European Space Agency
23 reportsFor European Space Agency, the central questions concern navigation systems, while also considering human spaceflight partnerships and European launch infrastructure. One line of support comes from independent scientific analyses, and a separate test comes from mission documentation; together they clarify human spaceflight partnerships, but the result is bounded by the possibility that member-state decisions and development schedules can alter program scope.
