Investigation of Early Symptoms of Microdestruction of Structures and Instrument Modules in the Russian Segment of ISS (Expert-1) - 02.25.15
Investigation of early symptoms of the surface microdestruction of the pressurized body and structures in the ISS RS instrument modules, conducted together with monitoring of temperature-humidity parameters, acoustic fields of ultrasound band and other spaceflight factors which can affect the microdestruction processes. Revealing of possible relations between microdestruction and spaceflight factors. Preparation of proposals for development of the onboard system to reveal early symptoms of microdestruction and updating of methods to prevent microdestruction of the pressurized body and structures in the ISS RS. Science Results for Everyone
There’s a fungus among us. Microscopic damage to the space station can lead to leaks in the structure. Temperature, humidity, microbes and other spaceflight factors can contribute to the damage. This investigation developed methods for monitoring and tracking these factors. Researchers also identified 30 potential problem areas that will be inspected regularly. Half of them are contaminated with fungi and bacteria. Monitoring also identified areas with insufficient air cooling, and proved that poor airflow contributes to microbial contamination. Images of fungi were stored in a database to help crewmembers identify them on the hull of the station. Experiment Details

Development of routes to provide monitoring of possible microdestruction zones based on the mapping results of background fields inside the ISS RS modules. Development of the initial option for the parameter data base providing a reliable identification of microdestruction growth symptoms. Assessment of a capability to use the temperature-humidity methods for probing, acoustic direction-finding, record of the surface microcondition onboard the station to develop the onboard system for early detection of microdestruction areas of the pressurized body, structures and hardware for the ISS RS.
