Nearly five billion years ago, Earth and Mars were born together as planetary siblings orbiting a young, emerging Sun. Yet today, one planet is water rich and life bearing, while the other is seemingly cold, dry, and forbidding.

Earth and Mars is a fusion of art and science, a blend of images and essays celebrating the successful creation of our life-sustaining planet and the beauty and mystery of Mars. Through images of terrestrial landscapes and photographs selected from recent NASA and European Space Agency missions to Mars, Earth and Mars reveals the profound beauty resulting from the action of volcanism, wind, and water. The accompanying text provides a context for appreciating the role of these elemental forces in shaping the surfaces of each planet, as well as the divergent evolutionary paths that led to an Earth that is teeming with life, and Mars that is seemingly lifeless.

Earth and Mars inspires reflection on the extraordinarily delicate balance of forces that has resulted in our good fortune: to be alive and sentient on a bountiful blue world.
