Mars - Viking 1 Orbiter
Mars northern lowland fractured terrain
Viking 1 Orbiter image showing patterned ground in
the northern lowland plains of Mars. The individual
polygons bounded by the fractures can be up to 20 km
across, much larger than the 100 m sizes found in the
nearest terrestrial analogue, ice wedging in
periglacial regions. The image is 85 km across and
north is at ~1:30.
