So...in the movie Gravity...

which is quite a flick...I found myself trying really hard not to scream "ARCH!!" at Sandra Bullock as she is tumbling through space after being knocked around by debris. And then I wondered....would body position make any difference with no atmosphere to work with??

Also...all space re-entry vehicles that have parachutes for landing assistance should have a user-reachable cutaway system from inside the capsule. Hello, spaceship makers?

If you're spinning in zero G, do the opposite of curling up into a ball. Take your arms and legs and spread them out as far as possible. This will slow down the rotation rate (as much as that's possible at all). It's called "conservation of angular momentum" and gymnasts and ice skaters use it exactly the opposite way to make themselves spin faster.

I'll have to remember that for my first zero G jump . That is, if I ever get off student status (she says, watching the October winds kick up and up...)
