NASA Mars Picture of the Day: Polygons and Craters
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-1203, 3 September 2005
 NASA/JPL/Malin Space Science Systems |
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows polygons enhanced by subliming seasonal frost in the martian south polar region. Polygons similar to these occur in frozen ground at high latitudes on Earth, suggesting that perhaps their presence on Mars is also a sign that there is or once was ice in the shallow subsurface. The circular features are degraded meteor impact craters. |
