The best two Nix images oriented as i understand it.

This might make Nix the most densely cratered terrain that we've seen on any world farther out than Saturn? Potentially interesting for establishing cratering rates.

Since more than one satellite of Pluto is thought to be a merger of two bodies, or possibly more. So at some point there might also have been a lot of smaller pieces flying around, in view of that I find the cratering of Nix to be more or less what to expect.

On several of the latest images quoted "Kerberos" there is another body seen below it :

Another Pluto satellite ? Just a bright star ? smile.gif

I blew up the other body in the two images you mentioned and these are what came up.

Hydra's icy surface

QUOTE
The new data – known as infrared spectra – show the unmistakable signature of crystalline water ice: a broad absorption from 1.50 to 1.60 microns and a narrower water-ice spectral feature at 1.65 microns. The Hydra spectrum is similar to that of Pluto’s largest moon, Charon, which is also dominated by crystalline water ice. But Hydra’s water-ice absorption bands are even deeper than Charon’s, suggesting that ice grains on Hydra’s surface are larger or reflect more light at certain angles than the grains on Charon.

This animation is based on two images of Nix and generated using morphing technology.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

This is awesome, especially when one keeps in mind that it is generated from only two images (looking at it without knowing I would have guessed it was generated from a greater number of images).

QUOTE
During a previous epoch where Charon migrated away from Pluto, the minor satellites could have been trapped in orbital mean motion inclination resonances. An outward migrating Charon induces large variations in Nix and Styx's obliquities. The cause is a commensurability between the mean motion resonance frequency and the spin precession rate of the spinning body. As the minor satellites are near mean motion resonances, this mechanism could have lifted the obliquities of all four minor satellites. If so the high obliquities of Pluto and Charon's minor satellites imply that this system experienced orbital migration and all satellites were at one time captured into mean motion resonances.
