Monitor-E
Monitor-E is the first Russian satellite of a fleet of newly designed, small Earth observing satellites. It was launched August 26, 2005 (local time) from Plesetsk Cosmodrome, and placed in a Sun synchronous orbit of 540 km.
Design
Monitor-E has a set of remote sensing devices. They are intended to make maps of the Earth's surface to be used for ecological monitoring and chart geological features. It was built by the Khrunichev State Space Research Center.

Communications problems
After launch communications with Monitor-E was difficult to establish, initially. But a few hours later it was successfully contacted. On October 19 new problems developed and no communication was possible since then. Later on communications were restored and photographs from both cameras have been published on November 30, 2005.
