Very cool. Nicely done smile.gif Are long baseline pics of the west rim (where Oppy's heading) available?

Thanks! The west rim wasn't imaged well until just recently. It was visible from Victoria, but only just: you can see it barely peeking over the horizon in this pancam view:

So I don't think we can get much of a long-baseline view of the west rim yet. After we move another couple of km south we should be able to put together a nice anaglyph.

"Kasos" does not appear to be a meteorite in the latest MI views:

http://nasa.exploratorium.edu/mars/opportu...E0P2996M2M1.JPG

"Kasos" looks like typical Meridianni bedrock stuffed full of blueberries. I wonder if there is now any point in using the IDD "Kasos". I think that Geologists normally like to sample bedrock in context and in situ. Perhaps the pavement adjacent to "Kasos" would make a better IDD target? Of course I suppose that it is possible that "Kasos" originated from deep within Endurance crater and so is a sample of a completely different level within the stack of Meridiani sediments.

EDIT: Here is a useful link I was sent, which reminded me how to check the dates from the rover image file names:

That's not Kasos - that's old data getting downlinked. That image was taken Mid-March.

I thought I'd have another go at the MI shot that Oppy took of her LF wheel using a neat bit of deconvolution software for CS2.
Just starting to learn how to tweak it, but the first result is interesting and I think that there's a lot more to pull out from it.

Original left, deconvoluted right.

This has been reduced in scale a bit for file size convenience and I've yet to play with the shadows part of the new plug-in.
It will be interesting to see the results achieveable if Spirit takes any shots looking under the WEB using her MI.

Q: what about the RF wheel current during the drive on sol 1884?

I have been told they are back to normal.

I've seen some "drive direction" pancam shots on the last downlink so preparation for the next drive (a looong one, I hope) should be ongoing.
However, I see that the mossbauer is being (or will be) used too and given its current integration times, it means we should be parked at this spot not only during the weekend. Let's see.

It appears that the MIs of Kasos have come down. The pancam IR filters have shown its mineralogy to be quite different from that of the native bedrock. In the MIs, it appears to be a coarsely-grained, crystalline rock. I wish it was a large enough cobble to grind with the RAT. Might it be brecciated?

It may well be my faulty memory, but "Kasos" seems like something new? Here's a crude 4-image MI mosaic.

A bit late - not much spare time being a parent to a three month old! - but here are the colour (R21) drive direction mosaics from a couple of weeks back.





Unfortunately the recent drive direction pans haven't been taken with multiple filters so no colour I'm afraid.

"Kasos" is kind of shiny; fusion crust? Stony meteorite?
