Product Description LEARN ABOUT OUR NEW SPACE STATION FROM THE TEXTBOOKS USED BY THE ASTRONAUTS! These astronaut and flight controller training manuals, produced by the Mission Operations Directorate (Space Flight Training Division branch) at NASA's Johnson Space Center, represent a major part of the formal flight crew training process. The manuals and workbooks are extremely detailed and comprehensive, and are designed for self-study. Each is heavily illustrated with vivid line drawings, engineering schematics, and other charts and figures. A full listing of all acronyms and abbreviations used in the text is included. Most include self-test questions and answers. They provide a superb way to learn about Station systems, hardware, and operational procedures. Special emphasis on crew interaction with the displays, controls, and hardware is included. This up-to-date training manual covers two major areas: Thermal Control Systems and the emergency EVA propulsion backpack known as SAFER. It contains 133 excellent illustrations, figures, tables and charts. THERMAL CONTROL SYSTEM: Throughout the life of the Space Station, experiments, equipment, and crewmembers inside the modules are generating heat that must be removed. Outside the modules, experiments and equipment must be protected from the environment in low Earth orbit. The purpose of the Thermal Control System (TCS) is to maintain Space Station equipment and payloads within their required temperature ranges. TCS Architecture - The Space Station TCS is composed of Passive and Active thermal control systems. The Passive Thermal Control System (PTCS) consists of insulation, coatings, heaters, and heat pipe radiators. Its components generally have few operational requirements and require low maintenance. PTCS components are also less complex and easier to implement. The Active Thermal Control System (ATCS) uses a mechanically-pumped fluid to perform heat transfer. Although this approach is more co
