The Crew and Thermal Systems Division (CTSD) is part of the Engineering Directorate at the NASA Johnson Space Center. CTSD engineers design, develop, and test technologies to support humans in space. Systems include environmental control/life support (ECLSS) and active thermal control (ATCS) for spacecraft, as well as crew equipment, tools, and spacesuits for intravehicular activities (IVAs) and extravehicular activities (EVAs). CTSD also provides test capability in both vacuum and thermal/vacuum environments using specialized human test facilities.
