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.

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.

Yeah, absolutely.

PV equals NRT.

That's exact.

Do you remember the name of that law?

Close enough.

The ideal gas law.

Very ideal.

So they have to find a way to deal with all of this rise in temperature.

And the best way to do it is to use the atmosphere to slow you down.
