Editing Saturn (section)

===Historical=== 
During the early 21st century the first manned Earth-Saturn probe was launched, under the command of NASA's Colonel Shaun Geoffrey Christopher. (TOS: "Tomorrow is Yesterday") Accompanying Christopher were astronauts Fontana and O'Herlihy. (ENT: "First Flight") 

According to Spaceflight Chronology, this mission was conducted on the UNSS Lewis and Clark. Signs of past mining activity was discovered from the second and fourth moons of Saturn, first proof of the existence of extraterrestrial intelligent life. This last detail and "One Small Step" would put the mission after 2032. 
By the early 24th century a shuttle route had been established "from Jupiter to Saturn and back, once a day, every day," know as "the Jovian Run." Both Edward Jellico and Geordi La Forge used to pilot shuttles on this route early in their Starfleet careers. (TNG: "Chain of Command, Part II") 

In early 2367 the invading Borg cube passed Saturn on its way towards Earth. (TNG: "The Best of Both Worlds, Part II") 

In 2368, the Nova Squadron was set to perform a demonstration near Saturn that was be transmitted to that year's Starfleet Academy graduation ceremonies. (TNG: "The First Duty") 

[edit] Political 
Saturn and its moons are within Federation territory. 

While it is unclear if Saturn itself is inhabited or not, a reference made, in TOS: "Mudd's Women", to Saturnius harem girls might suggest that it somehow is. The necessity of a daily shuttle run (r.f. "Chain of Command, Part II", would also seem to support this possibility.
