This book relates how NASA and ESA have sought evidence of life on Mars. Science writer David Harland assembles and weighs the evidence in this timely and compelling book. It contains what you need to know behind today's, and possibly tomorrow's, headlines, including details of the Mariner, Viking, and Pathfinder missions and evolving theories of Martian geology and climate. It explains how the search continues with the Mars Express orbiter and Mars Exploration Rovers Spirit and Opportunity. Harland sets this within the broader perspective of the likely nature of life on Mars as compared to primitive life on Earth. Finally, he analyzes the implications of there being life on both planets.
