The simple answer is, we're going to Mars to search for life. We're following the water because on Earth where you find liquid water, organic material, and energy, you find life." u find life" Ed Weiler, NASA's Associate Administrator for Space Science Ear where you find liquid water, A century ago, the world was enthralled by Percival Lowell's vision of a Mars criss-crossed with the canals of a dying civilization distributing water from the polar caps. Later, Mars was thought to have been cold, dead and dry for eons, but striking new evidence suggests the planet was relatively warm and wet in geologically recent times, and that even now there are reserves of water frozen beneath the planet's surface. Today, robot spacecraft maneuver across the Martian surface while others orbit overhead seeking evidence of water, ice, and landing sites for further exploration. In recent years, the very possibilities for life have dramatically expanded as discoveries by biologists and oceanographers have revealed bizarre life forms where none would have been expected. And as the growing evidence that water flowed on Mars becomes indisputable, more spacecraft are soon to follow. This highly absorbing book relates how NASA and ESA have sought evidence of life on Mars. 'Follow the water' with noted science writer David Harland as he 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 accelerates with the Mars 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. Join the scientific adventure of a lifetime in this well-researched and thoroughly engrossing true account. 0aSCIENCE (GENERAL). 0aPLANETOLOGY. 0aASTRONOMY. 0aASTROPHYSICS. 0aASTROBIOLOGY.14aPOPULAR SCIENCE.24aPOPULAR SCIENCE IN ASTRONOMY.24aPLANETOLOGY.24aASTROBIOLOGY.24aEXTRATERRESTRIAL PHYSICS, SPACE SCIENCES.24aASTRONOMY.24aPOPULAR SCIENCE, GENERAL.2 aSpringerLink (Online service)0 tSpringer eBooks08iPrinted edition:z9780387260204 0aSpringer Praxis Books40uhttp://dx.doi.org/10.1007/978-0-387-29372-1zVer el texto completo en las instalaciones del CICY  2ddccER  c32890d32890  00102ddc40708LEaCICYbCICYcELd2025-07-10l0o520r2025-07-10 08:39:44w2025-07-10yER
