Memoirs of a Space Engineer - Leadpencils

And that video was interspersed amongst all that telemetry data. So in fact the video data rate was very slow. 40,000 pixels per 8 hours, 5,000 pixels per hour, 83 pixels per minute, 1.4 pixels per second.

Being nosey buggers as we were, we just had to do something about this. So we got a large sheet of graph paper and marked it out into 200 x 200 squares. Each square was divided up into 4 smaller squares. And we armed a team of 8 people each with a lead pencil. As the data came back, according to the video data value we would shade in a number of the squares. When viewed from a distance it gave quite a representable picture.
