It's hard to tell from this distance whether the layering in the central mound is from algorimancer's remnant "beaches" or is from centsworth's layered Meridiani sediments, though my money's on the latter. That could still be analogous to the Gale mound, if you imagine the Meridiani sediments being stripped away from the entire landscape except inside the crater. But maybe the albedo features in the bottom of the trough could be the remnants of a dried-up lake??
There's years of work to do here... John |

. I've all ways wondered if Mars does have any rare metals? Mars has a fair number of iron meteorites laying around, so there is a fairly decent source of platinum group metals (platinum, palladium, iridium, etc.) You're not going to spot any gold or silver from orbit, save perhaps the very rare gamma signal from an atom getting zapped, and certainly not enough data from those to build you a distribution map. |

My opinion (a two cent value!) is that the mound is the same built up sulphate layers that surround Endeavour and cover all of Meridiani that Opportunity has traversed. I wonder If layering has been noted, from orbital images, in Endeavour's; or any other pre-Meridiani crater with an interior mound? If not:Perhaps confirmation of you opinion, about both the layering and the material of the central mound, would be one more significant achievement of this mission to Endeavour. |

John Just wish that you are right and that Oppy will survive to give us those years for future work and discovery!! |

Never bet against a Mars rover, or the amazing people who keep them going back here on Terra.
I mean... just look at how far Oppy has actually driven, compared to how far it was hoped she would drive at the start of her mission... ( from: http://roadtoendeavour.wordpress.com/2011/...ng-for-landfall ) -------------------- |

Now that Opportunity is back in full science mode and in a target rich environment, it will take years for her to add the required 5 miles (8km) to complete a 26 mile marathon.

<out of my league warning> is it possible that the mounded center is a result of rebound uplift from the impact? </out of my league warning>

In a word, no. The mound is much too big relative to the crater to be an impact-related "central peak" due to rebound, and in the north it's continuous with the Meridiani plains outside the crater.

I'm curious to see crism data of the interior of endeavour crater...is there a link?

Thanks for the comments on the colorization of panorama's.
I must admit that the word color is not the right one, it must be colorization. It's an artistic impression of the colors on Mars. ( DFortes, Walfy ) You like Rembrandt or not, You like van Gogh or not, You like Picasso or not, to name a few. I have never stated this are the True colors on Mars. The sole purpose is for better and enjoyable viewing. ( DJEllison ) Others make polar views and others do vertikal stretching, also for better viewing. For Toma B It are colorized L2 images from Exploratorium. The L5 and L7 images where not published at that moment. Let us be happy that so many people follow Spirit and Opportunity on Mars and use the images. Thanks to Steve Squyres etc. who made this possible. Jan van Driel |

Whats the record for the russian rover on the moon? 35km?? Lunokhod 2: 37 km. Oppy: 33,2 km 3rd August http://en.wikipedia.org/wiki/Lunokhod_2 Maybe Oppy will get also this record. I think they will do much analysis on different parts of Cape York, and then go south to find more at Cape Trib. It is about 5 km away, so more than 37 km would be possible and also scientifically useful. From MER Update of 30th June: http://planetary.org/image/Endeavour_rim_map.jpg "Cape York is nearly surrounded by exposures of hydrated bedrock. From there, the planned exploration route goes south along the rim fragment Solander Point, to Cape Tribulation, where clay minerals have been detected. " This map CRISM Map Cape Trib is from cape Trib and Cape Byron in the south, which requires at least 2 km more driving. So the odometer could be here at 40 km. I think searching the right places, analysing them with the spectroscopes will be very time consuming. Just expect years of exploration ... -------------------- Need more input ...

It's an artistic impression of the colors on Mars. ( DFortes, Walfy ) You like Rembrandt or not, You like van Gogh or not, You like Picasso or not, to name a few. Yes I like some of those artist and dislike some, but I don't see them as ART. Whats the point of ading sepia tone to every image and then calling it colorisation? If you see some artistic value in doing that, thats OK with me... For Toma B It are colorized L2 images from Exploratorium. The L5 and L7 images where not published at that moment. Now I checked again and it is PERFECT FIT. Both of those Ant103 images are from SAME sequence and are L257. THEY WERE ON THE GROUND much before Ant103's posted his version (Post #1450). Look at this same thread Post #1411 by James Sorenson and Post #1414 by Stu. Only diference is prefered Color Levels. Oh, and BTW I actually LIKE those L257 cororisations. Reason why they DO LOOK sometimes unnaturaly yellow or red (or whatever) is because of diferent tipes of monitors and video settings that we use. -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

You're reducing the available detail in tinting it so vividly orange, so quite how it can be 'better' I don't know. Hi Doug, If I may offer a thought here.... I suspect your difference of opinion and interpretive value regarding the tinted imagery Jan produces may be more akin to the differences you and Stu have at times, such anthropomorphizing the rovers vs not (does Oppy's heart glow, or is it's WEB just emitting greater in the LWIR than it's surroundings). I suspect that Jan and others enjoyment of the tinted imagery, their consideration of it as an improvement, lies in the atmosphere, mood, or even sense of place the color evokes. On the other hand I, along with yourself and at least Toma B prefer the the imagery to be as accurate and full a representation of the actual data, the scene as sensed, as possible. Consequently, the heavy tinting is a burdensome obfuscation of the data, a hindrance to the analytical enjoyment of the data in it's fullness (at lease as far as the stretched jpgs allow anyway). Aesthetics vs analytics. Maybe I'm stating the obvious. Anyway, that is my two cents in hope of easing the discussion a little. -- Pertinax |
