How to get rid of carbon dioxide in the space stations.
A space free of CO2
August 10, 2007 - This view of the Space Shuttle Endeavour clearly shows its payload bay and upper surfaces. The image was photographed by one of the Expedition 15 crewmembers aboard the International Space Station shortly before the two vehicles docked in Earth orbit. Endeavour is contributing toward space station construction by delivering a third starboard truss segment, S5, and supplies inside the SPACEHAB module (in the center of the bay) and the external stowage platform 3. A Russian spacecraft, docked to the station, can be seen in the right foreground
