Abstract

The “Spektr” satellite will be launched in a high-elliptic orbit (600 km perigee ,  330 000 km apogee, initially). The spacecraft consists of about 13 components to run measurements on gamma-ray, radio, and ultra-violet astronomy. This scientific space mission is a rather expensive enterprise, and it is required to control the risks.   The spacecraft will be far from the Earth for the most part, so the main danger is meteoroid impacts.  The meteoroid protection the damage risk can be described using  following parameters:
-the probability density distribution of failures, experienced by the equipment units as a result of random or wear-out effects, i.e. not meteoroid-induced,
- the probability density distribution of  damaging hypervelocity impacts,  
– the cost of the manufacture and launch of the satellite. 
Results of protection optimization using the method of hyperbolic finite elements are given.
