Star Trek: Catan takes two well-known media properties and merges them into, well, into something that is 95% The Settlers of Catan glossed with Trek tropes and spiced with a Trek-themed version of a mini-expansion previously only available in German.
In Star Trek: Catan, players start the game with two small Outposts at the intersection of three planets, with each planet supplying resources based on the result of a dice roll. Players collect and trade these resources – dilithium, tritanium, food, oxygen and water – in order to build Starships that connect regions in the galaxy, establish more Outposts and Starbases (upgraded Outposts) at new intersection points in order to increase resource acquisition, and acquire Development Cards that provide Victory Points (VPs) or special abilities.
On a dice roll of 7, a Klingon ship swoops in to prevent resource production on one planet while taxing spacegoers who hold too many resources.
Star Trek: Catan differs from the basic Settlers in one aspect: a set of Support Cards formerly available only in German as Catan Scenarios: Helpers of Catan. Each Support Card features a special ability and one of Kirk, Spock, McCoy, Sulu, Scott, Uhura, Chekov, Chapel, Rand, or Sarek. Some special abilities make basic actions better, such as reducing the costs of Starbase upgrades or allowing the player to trade a resource of their choice at 2:1 for a turn, while others break rules, such as protecting the player from discarding on a 7 or producing a resource when the player rolls a number that wouldn't otherwise produce for them. Players get a specific Support Card during setup based on turn order, with later players getting generally more useful abilities to compensate for early player advantage. When a player uses a Support Card ability for the first time, they may trade it in for a Support Card of their choice or keep it for a second use, but they may only trade immediately after use.
These reference cards can be helpful to new players (or old players of regular Catan), so they can follow what planet color generates what resource.
Nothing elaborate, but the color - resource is not very intuitive, and having a card to quickly reference (rather than always looking at the rules) is handy for first-time players.
v1.1 - Minor rule correction (thanks JakeJekel37)
This file contains the rules and images necessary convert an extra copy of the game into two 5 or 6 player expansions.
If anyone finds any errors, either put it in the comments below or send me a PM.
Thanks to Martman for giving me the idea!
These cards were created by DraconicParagon for his "spacefarers of Catan" re theme of Settlers of Catan. I have adapted this expansion to work with ST Catan. The cards themselves are available here: http://draconicparagon.deviantart.com/gallery/41698385?offset=0

Apocalypse Catan By: John Dickey, Linda Dickey, Denise Miller and David T. Van Sweden
I used the original number chit and disaster tokens from here: http://vansweden.net/apoc-catan/

I used the following link to get the Black Hole Hex:
You will also need 3 warp trail tokens
The Lithium Mines of Rigel XII (Egessemine )
Adapted by: Martin Amdur
Based on: The Diamond mines by: Andrew (meepleeater) Which is based on the In the Jungle Variant by Klaus Teuber.
For the artwork I used this from DraconicParagon's DevaintART Gallery page:
http://tinyurl.com/spacefarers and selected the purple planet hex and used the PURPLEnese resource card.
Be sure to look at the tactical cards on the other project page as they make an expansion with little adaption.
I hope that by uploading this file, I can encourage others to make new (or adapt existing)variant / expansions for ST Catan.
