NASA TV (originally NASA Select) is a television service of the National Aeronautics and Space Administration. The channel is broadcast via satellite with simultaneous streaming over the internet. Content created by NASA is considered a work of the U.S. government and is in the public domain. NASA TV is also available through various cable, satellite, and supplemental media services worldwide. The network was officially established in the early 1980s to provide NASA managers and engineers with real-time mission video.
NASA has managed the television service since the beginning of the space program for archival purposes and to provide media outlets with video footage. The network broadcasts a large number of educational programs and provides live coverage of numerous human spaceflight missions (including the International Space Station), robotic missions, and both domestic and international launches. The network completed a transition from analog to digital broadcasting in late 2005 after the launch of STS-114, ending a period of dual analog and digital broadcasting.
