The Mars Science Laboratory rover, to be launched in 2011. The only creation of mine up here from the last 3 years.
About this creation
NASA's Mars Science Laboratory rover, which will cruise around Mars in 2012 if all goes well. Getting the scale right (particularly with the wheel system), getting the rocker-bogie to work well, and the RTG in the back were definitely the trickiest parts of this. Granted, rocker-bogies are always hard to balance with Legos, but this was no exception.
