NASA TV is the television service of the United States government agency NASA (National Aeronautics and Space Administration). The network was formally created in the early 1980s to provide NASA managers and engineers with real-time video of missions. It is broadcast by satellite with a simulcast over the Internet.
NASA TV operates four channels – Public Channel, Education Channel, Media Channel and Space Operations Channel. The “Public Channel” provides 24-hour broadcasting of live and recorded events and documentaries aimed toward the general public. The “Education Channel” provides space and science programming for schools, museums, and other educational institutions. The “Media Channel” is dedicated to broadcast news organizations and other members of the press, featuring press release video, interviews, mission press conferences and other services. And the “Space Operations Channel” is basically an internal, encrypted feed for NASA spaceflight operations.
The NASA TV website also provides a channel featuring continuous live footage from inside and outside the International Space Station (ISS), as well as a continuous audio-only channel of ISS and Shuttle mission audio.
