Born in 81 here. One of my childhood memories is of watching the broadcast of the flyby of Neptune in 89. I believe it was on PBS, or something similar.
I just looked it up, they had something called Neptune at Night that broadcast from midnight to 9AM. I probably caught it in the mornings before school.
I was too young to know what it was. He had some big dish antennas that he was always futzing with, and I'm sure he was using one of those, but I presume it was some kind of relay signal. Unfortunately I'm not a radio guy.
So, what was the "satellite feed" mentioned in the story? Was it a regular TV broadcast, or something more internal distributed by NASA?
