1 The Origins of Martian Water: What We Can Learn from Meteorites
In 1877 telescopic observations of apparent lines on the Martian surface were interpreted by Giovanni Schiaparelli as resembling channels. Others, notably Percival Lowell, soon interpreted these as having been made by intelligent life. Today, the notion of canals and advanced forms of life have long since been dis-pelled by technological improvements in optical equipment and the advent of space missions. Yet the most recent images provided by Mars Global Surveyor (MGS) continue to show channels apparently cut by water. The question is no longer whether or not water is or was present, but how much there is, where did it originate and what does this mean for the possible evolution of life forms on the planet.
