Telesat announced today that following the launch of Telstar 14R/Estrela do Sul 2 on an International Launch Services (ILS) Proton the satellite's north solar array failed to fully deploy.  
 
The south solar array has deployed successfully and is providing power to the spacecraft, which is stable and is otherwise operating as expected.  Space Systems/Loral, the satellite's manufacturer, is analysing data from the satellite to better understand the situation and determine what steps, if any, can be taken to attempt to rectify the north solar array deployment failure.  However, in the event the failure to deploy cannot be rectified, and subject to successfully completing the remaining deployments and post-launch maneuvers, it is expected that the satellite will, at a minimum, support all of the existing services to customers presently provided by Telstar 14/Estrela do Sul, the satellite it will replace at 63 degrees West.
