Artist's impression of a base on Phobos, the inner moon of Mars. The painting shows a time when Mars has been partially terraformed (rendered like Earth). A network of lights from human colonies can be seen on the dark side of the planet. Water fills Mars' giant Valles Marineris canyon to make it a real 'Martian canal'. At lower right, on Phobos, the angled 'railway' is one of the mass- drivers which launched dark, carbonaceous material onto Mars' polar caps so that the planet absorbed more radiation & released frozen water. (The idea of terraforming Mars was seriously proposed in the early 1980s by James Lovelock & Michael Allaby in their book The Greening of Mars.)
