List of mods

Work in progress

This short list gathers the most important Addons of Kerbal Space Program.

Legend :

•  : Those mods are cell integrated into the Career Mode tech tree.

Building Parts Mainly adds some new stuf to build rockets and ships and more...
B9 Aerospace Pack Link is dead, awaiting to be transferred in CurseForge.		A parts collection for space planes. Very well designed and more realistic than the stock part.
KW Rocketry Link is dead, awaiting to be transferred in CurseForge. Forum Thread		A parts collection for Rockets. Another excellent designed part collection. More realistic, close to actual rockets
Home Link is dead, awaiting to be transferred in CurseForge.		Everything you need to build a good base on distant bodies
KAS – Kerbal Attachment System Link is dead, awaiting to be transferred in CurseForge.		Kas brings new a complete set of tools to build complex bases using yours kerbals during EVA. You can set up ressources pipes between parts of your base, adds elevators, cranes and many more.
Realism Those mods adds realism to the simulation making the gameplay harder than before.
RemoteTech. (incompatible with 0.23.5) Link is dead, awaiting to be transferred in CurseForge.		Your probe won't react anymore when far from Kerbal. You'll have to create a complete network of communication satellites to guide them in deep space. Adds delay (because of light speed limitation) to the control of distant probes, making navigation really harder with distant planets Forgives control of probes when behind planet (in the dark side of the mum for instance)
Ferram Aerospace Research		Adds a wide greater realism to the atmospheric fly. It is then really harder to make your ship fly correcly.
Tac Life Support		Manages cycle of life of kerbal people. Food, Water, Oxygen and Electricity is now need to maintains your astronauts alive during missing. A new difficult parameter to deal with.
Navigation and building tools
MechJeb.		A complete autopilot tools. Any of them are progressively dispatched in the Tech Tree. attitude pilots (Prograde, retrograde, node direction, vessel direction and so on) a complete computer for building (deltaV, TWR...) in the edit mode. gives various information for anything in the game (ships, orbit, target, planets.....) Fine tune and execute nodes Auto lander, docker, and lifter. and a futuristic probe.
Kerbal Engineer Redux		Nice designed information panel attached to the vessel. Gives information about each stage of the ship during building (DeltaV of each stage, TWR, ISP). and compute it realtively to bodies and their atmospherics parameters. Nice, simple and accurate.
Kerbal Alarm Clock		Adds alarms to various situation, stopping time warp. Very useful to avoid missing anything important in the game. In particular when you begin to have a huge set of probes and ships around the system.
Scientific Feature Gives scientific points in Career Mode and more.
ScanSat Terrain Mapping.		Creates Maps of celestial bodies, detects anomalies (easter eggs), surface slopes and Biomes. The map created from your satellites can be analyzed and then provide science points depending on your map coverage. The detected biomes helps landing your craft on interesting point of each body.
Kethane		One of the most incredible addon of Kerbal. Adds a brand new fueling system in the game. Kethane can be detected and drilled from any planet. It allows then to create fuel bases in moons as start points for long range exploration. It changes the whole game rules in an excellent way.
Misc Tools Must have tools
Toolbar		Gathers some others addons features in a single toolbar. Many addons use this.
Crew Manifest		Allows to transfer crew members between part of the ship. one of the most missing feature in current kerbal version.
KSP Mod Admin		Adding and removing Mods is quite easier with this tool.
Cheaters
HyperEdit		place your ship anywhere in space without the use of fuel. Useful for testing situations and creating missions, but a real spoiler for the career mode.

The criteria to be added in this list are simple :

• It adds important features to Kerbal. New game play....
• It corrects some missing stuff in the main game.
• There is no major bug...
• It's fun !

It is then totally subjective. Fell free to adds your favorites addons here.
