It might be a dead planet now, but it was probably a lush and active planet in its infancy. Mars is well know now as the dry, cold, red planet, but back in the early solar system everything was different. It was probably wet, probably had an atmosphere. So, what would a habitable, watery Mars look like? Perhaps it looked like this cloud-covered lake scene.
Take a look as the movie soars across the ancient Martian, flying over lakes (which may have existed on a young, thick-atmosphered Mars) and mountainous canyons, and watch as it slowly transforms into the red, rocky planet today.
