Starship Asterisk*

I have a question about the picture from February 3, 2005. It appears
as though all the shadows on the craters are on the right side.
However, the shadows on the uplift in the center the large crater is on the left side. Is this simply an illusion or is there a more complex solution?

I don't see this, although apparently it's quite common. See this ESA write up.

OK, so I see this picture of "craters" and I'm confused, cause it looks like bumps. So I download the picture by clicking on it, following the link shows a 90 degree cw rotation of the image. (still seeing bumps)
I load it into photoshop and rotate the image back to the original orientation and reverse the colors, tada now it looks like craters, but odd color. meh
D'oh! now I try horizontal flipping, and it works fine, as does a 180 degree rotation fro the original, or 90 deg cw from the file.

Now the cool part:
In one degree increments I rotate the image back ccw, I can get to about 45 degrees ccw before starting to lose the "craterness" of the objects in the picture. Then if I look away from, say, a 30 ccw rotation... bumpy again.
So my brain can be trained, a bit, to see it correctly. Might work better if I tried it with a printout.

It's like a one page optical illusions book.

I liked the esa link too, thanks.

that is truely incredible.
