Telstar 14R, also known as Estrela do Sul 2 (Southern Star 2) is a commercial communications satellite in the Telstar series built by Space Systems/Loral for Telesat to provide Ku-band communications to South America and the Southern United States. It is a replacement for Telstar 14, whose north solar array failed to open after launch, limiting its mission effectiveness. Telstar 14R experienced the same problem, with its north solar array failing to open too, but is now in service despite that failure.{{cite web|url=http://www.spacenews.com/satellite_telecom/110525-stuck-array-telesat-samerica-push.html|archive-url=https://archive.today/20120526083821/http://www.spacenews.com/satellite_telecom/110525-stuck-array-telesat-samerica-push.html|url-status=dead|archive-date=May 26, 2012|title=Balky Satellite Solar Panel Threatens Telesat's Growth Plans in S.
