A Southern California man who killed his wife propped up her body on a sofa, told their children she was drunk and had them open Christmas presents in front of her body, a prosecutor told jurors at his murder trial.
Its amazing to think that to get from there to the ground down below, you almost have to burn up in a fire ball.
If you could go slow, that wouldn't happen at all.
why can't you go slow?
Well, gravity.
isn't gravity less the higher you go? Skydivers don't burn up coming down and don't they have gravity?
It's the friction entering the atmosphere. Going from no friction to immediate friction. The upper atmosphere has friction, just less. So the effects are not the same as going from none to some. The issue is weight of fuel. They carry only what they need into space, meaning they don't have controlled reentry into atmospheres, they just free fall with gravity. But if you could just sort of creep in, that wouldn't be an issue. But the amount of fuel you would have to carry up to do that, is quite a bit.
I mean if you fall just above the atmosphere, as a person, your weight being so small, might not burn.

sky divers have no fuel at all.
They aren’t traveling at 17,000 mph either.
They also aren't going from no friction to friction. They are in constant friction.

how much fuel would it take to fire a small rocket to slow an astronaut from 17,000 mph to 0 mph without killing him?

A lot more than they are willing to spend to take up with them.
