Mars - Viking 1 Orbiter

Fractured northern plains, Mars

Mars
This Viking 1 Orbiter image shows a pattern of fractures commonly found in the northern plains of Mars. These polygons are approximately 5 to 10 km across, and are similar in appearance to certain terrestrial processes, but on a much larger scale. Note that the fracture crevasses are fairly wide with flat floors. North is at ~11:00 in this image, which is about 50 km wide. (Viking Orbiter 035A64)
