Download and read online ebook The Rock From Mars write by Kathy Sawyer. This book was released on 2006-02-14. The Rock From Mars available in PDF, EPUB and Kindle. In this riveting book, acclaimed journalist Kathy Sawyer reveals the deepest mysteries of space and some of the most disturbing truths on Earth. The Rock from Mars is the story of how two planets and the spheres of politics and science all collided at the end of the twentieth century. It began sixteen million years ago. An asteroid crashing into Mars sent fragments flying into space and, eons later, one was pulled by the Earth’s gravity onto an icy wilderness near the southern pole. There, in 1984, a geologist named Roberta Score spotted it, launching it on a roundabout path to fame and controversy. In its new home at NASA’s Johnson Space Center in Houston, the rock languished on a shelf for nine years, a victim of mistaken identity. Then, in 1993, the geochemist Donald “Duck” Mittlefehldt, unmasked the rock as a Martian meteorite. Before long, specialist Chris Romanek detected signs of once-living organisms on the meteorite. And the obscure rock became a rock star. But how did nine respected investigators come to make such startling claims about the rock that they triggered one of the most venomous scientific battles in modern memory? The narrative traces the steps that led to this risky move and follows the rippling impact on the scientists’ lives, the future of space exploration, the search for life on Mars, and the struggle to understand the origins of life on Earth. From the second the story broke in Science magazine in 1996, it spawned waves of excitement, envy, competitive zeal, and calculation. In academia, in government agencies, in laboratories around the world, and even in the Oval Office–where an inquisitive President Clinton had received the news in secret– players of all kinds plotted their next moves. Among them: David McKay, the dynamic geologist associated with the first moon landing, who labored to achieve at long last a second success; Bill Schopf of UCLA, a researcher determined to remain at the top of his field and the first to challenge McKay’s claims; Dan Goldin, the boss of NASA; and Dick Morris, the controversial presidential adviser who wanted to use the story for Clinton’s reelection and unfortunately made sure it ended up in the diary of a $200-an-hour call girl. Impeccably researched and thrillingly involving, Kathy Sawyer’s The Rock from Mars is an exemplary work of modern nonfiction, a vivid account of the all-too-human high-stakes drive to learn our true place in the cosmic scheme.

Mars is ingrained in our culture, from David Bowie's extra-terrestrial spiders to H.G. Wells's The War of the Worlds. The red planet has inspired hundreds of scientists, authors and filmmakers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, and astrologers found meaning in the planet's dance through the sky. Stargazers puzzled over Mars's unfamiliar properties; some claimed to see canals criss-crossing its surface, while images from early spacecraft showed startling faced and pyramids carved out of rusty rock. Did Martians exist? If so, were they intelligent, civilised beings? We now have a better understanding of Mars: its red hue, small moons, atmosphere (or lack of it), and mysterious past. Robots have trundled across the planet's surface, beaming back astonishing views of the alien landscape and seeking clues on how it has evolved. While little green Martians are now firmly the preserve of literature, evidence is growing that the now arid, frozen planet was once warmer, wetter, and possibly thronging with microbial life. Soon, we may set food on the planet. What challenges are involved, and how are we preparing for them? Is there a future for humanity on Mars? In 4th Rock from the Sun, Nicky Jenner reviews Mars in its entirety, exploring its nature, attributes, potential as a human colony and impact on 3rd Rock-culture - everything you need to know about the Red Planet.

The Space Studies Board of the National Research Council (NRC) serves as the primary adviser to the National Aeronautics and Space Administration (NASA) on planetary protection policy, the purpose of which is to preserve conditions for future biological and organic exploration of planets and other solar system objects and to protect Earth and its biosphere from potential extraterrestrial sources of contamination. In October 1995 the NRC received a letter from NASA requesting that the Space Studies Board examine and provide advice on planetary protection issues related to possible sample-return missions to near-Earth solar system bodies.

Often thought of as a volcanically dominated planet, the last several decades of Mars exploration have revealed with increasing clarity the role of sedimentary processes on the Red Planet. Data from recent orbiters have highlighted the role of sedimentary processes throughout the geologic evolution of Mars by providing evidence that such processes are preserved in a rock record that spans a period of over four billion years.
