Mars feels both familiar and different. It has seasons, polar ice, dust storms, and a day length that is not too far from Earth’s, yet it is much colder and drier.
Researchers study Mars to learn about ancient water, climate change on planets, and the possibility that tiny life may have existed there long ago.
Mars has volcanoes, canyons, craters, dusty plains, and ice near its poles. Its thin atmosphere cannot hold heat the way Earth’s atmosphere can.
