The seismometer on Lander 1 failed to operate, the only significant instrumental failure on either spacecraft. Although the seismometer on Lander 2 worked as anticipated, its ability to detect Marsquakes was greatly compromised because it was mounted on the upper deck of the spacecraft. Most of the recorded vibrations were induced by wind or by operation of spacecraft components. The unusual graphic effects are reminiscent of a science fiction illustrator's vision of what a spacecraft on an alien planet should look like. Particularly well displayed in figures 74 and 76 is a view of the same drift complex shown in figures 66 and 67, although this view is taken with the other camera.
Different lighting accentuates different detail in both nearfield and farfield.
Almost certainly this is the upraised rim of an impact crater, about 500 m in diameter and 2.5 km distant. Part of the far side of the central cavity can be discerned toward the left, particularly in figure 79. This same crater has been identified in Orbiter photographs and has been used to locate the Lander position. Refer to figure 204. Also visible beyond the crater rim is a ridge 8 to 10 km distant.
