This website provides the resources needed to build the entire planet Mars out of paper. For practical reasons it is 54,160,000 times smaller and a little more angular than the actual planet.

While illustrator Edi Ettlin is working on a children's book of which the paper Mars will be a part, the trial version of the model is available for download in English and in German. It comes  along with a key to unlock some of Mars' secrets.
