PDF-(BOOS)-The Sirens of Mars: Searching for Life on Another World

A young planetary scientist intimately details the search for life on Mars tracing our centuriesold obsession with this seemingly desolate planetMars was once similar to Earth but today there are no rivers no lakes no oceans Coated in red dust the terrain is bewilderingly empty And yet multiple spacecraft are circling Mars sweeping over Terra Sabaea Syrtis Major the dunes of Elysium and Mare Sirenumon the brink perhaps of a staggering find one that would inspire humankind as much as any discovery in the history of modern scienceIn this beautifully observed deeply personal book Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life transforming the planet from a distant point of light into a world of its ownJohnsons fascination with Mars began as a child in Kentucky turning over rocks with her father and looking at planets in the night sky She now conducts fieldwork in some of Earths most hostile environments such as the Dry Valleys of Antarctica and the salt flats of Western Australia developing methods for detecting life on other worlds Here with poetic precision she interlaces her own personal journeyas a female scientist and a motherwith tales of other seekers from Percival Lowell who was convinced that a utopian society existed on Mars to Audouin Dollfus who tried to carry out astronomical observations from a stratospheric balloon In the process she shows how the story of Mars is also a story about Earth This other world has been our mirror our foil a telltale reflection of our own anxieties and yearningsEmpathetic and evocative The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot while providing a vivid portrait of our quest to defy our isolation in the cosmos. 100 Mars is the only planet in our solar system to have frozen carbon dioxide snow it happens all year round. . in the north end.. . pictures from the mars curiosity shows landscapes made by bodies of water, rain and ancient rivers with the force of 10,000 Mississippi rivers..

The best-selling author of Stiff and Bonk explores the irresistibly strange universe of space travel and life without gravity. Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can’t walk for a year? have sex? smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible for the human body to survive a bailout at 17,000 miles per hour? To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations. As Mary Roach discovers, it’s possible to preview space without ever leaving Earth. From the space shuttle training toilet to a crash test of NASA’s new space capsule (cadaver filling in for astronaut), Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.
