Earth’s neighbor Mars likely once had an environment that could have supported life. Now it has underground frozen water in many places. Spacecraft from Earth have visited Mars and taught us a lot about this dusty red planet. Featuring a center spread with fast facts, this book tells readers about the missions, the scientists who plan them, and more far-out facts about the fourth planet from the Sun.
