NASA TV on Galaxy 13
NASA Television’s channels NTV-1 (the Public/Education Channel) and NTV-3 (formerly the Media Channel) are in high definition. NTV-1 provides expanded programming of events of interest to the public and to educational audiences. NTV-3 provides mission coverage, news conferences and relevant video and audio materials to local, national and international news-gathering organizations. NASA's former NTV-2 channel, which provided educational programming in standard definition, has been discontinued.
All NASA Television channels are available on Satellite Galaxy 13. Specific parameters for each channel are listed below. NASA’s Live Interactive Media Service (LIMS) is KU-Band service. KU-Band parameters are provided prior to each event. NASA Television will schedule each LIMS event on a satellite in proximity of AMC-18 whenever possible. News networks, their reporters, and other broadcast media organizations must tune their satellite receivers to the NTV-3 to ensure reception of clean feeds for all mission coverage, news conferences, and other agency distributed news and information. NASA TV is available in continental North America, Alaska and Hawaii on Galaxy 13. A Digital Video Broadcast (DVB) compliant Integrated Receiver Decoder (IRD) is needed for reception.
