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.[3] The satellite entered service with reduced capacity (17 transponders) and reduced life span of 7 years with the jammed panel.[4] 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. LaunchThe Telstar 14R replacement was launched in May 2011 from the Baikonur Cosmodrome in Kazakhstan aboard an International Launch Services Proton-M rocket. This replacement satellite, Telstar 14R experienced the same problem, with its north solar array failing to open. The Telstar 14R replacement satellite is in service, despite that deployment failure.[5] {{Clear}}See also{{Portal|Spaceflight}}
