Technical Research on ISS Russian Segment

Experiment Expert


Objective:

  • 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.

Tasks:

  • 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.
