Reply to comment by Chevron7Nice in Russia may need to send a rescue mission to the International Space Station for 3 astronauts after a leak in their Soyuz capsule by A_Lazko
What about taking the damaged capsule to a point where it's safe to parachute down?

It's not about reaching a certain point it's about bleeding off all the excess speed.

Redbull guy was relatively stationary in space. The astronauts on the ISS is moving 7.7km per second around the earth. If they attempted to parachute back to earth, the astronauts will burn up. We’ll be lucky to even find a bit of their charred remains if at all.

They're in orbit, not just high up. The red bull guy was high up.
These people are much higher up AND going sideways so fast they keep missing the earth even though they're falling towards it.
It's slowing down from going sideways fast that creates a bunch of the heat. Even if they could stop, they also still have a really long way to fall and would still build up a ton of speed as they hit the atmosphere.
Turns out, space is hard.
