## Why It Matters
Galaxy 18 is part of the global infrastructure of communications satellites that enable telecommunications services from geosynchronous/geostationary orbit. As an Intelsat-operated platform, it occupies a role typical of communications satellites: providing a stable, high-altitude orbital node for relaying signals and supporting broadcast, data, and other telecom uses. Its launch on 2008-05-21 using a Zenit-3SL vehicle from the Odyssey start point reflects the use of Zenit-series expendable carrier rockets for placing geosynchronous communications payloads into their intended orbits. The satellite’s formal identifiers (COSPAR 2008-024A, SCN 32951) and database entries (freebase, Wolfram) make it trackable and referencable in international satellite catalogs and technical records. For anyone tracking geostationary communications assets, satellite registrations, or Intelsat fleet history, Galaxy 18 is a discrete, identifiable element of that ecosystem.

## Notable For
