Overview of Carbon Dioxide Control Issues During International Space Station/Space Shuttle Joint Docked OperationsManned space vehicles have a common requirement to remove the Carbon Dioxide (CO2) created by the metabolic processes of the crew. The Space Shuttle and International Space Station (ISS) each have systems in place to allow control and removal of CO2 from the habitable cabin environment. During periods where the Space Shuttle is docked to ISS, known as joint docked operations, the Space Shuttle and ISS share a common atmosphere environment. During this period there is an elevated production of CO2 caused by the combined metabolic activity of the Space Shuttle and ISS crew. This elevated CO2 production, combined with the large effective atmosphere created by the collective volumes of the docked vehicles, creates a unique set of requirements for CO2 removal. This paper will describe the individual CO2 control plans implemented by the Space Shuttle and ISS engineering teams, as well as the integrated plans used when both vehicles are docked. In addition, the paper will discuss some of the issues and anomalies experienced by both engineering teams.
