Astronomy: At Play in the Cosmos

A textbook that is not written like a textbook. Astronomy: At Play in the Cosmos brings popular science writing to a textbook. In every chapter, author Adam Frank―a co-writer of the NPR blog “13.7 Cosmos and Culture”―integrates two interviews with leading scientists, a fascinating second voice that drives the narrative while making astronomy feel immediate, relevant, and real for students, and still capturing science’s human nature.

Mars Wars: The Rise and Fall of the Space Exploration Initiative

Mars Wars: The Rise and Fall of the Space exploration Initiative investigates one of the most important chapters in the history of the space program. This is a story of bureaucratic infighting, personality clashes, cultural struggles, and a deeply flawed policy that ultimately doomed an effort to provide direction to a directionless agency by sending humans to the red planet. On the 20th anniversary of the first human landing on the ...

Electric Currents in Geospace and Beyond

Electric currents are fundamental to the structure and dynamics of space plasmas, including our own near-Earth space environment, or “geospace.”This volume takes an integrated approach to the subject of electric currents by incorporating their phenomenology and physics for many regions in one volume. It covers a broad range of topics from the pioneers of electric currents in outer space, to measurement and analysis techniques, and th...

Satellite Altimetry Over Oceans and Land Surfaces

Satellite remote sensing, in particular by radar altimetry, is a crucial technique for observations of the ocean surface and of many aspects of land surfaces, and of paramount importance for climate and environmental studies. This book provides a state-of-the-art overview of the satellite altimetry techniques and related missions, and reviews the most-up-to date applications to ocean dynamics and sea level. It also discusses related ...
