I do not know, if card models are of any interest to you, but next year it is 50 years since the Prospero satellite was launced
on 28 October 1971 at Woomera, South Australia.
I have created this free model of the satellite and it can be downloaded from my webpage:

You are welcome to check out my other models at
http://www.nielspapermodels.com/models.htm
There is models of the Black Arrow launcher and Blue Streak missile.
