Wall hanger: "Next step Mars?"

The set is designed to hang on the wall (see photos) - which should appeal to adults, and please a lot of parents!

I wanted to use only basic Lego pieces, to reflect the technology (and indeed Lego!) which was itself very basic back in the heady days of the Space Race.

The set stands upright and measures 3 x 16 studs (and 26 studs high).  Piece-count is approx. 280.
