In 2151, Matthew Ryan suggested that, if Enterprise NX-01 delivered a Nausicaan prisoner back to Nausicaa, the Nausicaans would probably award the returned captive with a medal. (ENT: "Fortunate Son")
Background information Edit
This planet was only mentioned in dialogue.
In the first draft script of "Fortunate Son", Admiral Forrest notified Captain Archer that Starfleet had filed a complaint with Nausicaa, regarding Nausicaan pirates operating in a particular sector of space, but that the Nausicaan government was, according to the Vulcans, in a constant mode of "transition."
According to Star Trek: Star Charts (pp. 60 & 64), Nausicaa was located in the Nausicaa system, in the Beta Quadrant. This system was a binary star system. Primary star was a Class M star with a magnitude of +3, which was ten times brighter than Sol. Secondary was a Class A star. In the mid-22nd century, this system was in non-aligned space. In the late 24th century, this system was located in or near Federation space.
