Hans Mark – författare

A comprehensive resource on the past, present, and future of space technologyResearchers in optics, materials processing, and telecommunications require a reference that can provide a quick study of a number of basic topics in space science. The two-volume Encyclopedia of Space Science and Technology represents an ambitious collection of the underlying physical principles of rockets, satellites, and space stations; what is known by astronomers about the sun, planets, galaxy, and universe; and the effect of the space environment on human and other biological systems. The Encyclopedia covers a variety of fundamental topics, including: A state-of-the-art summary of the engineering involved in launching a rocket or satelliteThe control systems involved on the ground, in orbit, or in deep spaceManufacturing in space from planetary and other resourcesPhysicists, astronomers, engineers, and materials and computer scientists, as well as professionals in the aircraft, telecommunication, satellite, optical, and computer industries and the government agencies, will find the Encyclopedia to be an indispensable resource.

By any measure, Hans Mark was a warrior of the Cold War. Born in Mannheim, Germany, in 1929, he spent his early childhood in Vienna before escaping the Nazi Anschluss in 1938 and eventually emigrating to the United States, settling in New York. He graduated from high school in 1947, went west to attend the University of California, Berkeley, and later earned a PhD in physics from MIT. His work in nuclear engineering soon set him on a path that would be shaped by aeronautics, space exploration, and national defense. It was through advanced technology that Mark believed the United States could win the Cold War.In An Anxious Peace, Mark recounts in detail his life as a twentieth-century ""rocket man."" Here is the inside story of one who—in a career spanning more than six decades—was on the technological front line, from long-range bombers to the space shuttle. Along the way, Mark reveals many never-before-told stories from life at NASA and more.Readers will revel in learning the background behind the decision to place a plaque on Pioneer 10, a space probe that the NASA Ames Research Center designed to fly past the asteroid belt, Jupiter, and Saturn to collect data and images. Mark tells how he, Carl Sagan, and NASA insider John Naugle kept secret the addition of the now iconic 6x9-inch aluminum ""message from humanity"" until the probe had been launched. To this day Mark is pushing for a manned mission to Mars. One thing is sure: Hans Mark has left a major impact on academic and scientific communities that will be felt for decades to come.

Writing even in overview of more than a half-century of professional life of a giant of twentieth century science and technology such as Edward Teller is a daunting task. We ask in advance the reader's pardon for passing over quickly or omitting entirely aspects of Teller's life and work which may seem of major significance but which we, due to differences of perspective or knowledge, speak too little or not at all. We refer those interested in greater depth to the excellent biography by Stanley Blumberg and Gwen Owens, The Life and Times of Edward Teller, and we have (with his permission) printed Professor Eugene Wigner's An Appreciation On the 60th Birthday of Edward Teller immediately after this foreword, so that the reader may consider the perspective of one of Teller's most illustrious contemporaries more than two decades ago. Edward Teller was born in Budapest, Hungary on January 15,1908. While his childhood was spent in the twilight of the Victorian age and its abrupt conclusion in the Great War and his youth in its especially turbulent after­ math in central Europe, he doesn't bear visible scars from it.
