Statistical Analysis of Micrometeoroid and Space Debris Impacts on the Space Station "Salyut-4"

It is common to consider the flow of micrometeoroids and space debris (MM/SD) as the Poisson one when calculating risks for spaceship [1]. However even the first studies of the near Earth space with the aid of spaceships where sensors of particle registrations have been set allow us to suppose that registered streams have very complex features [2-3].The objective of this work is the statistical analysis of MM/SD registration data onboard station "Salut-4" and specification of their distribution models in the near Earth. As initial data we used results of studies performed on stations "Salyut-4" and obtained with the help of the control system. This system was used for detecting of the MM/SD impacts and consisted of condenser sensors (CS) and an electronic device.
