Life Support Systems of the International Space Station
The International Space Station is a collection of different pressurized modules and structural components provided by all the world major space agencies. The station is split in a Russian and a US segment, and each provides its own environmental control system aimed at creating and maintaining a safe comfortable living environment for the astronauts. The station relies on a stream of supplies sent from Earth to replenish consumables such as oxygen and water. However, within the US segment, a regenerative environmental control system has been installed, thanks to which wastewater and carbon dioxide are reclaimed to produce potable water and oxygen. This has resulted in a 65% of savings in resupplies reducing the overall cost of maintenance of the outpost.
