Figure 9-17. About 30 small, low-relief domes located on the plains of Aino Planitia. Image (a), obtained at a 28.5-deg incidence angle (Cycle 1), discriminates brighter rough surfaces from darker smooth surfaces on the plains but does not provide sufficient topographic contrast to discriminate most of the domes. Corresponding image (b), obtained at a 15.6-deg incidence angle (Cycle 2), shows pronounced contrast between the domes and the plains but fails to reveal a significant contrast between the smooth and rough surfaces. Illumination is from the left.
