'''Life support''' is vital to the survival of a [[ship]]'s [[Crew Member|crew]] and [[Civilian|passengers]]. It consists of systems that regulate an oxygen-rich, [[CO2|CO<sub>2</sub>]]-poor [[atmosphere]] of the engineering and [[Habitation Deck|habitation]] decks.
A [[ship]]'s [[Crew Member|crew]] and [[Civilian|passengers]] require:
- Oxygen
  - Crew can survive in [[spacesuits]], so long as they are refilled with oxygen periodically, but civilians can't wear spacesuits and require an [[atmosphere]].
- [[CO2|CO<sub>2</sub>]] removal (if an atmosphere exists).
- [[Food]]
- [[Water]]
- [[Sewage]] removal is not yet required (as of Alpha 14), but presumably will be at some point.


The [[Getting Started#Atmosphere|most basic life support system]] consists only of an [[airduct]] connected to [[oxygen]] and [[power]] sources. During a standard game, this will likely consist of a [[reactor]] and an airduct, each connected to loaders and supplied with [[oxygen]] and [[fuel]] [[container]]s. However, this system's shortcomings become apparent as the CO<sub>2</sub> level rises.
Oxygen, food, and water can all be purchased (or retrieved from post-combat debris), and CO<sub>2</sub> and sewage can be sold.


== Removing CO<sub>2</sub> ==
With the right equipment, the player can recycle CO<sub>2</sub> and sewage back into oxygen, food, and water. [[Research]] can increase how much is recycled.


The ship's population will slowly generate CO<sub>2</sub>, which will build up in the atmosphere. If the CO<sub>2</sub> level becomes too great, the population will begin to suffocate. To keep a healthy atmosphere, the CO<sub>2</sub> must be removed by using a [[CO2 Scrubber]], which can be connected to an [[Air Reprocessor]] to generate oxygen.
Additionally, [[waste water]] can be harvested from [[ice comet]]s with [[mining laser]]s and then purified. Oxygen can be produced from water with an [[Oxygen Maker]], though this risks using up the water supply if not monitored.
 
If the CO2 Scrubber says it is "blocked," this means that the output has nowhere to go. In this case, connecting a tank to the CO<sub>2</sub> pipe is good practice.
 
== Refilling spacesuits ==
 
[[Spacesuit]]s contain 100 units of oxygen each, allowing crew members access to a breathable atmosphere in the event of a hull breach. Spacesuits can be refilled by installing a [[Spacesuit Pod]] connected to an oxygen line. Crew members will bring the suits, one by one, to the pod to refill the oxygen tanks.
 
== Separating atmospheres ==
 
On vessels that carry civilians, it is advisable to create separate atmospheres. Civilians can't wear spacesuits, and the atmosphere passes freely through ladders to and from the [[Habitation Deck]]. If the area beneath a ladder loses atmosphere, so does the area of [[Habitation Deck]] it is connected to. The player can help keep civilians alive in case of hull breaches by separating the ladder area from the rest of the ship's atmosphere by installing a hull, a door, and an airduct with a proper oxygen supply.
 
== Connecting to other systems ==
 
When creating a self-sufficient ship, players can look into connecting the output of a functioning [[Logistics#Sewage processing|sewage processing system]] to the life support system via an [[Oxygen Maker]]. This helps to create oxygen from [[water]] but also requires keeping an eye on the oxygen and water levels to ensure they are within reasonable levels. In some cases, the oxygen maker might overproduce oxygen and leave no water for the population to drink, leading to dehydration.

A ship's crew and passengers require: - Oxygen 

 - Crew can survive in spacesuits, so long as they are refilled with oxygen periodically, but civilians can't wear spacesuits and require an atmosphere.

- CO2 removal (if an atmosphere exists). - Food - Water - Sewage removal is not yet required (as of Alpha 14), but presumably will be at some point.

Oxygen, food, and water can all be purchased (or retrieved from post-combat debris), and CO2 and sewage can be sold.

With the right equipment, the player can recycle CO2 and sewage back into oxygen, food, and water. Research can increase how much is recycled.

Additionally, waste water can be harvested from ice comets with mining lasers and then purified. Oxygen can be produced from water with an Oxygen Maker, though this risks using up the water supply if not monitored.
