NASA switching its Public Channel and Media Channel to HD
Picture by NASA
The NASA HD channel that you may or may not have is going away. In its place is the NASA Public and Media Channels. They are going to be switched to HD when the transition. Now most TV providers will just carry the channel like any other channel, or they could down convert to SD if they don't have enough bandwidth. Do take a look of the picture above. One thing that will stay the same is the NASA Education Channel. That will stay in SD. That picture is amazing, you have to admit.
