Payback for today? ,I think we might be missing something else that happened
In a magnetic field with gravity pulling inward a sphere is created not a disc, you would need more pressure on the top and bottom than the sides, doesn't happen in space, earth is not totally round it's slightly oval which makes it an oblique spheroid, our eyes just can't register the slight difference, to us it looks round like a ball, sorry rover, have to play frisbee another day.
Forget the size ,wasn't real big but noticeable
