Kerbal Space Program Mods (1.1 edition)

Updated 2016-04-22 13:34 (GMT -4)

Version 1.1 of KSP has just been released, so I will be updating this page with mod descriptions and compatibility notes as I work my way through the list.

Please note, version 1.1 is a full engine upgrade, (from Unity 4 to Unity 5). Squad overhauled a lot of the code, so expect many mods to require significant updates, or changes in functionality. Some mods may be discontinued.

64-bit is now fully supported, which means that texture-heavy mods will no longer cause the game to crash on load (as long as you have enough RAM), so memory management mods should no longer be required… unless you have very little RAM and a lot of mods. 😉

Boilerplate from previous versions of the mod list:

If you’re new to KSP, or completely unfamiliar, it is a simulation game, where you take the role of director for the little green man version of NASA/ESA/Roscosmos/etc. (I wrote a preview/review of it a while back)

One of the reasons for its success is its massive mod community, which has taken the stock game and added a tremendous amount of depth in the way of new ship components, graphical overhauls, sounds, functionality (life support, flight model re-write, mining/resource gathering, etc), and other content.


KSP 1.1 has an API which allows save games to be brought in from version 1.0.5, as well as documentation to allow mods to bring their data forward as well. Until a mod has been updated and confirmed to keep data intact, be sure to keep backups of your saves in case of space kraken.

Below is my list of what I feel are the best and most useful mods, but also those that I feel add fun touches to the game.

Bug Fixes

Some enterprising souls take it upon themselves to fix bugs until Squad’s next official release. Here are some particularly handy ones I’m trying out currently.

Phoenix Industries Stock Bug Fix Modules: 1.0.5a.4: Fixes for a variety of major and minor issues for 1.05.  [Not yet updated] 

Core Modules

Alternate Resource Panel: Excellent replacement for the built-in resource panel, highly configurable. Can be set to activate when using the stock resource button. [Not yet updated+]

AVC: Automatic Version Checking for KSP. For the mods that support it, this is a great plugin for keeping up to date on the latest versions of your favorite mods. [WORKING+]

Blizzy’s Toolbar: 1.7.11: Toolbar required for additional functionality with some mods. [WORKING, pre-release]

Chatterer: 0.9.8: Actual functionality added to the game: zero. Amount of ambiance? Significant. This mod inserts Kerbalized dialogue and communication sound effects to the game. It even ties in with RemoteTech. [WORKING+]

Community Tech Tree: 2.4: Community-edited tech tree re-work to incorporate modders’ work in a unified system. [WORKING]

Contracts Window+: 6.2: The existing mod window is a bit of a nightmare. CW+ allows you to get a much better view of what you’re working on and filter out the unnecessary data. [WORKING+]

Deadly Reentry: 7.4.0: Just what it sounds like. Reentry becomes far more perilous. Ablative heat shields included. [Pre-release]

Ferram Aerospace Research: 0.14.6: Enhanced flight model and aerodynamics tools. Makes atmospheric flight much more realistic and enjoyable.  [Not yet updated+]

Kerbal Alarm Clock: Alarm clock GUI with lots of trigger options. Essential for running parallel missions. [Provisional version available+]

Kerbal Engineer Redux: Really handy mod for surfacing all the hidden details that you need for planning and executing your launches. Especially useful in the VAB/Hangar. (Be sure to middle-click on things) [WORKING+]

Kerbal Joint Reinforcement: 3.1.4: Performs a number of adjustments to make joints stronger, as well as stabilize physics on load or when leaving warp.  [Not yet updated+]

MechJeb: 2.5.7: Enhanced flight information, plus maneuver planning and autopilot functionality. [WORKING]
MechJeb FAR extension: Modifications to MJ to work with FAR’s flight model. [Not yet updated]

Module Manager: 2.6.22: This is a single DLL that goes in the GameData folder root that is required for many other mods to function. It allows modders to non-destructively add attributes to stock or other developers’ spacecraft part files. [WORKING]

MonkeyWrench: 0.1.5: Disclaimer: This is the mod I’m working on. 🙂 Contains a number of tweaks using KAS and TweakScale, and modifies the utility of a number of other systems. Hit the releases link on the project home page to see the OmniRCS. [On hold+] (The 1.1 update, and a lot of of other mod improvements have changed the focus of this mod, so I’m waiting to see before I continue work)
