Re: OUT THE DOOR



A small magnet and loop of wire would work too.
The shorted loop of wire would act like a geerator
in the earths magnetic field and slow the rate
and the permanent magnet would eventually align
the suit with the earths magnetic field until
drag took over...  bob

I wonder if you could stop the spin of a SuitSat with just a CO2
cartridge?  Spray some gas out of a nozzle in the opposite
direction of the spin. You would have to know the mass of the
SuitSat and how far the nozzle is from the center of gravity.

The tricky part would be determining exactly what the spin is
that you have to correct. If you had two solar panels at right
angles to each other, you could probably determine the spin rate
by plotting the voltages. I'm sure that a way to measure spin has
already been worked out for previous satellites. I don't imagine
that anyone has tried to correct the spin of something as soft
and floppy as a space suit, though. 

It would be cool if you could correct the spin while it was still
within camera range. You would need a countdown timer with a
visable counter so that it was far enough away to be safe, yet
still close enough to see.

Stopping the spin will enable further experimentation by allowing
antennas and such to be pointed towards earth.

The CO2 cartridge would make a good teaching aid.  The ones for
BB guns have oil in them, but there are food-grade cartridges
that you can harmlessly spray in a classroom.
