I've received two questions very frequently from readers: "Have they taken another look at Holy Cow yet to see if it's changed?" and "What were those splotches on the leg of the lander in the first image of Holy Cow?" Well, I can now tell you that the answer to the first question is "yes" -- they re-imaged Holy Cow yesterday, sol 31. And there's no official statement from the team yet, but I've looked at the photos and if there is any change, it's very subtle, and impossible to prove from the raw images that are available from the mission website. The team has better data, of course, and may be able to see subtle differences that I can't; but with what I have in front of me I don't see any differences between the two images that can't be explained away as differing shadows, compression artifacts, or a result of a slightly different position of the robotic arm for the two images.
...my raw images web page is updated to sol 31.
