This book was released on 2011. Exploring Mars available in PDF, EPUB and Kindle. The Red Planet has been a subject of fascination for humanity for thousands of years, becoming part of our folklore and popular culture. The most Earthlike of the planets in our solar system, Mars may have harbored some form of life in the past and may still possess an ecosystem in some underground refuge. The mysteries of this fourth planet from our Sun make it of central importance to NASA and its science goals for the twenty-first century.ÊÊ In the wake of the very public failures of the Mars Polar Lander and the Mars Climate Orbiter in 1999, NASA embarked on a complete reassessment of the Mars Program. Scott Hubbard was asked to lead this restructuring in 2000, becoming known as the "Mars Czar." His team's efforts resulted in a very successful decade-long series of missions--each building on the accomplishments of those before it--that adhered to the science adage "follow the water" when debating how to proceed. Hubbard's work created the Mars Odyssey mission, the twin rovers Spirit and Opportunity, the Mars Reconnaissance Orbiter, the Phoenix mission, and most recently the planned launch of the Mars Science Laboratory.Ê Now for the first time Scott Hubbard tells the complete story of how he fashioned this program, describing both the technical and political forces involved and bringing to life the national and international cast of characters engaged in this monumental endeavor.Ê Blending the exciting stories of the missions with the thrills of scientific discovery, Exploring Mars will intrigue anyone interested in the science, the engineering, or the policy of investigating other worlds.

Download and read online ebook Discovering Mars write by William Sheehan. This book was released on 2021-11-09. Discovering Mars available in PDF, EPUB and Kindle. For millenia humans have considered Mars the most fascinating planet in our solar system. We’ve watched this Earth-like world first with the naked eye, then using telescopes, and, most recently, through robotic orbiters and landers and rovers on the surface. Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we’ve learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes. Beginning with the Mariner and Viking missions of the 1960s and 1970s, space-based instruments and monitoring systems have flooded scientists with data on Mars’s meteorology and geology, and have even sought evidence of possible existence of life-forms on or beneath the surface. This knowledge has transformed our perception of the Red Planet and has provided clues for better understanding our own blue world. Discovering Mars vividly conveys the way our understanding of this other planet has grown from earliest times to the present. The story is epic in scope—an Iliad or Odyssey for our time, at least so far largely without the folly, greed, lust, and tragedy of those ancient stories. Instead, the narrative of our quest for the Red Planet has showcased some of our species’ most hopeful attributes: curiosity, cooperation, exploration, and the restless drive to understand our place in the larger universe. Sheehan and Bell have written an ambitious first draft of that narrative even as the latest chapters continue to be added both by researchers on Earth and our robotic emissaries on and around Mars, including the latest: the Perseverance rover and its Ingenuity helicopter drone, which set down in Mars’s Jezero Crater in February 2021.

Clancey. This book was released on 2012. Working on Mars available in PDF, EPUB and Kindle. Beginning in 2004, a team of geologists and other planetary scientists did field science in a dark room in Pasadena, exploring Mars from NASA's Jet Propulsion Laboratory (JPL) by means of the remotely operated Mars Exploration Rovers (MER). Clustered around monitors, living on Mars time, painstakingly plotting each movement of the rovers and their tools, sensors, and cameras, these scientists reported that they felt as if they were on Mars themselves, doing field science. The MER created a virtual experience of being on Mars. This book examines how the MER has changed the nature of planetary field science. NASA cast the rovers, Spirit and Opportunity, as "robotic geologists," and ascribed machine initiative to remotely controlled actions. Clancey argues that the actual explorers were not the rovers but the scientists, who imaginatively projected themselves into the body of the machine to conduct the first overland expedition of another planet. The author investigates how the design of the rover mission enables field science on Mars, explaining how the scientists and rover engineers manipulate the vehicle and why the programmable tools and analytic instruments work so well for them.
