The Cosmos 2555 (Kosmos 2555) Russian military codenamed satellite, which was launched from Plesetsk on 29 April by an Angara 1.2 rocket, has not performed any manoeuvres in its very low Sun-synchronous orbit. Analysts now think that the satellite, which is suspected to be a Razbeg/MKA-R class small optical satellite, either failed immediately after launch, or that it was always meant to be a dummy satellite. The satellite is now expected to re-enter in the next few days.
