\subsection{Assumptions and Model of Mars} We are using a very simplified model of Mars for our calculations. We are approximating Mars as a spherically symmetric, Earth-like terrestrial planet with a metal-rich core and a liquid mantle. We are assuming net heat flow moves radially outwards because the core is the hottest portion of the planet. The moment of inertia of Mars ($I/MR^2$ = 0.366) indicates that the interior Mars is less differentiated than Earth.
