      More or less, those are dead pixels that have been killed by radiation over time. The same thing happens to cameras on the ISS.

        Well why would they not remove dead pixels after they download photos? If it is always the same pixel why aren’t they simply processed out and replaced with avg of neighbors? If it is radiation noise then they would need a few photos.
