According to the Outer Space Treaty, the nation that launches a rocket into space must pay for any damages if it lands in another country. However, the Outer Space Treaty does not mandate payment for sex work or an onlyfans subscription.

This suggests that OP's mom will *not* be available to catch the rocket with her giant pussy, as there would be no way for her to make China pay for it.

$50 to whoever calls the city it hits closest to, if there’s any interest.

Thread consensus on the city if it’s a wide field of debris.

Ponta Delgada, the Azores

I guess it's an improvement over their previous launch where it fell over and flew sideways into a totally empty area of wilderness and exploded and killed zero people, there are no records of anyone ever living in that location.

18,000 miles per hour sounds so fast

If it hits near a coast or something it's just gonna gently caress up local fishing, right?

no, it won't be going that fast by the time it lands.

most of it will break up / burn up during reentry, and the little pieces left won't hit very hard because they'll be like chunks of sheet metal dropped from the sky. a piece of sheet metal doesn't fall all that hard, like a direct hit on a person would injure or kill. but if you're in your house it'd just gently caress up your roof a bit.



the engines survive all the way to the ground, they are heavier and more solid and hit way harder. if you happen to be under them, you get squished. but even then, it's way less destructive than a bomb.

I'm watching this thing move in real time over countries it's moving so fast. This is total bullshit. This type of rocket launch could kill thousands, and eventually will unless we outlaw them. gently caress this

no, it can't. it can only kill thousands of chinese people during launch, when it's full of like 500 tons of fuel and so can explode like a giant bomb.

an empty rocket is like a falling grain silo. very hard to imagine the scenario where that managed to kill a bunch of people eve if it does fall in a heavily populated area.

Oh

I honestly thought that because of its great speed it would be extremely powerful

It has great speed as it enters the atmosphere, and that's why things that re-enter from orbit burns up. But during that process it also slows down hella fast. Astronauts in space capsules* take 4-6 Gs of force during reentry. That is harder breaking than you have ever hit the breaks in your car by like 10 times. So they're slowing down by like 50 meters per second, every second, for a few minutes. That'll take you from 8000 m/s to under the speed of sound in 2 and a bit minutes.


And a big empty rocket will slow down even faster than an astronaut space capsule, in the same way that an empty beer can will fall a lot slower than a full bottle if you dropped it off a building. A rocket with no fuel is a giant empty beer can with some engines on the bottom.


* the shuttle did less than 2 G, because it could actually use the lift of being a plane to stay in the thinner upper atmosphere (thin = less friction, less force, less heat) for a lot longer than a capsule. landing in the shuttle was pretty comfy and more fun!

Spaceflight is risky, the point is to *not* have uncontrolled debris raining down from launches though. Most everyone except China is pretty on the ball on that.

TBQH the risk of hurting or killing anyone is pretty goddamn remote. Like, it's stupid that China is running so close to the edge of what their rocket can manage that they can't afford to put a system on it for the most bare-bones of re-entry control. Just "in the pacific" would be fine. But also I don't think it's an unconscionable risk.


The funny thing about the treaty that I mentioned before, it's the nation-state's responsibility to pay for damages even if it was some corporation that did the launch. So the US wouldn't let anyone like SpaceX do a launch this way, because then the US gov't would be on the hook for SpaceX's fuckups. So that's why everyone besides China is more on the ball. That and the potential diplomatic / prestige blowback.

tldr China don't care

Plus I imagine having a bomb on board would only dramatically increase the chances of something going horribly wrong.

Many rockets do have a self-destruct, but it's for when the rocket is launching if it goes out of control or something else is major wrong. Particularly solid rockets, because there's no way to turn those off other than blow them up. At that point you can use a very small explosive, due to the whole full of rocket fuel thing.

Not sure if China bothers though.

Spinz posted:

Why can't they simply have a remote controlled self destruct on board? (To control timing and/or make the debris smaller)

In space you don't want to explode anything because space debris is bad.

During reentry most of the rocket will break up into smaller pieces anyways. The metal walls of the fuel tanks are pretty thin & light, they're easy to rip apart by that type of force. That's why I said that most of the bits are basically sheet metal that's not super-dangerous.

The engines though are big solid things, which would be hard to blow up. And I imagine putting an explosive right next to a rocket engine would be pretty hairy.


But the biggest thing is, if they had the spare weight allowance to add a thorough self-destruct, they'd probably have the weight to add some tiny engines to control the thing and vaguely select where it comes back into the atmosphere. It doesn't take much nudge to do that in orbit. They're at the very limit of what their rocket can do.
