This version of Outer Planets Mod has been built to work for KSP version 1.3.1 - 1.12.*.
The Outer Planets Mod is a mod that expands the outer edges of the Kerbol system to create something akin to the real Solar System's. It adds Kerbalized versions of Saturn, Uranus, Neptune and Pluto as well as several of these planets' moons. These faraway planets provide a challenge rarely encountered in Kerbal Space Program; you'll have to figure out new transfer windows, manage your power supply differently, provide your spacecraft with more Delta-V and be ready to travel years or even decades.
This mod is being developed and maintained by a group of collaborators, alongside and following the initial development of the mod creator, CaptRobau.
I strongly recommend users to download this mod and install it via CKAN, however, you can manually download and install Outer Planets Mod via SpaceDock and installation instructions are provided below.
Extract the GameData folder found in the downloadable .zip directly into your Kerbal Space Program install directory. If located correctly, the OPM and CTTP directories should be found at:
