## Why It Matters
Cosmos 2021 is a documented example of the Soviet Yantar-1KFT reconnaissance satellite program and illustrates the ongoing use of Soyuz-U rockets and the historic Gagarin's Start launch pad for military and intelligence missions during the late 1980s. As a Yantar-1KFT-class satellite, it belongs to a family of spacecraft designed for reconnaissance, and its formal registry entries (COSPAR ID 1989-037A and SCN 20000) provide stable identifiers used by catalogues and analytical tools (for example, the Wolfram Language entity code). The mission's recorded launch particulars—date, time, vehicle, and pad—make Cosmos 2021 a traceable data point for studies of Soviet space operations, launch-vehicle utilization, and the chronology of intelligence-satellite deployments in 1989. Its presence in multiple-language Wikipedia entries indicates some public and archival recognition.
