   Did Mars lose it's magnetic field due to - for example - a cooling core -   
   less fluid - less movement = less gravitational field - and then lose   
   atmosphere, or did it never have much gravitational field? I am assuming   
   that volcanic activity on Mars is less than it was, therefore the planet   
   core is cooler, and therefore less fluid?
