Cargo spacecraft like SpaceX’s Dragon and Russia’s Progress vehicles deliver fresh water and replacement parts, ensuring the system can continue functioning at peak efficiency for the duration of the expedition. While electrolysis handles the majority of oxygen production, the ISS also employs solid fuel oxygen generation technology as a backup.
International Space Station Oxygen System Integration and Redundancy Mechanisms
Water recovery from humidity and condensation is essential for the electrolysis process. Although the system recycles oxygen from water, some losses occur during the venting of hydrogen and other processes.
The Oxygen Generation System, often referred to as the OGS or the Elektron units, draws water from the station’s atmosphere and waste recycling systems. This chemical process is not reliant on the station’s power grid, making it a vital redundancy in case of electrical failure or maintenance issues with the primary electrolysis units.
International Space Station Oxygen System Integration and Redundancy
Oxygen is stored in high-pressure tanks before being released into the cabin atmosphere. Redundancy is built into every stage to prevent a single point of failure.
