Telstar 14 or Estrela do Sul 1 (Southern Star 1) is a commercial communications satellite in the Telstar series built by Space Systems/Loral (SS/L) for Telesat to provide Ku-band communications to South America and the Southern United States.

Estrela do Sul 1 was launched by Sea Launch using a Zenit-3SL carrier rocket on 11 Jan 2004 for geosynchronous orbit at 63 degrees west.

The North solar array failed to open after launch, limiting the mission effectiveness. The president of SS/L later said images of the satellite in orbit showed massive damage to the affected array, indicating that an explosion had occurred during launch.{{cite web |url=http://www.spacenews.com/satellite_telecom/120607-is19-solar-problem-sealaunch.html |archive-url=https://archive.today/20130104173701/http://www.spacenews.com/satellite_telecom/120607-is19-solar-problem-sealaunch.html |url-status=dead |archive-date=January 4, 2013 |title=Probe of IS-19 Solar Array Problem Focuses on Sea Launch Rocket |date=7 June 2012 |publisher=Space News}} The satellite entered service with reduced capacity (17 transponders) and reduced life span of 7 years with the jammed panel.{{cite web |url=http://space.skyrocket.de/doc_sdat/telstar-14.htm |title=Estrela do Sol 1 |publisher=Gunter's Space Page |accessdate=2 June 2012 }}

Estrela do Sul 1 / Telstar 14 and Estrela do Sul 2 / Telstar 14R are built around the Loral 1300 satellite bus, and have launch mass of around 5000 kg.
