How is it that we are able to enjoy live national or worldwide television and radio broadcasts? Make international telephone calls? Use high-speed Internet and nationwide paging services? Receive weather forecasts? Manage natural resource use? Respond to emergencies and disasters? Pay by credit card at a retail store? Satellite technology is the short answer. But how do those satellites make it into space? This is the function of commercial space transportation. Thirty years ago there was no commercial space transportation industry. By 2009, U.S. commercial space transportation and the services and industries it enables accounted for more than $208 billion in economic activity. Over one million people were employed as a result of these activities. This level is likely to grow in the future.
