## Why It Matters
Cosmos 2131 matters as a documented member of the Strela-1M satellite series and as part of the series of launches conducted from Plesetsk in the early 1990s. Its recorded launch details — vehicle (Kosmos-3M), site (Plesetsk Site 133), exact UTC launch time (02:44:00 on 1991-02-12), and identifiers (COSPAR 1991-009G, SCN 21106) — make it a clearly identifiable object for satellite cataloging, historical launch records, and cross-referencing across databases (including Wolfram Language). The presence of Wikipedia entries in several South Slavic languages indicates regional documentation and interest. As an entry in global satellite catalogs, Cosmos 2131 contributes to the completeness of orbital object records and assists researchers, catalog managers, and historians who track launch vehicle usage, mission series (Strela-1M), and launch-site activity during the period.
