Thunder Aerospace Corporation Life Support (TACLS)

Many Kerbal lives were bravely sacrificed to bring you the latest in biological needs.

Having problems with this mod (or any others)?
Read the [Official] How To Get Support and my Help page. Posts or problem reports without log files will now be ignored.

TAC Life Support is under new management in conjunction with the Realism Overhaul team! We are glad for the opportunity to keep this great mod alive. We are also very grateful to @TaranisElsu for creating TAC Life Support. Our hats are off to him.
@danfarnsy had been maintaining TAC LS for the past 6 months and we thank him for doing so. But he has been having problems with finding the time to keep up the maintanence, so I have agreed to take over maintanence of this fine mod. Danfarnsy will still be part of the team and be contributing to this mod as time permits him to do so. Thread for the past 6 months here.


What is TACLS?

TAC Life Support is a mod which adds food, water, oxygen, and electric charge as requirements for survival in space. Go without support for too long, and your Kerbals die a non-fiery death! Included are parts with storage for food, water, oxygen, waste products, as well as some recyclers for oxygen and water. It does not include support for growing food, but there are many mods which play well with TACLS to provide this functionality. It also integrates well into Realism Overhaul!



  • Kerbals require resources to survive, whether in a vessel or on EVA: Food, Water, Oxygen, Electricity (for air quality and climate control)
  • Resources are needed all the time, even when flying another vessel, or sitting at the Space Center or Tracking Station.
  • Kerbals can die if they go without resources for too long. The defaults are: 360 hours without Food (60 Kerbin days/15 Earth days), 36 hours without Water, 2 hours without Oxygen, and 2 hours without Electricity.
  • Kerbals produce waste resources: Carbon Dioxide, Waste, and Waste Water. Currently Carbon Dioxide can be recycled into Oxygen, and Waste Water can be recycled into clean Water. Also can filter Oxygen out of IntakeAir, or split Water into Oxygen and Waste (hydrogen). A greenhouse part that allows growing Food is planned, but is not included yet.
  • Filling up with waste resources (Carbon Dioxide, Waste, Waste Water) has no effect. Any excess is dumped overboard, and you lose the opportunity to convert them back into good resources.

Includes the KSP Add-on Version Checker's MiniAVC. It does a GET request to http://ksp-avc.cybutek.net/ to find the latest release number. It is opt-in and no information is sent to the server. I recommend downloading the full KSP-AVC Plugin to get the most out of it. And encourage other mod authors to support it.
