Quoting the Wikipedia entry on Martian Climate:
QUOTE Differing values have been reported for the average temperature on Mars, with a common value being −55 °C. Surface temperatures have been estimated from the Viking Orbiter Infrared Thermal Mapper data; this gives extremes from a warmest of 27 °C to −143 °C at the winter polar caps. Actual temperature measurements from the Viking landers range from −17.2 °C to −107 °C. If that's true, then water could very possibly be just meters below the surface in some areas during daytime hours based on the lander estimates and could reside as liquid on the surface (if it was to get there) for extended periods according to the oribiter. For comparison, Antarctica's climate ranges from -80°C at the pole to 15 °C on the coasts. -------------------- |
