Two years ago, following the detection of a strongly magnetized ancient crust on Mars, David J. Stevenson, professor of planetary science at the
California Institute of Technology (Caltech) published a theory that "Mars probably has a liquid, conductive outer core and might have a solid inner
core like Earth," in a review article in the journal Nature in 2001. However, if Mars had a core like earths then it would possess atleast a small
magnetic field which it does not. The lack of a modern day magnetic field on Mars has until recently been explained away by saying that the core of
Mars is completly solid.
According to the data returned by the Mars Global Surveyor, Viking 1 & 2, and the Mars Pathfinder scientists discovered that the core of Mars was
completly liquid. If the core is completely made of liquid then the only way to not produce a magnetic field is for the liquid not to be spinning.
This non spinning hot liquid would be greatly succeptable to the pull of the suns gravity. If this is true then just as the sun and moon act to create
high and low tides on earth the gravity of the sun pulling on a completely liquid core could cause high and low gravity tides by displacing mass to
one side of the planet.
