Water at Martian south pole
17 March 2004
| Map of the Mars south pole, as derived from OMEGA infrared spectral images, showing the bright polar cap, rich in carbon dioxide (light pink), surrounded by water-rich ice, free of carbon dioxide (green to blue).

| | | | | Global map of water ice at the south pole of Mars. Mapping of the water ice; blue areas show deep absorption, i.e. areas with water ice, red areas are ice-free. The water ice areas extend far beyond the carbon dioxide rich bright cap, along its scarps up to isolated units tens of kilometres wide.

The south pole is where the OMEGA instrument made its significant discovery, with the steep slopes known as ‘scarps’ made almost entirely of water ice, falling away from the polar cap to the surrounding plains, and the permafrost fields that stretch for tens of kilometres away from the scarps.
