AI Thread Summary
Rescuing a stranded crew member on a spinning space station is theoretically possible, depending on the severity of the spin. A large mass attached at a distance could alter the moment of inertia, reducing angular velocity and allowing for stabilization. A rescue shuttle equipped with a long arm or portable attachment could maneuver to dock with the station once stability is achieved. This method could be adapted for various spin axes. Historical examples, such as the Space Shuttle capturing a spinning satellite, support the feasibility of such operations.

If a crew member were stranded on space station, due to spin, would he be rescuable? For example if an extended part bent or broke, putting the ship into a spin or tumble. If it were a one axis spin, perhaps a large mass, attached at a distance would change moment of inertia sufficient to reduce the angular velocity, so that gyroscopes could recover. Thus if the rescue shuttle had a very long arm or portable attachment, it could rotate with space station transiently at a distance, until stability allows for automatic Russian or American docking. For a tumble, such procedure would seem repeatable for all 3 axes.

Beam him up, Scotty.
 
It of course depends on the severity of the spin, but the Space Shuttle did once capture a satellite spinning at 0.5 degrees per second:

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
