I think it's relevant to life on Mars that plants don't grow at antartic temperatures, which are: > The highest temperature ever recorded at the Amundsen–Scott South Pole Station was −12.3 °C (9.9 °F) on Christmas Day, 2011, and the lowest was −82.8 °C (−117.0 °F) Mars: > A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about -100 degrees F (-73 C).
