This map shows how much water ice is found near the North Pole on Mars. Purple and blue areas have lots of water ice. Yellow and red areas don't have much ice. Like Earth, Mars has a large polar ice cap. The purple and blue area near the center is the ice cap. Other areas have smaller amounts of ice buried a few inches beneath the soil. The Mars Odyssey Orbiter spacecraft collected this data in 2002.
