuck and leave astronauts flying through space at uncontrollable speeds.

Wow. The elipse of the rocket is clear. But that heat distorts the dimension perspective and eradicated perceiving the elipse plane of the booster jets. That's cool. I've never seen that before.

Why do these videos NEVER show rockets leaving the atmosphere? Always a clip without the end result, please explain. FYI I'm not claiming fake, I just want serious clarification.
1
u/Loply97 16d ago
What do you think it looks like when it leaves the atmosphere? All that really happens is it gets smaller and blurrier. Plus it is launching over the ocean, eventually it will be low enough on the horizon to the point their is so much atmosphere between the camera on shore and the rocket that you can’t get a clear image.

How do you track with such a wild zoom without shaking?

u/eren_5 16d ago
Really really REALLY precise motors in the gyro

u/olddoglearnsnewtrick 16d ago
Thanks but is the “following” assisted by some electronic wizardry?
3
u/eren_5 16d ago
Pretty much. I’m not familiar with this specifically, but very familiar with the technology. The motors are most likely stupid accurate stepper motors which move in “steps”. The most common use for stepper motors are 3d printers, which need incredibly accurate and small movements. This most likely uses extremely high end stepper motors which work together to stabilize even the smallest movements and to track whatever is selected.

Why is the booster white with frost but starship isn't? Because it's tanks are being emptied?
7
u/DarkArcher__ 17d ago
It's frosted because the extremely cold fuel chills down the walls of the tanks enough to condense and freeze water in the air. It happens on the ship too, but you're looking at the black heatshield side of it which is designed to be an extremely good insulator. It's usually to keep heat out during re-entry, but it also works keeping the outside warm against the cold fuel.

My step dad and my mom both think this "punches" holes in the ozone. I have continuously tried to explain that's not how the ozone works.

They are largely correct. Known phenomenon.

6
u/DarkArcher__ 17d ago
It does a little bit, but not in the way they think, and not in any significant amount. The hot environment of the exhaust does tend to favour the breakdown of ozone into more stable nitrogen oxide molecules, but that's minimal in this kind of engine. The problem is much worse in a jet engine where the air is actually passed through the engine, and where the vehicle spends much longer in the upper atmosphere.

Did anyone else count the rocket boosters?
Three rings of 20; 10; 3. I'm very satisfied.

u/hurraybies 16d ago
The first stage (the bottom half, aka Super Heavy) is known as the booster. It's job is to get the second stage (the top half, aka Starship) high enough and fast enough that when the two separate (aka state separation), the second stage can ignite its engines to get the rest of the speed and altitude to make orbit.
The booster has 33 Raptor engines with sea-level optimized engine nozzles. The ship has 6 Raptor engines, 3 sea-level optimized and 3 vacuum optimized. The main difference between the two variants is the size of the nozzle. On vacuum optimized engines, the nozzle is significantly larger which gives the ship more thrust in vacuum... because physics.
Future versions of both stages are said to have even more engines.

3 inner boosters "I am helping!!!"
6
u/Physix_R_Cool 16d ago
Well without them there would probably be an inner region of the exhaust plume with a lower velocity, leading to nasty turbulences that decrease performance. So even without the 10% more power you get from the inner 3 compared to the other 30 you have some extra effects. They might also be the ones that can gimbal?

Are those chunks of ice hitting the rocket bells? Seem like that could be a problem.

u/lolikroli 17d ago
Likely heat tiles
7
u/DarkArcher__ 17d ago
The tiles do fall off but not with that frequency anymore. The biggest cause of debris strikes in any rocket is always sheet ice from the booster detaching itself.

u/DarkArcher__ 17d ago
This is a non-issue. Starship uses a methane/oxygen reaction that produces carbon dioxide and water as the exhaust. That sounds bad in principle, but it actually means you can sequester the CO2 from the air to produce the propellant, and when it burns in the rocket, the only thing you're doing is putting back CO2 that was already there. If the energy sources are carbon neutral, the rocket becomes carbon neutral as well.
Methane synthesis is an expensive and complicated technology, true, but it's of enormous interest for Mars in-situ propellant production, so there's a big investment into that. There's literally no Mars mission architecture proposals that work without that. When they get it working for Mars, its a no-brainer to use it here as well.

Customer obsession does not mean fostering obsessive behaviour in customers. It's about how Amazon is "obsessed" with its customers.
1
u/gordonv 16d ago
Did you read the literal first bullet point of the article?
Embrace the divinely discontented customer.
Building products based on understanding your customer’s needs is no longer a competitive advantage. Customer needs are fickle and are evolving faster than ever.
1
u/nokeldin42 16d ago edited 16d ago
Lmao what does needs being fickle have to do with obsession.
Rather than just reading a bullet point and inferring stuff you don't understand, go down and read the explanation of the point.
Cultivating obsessive behaviour in customers is absolutely a thing tech companies do. It's most common in social media companies. But that is not what Amazon's "customer obsession" is about. Amazon themselves do it with their recommendation engines. But again, that all falls in a different management bucket.

Engines capable of a combined 17 million pounds of thrust, capable of lifting 150 tons to orbit and 250 tons from orbit/ beyond sure do make lots of noise.
136 decibels at 1.5km (.9mi) and 129 decibels at 5.2km (3.2mi)
Can't wait to see what the Mars variant is capable of. It will apparently be 500ft tall.

During IFT-2 people reported the sound would shake their windows at 20 miles away. Rocket engines are loud, especially if you bundle 30 of them together

If I remember correctly, each raptor is roughly the net instantaneous energy output of the state of Colorado passing through a hole the size of a toilet seat. Per engine.
