First up: Small Planetary Miner.

Folder: (when public) http://www.brickshelf.com/cgi-bin/gallery.cgi?f=443317
As is implied, this is a small planetary miner, but can travel to other nearby planets if necessary. It does not carry the materials out, only mines passages so workers and/or other machines can mine for a specific material.
Second: Planet Base

Folder: (when public) http://www.brickshelf.com/cgi-bin/gallery.cgi?f=443207
A small base that could exist on almost any planet; large, to accommodate any standard sized ship. Comes complete with laboratory in the corner. I built this on purpose with little detail because it is to be used in a brickfilm, and I didn't want too much detail to detract from the ships and story itself. Computers and other devices (any ideas?) will line the outer desk areas. The red and green studs are a futuristic design that demolecularizes matter and stores it the main computer, to be brought back when necessary; this allows for several ships to be present, but not seen.
Any ideas on how to improve on either of these designs would be greatly appreciated. Also if I am violating any of the rules (ex. picture size too big), please let me know.
Only the base folder is public so far, but here are a few thoughts:
