Space station

A space station is a platform or facility built for use such as habitation, research or defense in a planetary orbit or deep space. The term can also be applied to mobile facilities.

Overview
The first human space station in the modern era was the Russian Salyut 1, launched on April 19, 1971. Following the success of the Salyut-series in the 1980s, the Russians launched the Mir on 20 February 1986. The Mir was the first modular space station capable of supporting multiple unit modules, thus allowing greater flexibility in operation, as well as removing the need for a single immensely powerful launch vehicle.

In 1998, five space agencies came together and initiated the International Space Station programme, a global effort to construct a space station for research purposes in a microgravity and space environment as well as serving as a landing platform for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.

More space stations were constructed across Sol with the advent of interplanetary colonization in the late 21st century, followed by other star systems in humanity's subsequent interstellar era. By the 26th century, space stations had come to fill a broad range of roles as starship construction and docking facilities, heavily-armed defensive outposts, fleet support, even as colony habitats, in addition to their original primary role as science facilities.

Space stations in the Covenant
The Covenant was a chiefly space-based civilization; the hegemony's military was heavily distributed across vast space fleets, and its capital city High Charity was a mobile station almost constantly on the move. This stands in contrast to humanity's practice of concentrating their cultural, political and military centers on planets.

List of known Covenant space stations

 * High Charity - the Covenant's mobile capitol and holy city.
 * Unyielding Hierophant - a Covenant mobile fleet command center.
 * Station of Constant Sustenance - a resupply facility in the fringes of the Covenant's empire.
 * Ap'ot Port - a Kig-Yar spaceport in the Y'Deio system.
 * Ranarum Orbital Platform - a Sangheili space station and docking facility orbiting their homeworld Sanghelios. It houses the Aanrar Shipyard.

Forerunner space stations
The Forerunners constructed their most notable space installations on a planetary scale, and many of them are more aptly described as megastructures than space stations. The Halo rings, the Arks, the shield worlds and the Capital are examples of such installations. Nonetheless, there are some which fall within the more conventional definition of a space station.


 * Deep-Space Anomaly 0198 - a small station in orbit around Threshold in the Soell system.
