First multi-year cumulation covers six years: 1965-70.
Governments around the world have had to deal with the UFO phenomenon for a good part of a century. How and why they did so is the subject of UFOs and Government, a history that for the first time tells the story from the perspective of the governments themselves. It's a perspective that reveals a great deal about what we citizens have seen, and puzzled over, from the "outside" for so many years. The story, which is unmasked by the governments' own documents, explains much that is new, or at least not commonly known, about the seriousness with which the military and intelligence communities approached the UFO problem internally. Those approaches were not taken lightly. In fact, they were con...

The Mars Curiosity Rover is the most sophisticated mobile laboratory ever deployed on a planet. For over seven years, scores of investigators have planned its daily route and activities, poring over the overwhelming images and data and revising our understanding of planetary surfaces, geology, and potential habitability. This book takes readers right down to the surface of Mars, chronicling Curiosity’s physical and scientific journey across the planet’s Earth-like, yet strikingly alien vistas. Through dozens of images and descriptive accounts of the surface, you will gain a deeper knowledge of the Martian landscape, from the floor of Gale Crater up to the cliffs of Mount Sharp. Presented at the end of each chapter are the results and revelations from the science team spearheading the mission. Like any cross-country road trip, the rover has hit some unexpected hitches along the way. The book describes the obstacles faced by the rover and its scientists over the years and the difficult decisions and careful experimentation it took to solve them.
This book is a collection of overview articles showing how space-based observations, combined with hydrological modeling, have considerably improved our knowledge of the continental water cycle and its sensitivity to climate change. Two main issues are highlighted: (1) the use in combination of space observations for monitoring water storage changes in river basins worldwide, and (2) the use of space data in hydrological modeling either through data assimilation or as external constraints. The water resources aspect is also addressed, as well as the impacts of direct anthropogenic forcing on land hydrology (e.g. ground water depletion, dam building on rivers, crop irrigation, changes in land...
