Our planet is constantly monitored by hundreds of space-borne
instruments. This book describes the technology of those instruments and
the sciences that provide useful information from them. It also
discusses the political implications of space-borne monitoring. From the
moment satellites were launched into orbit their ability to see what was
happening on a global scale was appreciated - and feared. This well
researched book strives to answer such diverse questions as: Are
satellites really a threat to individual privacy? How bad, really, is
climate change and global warming? Why can't we find Osama bin Laden?
Does the world have enough fresh water? 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. How the world
handles the knowledge gained from these Earth watchers will be critical
in the years to come, and Norris skillfully leads us through the issues
and possible paths we can take.
