Satellites in the High Country by Jason Mark Pdf

In Satellites in the High Country, journalist and adventurer Jason Mark travels beyond the bright lights and certainties of our cities to seek wildness wherever it survives. In California's Point Reyes National Seashore, a battle over oyster farming and designated wilderness pits former allies against one another, as locals wonder whether wilderness should be untouched, farmed, or something in between. In Washington's Cascade Mountains, a modern-day wild woman and her students learn to tan hides and start fires without matches, attempting to connect with a primal past out of reach for the rest of society. And in Colorado's High Country, dark skies and clear air reveal a breathtaking expanse of stars, flawed only by the arc of a satellite passing--beauty interrupted by the traffic of a million conversations. These expeditions to the edges of civilization's grid show us that, although our notions of pristine nature may be shattering, the mystery of the wild still exists--and in fact, it is more crucial than ever.

High Throughput Satellites by Hector Fenech Pdf

This exciting new book discusses the motivation for the evolution of a new breed of High Throughput Satellites (HTS) that have emerged from traditional communications satellites. It explores the commercial sectors and technical context that have shaped HTS. The historical underpinnings of HTS are provided to highlight the requirements that dimension these satellites. A survey of operational GEO HTS systems is also included. Readers will understand the technical, operational and commercial context of HTS systems, as well as the performance of the current HTS system. This initial breed of satellites was limited to geostationary satellites, but it is quickly projecting into low earth orbit (LEO) constellations, often referred to as mega-constellations. The industrial and operational facets of LEO constellations are challenging. The characteristics of GEO and LEO systems are presented to understand the differences between the two systems. The book also explores the evolution of the current HTS payload architectures, as well as theoretical methodology is presented for the capacity estimation for both the FORWARD link and RETURN link, which can be used for preliminary HTS dimensioning and can be adapted to practical scenarios.

Dog of the Decade by Deborah Thompson Pdf

What do dogs mean in America? How do Americans make meaning through their dogs? The United States has long expressed its cultural unconscious through canine iconography. Through our dogs, we figure out what we're thinking and who we are, representing by proxy the things that we don't quite want to recognize in ourselves. Often, it's a specific breed or type of dog that serves as an informal cultural mascot, embodying an era's needs, fears, desires, longings, aspirations, repressions, and hopeless contradictions. Combining cultural studies with personal narrative, this book creates a playful, speculative reading of American culture through its canine self-representations. Looking at seven different breeds or types over the last seven decades, readers will go on an intellectual dog walk through some of the mazes of American cultural mythology.

Beloved Beasts: Fighting for Life in an Age of Extinction by Michelle Nijhuis Pdf

Winner of the Sierra Club's 2021 Rachel Carson Award One of Chicago Tribune's Ten Best Books of 2021 Named a Top Ten Best Science Book of 2021 by Booklist and Smithsonian Magazine "At once thoughtful and thought-provoking,” Beloved Beasts tells the story of the modern conservation movement through the lives and ideas of the people who built it, making “a crucial addition to the literature of our troubled time" (Elizabeth Kolbert, author of The Sixth Extinction). In the late nineteenth century, humans came at long last to a devastating realization: their rapidly industrializing and globalizing societies were driving scores of animal species to extinction. In Beloved Beasts, acclaimed science journalist Michelle Nijhuis traces the history of the movement to protect and conserve other forms of life. From early battles to save charismatic species such as the American bison and bald eagle to today’s global effort to defend life on a larger scale, Nijhuis’s “spirited and engaging” account documents “the changes of heart that changed history” (Dan Cryer, Boston Globe). With “urgency, passion, and wit” (Michael Berry, Christian Science Monitor), she describes the vital role of scientists and activists such as Aldo Leopold and Rachel Carson, reveals the origins of vital organizations like the Audubon Society and the World Wildlife Fund, explores current efforts to protect species such as the whooping crane and the black rhinoceros, and confronts the darker side of modern conservation, long shadowed by racism and colonialism. As the destruction of other species continues and the effects of climate change wreak havoc on our world, Beloved Beasts charts the ways conservation is becoming a movement for the protection of all species including our own.
