## Why It Matters
Gorizont 25 is part of the long-running Gorizont series, a sustained Soviet and later Russian program of satellite launches spanning 1978–2000. Each satellite in that lineage represents continuity in Soviet/Russian space operations and reliance on the Proton-K launcher family for heavy payload delivery. The recorded launch details (date, launch site, vehicle, and upper stage) document a specific operational profile of early 1990s Russian space activity and contribute to the historical and technical record used by satellite catalogs and databases. The satellite’s identifiers (COSPAR ID 1992-017A and scn 21922) allow researchers and operators to unambiguously cross-reference its launch and tracking records across international registries and data systems such as the Wolfram Knowledgebase and the Google Knowledge Graph.

## Notable For
