Basic results of post-flight researches of solar array (SA)returned to the Earth from the orbital space station “MIR”after 10.5 years of operation

摘要

Visual control and instrumental analysis of electrical, optical,mechanical and thermophysical parameters were conducted with the SAreturned to the Earth after 10.5 years exposure in LEO environment. Thechemical analysis of the contamination was done, the influence ofmeteoroid environment on the surface condition of SA was defined. Themain reason connected with SA partial shadowing and SA degradationmechanism under the influence of this factor are established
