Curiosity wheel survey, sol 660 On sol 660 (June 15, 2014), Curiosity performed a series of short drives followed by MAHLI imaging of each of the wheels, to survey their condition. Here, the images have been sorted and the inter-cleat spaces numbered to make it easier to survey the locations of specific marks, tears, and punctures. NASA / JPL / MSSS / Emily Lakdawalla
