- Abstract
Results of micrometeoroids and space debris flux measurements implemented in the time span from 2001 to 2006 by the Micrometeoroid Control System (MCS) on board of the Service Module (SM) of the International Space Station are presented for the first time after experiment completion. The goal of this experiment was to adjust spatial and time distribution model of space debris and meteoroid substance for10 –100 microns particle sizes in the range of the International Space Station orbit altitudes on the basis of the results obtained in the long duration measurements of particle's impacts detected by capacitor sensors mounted on the SM external surface. During the experiment 634 particles have been registered. In order to make a comparison of these experimental data with the data predicted on the basis of the existing meteoroid and space debris models the 3-D geometry model of the Service module has been developed and the number of particles penetrating upper and intermediate layers of each sensor were numerically calculated. The comparison of meteoroids and debris particle flux values obtained from this experiment with values obtained in similar experiments on board of "Salyut" and "MIR" space stations as well as with values obtained in other experiments were made. As a result it was possible to make a conclusion on growing of near-Earth space pollution in the range of the International Space Station orbit altitudes for particles in the size range between 20 and 100 microns.
