In order, you have to move that fast to
in order to not fall back to earth that's the basics of the like force of gravity so you have to achieve these velocities you do that with these big rockets and you get moving but then when you're most of that acceleration is done after you've gotten above most of the atmosphere so you know the it the atmosphere is thickest near the surface
So at the surface, the rocket, when it's launching, is not moving tens of thousands of kilometers an hour.
They don't have to deal with that atmosphere drag as much.
But when you achieve orbital velocities, you're above the atmosphere.
And now you're moving at a speed so fast that you can't do that in the atmosphere.
So now they're on their way back and they have to find a way to shed tens.
I think they're moving at like 40,000 kilometers an hour.
which is insane.
And they have to get to zero kilometers an hour without having any serious injury or destruction of a spacecraft or anything like that.
That's right.
Even more.
It gets it can get to so that the surface of the sun is about 5000 Celsius and it gets hotter than that.
So what happens is the spacecraft, when it starts entering the atmosphere, it's not about friction.
It's actually about compression.
So the spacecraft actually squishes the air in front of it really, really quickly.
And when you squish a gas, when you make its volume smaller, you shoot its temperature up like crazy.
And if you do it really fast, then you shock it really, really hot.
Did I get that right?
Yeah, nailed it.
