Watching Earth from Space

Our planet is constantly monitored by hundreds of space-borne instruments. This book describes the technology of those instruments and the sciences they provide with useful data. It also discusses the political implications of space-borne monitoring.

Explains the power, limitations, and possible threats posed by satellite imagery Recounts the politics, economics, and science driving the growth of imaging from space Shows how the effects of global warming and climate change are revealed by imaging satellites Includes supplementary material: sn.pub/extras

Auteur
Watching Earth from Space derives from the author's unique experience of being part of the team that developed Europe's first and Japan's latest generations of weather satellites, of using satellite images to monitor the UK potato and sugar beet crops, and helping to define the use of satellites to monitor global change and prevent nuclear war. Pat Norris's direct access to politicians, civil servants, technologists, and both military and civilian users of space images worldwide has also proved essential to the accuracy of the story told in this book. This book is the natural successor to Pat Norris's book on the origins of spy satellites: Spies in the Sky (Springer-Praxis, 2008), which told the story of the first military satellites to monitor the Earth.

• Are satellites a threat to individual privacy? - How bad is climate change and global warming? - Why can we not find Osama bin Laden? - Does the world have enough fresh water? Watching Earth from Space gives you the answers to these and many other burning questions of the day. This is the story of how our planet is being monitored by hundreds of space-borne instruments for both military and peaceful reasons. It highlights the technical challenges of those instruments and describes the agencies that gather useful information from them. But as well as all the essential monitoring performed by satellites - such as mapping natural or man-made disasters, agricultural performances, weather, and climate change to name a few - there is a growing swell of public opinion that they are being used by governments to erode personal privacy and freedom. This book looks at the possible conflict between public good and market forces, and the future development of new systems to deal with new needs.

Résumé
The military side of the story is linked to the big security issues that we face, such as terrorism and civil wars. The civilian side of the story involves numerous successful collaborations in weather forecasting, navigation, communications, and other such "peaceful" uses of satellite surveillance.
