You're right that Stickney is about equidistant between the leading apex and the sub-Mars apex, but the splat trials to the sub-Mars side. Here's a version of the image, rotated so that north is upright. It's an almost perfectly equatorial view of the sub-Mars hemisphere (just a hair more to the north than equatorial). Remember, everybody, that nearly all Mars missions are in pretty low-altitude, circular orbits, much lower altitude than Phobos orbits, so they can see only as much of Phobos as we can see of our own Moon: the sub-Mars hemisphere. I've been debating starting to call this the "nearside" of Phobos to help bring home that point, but I'm not sure if that will be any less confusing than "sub-Mars hemisphere." Of the orbiters at Mars since Viking, only Mars Express has an elliptical orbit that allows it to see other parts of Phobos.

I actually like this version better, think I'll make it this way on the Society web pages...
