Here is the latest selfie – perhaps the best yet. It is from the Big Sky drill site (you can see the Big Sky drill hole and the drill tailings) in the lower left. Curiosity itself is looking a bit dusty and with a few punctures in the wheels, but otherwise fine.
We are planning a second drill site on a silica-rich part of this Stimson unit to compare to the silica-poor Big Sky drill hole. This data is helping to change our view of Mars as solely a basaltic planet, some areas underwent extreme chemical fractionation.
