Choice and Development of Methods and Instruments to Detect the Location of a Loss of Pressurization of a Module on ISS (Bar-1) - 02.25.15
Information Pending Science Results for Everyone
Leaky vessels are a problem, especially in space. This investigation tested ways of detecting loss of pressure and the existence of leaks in space station modules and working compartments. Results verified performance of the testing equipment and identified 56 potentially hazardous leaks, along with potential problem areas on the station’s pressure hull. Researchers created several databases to track these potentially hazardous leaks, problem areas, and the current condition of the station’s pressure hull. Additional data will be used to train crew members to identify surfaces where problems might develop. Experiment Details
