On Sol 16, August 22, 2012 the Curiosity rover took its first short drive and made its first tracks on Mars in Gale Crater. This activity was to check out the roving functionality of the wheels prior to its long drive to Glenelg. It would appear that Curiosity has started to accumulate dust on its Left Rear Hazcam.
