The HiRISE team today released two images of Mars' moon Deimos, taken on February 21, 2009:

Nice confirmation that my MRO model in Celestia works well.
Awesome, thanks for the heads up.
Reality check: I am figuring out the geometry, using my marvelous cut-and-assemble Deimos model. It's telling me that the two photos are of the sub-Mars hemisphere (only hemisphere it could be, given MRO's orbit, so that's reassuring), but it appears they've been released with the south pole up. Do others agree?

Anyone for 3-D? It ought to work at least for the upper right portion of those images.
Yep South pole is up. In the third view, the blue arrow is from the north pole, the red arrow from the new sub-Mars point, the green arrow from the anti-apex point:
Yup, I had my model in my hand as I was figuring it out! Yours seems to have been assembled more neatly than mine though
Any engineering problem can be solved with the abundant application of tape.
What's the orbital period on that massive iPod Jason?
I'm just starting a new Deimos mosaic for use in my atlas. I will post it here in a day or two. This is the Viking mosaic I made a decade ago, with the two MRO images added. They allow significant improvements in some areas, especially near the prime meridian and on the ridge that extends west along the equator from 0 longitude.

OK, here's a new Simple Cylindrical map of Deimos, mostly Viking but with the two MRO views added in.

Again using the Deimos map incorporating MRO images - here's a new map of Deimos in a different map projection from the cylindrical - this is designed to illustrate the shape of the body as well as the locations of surface features.

How do you go from the cylindrical map of Deimos to the two 'hemispheres' ? Here's a comparison showing an intermediate step, an azimuthal equidistant projection in two hemispheres.
