A Russian Soyuz-2.1b rocket was launched from Site 43/4 at the Plesetsk Cosmodrome on Dec. 1 at 12:10 AM Moscow time (21:10 UTC on Nov. 30). Onboard was likely a Lotos-S electronic intelligence satellite for the Russian military.
There is a possibility that additional payloads are to be deployed by the primary satellite later, based on unclear state news reports. Only Lotos-S1 No. 6 and its Soyuz upper stage were initially cataloged in orbit.
