"Visions of Mars" is filled with astounding images of Mars, most of them photographs taken by the Viking, Pathfinder, Spirit, and Opportunity lander missions, some by the Mars orbiters, and others created by computers based upon orbital laser data. Almost all of them are colored according to the best interpretation of what Mars would look like to the human eye (in general, the photographs are constructed from black-and-white images made with color filters, then layered together). We get to see the salmon-pink of the Martian sky and the coppery dust that covers the planet. Many of the orbital images show canyons that dwarf anything to be found on earth, Along the visual journey, the text explains the latest findings and thinking regarding the questions about water on Mars and the possibility of life there.
