Mars covered in water, computer artwork. This shows the planet in the future, when humans have terraformed it, leading to the formation of an atmosphere with clouds. The planet has also been colonised, and city lights are seen on the planet's night side. The Martian moons Phobos and Deimos can be seen transiting across the planet's disc, with Phobos at lower right and Deimos above it and closer to Mars. The Olympus Mons volcano is at upper left.
