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 ``modif","authors_text":"Eunice L. Lau, John D. Anderson, Kenneth L.
