If you had to jump off of the space station with with your friends, and all you could bring with you were your spacesuits, parachutes for each of you, and you had a magic device that had enough oxygen (midwest.social)

for you to survive the journey. If you could somehow spray the oxygen to get you close enough to Earth to use the parachute and land safely, how would you do it?

Edit: and how much oxygen would it take to spray, would you need to use to oxygen to slow your decent? This is assuming the amount of oxygen you have would be the same amount required before you naturally deorbited like a junk satellite or something. So like, you don’t have any food so you wouldn’t make it that long, but that’s how much oxygen you magically have…. Could you make it out alive? And how?

Edit 2: one of you has a cool clipboard and space pen that astronauts have that you can do math with.

Edit 3: one of you is a stoner.

Edit 4: if the space station was in geosynchronous orbit, could an astronaut jump down off of it?

If you fall straight down so I guess that means straight down is still like 24000 mph or whatever the earth is rotating… but if you slow yourself down would you still burn up?

The only reason things burn up when they enter the atmosphere is because they're moving so fast that the friction from the air generates too much heat.

So yes, if you slow yourself down enough then you could just float down like a feather in the wind.

I have no idea how fast is too fast.

Minor nitpick, it's not friction, its compression. The air can't move out of your way fast enough, so you push it ahead of you, and as more air gets smooshed together, it gets hotter.

Fair enough.
