Need a few ideas for sample Space Stations

I'm trying to put together a few sample Space stations to include in the Administrator's section of the Knight Hawks book. So far I've thought of a few station types that might be common enough to include. These are:<br /><br />Orbital weapons platform: A small station which is simply a gun in space where a small crew can help defend a world against aggressors.<br /><br />Surveilence station: Another small station  that can be used by scientific and military teams to keep an eye on a variety of planets (developing worlds, plague planets, secret military bases, etc) <br /><br />and the classics: Construction space station, Agricultural, Recreation, Trade, and the mighty space fortress.<br /><br />Are there any other Space Station types that are common enough that should be included in the sample pack? <br />
