These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, are Europe’s highest-resolution pictures so far of the Martian moon Phobos. http://www.esa.int/SPECIALS/Mars_Express/SEM21TVJD1E_0.html |

I don't know about distortion -- Phobos looks pretty distorted in general; I can tell you from experience that it can be really hard to tell whether you have an oblique perspective or if an image has been unequally stretched. But I have a different question. There are two image releases that lack annotations. I thought that maybe they were the two views that had been combined to create the stereo image. But it appears that they are in fact the same image, stretched differently, and it seems that there was a gap in the image, some kind of data dropout, that was handled differently between the two images. In one the gap was closed, making an obvious seam; in the other, the gap was filled by duplicating pixels. I think that's what's going on anyway -- do others agree? The two pictures are
