Objectives:

  • Updating meteoroid and technogenic environment model at altitudes of the Station flight in hazardous and unobserved by other aids particle size range (0.1-1.0 mm) in the interests of development of the flight equipment for monitoring meteoroid and technogenic hazards;
  • development test of the equipment recording the particle impacts on the Station external surface to develop a system for online determination of coordinates of the Station pressure shell breakdown points.

Tasks:

  • Installation of equipment, cable laying and connection;
  • Hardware operation in automatic mode.

Science Hardware Used:

Science hardware OTKLIK consisting of:

  • monitor unit (MU);
  • operator console (OC);
  • primary piezoelectric converters (sensors) with preamplifier (13 pcs);
  • cable network.

Expected results:

Data on record rate of meteoroid particles and their parameters obtained at sufficiently long time intervals (several years) will be used for updating the environment models when calculating a risk of damage of separate ISS elements, as well as for accepting decisions on inspection of the Station external surface at points of the most strong impacts.

Experiment results:

Information with impact parameters as files with digital arrays to be downlinked to the ground through БИТС2-12 channels.
