Spaceport [SEP] Introduction
A spaceport or cosmodrome is a site for launching (or receiving) spacecraft, by analogy to seaport for ships or airport for aircraft. The word "spaceport", and even more so "cosmodrome", has traditionally been used for sites capable of launching spacecraft into orbit around Earth or on interplanetary trajectories. However, rocket launch sites for purely sub-orbital flights are sometimes called spaceports, as in recent years new and proposed sites for suborbital human flights have been frequently referred to or named 'spaceports'. Space stations and proposed future bases on the moon are sometimes called spaceports, in particular if intended as a base for further journeys.
