sol 2547 ( Mar 24, 2011 ) "stamp" panorama:

p-1N-2547-L0x2sqtv-stamp-3

Oppy has left the Santa Maria area.

It is now the early morning of sol 2549 and no new images have been posted on Exploratorium or the official MER site since sol 2545.

Here is the topic Santa Maria crater.

This is a water vapor zone. Why would I say this? In my best Hort impersonation, Er… Dry dust blows and makes ripples….. Damp dust don’t.

I would also like to mention that I though everyone was well behaved at the last stop. Hey, wait a minute, what happened to my lunch bag?

As always, nice image Hort.

sol 2549 ( Mar 27, 2011 ) "stamp" panorama in next drive direction:

Perhaps the plan is to visit the large 80 cm dark block about 8 meters distant?

Today's ( sol 2550 ) image descriptions don't look like a drive - but may have been a "bump" closer to the block.

It is now the night of sol 2550 and still no new images posted anywhere.

Looks like Exploratorium updates are back.

I will "catch up" a bit this evening.

Impact Breccia w/ possible melt surface this side OR a really big example of fracture fill OR maybe a combination of the two. Shocked

Nice rock image in #5. It seems to have similar texture to the dark rocks at Santa Maria.

Curvilinear "crack" in outcrop at middle near bottom; it does not look like a dessication crack. Also "staining" on the rocks near the bottom.

sol 2374 ( Sep 28, 2010 ) L2L5 "drive by" of meteorite Ireland:

The image in reply 7 is from the L7 filter of the drive by of the meteorite Ireland.

Only the L2 and L5 images were in the Analyst notebook. Note the weird offset in the picture. Also very strange that this image was posted 6 months after it was taken. I would have thought it was long ago deleted from Oppy's memory.

There was a 1 hour drive on sol 2551 and a 2 1/4 hour drive on sol 2552 towards the SSE.

No images posted anywhere yet ( including tracking thumbnails ) for either drive.

The target "bagua" ( the block in reply 5? ) was imaged with filters L257R257 before the sol 2551 drive.

Yep. Drive. Drive. Drive.

The rover track is very shallow here. It seems that the layer of soil that covers the plain near Santa Maria is uniformly very shallow, except for some thin widely spaced ripples (for example in the foreground above). Or could the soil here have somehow become very hard? Either way there is something to explain. If the soil is a uniform thin layer over rock, how did the thin layer form? Wind doesn't tend to distribute particles evenly on surfaces. Maybe dust settled from still air would be uniform in thickness but any movement involving dust, sand or granules in a wind tends to produce a very uneven distribution, that is, ripples or dunes. I think that another process must be imagined to explain the thin coating of soil in these areas. For example, a certain shallow thickness of soil could become chemically cemented to the rock by a process involving the diurnal microclimate under the soil, which would vary with the soil thickness.

We have seen thin soil coatings in a variety of places at Meridiani. Another example is the half-pipes at Erebus where the coatings are thin enough to show the shape of the underlying bedrock clearly but so continuous that the bedrock is entirely hidden from direct view:

Here is another example of apparent continuous thin soil coatings on bedrock from the Victoria ingress, this time on a slope:

This sort of thing is really common at Meridiani and unexplained. The wind-scour theory of erosion would have to imagine that these soil coatings are absent during the erosion process. I'm interested in the idea that erosion of the bright rock takes place chemically under the coatings. Again, the uniformity in the thickness of the soil coatings in itself implies that some sort of chemical process in involved.

sol 2553 ( Mar 31, 2011 ) after a two hour drive:

targets hershel, unalaska, greenland and boba were imaged with L257R257 before the drive.

Kye,

Dust fall from the atmospheric dust storms should be more uniform. The nature of this dust has been very apparent on the rover. It will arrange itself in an almost fabric display. You are correct in the fact that wind does pile sand and dust into dunes, unless cementation occurs first. Vapor emissions the source and thermal inertia the condenser.

sol 2553 ( Mar 31, 2011 ) "stamp" L2 3x1 in next drive direction ( east ):

Today ( sol 2554 ) is another driving day. That's 4 driving sols in a row. If this pace could be maintained ( it can't ) Oppy would be at Endurance by mid June!

Ahhhh. Looking back on Hort's image of the block and Ben's reply #6, I think explains things well. I always wondred where the breccias were. Ben, saying "impact melt", made me think. Remember the fields of dark cobbles? The ones they never bothered to look at closely. I think they may be impact melted material from small, long ago eroded away craters. What we are seeing around Santa Maria could be simply larger chunks of the same stuff.

sol 2554 ( Apr 1, 2011 ) after 120+ meter drive:

as determined from the sol 2554 map.

Perhaps the small increase in the right front wheel current that was reported in the sol 2546-2553 status report is due to the soil and rocks rolling around in the wheel:

No drive planned for today ( sol 2555 ). A couple of looks at the right front wheel and downlink of some of the science images of the last few weeks?
