Gale Crater on surface of Mars was once filled with liquid water for 10,000 to 10 million years, according to findings from the Mars Science Laboratory (MLS). A new study from Penn State scientists suggests dramatic climate cycles may have produced warm periods long enough to thaw the planet and create the water features on the surface today.
