Introduction
Interplanetary Colonization represents one of the largest technological and logistical challenges on the horizon for manned spaceflight.
USI's Modular Kolonization System (MKS) provides a huge array of new gameplay systems and supporting parts to support the experience of designing, building, and maintaining interplanetary colonies in Kerbal Space Progam.
For over three years, MKS has been the definitive Colonization mod for KSP, with continued refinement of the part
