Book Description
On May 18, 1980, people all over the world watched with awe and horror as Mount St. Helens erupted. Fifty-seven people were killed and hundreds of square miles of what had been lush forests and wild rivers were to all appearances destroyed. Ecologists thought they would have to wait years, or even decades, for life to return to the mountain, but when forest scientist Jerry Franklin helicoptered into the blast area a couple of weeks after the eruption, he found small plants bursting through the ash and animals skittering over the ground. Stunned, he realized he and his colleagues had been thinking of the volcano in completely the wrong way. Rather than being a dead zone, the mountain was very much alive. Mount St. Helens has been surprising ecologists ever since, and in After the Blast Eric Wagner takes readers on a fascinating journey through the blast area and beyond. From fireweed to elk, the plants and animals Franklin saw would not just change how ecologists approached the eruption and its landscape, but also prompt them to think in new ways about how life responds in the face of seemingly total devastation.

Book Description
Brave astronauts, flaring rockets, and majestic launches are only one side of the story of spaceflight. Any mission to space depends on years--if not decades--of work by thousands of dedicated individuals on the ground. These are the people whose voices offer a friendly link to Earth in the void of space, whose hands maneuver rovers across the face of planets, and whose skills guide astronauts home. This book is a long-overdue history of three major centers that have managed important missions since the dawn of the space age. In Mission Control, Michael Johnson explores the famous Johnson Space Center in Houston, the Jet Propulsion Laboratory in Pasadena, and the European Space Operations Centre in Darmstadt, Germany--each a strategically designed micro-environment responsible for the operation of spacecraft and the safety of passengers. He explains the motivations behind the location of each center and their intricate design. He shows how the robotic spaceflight missions overseen in Pasadena and Darmstadt set these centers apart from Houston, and compares the tracking networks used for different types of spacecraft. Johnson argues that the type of spacecraft and the missions they controlled--not the nations they represented--defined how the centers developed, yet these centers ended up playing vital national roles as space technology became a battleground for international power struggles in the Cold War years and even after. The most visible part of a conflict that was just as real as the wars in Korea, Vietnam, and Afghanistan and caused great global anxiety, mission control centers have served as symbols of national security in the public eye and pivotal links in the history of modern technology.
