On sol 886 Oppy's microscopic imager takes shots of a new type of stone previously unseen in Meridiani planum. This place was already shot on sol 885 by the Panoramic Camera, showing a patch of soil looking like gravel.
These stones are clear, chalky looking, with angulous fractures, but slighty rounded as if transported for a while in a river bed. They also show some hollows or veins in some places. In the background there are small more or less rounded stones evoking the smaller blueberries already seen in the beginning. So I wonder what these stones could be. The most conservative explanation would be that they are freshly broken jarosite, submitted to a bit of eolian erosion. But other explanations are possible. We shall remain in the expectative until some analysis is done. |
