This map layer shows how and to what extent states are making use of space.
To describe the degree of space engagement by states, we distinguish ten direct and indirect ways of using space (astronauts, human space flight, human planetary exploration, commercial operators, space objects, rocket launches, launchers, space agency membership, space exploration and space station). The map shows how many of each type of use are recorded for each country. It can also be useful to know about membership of multinational space organizations, so this information is listed as a separate category. After all, certain types of use are only available to some countries through their membership of multinational space organizations because, domestically, they do not have the necessary resources and capabilities.
The term “objects” refers here to all space objects, although these are mainly satellites, registered with the United Nations Office for Outer Space Affairs (UNOOSA). A space probe in operation is classified here as a case of space exploration.
