    This fascinating book traces what was a massive accomplishment right from the early launches through manned orbital spaceflights, detailing each step. Out of the battlefields of World War II came the gifted German engineers and designers who developed the V-2 rocket, which evolved into the powerful Saturn V booster that propelled men to the Moon. David Woods tells this exciting story, starting from America 's postwar astronautical research facilities. The techniques and procedures developed have been recognised as an example of human exploration at its greatest, demonstrating a peak of technological excellence.

    Genealogists and adoptees are using them and other DNA tests to identify ancestors, confirm relationships, and measure their ethnicity. Unfortunately, there are many similar sounding tests and some of them have different testing levels. So it’s easy to order the wrong test or pay too much. This Guide to DNA Testing provides an easy-to-understand introduction to the different test types, their strengths and limitations. Author and adoptee, Richard Hill, shared his personal success story in his book, "Finding Family: My Search for Roots and the Secrets in My DNA.” Now he boils down the basics of genetic genealogy into this concise summary. Learn which tests are right for you. Hyperlinks to specific tests and resources are included.

    Decades ago, astronauts brought back 850 pounds of rocks from their lunar journeys; the U.S. gave some away as “goodwill” gifts to the world’s nations. Over time, many of them disappeared, stolen or lost in the aftermath of political turmoil, and offered for millions on the black market. Gutheinz, first as a NASA investigator and then the leader of a intrepid group of students, has dedicated his life to getting them back. Author Joe Kloc tells a wild story of geopolitics, crime, science, and one man’s obsession with keeping the moon out of the wrong hands.

    Clarke was published in 1972 by Signet as an accompaniment to the novel 2001: A Space Odyssey.The book itself consists in part of behind-the-scenes notes from Clarke concerning scriptwriting (and rewriting), as well as production issues. The core of the book, however, is contained in excerpts from the proto-novel and an early screenplay that did not make it into the final version.Alternative settings for launch preparation, the EVA scene where astronaut Frank Poole is lost, and varying dialogues concerning the HAL 9000 unit are all featured in the book. Also included is the original short story The Sentinel on which 2001 is loosely based.

    de Camp has the trick of being able to show technology engaging in feats as full of derring-do as those of Hannibal's army. History as it should be told."--Isaac Asimov, The New York Times Book Review The Pyramids of Giza, the Parthenon of Greece, the Great Wall of China, the Colosseum of Rome. Today, we stand in awe before these wonders of the ancient world. They hold our history and the deepest secrets of our past in their hidden recesses.In The Ancient Engineers, L. Sprague de Camp delves into the heart of the mystery. He introduces us to the master builders who had the vision, the power, and the passion to reach for the clouds and touch the heavens. We share in some of the greatest technological triumphs of all time--triumphs of the human mind, imagination, and spirit.

    After decades of global primacy, NASA has ended the space-shuttle program, cutting off its access to space. No astronauts will be launched in an American craft, from American soil, until the 2020s, and NASA may soon find itself eclipsed by other countries’ space programs.With his signature wit and thought-provoking insights, Neil deGrasse Tyson—one of our foremost thinkers on all things space—illuminates the past, present, and future of space exploration and brilliantly reminds us why NASA matters now as much as ever. As Tyson reveals, exploring the space frontier can profoundly enrich many aspects of our daily lives, from education systems and the economy to national security and morale. For America to maintain its status as a global leader and a technological innovator, he explains, we must regain our enthusiasm and curiosity about what lies beyond our world.Provocative, humorous, and wonderfully readable, Space Chronicles represents the best of Tyson’s recent commentary, including a must-read prologue on NASA and partisan politics. Reflecting on topics that range from scientific literacy to space-travel missteps, Tyson gives us an urgent, clear-eyed, and ultimately inspiring vision for the future.

    Among them would be history makers, including the first American woman and the first African American in space. This assembly of astronauts would carry NASA through the most tumultuous years of the space shuttle program. Four would die on Challenger. USAF Colonel Mike Mullane was a member of this astronaut class, and Riding Rockets is his story -- told with a candor never before seen in an astronaut's memoir. Mullane strips the heroic veneer from the astronaut corps and paints them as they are -- human. His tales of arrested development among military flyboys working with feminist pioneers and post-doc scientists are sometimes bawdy, often hilarious, and always entertaining. Mullane vividly portrays every aspect of the astronaut experience -- from telling a female technician which urine-collection condom size is a fit; to walking along a Florida beach in a last, tearful goodbye with a spouse; to a wild, intoxicating, terrifying ride into space; to hearing "Taps" played over a friend's grave. Mullane is brutally honest in his criticism of a NASA leadership whose bungling would precipitate the Challenger disaster. Riding Rockets is a story of life in all its fateful uncertainty, of the impact of a family tragedy on a nine-year-old boy, of the revelatory effect of a machine called Sputnik, and of the life-steering powers of lust, love, and marriage. It is a story of the human experience that will resonate long after the call of "Wheel stop."
