This fan made expansion is an extremely challenging map set on the Moon where half the cities are always black and the track can be built off one side of the board, only to appear on the opposite side.
The Moon expansion was originally a limited, paper only, release of 180 copies for Essen 2005. It was initially packaged with Age of Steam Expansion - Reunion Island in a special box. In 2007, the Moon was reprinted as the flip side to Age of Steam Expansion - Mars: Global Surveyor. The print run of the second edition was 100.
