NASA TV (originally NASA Select) is the television service of the United States government agency NASA (National Aeronautics and Space Administration). It is broadcast by satellite with a simulcast over the Internet. Local cable television providers across the United States and amateur television repeaters may carry NASA TV at their own discretion, as NASA-created content is considered a work of the U.S. government and is within the public domain. The network was formally created in the early 1980s to provide NASA managers and engineers with real-time video of missions. NASA has operated a television service since the beginning of the space program for archival purposes, and in order to provide media outlets with video footage.

My only complaint is that the user system and its interface is very buggy and needs some work. I've had sessions where I've had to log onto every page I went to because it kept logging me out and I was confused more than once by the interface itself. I love N.A.S.A with a passion and I fully support this site
