Note to viewers: On July 31, 2012, NASA.gov discontinued streaming NASA Television in the QuickTime and Windows Media proprietary formats. The change helped us to simplify our webcasting infrastructure. The site will continue to stream NASA Television and NASA Newsaudio in Flash and HTML 5 for iOS devices.
