Environmental Control and Life Support Systems (ECLSS) are essential for sustaining human life in space by providing a controlled environment that includes air revitalization, water recovery, and waste management. This document serves as an overview of ECLSS and provides links to specific subsystems implemented as part of this project.
ECLSS consists of multiple interconnected subsystems to maintain habitable conditions for astronauts:
- Air Revitalization System (ARS): Handles CO₂ removal, moisture control, and contaminant filtration to maintain breathable air.
- Oxygen Recovery System (ORS): Converts water into oxygen through electrolysis and uses hydrogen recovery to form a closed-loop system.
- Water Recovery and Balance Systems: Processes crew urine, atmospheric condensation, and Sabatier-produced water for reuse.
- Temperature and Humidity Control: Regulates cabin conditions to ensure thermal comfort and moisture control.
Below are the specific subsystems implemented as part of this project. Click on the links to access their respective documentation.
The ARS is responsible for maintaining breathable air by removing CO₂, moisture, and contaminants from the cabin environment. The system consists of multiple ROS2 nodes working together to simulate air purification onboard the International Space Station (ISS).

The ORS simulates the oxygen generation process used on the ISS. It leverages electrolysis, Sabatier reaction, and deionization to create a closed-loop system that efficiently recycles oxygen from water.
