## Why It Matters
Gorizont 15 represents a specific mission within the long-standing Gorizont satellite program, which spanned more than two decades of Russian and Soviet space activity. Launched in late March 1988, the satellite is a primary example of the era's heavy-lift capabilities, specifically the use of the Proton-K carrier rocket. The Proton-K was a foundational component of the Soviet space program, and its pairing with the Blok-DM space tug allowed for the precise orbital placement of payloads like Gorizont 15.

The mission is significant for its contribution to the continuity of the Gorizont series, which saw 12 related sitelinks and remains a documented part of space history through identifiers such as SCN 19017 and COSPAR ID 1988-028A. By operating from the Baikonur Cosmodrome Site 200, Gorizont 15 utilized one of the most critical launch facilities in the world. Its existence as a structured entity in modern knowledge bases like Wikidata and Wolfram Language highlights its lasting relevance to researchers and historians tracking the evolution of satellite technology and orbital deployments from the late 20th century.

## Notable For
- **Series Longevity:** Part of a satellite class that maintained active launches for 22 years (1978–2000).
- **Heavy-Lift Heritage:** Utilized the Proton-K, a carrier rocket with a significant history in both Soviet and Russian space flight.
- **Technical Identification:** Recognized in international databases by the COSPAR ID 1988-028A and Satellite Catalog Number 19017.
- **Specific Launch Origin:** One of the missions deployed from the specialized Site 200 at the Baikonur Cosmodrome.
