Figure 1. Polar stereographic projection from 55oN latitude to the noth pole of Mars. (Left) Radial (vertical) component of the field, where blue represents the magnetic field direction into the planet and red represents the direction out of the planet. The spacecraft periapsis altitude was 170 km during this time. Data taken between 170 and 200 km have been organized in 100 km by 100 km bins, median sorted, and smoothed to yield the contours shown. (Right) Mars north polar region image topography corresponding to the left panel above included for reference (16). The north polar ice cap of Mars is the white, scalloped region visible in the center of the figure and is elevated above its surroundings by ~3 km.
