[Star Wars] how do mynocks fly once they are in the vacuum of space? Their wings would only work in an atmosphere.

The organs contained within the Mynocks wings can interact with gravity and magnetic fields. Kind of like a biological version of the repulsor lift that you can find in any speeder. This lets them move around in a vacuum by flapping. 

I suspect this is mostly just used to move from host/ship to host/ship they aren't going to be flapping between systems.
