Anyone old enough to remember Apollo 11 landing?
I am and I recall that the picture was just a white splodge on a black background. Admittedly, we only had B/W but some of my school friends had colour TV and I asked them what they saw (me expecting colour to show more details). Almost all of them said they hadn't watched it live. I think there was only about 3 or 4 of us in the class that had watched it live.
Most satellites store data on board the spacecraft and then it is downloaded at regular intervals. The down load needs an extensive team as you need to:
1 - Calculate exactly where the spacecraft is;
2 - Point the antenna to the spacecraft;
3 - Initiate the download (this usually stops recording on device #1 and starts recording on device #2);
4 - When the download is complete, start downloading from device #2 and restart device #1 (sometimes the recording is left on the second device and that is downloaded at the next schedule);
5 - Release the antenna team so they can start working on other satellites.
This requires at least 4 teams and they are almost always shift workers so that is a minimum of 20 people (to allow for time off and covering 24 hours per day).
