Imagine a day without space-based capabilities. What would happen to television? How would we forecast the weather? Global finance would grind to a halt. The stock markets would crash.Credit cards would be useless. Air travel would stop. These capabilities touch your daily life in ways that are unperceived. This course will examine the American and global dependency on these systems: Where are the satellites? How do they orbit? Do solar flares really cause problems on earth? How does GPS really work? How critical are satellites to national security and commerce? And in all of those movies, what is fact versus fiction?
