The trail to find Osama bin Laden was uncovered by human and satellite intelligence, and the raid that killed him was directed by a fleet of intelligence-collecting satellites over Pakistan. Even though we can't see them, satellites play a large role in reconnaissance and defense support. Students will learn about the rockets that launch satellites, how satellites are used, and how the military uses secret space planes and test vehicles that are ready to spy from space or engage in any possible space wars. Full color photos, fact boxes, and comprehensive coverage of the history of the US satellite program fill out this timely title.
