Abstract
Doppler radio-tracking data have provided detailed measurements for a martian gravity map extending from 30°S to 65°N in latitude and through 360° of longitude. The feature resolution is approximately 500 kilometers, revealing a huge anomaly associated with Olympus Mons, a mascon in Isidis Planitia, and other anomalies correlated with volcanic structure. Olympus Mons has been modeled with a 600-kilometer surface disk having a mass of 8.7 x 1021gramsKeywords
