The 1995 Mars Opposition provided coverage of sub-Earth latitudes between 16 degrees N. and 22 degrees N. - a range of latitudes not covered by 3.5-cm radar during any previous Mars' closest approach. Fortuitously the Mars Pathfinder potential landing sites are constrained (by solar power, aerobraking, and communications engineering considerations) to be in Chryse Planitia, Isidis Planitia, and Amazonis Planitia, in areas which were sampled at high resolution during this Opposition. The preliminary prime landing site at the mouth of Ares Vallis in southeastern Chryse Planitia in particular was available at closest approach when the radar returns were strongest. The 100 x 200 km Ares Vallis landing ellipse covers an area that been rejected as a Viking Lander site in 1976, in part due to Goldstone CW radar echoes with low signal-to-noise (SNR). The Goldstone radar system at 3.5-cm is now 12 dB more sensitive than the 13-cm system in use at the time of the Viking landing site assessment, and thus definitive results on the potential problems of this site have been obtained. We present updated and integrated evaluations for landing hazards and radar imaging at the Ares Vallis site based on two types of radar observations: radar delay-Doppler profiles (ranging for short) and Continuous Wave (CW) radar spectra. Radar observations also cover Maja Vallis, Marte Vallis, Cerberus, and Isidis.
