Book Description
Access -- no single word better describes the primary concern of the exploration and development of space. Every participant in space activities -- civil, military, scientific, or commercial -- needs affordable, reliable, frequent, and flexible access to space. To Reach the High Frontier details the histories of the various space access vehicles developed in the United States since the birth of the space age in 1957. Each case study has been written by a specialist knowledgeable about the vehicle described and places each system in the larger context of the history of spaceflight. The technical challenge of reaching space with chemical rockets, the high costs associated with space launch, the long lead times necessary for scheduling flights, and the poor reliability of the rockets themselves show launch vehicles to be the space program's most difficult challenge.

Book Description
Have you ever wanted to live in space? To see the majesty of Earth from orbit, to play in a zero-gravity wonderland, and be on the cutting edge of civilization? Such a place may be built sooner than you think. New scientific research, new technological developments, and new social trends are all combining to make settlements in space easier than ever to build. Not long ago Al Globus, a space settlement expert and software engineering contractor at NASA Ames Research Center, made two key scientific discoveries: - that equatorial low earth orbit (ELEO) has vastly lower radiation than most other places in space, - and that humans can adapt to rotating space structures faster than many people thought possible. These discoveries, combined with a fast-developing rocket industry and burgeoning financial and political support for space development, mean that humanity may be on the brink of a building boom in orbit. In a few decades space settlements could vastly improve life on Earth by developing new technologies, unlocking trillions of dollars of raw materials and energy in space, and opening up a new frontier for all humankind. In this fast-paced book learn how your future in space is closer than you think!

Book Description
The classic case for why government must support science—with a new essay by physicist and former congressman Rush Holt on what democracy needs from science today Science, the Endless Frontier is recognized as the landmark argument for the essential role of science in society and government’s responsibility to support scientific endeavors. First issued when Vannevar Bush was the director of the US Office of Scientific Research and Development during the Second World War, this classic remains vital in making the case that scientific progress is necessary to a nation’s health, security, and prosperity. Bush’s vision set the course for US science policy for more than half a century, building the world’s most productive scientific enterprise. Today, amid a changing funding landscape and challenges to science’s very credibility, Science, the Endless Frontier resonates as a powerful reminder that scientific progress and public well-being alike depend on the successful symbiosis between science and government. This timely new edition presents this iconic text alongside a new companion essay from scientist and former congressman Rush Holt, who offers a brief introduction and consideration of what society needs most from science now. Reflecting on the report’s legacy and relevance along with its limitations, Holt contends that the public’s ability to cope with today’s issues—such as public health, the changing climate and environment, and challenging technologies in modern society—requires a more capacious understanding of what science can contribute. Holt considers how scientists should think of their obligation to society and what the public should demand from science, and he calls for a renewed understanding of science’s value for democracy and society at large. A touchstone for concerned citizens, scientists, and policymakers, Science, the Endless Frontier endures as a passionate articulation of the power and potential of science.

Book Description
Detroit’s industrial health has long been crucial to the American economy. Today’s troubles notwithstanding, Detroit has experienced multiple periods of prosperity, particularly in the second half of the eighteenth century, when the city was the center of the thriving fur trade. Its proximity to the West as well as its access to the Great Lakes and the St. Lawrence River positioned this new metropolis at the intersection of the fur-rich frontier and the Atlantic trade routes. In Frontier Seaport, Catherine Cangany details this seldom-discussed chapter of Detroit’s history. She argues that by the time of the American Revolution, Detroit functioned much like a coastal town as a result of the prosperous fur trade, serving as a critical link in a commercial chain that stretched all the way to Russia and China—thus opening Detroit’s shores for eastern merchants and other transplants. This influx of newcomers brought its own transatlantic networks and fed residents’ desires for popular culture and manufactured merchandise. Detroit began to be both a frontier town and seaport city—a mixed identity, Cangany argues, that hindered it from becoming a thoroughly “American” metropolis.
