MOC Views of Martian Solar Eclipses (Original NASA/MGS/MSSS - Natural Color Frame)

This picture shows wide angle red (left), blue (middle) and color composite (right) views of the shadow of Phobos (elliptical feature at center of each frame) as it was cast upon western Xanthe Terra on August 26, 1999, at about 2 p.m. local time on Mars. The image covers an area about 250 Km (155 miles) across and is illuminated from the left. The meandering Nanedi Valles is visible in the lower right corner of the scene. Note the dark spots on three crater floors - these appear dark in the red camera image (left) but are barely distingished in the blue image (middle), while the shadow is dark in both images. The spots on the crater floors are probably small fields of dark sand dunes.
