United Nations Space Authority

The United Nations Space Authority was a large department of the United Nations from 2080 to December 31, 2163, and was responsible for the many human colonies in the Sol system. Replacing the United Nations Office for Outer Space Affairs, the Space Authority vastly increased the capabilities of the United Nations with a space fleet and colonial security forces. Although the Authority proved successful in countering the major opposition groups of the 2160s, the internal structure of the UNSA was awkward in conducting war, and was ultimately redesigned into the United Nations Space Command.
