During much of the Cold War, America's first line of defense was in outer space: a network of secret satellites that could provide instant warning of an enemy missile launch. The presence of these infrared sensors orbiting 22,000 miles above the earth discouraged a Soviet first strike and stabilized international relations between the superpowers, and they now play a crucial role in monitoring the missile programs of China, India, and other emerging nuclear powers. Jeffrey Richelson has written the first comprehensive history of this vital program, tracing its evolution from the late 1950s to the present. He puts Defense Support Program operations in the context of world events - from Russian missile programs to the Gulf War - and explains how DSP's infrared sensors are used to detect meteorites, monitor forest fires, and even gather industrial intelligence by "seeing" the lights of steel mills.

The fascinating history and unnerving future of high-tech aerial surveillance, from its secret military origins to its growing use on American citizens Eyes in the Sky is the authoritative account of how the Pentagon secretly developed a godlike surveillance system for monitoring America's enemies overseas, and how it is now being used to watch us in our own backyards. Whereas a regular aerial camera can only capture a small patch of ground at any given time, this system—and its most powerful iteration, Gorgon Stare—allow operators to track thousands of moving targets at once, both forwards and backwards in time, across whole city-sized areas. When fused with big-data analysis techniques, this network can be used to watch everything simultaneously, and perhaps even predict attacks before they happen. In battle, Gorgon Stare and other systems like it have saved countless lives, but when this technology is deployed over American cities—as it already has been, extensively and largely in secret—it has the potential to become the most nightmarishly powerful visual surveillance system ever built. While it may well solve serious crimes and even help ease the traffic along your morning commute, it could also enable far more sinister and dangerous intrusions into our lives. This is closed-circuit television on steroids. Facebook in the heavens. Drawing on extensive access within the Pentagon and in the companies and government labs that developed these devices, Eyes in the Sky reveals how a top-secret team of mad scientists brought Gorgon Stare into existence, how it has come to pose an unprecedented threat to our privacy and freedom, and how we might still capitalize on its great promise while avoiding its many perils.

They are on the cutting edge of technology--the top-secret, billion-dollar instruments of super-power espionage. They are spy satellites--the means by which the super-pwers keep tabs on each other in the deep black of space. Excellent . . . Highly recommended --Booklist.

This "compellingly hard-hitting" bestseller from a Pulitzer Prize finalist gives readers the complete untold story of the top-secret military base for the first time (New York Times). It is the most famous military installation in the world. And it doesn't exist. Located a mere seventy-five miles outside of Las Vegas in Nevada's desert, the base has never been acknowledged by the U.S. government — but Area 51 has captivated imaginations for decades. Myths and hypotheses about Area 51 have long abounded, thanks to the intense secrecy enveloping it. Some claim it is home to aliens, underground tunnel systems, and nuclear facilities. Others believe that the lunar landing itself was filmed there. The prevalence of these rumors stems from the fact that no credible insider has ever divulged the truth about his time inside the base. Until now. Annie Jacobsen had exclusive access to nineteen men who served the base proudly and secretly for decades and are now aged 75-92, and unprecedented access to fifty-five additional military and intelligence personnel, scientists, pilots, and engineers linked to the secret base, thirty-two of whom lived and worked there for extended periods. In Area 51, Jacobsen shows us what has really gone on in the Nevada desert, from testing nuclear weapons to building super-secret, supersonic jets to pursuing the War on Terror. This is the first book based on interviews with eye witnesses to Area 51 history, which makes it the seminal work on the subject. Filled with formerly classified information that has never been accurately decoded for the public, Area 51 weaves the mysterious activities of the top-secret base into a gripping narrative, showing that facts are often more fantastic than fiction, especially when the distinction is almost impossible to make.
