Olympus Mons on Mars

Mars
This image of the giant martian volcano Olympus Mons was taken over a 5 minute period at about 5:30 p.m. local time. Over the time the image was collected the altitude of MGS rose from 176 to 310 km. Olympus Mons is 25 km high and nearly 550 km across. The central caldera is 66 x 83 km in size. The bluish features to the right are water-ice clouds which tend to form around the volcano in the late afternoon. The color was synthesized using red and blue filter images. The image is centered at 23 N, 135 W, resolution of the image is about 1 km and north is up. (Mars Global Surveyor, MRPS85298)
