Mission
Partial control of the satellite was lost in July 2008 and completely in October 2008.
It was supposed to serve for 10 years, but already on 26 November 2008, due to a failure in the on-board digital system, it stopped responding to control signals. The failure was declared irreversible, and in August 2009, the satellite was transferred to a burial orbit.
