Visions of Mars

Visions of Mars offers a visual tour of the main geographic features of Mars as they have been recorded by twenty years of remote-sensing missions, ranging from the Viking orbiter/lander of the late 1970s through the Pathfinder orbiter/rover of the mid-1990s and up to the twin rover missions of today. The survey is driven by images, many of which have never been seen before, which introduce the reader to the plains, volcanoes, chasms, lake beds, and polar regions of the red planet. A final section summarizes the basic data that have been gathered about the planet, comparing Earth and Mars.
