## Why It Matters
Cosmos 504 is a documented example of the Soviet Strela-1M series of spacecraft and illustrates the routine operational activity of the USSR space program in the early 1970s. As an entity with a COSPAR identifier and a spacecraft catalog number, it contributes to the historical and technical record used by space historians, catalogers, and orbital analysts to track space assets and launches. Its launch from Plesetsk Site 132 aboard a Kosmos-3M highlights the use of medium-class launch vehicles and the Plesetsk facility for placing military and communication-class satellites into orbit during that period. Entries like Cosmos 504 help map the deployment cadence and infrastructure of Cold War-era space operations and support continuity in satellite cataloging across decades. The availability of entries in multiple Wikipedias (mk, sh, sr) also indicates continued regional interest in documenting Soviet-era space missions.
