ABSTRACT
Space launch and reentry operations have an effect on ground and airborne activities as objects transit from Earth to space. The effects of commercial space launch and reentry operations on commercial aviation and other airspace users should be considered in spaceport site selection and design. The foundational purpose of air traffic control (ATC) is to prevent collisions between aircraft. There are well-established roles and responsibilities between pilot and controller to ensure this objective is achieved. At its core, ATC is a safety service; however, safety and efficiency are not divorced partners. There are several terms that are often not well understood because the plain language definitions may differ from their technical application. Terms like uncontrolled or nonregulatory airspace often create confusion. Understanding how airspace is managed instead of how air traffic is controlled helps build an understanding of the role of the air navigation service provider and the relationship to space operations.
