The green pixels are in the original image you refered to. Nothing odd about that, though - you can see pixels of various colours in many of the supposedly monochrome jpl jpegs when you crank the gamma up. The reason is that they are not saved as genuine monochrome (8bit) images. The jpeg compression algorithm doesn't get the hues exactly right, which means you get hues other than grey, ie various colours.

It's always annoyed me a bit, since the filesize would be a bit smaller if they were saved as 8bit monochrome instead of 24bit colour. Also, as we see here, when you do severe tweaking of images you usually start to see these coloured artifacts, usually in the dark shadowed areas.

Were we not expecting any activity today, it seems only images from yesterday came down?

EGD And just why do we need to "...be REALLLLLLLL careful with this discussion"? Didn't seem to me to be verging on little green men or anything antiscientific. Fredk gave a great explanition.

He wasn't saying you were being like that - but that it is very easy for such a discussion to go that way.

This was posted on Twitter earlier

I have the impression we are just starting "restricted sols". Can someone confirm / disregard it?
And about further activity, Scott Maxwell twitted: "On Opportunity today: driving ~10m toward "Marquette Island" rock, setting up for fine approach (for IDD work) Monday.".

Thanks for the enlightning explanation fredk!

I can understand Floyd, with all the work you have done to keep this room as aseptic as possible I don't see no need for Dan to issue such a warning since the question required specifically a technical help which fredk provided pronto and clearly. We're not kids anymore you know?...
Dan...you are spending to much time with that mower of yours...

So...are we going to seat here for the whole weekend?...

My first impression of Marquette Island is that it is fairly brittle ejecta block from some other cratering event.
The final shape is reminiscent of a shock cone. The surrounding stones and cobbles were probably shed on final impact.
There appears to be multiple impact sites in the immediate neighborhood. This may mean possible multiple other ejecta that followed the same trajectory or this rock really bounced around and broke up. If so, it may be from deep underground and bears study... OR ... its just another weird kind of meteorite! This week's studies will tell...



Your mileage may vary...
Cheers

And indeed, a meteorite IS ejecta, albeit from another body in the solar system . . .

Ladies and gentlemen... Marquette Island...

Can't wait to get closer to this beauty...



Reminds me a little of a dark version of "Wopmay", the 'dinosaur brain' rock Oppy saw back in Endurance...

What happened with yesterdays drive?

Yesterday was not a driving sol. If the question comes because of Scott Maxwell's twitter message, just say that I read it as: "On Opportunity today: sequencing a drive ~10m toward "Marquette Island" rock, setting up for fine approach (for IDD work) Monday.". Friday's work may be transmitted in a few hours during this morning (Saturday) uplink session.

We may see Opportunity driving today. My 2c.

I didn't expect a drive yesterday - I assumed the planned one was for today (Sat) or tomorrow (Sun) before IDD on Monday.

Slightly tweaked 3D view of Marquette Island...

I have a lot of catching up to do after a whole month without broadband after moving home.

I was waiting for the rest of the filters of the Nereus Crater pan when I moved so that is easy to do:



BTW: Is it just me or is the PDT down?
