A duplicate of the Mars Rover Curiosity in a simulated Mars envoironment at JPL on Wednesday, February 22, 2012. The room is bathed in light that is similar to the light on the martian planet. The hole pattern on the wheels spells out JPL in Morse Code and the tread pattern will leave an impression of the laboratory all over the Martian surface.  (Tim Berger/Staff Photographer)
