Inside the International Space Station (ISS): NASA Environmental Control and Life Support System (ECLSS) Astronaut Training Manual

Learn about the International Space Station (ISS) from the textbooks used by the astronauts! These astronaut and flight controller training manuals, produced by the Mission Operations Directorate (Space Flight Training Division branch) at NASA's Johnson Space Center, represent a major part of the formal flight crew training process. The manuals and workbooks are extremely detailed and comprehensive, and are designed for self-study. A full listing of all acronyms and abbreviations used in the text is included. They provide a superb way to learn about Station systems, hardware, and operational procedures. Special emphasis on crew interaction with the displays, controls, and hardware is included.

This up-to-date training manual covers the crucial Environmental Control and Life Support System. The Environmental Control and Life Support System (ECLSS) maintains a pressurized habitable environment, provides water recovery and storage, and provides fire detection and suppression within the International Space Station (ISS). ECLSS provides a pressurized and habitable environment within the Space Station by supplying correct amounts of oxygen and nitrogen, controlling the temperature and humidity, removing carbon dioxide and other atmospheric contaminants, and monitoring the atmosphere for the presence of combustion products, as well as major constituent proportions. The system also collects, processes, and stores water and waste used and produced by the crewmembers. Fire suppression and crew safety equipment are provided. The primary ECLSS concern, whether directly or indirectly, is with the ISS atmosphere. This manual presents ECLSS through its subsystems, starting with Atmosphere Control and Supply (ACS), then Atmosphere Revitalization (AR), Temperature and Humidity Control (THC), Fire Detection and Suppression (FDS), and finally Water Recovery and Management (WRM).
