This interesting detail should help sort out the nature of the pits:

Incredible views.
Gladstoner, do you have a context view for that close-up? Agreed that it may prove indicative. -------------------- 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.

Yet another batch of impressive images. Pluto continues to surprise - I'm having a hard time remembering something of significance from the NH images that is *not* surprising compared to what was expected before the flyby. These images look to me like a weird mix of Europa, Enceladus, Mars, Earth (!) - plus features unique to Pluto.

I did a different section of the strip than the one posted in Photojournal today.
Here's a small version that fits the upload limit.
And here's the full-size version (1054x5391, 4.2 MiB) Here's a little context image showing the location of the strip section.

Indeed these images are stunning.
I spent most time looking at the boundary between the terrain types, where the rugged terrain appear to be resting on top.  Full size |

Thanks for the close up.
(Reminiscent of colonies of bacteria in microscopic views!  )No clear idea to what I see! Topographic data may be helpful. |

Some strangely circular features on Sputnik (from the official mosaic):
 The biggest one is clearly visible in the global colour mosaic as well, but I didn't notice it until now. -------------------- |

Faaaantastic new images! Perhaps it will be possible to use colour data from the big global view to overlay on these new mosaics.
By the way, the newly published "strip" extends further down than shown. Here's my ICE mosaic, going as far up as the edge of the mountains:
Zoomable version at photosynth: http://photosynth.net/view.aspx?cid=da9dc7...0d-ac8c9a1cef67 So, someone with enough patience could stitch the whole strip together. ;-) Do the two strips (mine and Herobrine's) overlap at all? -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

I agree, it look very much like the terrestrial counterpart that I've seen so many times. Though the material is ofc very different here. |

Form the AGU abstracts:
Pluto's Polygonal Terrain Places Lower Limit on Planetary Heat Flow QUOTE Our model implies a core temperature of 44 K in the interior of the convecting layer. This is very close to the exothermic β-α phase transition in nitrogen ice at 35.6 K (for pure N2 ice; dissolved CO can increase this, depending on its concentration), suggesting that the warm cores of the rising convective cells may be β phase, whereas the cooler sinking limbs may be α phase. This transition may thus be observable due to the large difference in their spectral signature. Perhaps the pits are the result of this phase transition. |

From south to north, there appears to be a progression/evolution of the 'cells' (left to right, top to bottom):
At first, they appear to poke out from the plain. Smooth surfaces develop around the cells and then seem to shrink into the prominent linear features as the cells grow and merge together. Eventually, the lineaments seem to shrink further into thin, dark lines that are seen near the Al-Idrisi mountains. |

not too many areas on Pluto lend them selves to SFS
the ones that do are a bit visually boring ( scientifically FASCINATING ) from "lor_0299179742_0x636_sci_2.jpg"
