Martian sunrise, artwork. Mars is a rocky desert world with no surface water. A Martian 'day' is known as a sol and lasts 24 hours and 39.5 minutes. The Martian atmosphere, less dense than Earth's, is mostly carbon dioxide. Surface temperatures are well below freezing. The gravity is about one third of that on Earth.
