Except when released at rest with respect to the satellites centre of 
mass the test masses will both drift towards the satellites centre of mass.
The outermost test mass will have too slow an orbital speed to remain at 
the position it was released and the innermost test mass will have too 
large an orbital speed to remain at the position at which it was released.
