Gale Crater Has Many Faces- Curiosity in Progress

Many faces to rocks, many history stories to tell.

Watching the Curiosity MSL progress and giving the HiRISE Gale crater images a close study is revealing an artwork and a labor for science understanding. What an unexpected intrigue with twists and turns in the road to science from simple observations.

The Grand Canyon of Gale,,,,plus a bit of everything else,
I don't seem to notice near as many impact craters,in Gale.
It has been said that Gale is a ?young? crater?
Ice?,,,,,,,I know there is some somewhere in Gale.
Thanks for all the info Dana,I don't get much MRB time,,,lately.

,,,,,,,and when I DO post,,,I seem to stop threads
dead in their tracks,,,,,or is this just my perception,,?
Remember this about the internet.
When it is written it is recorded.There is no "No I did not say that"
Gale mysterious faces of Gale.Good name.

JHD, by SHARAD data there are massive ice deposits in the middle latitudes of Mars just below the surface.
No such deposits in the equatorial regions detected as of now.
Anyways, I suspect most ice/water in Gale crater to be 1) blasted away by the Gale impact. With a little of it flowing back in from the crater rim (nice little channels observed there now and given a quite static environment) 2) molten and evaporated by the residue heat of the impact.

I even suspect the few clay deposits observed at the base of the mound to came into being due to short lived (geologic) interaction of meltwater and the impact rubble. That would be the worst case in terms of habitability but would explain the lack of larger clay deposits in Gale crater. :confused:
There maybe larger volumes of clay as well as carbonate outcrops perhaps beneath the dust layer but that is worthless for the MSL mission to find out about historic habitability as it got no ability to dig. Yet i read somewhere they are going to use the blocked wheel method to dig shallow trenches just like Spirit - way adress this problem. :-)

Yes I still dont really like Gale crater but we all will have to wait for MSL to arrive there in a year.
If its going to be a boring landings site in terms of science (astrobiology) we will at least get some nice footage from James Cameron (even in the case the MSL fails to land on its jetpacks/skycrane maybe?).

This topic is still hidden away in the Against The Mainstream sub-page, and cannot be seen by routine readers of the blog. This is apparently a punishment sector where the astrobiology group were to rot over the years. An open astrobiology section open to the public would have been far preferred, as popularity is the determining factor in blog posting and reading in other topics once the public has access to section topics listed on the main blog entry(home) page.
My first viewing of these hundred or more Gale crater images, was a manual attempt to view the highlights and mid-tones in in high textural definition, and I found it was necessary to let the shadows 'drop out'(go to black). The result in a run down the very first image far right side, was face after face, of strange alien appearances, or caricature cartoon faces. Something in the materials of Gale crater has given us a recognition factor in erosion, impacts, and original masses. Now after viewing a half dozen low lying MSL landing ellipse area images at normal settings, I also have found the many spots where the bright smaller dune ripples attach to the solid rock layer 3D linear shapes. Another factor of materials as strange as any cartoonish faces we might find while looking for evidence of former life and any unusual geology items. I posted those images in the 'Gale Crater' topic now seen on the home page, and as John Henry Dough has suggested of his posts, the replies have 'dried up' temporarily. Perhaps persons find mysteries in science to be uncomfortable. Science consists both of that which we understand, and, that which we do not yet understand, and by definition, science stands alone as a potentially all inclusive method of resolving the matter of ignorance and lack of testing the material world.
Solving the problem of 'mass wasting' on Mars even in the areas where the bright small dune ripples maintain integrity and pattern is one of hundreds of science problems being solved in this blog and elsewhere.
Presenting a valid information case is one of the first steps. Finding repeat examples is another. Discussing the possible actions and processes, and connecting the cause and effect patterns is yet another. Finding our blindness and omissions is important. There are times when the only solution is to design a tool for further evidence obtainment.
Hopefully the MSL can give us additional details in the puzzle of Mars long record, while testing new equipment on forbidding terrain slopes. Hunting for groundwater effects in dated layers seems to be an important current goal in selecting such a large mountain to climb.

My request for this topic title to be transfered to the entry 'index' page of the marsroverblog has not been responded to, and I will now restart the topic in the Mars Biology section, attempting to place the biological possibilities at Gale crater into the public view.

Thanks for the patience. You will have to begin anew. A common problem of biology content everywhere.

An interesting link for those seeking a better understanding of the possible spheroidalism-biology connectedness which may be shown someday in future years as applied to the Mars history.
HydroxyApatite ( HA ) as a product of hydrothermal processes forming spheroidal units which are stand-alone look-alikes for our Mars 'blueberries'. The very texture, organization internally, and the size, are a near match. Image at the bottom of the linked research page.
Having found the mineral Apatite/Calcite(a micro crystal) in the Mars soil, I am confident that further contribution of that mineral group will be confirmed in later testing, either by rovers, or by manned mission landings.
The dominance of iron in results does not preclude other mineral content at the formation source for at least some of the spheroids, and a portion of the mixtures. The calcium suite has not been admited to as yet in the MER tests, despite the appearances of Calcium based minerals, and the large figure for Calcium in instrument readings was not discussed publically. Phosphates was not discussed in 'media' releases at NASA and other groups additionally.
Lets keep our heads high for more than one mineral group to be attributed in the Martian soil mix, in the final count.
