If it’s too much for you, perhaps you woluld like to try with paper model of a satellite? Visit http://www.astronautilus.pl/model.pdf website to find a PW-Sat paper model, prepared to be made in 1:1 scale. It’s very rare occasion to have in your hands model of the satellite, that is identical in shape and size to the original object. All you need is a printer, scissors, glue and a half an hour of great fun. What you get, is a your own PW-Sat satellite. Can you imagine the model hanging on your Christmas Tree?
