I know this has been posted on other boards, but I'll ask here: is Fios considering adding NASA-TV to its lineup? (I think NASA's even offering some HD content now)
I know HDNET carries launches, but that's not the same as the 24/7 coverage of all things space and NASA related that NASA-TV provides.
It might have been discussed here as well. Unfortunately, Vz doesn't tip their hand when it comes to adding channels. Some subs get NASATV as a substation on their locals and others can get it on their public service channels, but the majority can't get it.
As you stated, HDNET is our only source, but that's mostly launches and recoveries. For everything else you have to log on to NASA.gov.
Add me to the list, I want NASA TV. I was very sad to find out that it wasn't already part of the line up. If I had known this I would not have signed up for FIOS.
