1:1 Scale LEGO Mars Rover visits the Lego Store at the Paramus Park Mall, New Jersey USA. 3/15/04. {Mars Rover description, written from an offical sign} The LEGO Company first unveiled this full scale model of a Mars Exploration Rover with The Planetary Society in October 2002 at the World Space Congress. The rover model weighs 130 kilograms (290 pounds) and is made from approximately 90,000 LEGO elements. The rover model took 650 man-hours to build, and the construction process took about 3 months. A few details are not perfectly accurate to the final Mars Exploration Rover design, which was modified as it was being developed and tested. Overall, though, the model is the proper size and shape, with all the instruments, components and structures represented faithfully and to scale, from the four cameras on the top of the mast to the magnets in front and the Sundial in back. The LEGO Company has sponsored The Planetary Society's Red Rover Goes to Mars since its inception in 1998. Photos, by Eric Sophie 2004
