About this image

Simultaneous THEMIS infrared and visible images near the south polar cap in late summer. The black areas in the infrared image are near -125 degrees C and correspond to solid CO2 ice. The purple regions are areas of exposed water ice at a temperature near -95 degrees C. The warmest (red) areas are classic 'dark lanes' of frost-free soil at a temperature near -55 degrees C. The right panel shows the same infrared image with a THEMIS visible image superimposed. The infrared image is approximately 32 km wide.
