As we get closer to the launch of Curiosity, the more excited and interested I become.  I think I first saw the video above in 2008, and was quite impressed- but on July 9th, 2010, engineers have installed and rotated Curiosity’s wheels for the first time! It’s hard to even fathom those wheels will travel the 4.16ish light minutes through the vacuum of space to eventually tear up untouched Martian soil.  It gives me hope that one day we will be able to reach our potential as human beings.
