Life support is about maintaining the environment in the ship. So the system should handle these aspects
Environmental
- Air quality - you have that
- Temperature control, heating and cooling the air, and controlling the humidity
Water system
- Recycling, filtration and purifying - pretty much have that
- Waste systems, this includes bodily solid waste, but also trash and scraps from food prep
Gravimetrics
- You need some sort of artificial gravity system, or all of your environ systems have to be made to work in zero-g.
- Inertial compensation, you want some sort of system that will protect the occupants of the ship from high g maneuvers.
