A striking infrared image of Mars' southern hemisphere, captured by the Mars Odyssey spacecraft's THEMIS instrument. False-color representation shows temperatures ranging from 0°C (red) to -120°C (purple). The image highlights the shrinking south polar ice cap (frozen CO2) and the temperature drop into the Martian night. A thin blue crescent at the top represents the Martian atmosphere. The image is a test of the THEMIS camera system, taken from 22,000 km altitude.
