ABSTRACT
This chapter delves into the definitional aspects of spaceports, as well as their history and relevant space legislation using past and present US policies as the foundation of in-depth discussion. Definitions of spaceports are in flux, largely because requirements for launch are changing as spaceflight technology moves forward and flight profiles continue to change. Launch sites and spaceports have been around for some time, first emerging in the US in the 1940s when the federal government began building and operating launch ranges. The history of early US airport construction and financing can serve as a cautionary tale for spaceports now in use and in development. Airports, like spaceports, are on the ground but house the operations necessary to prepare for flight and landing, as well as navigation. The US addresses its policy goals for space activities and space transportation in two recent directives issued by the executive branch, the US National Space Policy and the US National Space Transportation Policy.
