dc.description.abstract The year 1996 will mark the initiation of a number of new space missions to the planet Mars from which we expect to obtain a rich set of data, including spacecraft radio tracking data. Anticipating these events, we have analyzed the feasibility of testing a violation of the strong equivalence principle (SEP) with Earth-Mars ranging. Using analytic and numerical methods, we have demonstrated that ranging data can provide a useful estimate of the SEP parameter $\eta$. Two estimates of the predicted accuracy are quoted, one based on conventional covariance analysis, and the other based on ``modified worst case'' analysis, which assumes that systematic errors dominate the experiment. If future Mars missions provide ranging measurements with an accuracy of $\sigma$ meters, after ten years of ranging the expected accuracy for the parameter $\eta$ will be of order $\sigma_\eta\approx (1-12)\times 10^{-4}\sigma $. In addition, these ranging measurements will provide a significantly improved determination of the mass of the Jupiter system, independent of the test of the {\small SEP} polarization effect.
