Abstract: In view of the forthcoming Mars missions with seismological and geodetic experiments on board, the sensitivity of Mars' normal modes to interior structure changes is examined. The emphasis is put on the Chandler Wobble (CW) and the Free Core Nutation (FCN), as both can play an important role in the nutations and rides of Mars. The FCN, especially, is found to have a large potential for inferring properties of the interior structure of Mars. If observed, it will prove that Mars contains a liquid core, and information about the core radius and density jump at the Core-Mantle Boundary (CMB) can be obtained. Spheroidal oscillation modes of Mars are also shown to provide a powerful and additional constraint on the Martian interior. (C) 2000 Elsevier Science B.V. All rights reserved.
