I was actually wondering about this image the other day. It definitely came from LORRI and it is in the Photojournal but the source image(s) aren't on the SOC at all unless I missed them? Have I misunderstood that all LORRI images would be uploaded to SOC as they come in or is it just 'most'?

IIRC This one was delayed a couple of weeks, I think they just missed it when updating the site.

What I remember is the images posted on Friday are those downloaded by the end of the previous Tuesday, seeing that the photojurnal image was posted two Tuesdays ago I was expecting it to be included in last weeks update.

I've pointed out that it is missing from the LORRI site via their feedback link, perhaps it will show up next Friday.

I'm thinking that the definitive release of the NH data won't be until PDS-time and this is just the preliminary iamege release, for which we should all be thankful to the NH Team.

That image ( PIA20155: Ice Volcanoes on Pluto? ) being from LORRI is a bit puzzling to me. It appears to have been taken 'straight on', but I would expect the field of view to be much smaller (closer) when NH was at that position. It could be an image taken earlier that was stretched (perhaps one that has already been released), but there appears to be no artifacts indicating that.
ZLD
When I was working on the tweened animation, I noticed that it didn't appear to be projected quite the same as the MVIC scan, so I think you're right in suggesting it has been reprojected. However, it seems far too high resolution to be from data we already have publicly available.
JohnVV
PIA20155 not really sure that it is reprojected , but it is on the limb so there is some curvature
-- shadow lengths change more than just a bit

but this one dose work a bit better than the last one
-- i ignored the fact it is curved and on the limb .The mesh is mostly flat



Bill Harris
I wonder if it could be an illustration based on several images rather than an actual image?

NH is now more than 1 AU from Pluto!

Double header!
stfletch
Since things are quiet at the moment before the double header release of LORRI images coming up on Friday, I'll post an updated version of my list showing what we have received so far.

Not too many updates as a lot of the LORRI images released over the last few weeks have come from before or after the time period covered by my list.

See caveats in THIS post.

ZLD
Thanks for the continued updates stfletch. These have been a great resource for referencing the data.

Catching almost every major type of terrain in one long strip! Thanks Pluto!
Now where's that swear jar....

Amazing! A bit in particular that interests me is the way the snow slumps in this bit of the image. Are those snow 'dunes'?

It begins.

Are those haze layers or imaging artifacts, particularly the dark zone on the right?

Probably an image artifact. I remember seeing stuff like that at Io.

Here's my rendition of the P_MVIC_LORRI_CA mosaic. Still missing 4 frames it looks like (plus the rest of the frames approaching the terminator, of course), so there are a couple of gaps.

(EDIT: I've uploaded a new version. saw there was one more image posted from this mosaic, so there seems to be only 2 frames in a gap there, the other gap had only one and has been filled)

Incredible views.

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

It seems evident that glaciers are slowly transporting material from the higher terrain onto the icy plains slowly eroding the rough mountain terrain.

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. smile.gif

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:

Do the two strips (mine and Herobrine's) overlap at all?

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.
Gladstoner
From south to north, there appears to be a progression/evolution of the 'cells' (left to right, top to bottom):

Click to view attachment

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 )

The sharpness of that boundary is striking. I can't help thinking of oceanic crust subducting beneath a continental margin.

And that image of the mountain--ice plain boundary is amazing. The debris fans from the mass-wasting of the mountain blocks are clearly resting on top the ice of the plain and this speaks volumes about relative ages of these units and their history. I shudder to think about higher resolution imagery on Charon, my choice of study.

And, thanks again to the NH Team for sharing this.

The stuff between the blocks and along the margins seems more like floating flotsam being constrained by 'currents', kind of like this:

What would mass wasting look like when involving the various ices on Pluto? It may not resemble what we see in much of the solar system.

Well, it's not just mass wasting, but mass redeposition. Bizarre think to consider,
pluto has 2 conflicting forces- global heat flow and atmospheric heat buffering.
IIRC, at pluto's conditions, H2O ice conducts heat significantly better than N2 ices.
But, because pluto's atmosphere is N2 and it has large areas of N2 ice, they are in equilibrium, and
the surface should be like a giant constant temperature bath.
So, just like a pitcher with many ice cubes slowly turns into a pitcher with one giant ice cube,
the mass will not just waste, but redistribute.

Wow, several interesting things about the convection cell images, and the paper.

First, the assumption that the N2 ice is going through the A-B phase transition.
That should essentially shatter the bulk ice into small grains which are then small enough to convect.
It appears that small grain size is a prequestite for bulk convection.
http://www.researchgate.net/publication/25...LUTO_AND_TRITON


Another thing, convection is generally better than conduction at moving heat. Convection should actually concentrate the
heat flow towards the center of the convection cells. Perhaps the pits are a result of that locally increased heat flow.

Flip side, the subducting edges of a convection cell will have less heat flow than adjoining conduction areas.
So, the 'cold' subducting edge of the cell should pull heat out of adjoining area, perhaps that why CO ice is there.

It would be alien and otherworldly. Terrestrial analogs may not hold up but they are about the only template we have now. See what fits, then modify to conform with reality.

Good analogy. WaterIce-ite has an SG of 0.927 and Nitrogen an SG of 1.026 so the debris might tend to be somewhat "floaty". We see some debris collected in the downwelling "subduction zones" between convecting cells Remember the physics experiment where a block of dry ice could float frictionlessly on a tabletop, supported by a film of sublimating CO2? A chunk of water-ice may behave frictionlessly on a surface of N2 ice. And remember the "racetrack boulders" on Western US playas that R.Lorentz studied a few years ago.


QUOTE (HSchirmer)

And very good points to consider. The surface of Pluto could be considered to be balanced in a precarious state of equilibrium. Even insolation, which has a very small energy input, has to be considered in the thermodynamics equation.

I'm waiting for someone to look at The Hubble imagery of Pluto and make a quesstimate of the conditions on Pluto backtracked from today's conditions over the last 25 years (10%, 1/10 of Pluto's orbital period).
I found a press-release montage with 2002-2003 imagery at longitude increments of 30deg which provides an overview:

http://hubblesite.org/newscenter/archive/r...010/06/image/h/

And conditions on Pluto and Charon are not dissimilar to thousands of other Kuiper objects so this is more the rule than the exception in our Solar System.


There. No arm-waving, my hands were carefully folded in my lap... wink.gif
