At 19:55 UTC on Oct. 15, an Angara 1.2 rocket launched from Site 35/1 at the Plesetsk Cosmodrome carrying a payload for the Russian military to a Sun-synchronous Orbit (SSO).
The exact identity of the payload is not known, other than it received the Kosmos-2560 designation upon reaching orbit. While initially suspected to be a small military optical reconnaissance satellite designated EMKA-3, new reports offer the payload is part of a different series of satellites and is designated EO MKA No. 3.
