I think it's time for a new thread for Opportunity after her Block Island Studies and time to think about where
the Mars Rover Drivers are going to send Her. Will they decide to head south of Block Island or go back
to the western route they were on before?
Where ever they go. I hope they find some more interesting surprises along the way.
One Question I do have regarding the Rovers. Have they ever found any Diamonds or Gold along the way
and if mars did have them. Would they be buried beneath the surface??? Something I've been wondering
about for a while if any precious metals would be on Mars or Not? I would say yes.
Time to start

Actually she is. Opportunity left the area today, sol 2004, with a 70m drive; first N and then NW in the general direction of the previous western path.
We're on the road again!

Ah, I'd missed that. My apologies, Bobby; I honestly thought we'd spend a couple of sols looking at the bits of darker material scattered around BI. Well... Onwards it is then!

I'll second that. The wheel tracks from the out and inbound legs are clearly visible on the mosaic.
Today is another driving sol. My take is that we'll catch that path and continue WNW until the same or similar point as during sol 1950, stopping for a quick science stop at those two craters Kaiko and Dolphin/Nereus.
Incidentally, I'm not really sure about the name of that second crater. The name "Dolphin" comes from the sequence used to shot the crater's pancam mosaic during sol 1950. However, it is named as "Nereus" on the monthly report from July. I'm tempted to take the second one as the correct one but it would be great if someone could confirm it.

Regarding the color panoramic in Ant's post 25, what causes the dark marks along the path? Does the rover stop at regular intervals during a drive? How does that work with the auto-nav update?
Apologies as I presume this has been answered, but my searches don't lead me to it.

The marks come from the wheels' surface which is not uniform. Let's see if I can find a picture...

This picture is probably a good example. Each wheel's tread pattern contains what has sometimes been called a "star pattern." It occurs once on each wheel's circumference and serves to punctuate what would otherwise be monotonous and mostly featureless tracks in the soil. The patterns create repetitive features in the rover's wheel tracks that are useful for auto-navigation and other functions.

The star patttern isn't there for fun though, it's where the wheels were bolted down onto the lander deck for launch, cruise and landing.

Interesting rocks - so here's a b/w stitch of 4 left pancam images Sol 2010. Enhanced the originals to bring out as much detail as I could, although posted here at 15% below full res to get under the 1 Meg limit.
They've all been taken through basically the same filter (754/3nm - red) - so haven't gone beyond black and white. Hope jpegs taken through other filters are available soon as this set would be good fun to make a colour pic out of.

Hmmm... not only are there two specific types of rocks in the B&W images, one appearing white and the other appearing darker gray, there are several rocks in the image which show both rock types within the same rock. You can see in several rocks a contact between the light and darker rock types. And in a couple of cases, the faces are oriented exactly the same on both sides of the contact, so this can't just be an artifact of illumination angle.
I will say that there seems to be absolutely no difference in how the two different types of rocks have weathered -- i.e., those rocks which exhibit contacts don't exhibit weathering differences on the different sides of the contacts. So, whatever is causing the albedo difference is not changing the overall softness of the rocks.
I'd have to think this shows some form of compositional change. This is the first place in a while where I wish the APXS and the Mossbauer were still working as quickly as they did a couple of years ago...

You've made an interesting point Doug. It was this sort of rock that made me think that the whiteness was probably due to an artifact of camera exposure or illumination. (Plus I only know a very little about geology!)

It is certainly an interesting place. It would have been great to stop, but having just been to Teishner's lastest map, it looks as if Sol 2011 may have taken us past here.
Juramike
Sep 20 2009, 11:51 PM
I'm not sure, but I strongly suspect it might be an effect of sun angle glinting off flat surfaces of the rock.
(The shadows indicate we are looking close to the direction of the sun.)
It'd be neat if there were observations done at a different time....(are there?)

I don't see any difference other than angle of illumination. if it was indeed a compositional change then it should be evident in the side of the rock closest to us.

I can personally vouch for the fact that the 3rd anniversary card enjoys pride of place in the middle of the table in one of the Ops rooms in Cornell.
And many of you will like this - overheard during last Monday's Opportunity SOWG: "Drive, baby, drive!".
All systems normal (including that one wheel's motor current) except for the mini-TESS' still present dust layer of course. They will leave the aperture open and hope to just get lucky one day with the wind coming from *just* the right direction to blow at least some of the dust off the mirror. Batteries also in great shape still.
Expect plenty more Westward travel before turning South, but that is not a surprise of course.

Agree completely, and congratulations to the posters of the panoramas. "Berry nice" views of abundant spherules in the dug-up boulders! As usual, but not usually so clearly seen in images, the spherules are strictly size limited, not clumped together, and occur along (are apparently controlled by) bedding planes. Well worth a closer look, because these features are NOT typical of sedimentary concretions.
