How far down into Endurance Crater do you think Opportunity will eventually travel? Right to the bottom?

I doubt it. They're not interested in the sandy stuff at the bottom, but the layers out closer to the edge that they're investigating now. And if they get onto sandy stuff, odds are they won't be able to get off again.

What??? :evil: I WANT TO KNOW WHAT IT IIIIIIS!!!!! :evil:

Its color is TOO strange, I can't believe it's just sand. But I'll not know until we'll dig it! :evil:

I would expect that the sandy stuff in the crater isn't that much different from sandy stuff outside the crater, since it's all getting blown around anyway. Presumably they can get some idea of its makeup from the pancam and mini-TES data, and we would have heard if it were anything amazing.

Ok, I'll tell you: I really think we are seeing just a dust layer... covering snow or ice! 8-[ :-s

It's time to look up from the fascinating floor of Endurance crater and enjoy the clouds (http://marsrovers.jpl.nasa.gov/gallery/all/1/n/153/1N141754902EFF3200P1554L0M1.HTML)!

Or maybe it is melted material from the impactor? 8-[

I was wondering why the sand at the bottom of Endurance was so differently colored, but now I just realized it's probably just blueberries sitting atop the dunes.

Steve Squyres is interviewed about the findings and plans for Endurance Crater:

Investigating Endurance Crater (http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid= 1063&mode=thread&order=0&thold=0)


It's starting to look like we can go as far as we want and be able to climb back out. That remains to be seen. We're on a 25-plus-degree slope and just yesterday we went over a step about half a meter (a foot and a half) high that was at more than a 35-degree angle, and we climbed back up over it just to see if we could. And we did.

These vehicles have remarkable climbing capability. So we're going to proceed down this section at Karatepe until either we get to some topographic point of no return, which frankly may not exist - the vehicle climbing capability may be so good it's just not an issue - or until we run out of intact stratigraphy. If we get deep enough and we find out that we're just into a jumble of rocks that are not in place any more, then there's no point in treating it like stratigraphy, because it isn't. At that point, we have to start looking at other things that we should do, because you're always prioritizing science, and there are some very important high-priority science objectives out on the plains.

The observations at the large Endurance Crater indicate that the elements making up the shallow rock layers resemble those of Eagle (where the rover originally came to rest), while the deeper layers of Endurance possess increasingly higher concentrations of the element chlorine. Sulfur content, one key salt-bound element, has proven about the same between the two crater's exposed histories. When Cornell Principal Investigator, Steve Squyres, first encountered such high sulfur and sulfate proportions inside Eagle Crater, he wrote in his mission diary: "There's so much sulfur that we think there has to be a lot of some kind of sulfate salt in the rock, which is very hard to account for unless water was involved."

Still finding "blueberries":

Dining on Diamonds (http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid= 1120&mode=thread&order=0&thold=0)


To continue this line of investigation, a crucial excursion was to see if this finding was widespread or local. The rover team pointed Opportunity to the nearest large crater, Endurance, and what they have found is more evidence of the strange blueberries. As they have driven the rover down the crater walls, Mars has yielded up new examples of concretions or 'blueberries'. Even after many months of seeing these spherules, the latest microscopic images have the same startling effect first experienced in mid-February when Squyres wrote "Weird".

the same startling effect first experienced in mid-February when Squyres wrote "Weird".Even more so, now that we've seen blueberries embedded in several different layers of rock, with presumably different composition and pemiabilities, and the berries are all still about the same size!
