Launched separately in 2003, NASA's Mars Exploration Rover Mission involved a pair of twin rovers, named Spirit and Opportunity, which landed three weeks apart on the martian surface in January of 2004. The twins managed to make a number of important discoveries about possible wet environments on ancient Mars, that may have been favourable for supporting microbial life. While Spirit stopped communicating with controllers here on Earth in March 2010, Opportunity continues trek along across the landscape of Mars. The Mars Rover has been immortalised in this Metal Earth 3D laser cut steel model. Fully assembled, the model is approximately 7.6cm in length and 7.6cm wide and 10cm high. This is a Silver Edition Metal Earth Model, and features 2 sheets of laser cut pieces.
