Telstar 18

Overview

Destination: Geostationary Orbit
Mission: Communications

Geostationary Orbit Launch Platform Odyssey Sea Launch

Telstar 18, launched June 28, 2004 aboard a Sea Launch Zenit-3SL rocket, has successfully reached its in-orbit testing position at 142 degrees East longitude. During the satellite's launch, the Zenit rocket's upper stage shut down 54 seconds early and released the satellite into a low orbit. After the launch, engineers at Space Systems/Loral (SS/L) raised the spacecraft to its correct orbit using a series of carefully planned satellite maneuvers and thruster burns.
