The International Space Station (ISS) United States Operational Segment (USOS) received the first two permanent ISS Crew Quarters (CQ) on Utility Logistics Flight Two (ULF2) in November 2008. As many as four CQs can be installed in the Node 2 element to increase the ISS crew member size to six. The CQs provide crew members with private space that has enhanced acoustic noise mitigation, integrated radiation-reduction material, communication equipment, redundant electrical systems, and redundant caution and warning systems. The rack-sized CQ system has multiple crew member restraints, adjustable lighting, controllable ventilation, and interfaces that allow each crew member to personalize his or her CQ workspace.
The deployment and initial operational checkout during integration of the ISS CQ to Node 2 is described in this paper. On-orbit to original design performance is also compared for the following key operational parameters: interior acoustic performance, airflow rate, temperature rise, and crew member feedback on provisioning and re-straint layout.
