Speaking of yellow bricks, when was the last time Oppy made an extended stop to give the bedrock a good, hard squint? I'm not trying to call it, or anything, but it almost feels like we're overdue.

This sounds a whole lot like the pedestal theory when there clearly was not one at BI. If such toppling over billions of years was so significant, why aren't there any pedestals underneath any of the pieces of meteorites?


Yes there was, though it wasn't anything to write home about:

Here ya go...

Personally I suspect they are all small meteorites, and each and every one should be thoroughly examined and photographed for at least a week. smile.gif

( That would delay your Endeavour arrival date to sometime in 2104 usarax, sorry! )

Just NAMING all those critters would take till the 22nd Century. If they are meteorites, I move that we call them the "Philippine Archipelago" & be done with it! tongue.gif

Actually, is this something new? I'd characterize it as gravel.

It resembles the shore of an island. It makes me wonder if this cobble plateau is a relative high spot or low spot on the terrain -- something to interrupt the regular ebb and flow of the dunes. I could see small meteorites riding on and in dunes over the millennium and being dropped in places where the wind currents or underlying terrain interrupts the uniform dune migration.

No, not new.

This was just south of Beagle crater in July 2006. At the time some people suggested it might be a clod of crater ejecta.

Ah. Thanks, Phil!

There's a relatively fresh-looking hit just to the east of here; maybe that's the source.

Yep. We've seen several examples of these piles in various stages of exposure. This one is partially buried by more recent drifts, I'd guess.

I have time... laugh.gif

Curiosity here, we are seing not only Endeavour but also Iazu on the western horizon, since we are heading south now will Opportunity have the chance of catching a glimpse of the rim of the monstruous crater on the bottom left of this image?:

What I mean is that, due to the distance, height, rover position, weather, will it be possible? btw, does that crater have a name? smile.gif

Is Endeavor in that image? Can someone highlight it for context?
