Space transportation is the movement of, or means of moving objects, such as communications and observation satellites, to, from, or in space. Commercial space transportation is carried out by vehicles owned and operated by private companies or organisations. Today, the U.S. is among several countries that offer commercial launch services and comprise at least 25 percent of all launches world-wide. This book focuses on recent trends in the commercial space launch industry, challenges that the FAA faces in overseeing the industry, and emerging issues that will affect the federal role.
