The temperature on Mars ranges from -125°F to -23°F or -87°C to -5°C Mars's average distance to the Sun is 1.52298629 AU's or 141,637,725 miles The polar ice caps of Mars are composed of frozen carbon dioxide. It takes 687 days for Mars to revolve around the Sun one time and it takes 24 hours and 37 minutes for it to rotate once The most recent space mission to explore Mars was the Phoenix Mars Lander. The Phoenix Mars Lander space probe landed on Mars on May 25, 2008 in the northern plains of Mars. The Phoneix was looking for ice water just below the surface near the North Pole of Mars. Water ice could give clues about the possibility of life on Mars. It used instruments to analyze the water ice. After a few months the Phoenix Mars Lander stopped working because the solar panels that made the electricity for it to run stoped making electricity because there was less daylight during the winter on Mars.
