I assume you meant WHERE IS NASA TV. It has been requested over and over again (even had its own request thread) but still no sign that Verizon is going to add this NO COST channel
The tech that started that Nasa thread awhile back said it was too late to add it in 2009, but that it would be added in 2010, so we'll have to wait and see if he was right.
Next Shuttle is scheduled to launch February 4th. They better have NASA TV up by then. Boy do I miss my Direct TV.
I wouldn't count on it being there. Verizon has made no definitive committment to add NASA TV (either SD or HD).
Really the best thing next to my Big screen TV and TiVo, is the PC that gives me a live feed from. http://www.nasa.gov/
It is really hard to comprehend why Fios will not add this when there is an open feed.
