Those who remember the Lego M-Tron subtheme of Lego Space will love this mod! Everyone else will still enjoy the retro and radical look of the M-Tron outfits, blocks, and furniture.
Starbound is the perfect game for Lego Space themed mods and M-Tron is the first of hopefully many to come.
For those unfamiliar with M-Tron: http://lego.wikia.com/wiki/M-Tron

The M-Tron were depicted as a civilian nomadic style of minifigs searching for the trans-neon green 1x1 rounds. The M-Tron were fairly peaceful except when encountering their opposite the Blacktron Future Generation theme as depicted in this 1991 catalog picture.
In this mod, the M-Tron mine aegisalt from various planets and sell it throughout the universe, as well as using it to craft some of their own objects.

Future plans for this mod:
-Recipes for all M-Tron items (for now, all items can either be crafted normally or printed at the pixel printing station)
-M-Tron ship replacement optional mod addons
-M-Tron settlers and crew
-M-Tron aegisalt mine planets and dungeons

This mod goes great with futuristic items!

Frackin' Universe is not absolutely required, but I highly recommend using it with this mod as the blocks and items go very well with M-Tron stuff.
