## Why It Matters
Cosmos 852 is a documented member of the Zenit-4MK series and is part of the record of Soviet-era launches during 1976. As a named and catalogued spacecraft with both COSPAR and SCN identifiers, it contributes to the continuity of orbital asset tracking and historical launch records. Its launch on a Soyuz-U vehicle from Baikonur Site 31 exemplifies the use of the Soyuz-U launch family and Baikonur infrastructure during that period. For researchers, historians, or cataloguers, Cosmos 852 provides a concrete data point linking spacecraft class (Zenit-4MK), launch vehicle (Soyuz-U), and launch infrastructure (Baikonur Site 31) on a specific date and time. Its entries in multiple language Wikipedias and a Wolfram Language entity record further show that Cosmos 852 is recognized across data and reference systems used for satellite identification and historical reference.
