Just like last year, I’ve rounded up all the online Nasa-TV feeds I could find and stuck them all on one page.
I have 17 of them so far. About half of them are the ones listed on the Nasa Webcast page and the other half are links from elsewhere.
Anyway, enjoy!

Maybe we should also collect a list of who is broadcasting the kickoff, since many cable companies have added NASA TV secretly in the past few weeks. Personally, I know that Time Warner Digital Cable in the Los Angeles area added NASA TV yesterday at channel 113. This is in addition to DishNetwork carrying NASA TV in their basic package at 213 and DirecTV carrying it as part of DirecTV Plus at 376. Any other local companies that have added NASA TV?
