Summary
COSMOS 2051, also known as Kosmos-2051, is an ocean surveillance satellite launched on November 24, 1989, from the Tsyklon launch site using a Tsiklon-2 launch vehicle. The spacecraft has dimensions of 10 meters in length and 1.3 meters in diameter, with a span of 17 meters, indicating it likely includes deployable solar arrays or other structures. Its dry mass is 3,000 kilograms while its total launch mass was 3,300 kilograms. The satellite, manufactured by ARSL/KOMET for VMF (likely referring to the Soviet Navy), operates passively in surveillance of ocean activities. It features two deployable fixed solar arrays and batteries as its power source. COSMOS 2051's payload is identified as US-PM No. 11L and it was part of a larger constellation or fleet for ocean monitoring purposes, with no additional information provided on major events or materials composition.
