The latest navcams make this circular view.

From Maxwell:
QUOTE The scientists spotted something shiny, so we have to stop to IDD it. Friday... might be just a short "bump" or IDD work. Allright, who can spot the shiny thing? |

I asked Scott. He meant "shiny" as in the Firefly-lingo for "Cool and interesting", not literally shiny as in "meteorite"...

OK, who can spot the "cool and interesting" thing?

Do the experts out there see what might be festoons?

Lots of rocks and crud up ahead, including at least one big block, I think...

Another Nav Cam challenge from Sol 2393 - 17 Oct 2010. Should have gone to bed a couple of hours ago!! Too addictive.

fredk: The last time I cried wolf I ended up having to eat my words, so I am still a bit gun-shy regarding those things. But, I see what you are talking about. I'd like to have some pancams before committing. Let's wait to see what pancam_puntarenas_L257R2 and navcam_3x1_az_225_el_neg45_3bpp_crit look like tosol.

The current IDD work volume is visible in these haz, nav, and pancam views:

So maybe the interesting feature is that darker smooth band along the edge of the block? It looks like a slightly lower layer of the block. I don't recall seeing this before, but maybe a look back would uncover more of them.

That could be it, Phil. There's also some slightly darker rind on the bedrock at the bottom of the pancam frame. I also don't know how common that is.

I didn't notice the rind, but you're right, that could be it as well.

It almost appears as if while the sulfate rich mud was descicating and shrinking (leading to the mud cracks) the top centimeter or so of this particular section got caught on one end and slid relative to the mud underneath. This left the strange "darker smooth band" texture that you see along the top edge of the section where you are looking at the now exposed lower strata. You can also see how the top sheet pulled away from the blueberry rich soil. In support of this theory, there is a mud crack between the section that slid and the section to the left. The crack had a slight zig-zag and now you can see where the point and the corresponding recession on the opposite side have shifted relative to each other. Notice that the shift between the point and the opposite recession is the same as the apparent shift of the whole top 1 cm of the section relative to the edge of blueberry rich soil.
I think I have seen similar things happen in terrestrial mud cracking where a crusty, thin, top layer shifts horizontally as it shrinks relative to moister lower mud. Any possibility a similar thing happened here? http://qt.exploratorium.edu/mars/opportuni...2M1.JPG?sol2397 |
