ISS gets life support system that turns CO2 into oxygen
The International Space Station (ISS) is being installed with Advanced Closed Loop System (ACLS), which is a life-support system developed by the European Space Agency (ESA). The system recycles half the carbon dioxide (CO2) exhaled by astronauts and converts it into oxygen. It could save about 400 litres of water requirement on ISS each year, the researchers claimed.
