I was wondering that when I stitched the images together, and the first thing that came to mind was Khan's pet ear wig . . .
It is out of sight from the SOL 1 footpad image and nearly beneath the lander, but by the surrounding soil, it looks like it fell from the lander. The resoltion of the RAC is only 256 X 512 so we need to creep lower for a better look. |

If I had to guess what it was - I'd say something to do with...
-Biobarrier deployment -SSI deployment -Helium vent valve -RA deployment -Met deployment If I had to pick one - Helium vent valve. |

Could be ancient duricrust, buried under a more recent dust/soil layer.
Could be pavement-flattened rocks of the type we see in Meridiani, again underlying a more recent dust/soil layer. No. What am I thinking? It's ice. It just looks *obviously* like ice. Maybe not a perfect layer of water ice, but at the very least a good, solid permafrost layer. Looks like we'll need to burr some of that out, doesn't it? Looks really, really hard to me. BTW -- is there a danger of significant sublimation of exposed water ice at these pressures and temperatures? I'd hate to see the cleared permafrost layer under the lander sublimate out into a nice little Phoenix-gobbling sinkhole... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Probably not, since the blanket of dust and sand that has been keeping it all in place for eons would soon be replaced. If the patches under the lander started to slump they would gather nearby sand and dust. It would be covered before any significant slumping reached as far as the foot pads - I suspect. But it's a darn interesting thought to ponder. -------------------- If Occam had heard my theory, things would be very different now.

The arm can't get to THAT Ice, the 'upper arm' is probably longer than the height from where the arm meets the deck to ground. But - you can see that where the dust blew away - it's everywhere. 5cm of soil, then ice. As they predicted (maybe )

If it's ice: could the heat that the lander collects from sun radiation during daytime melt the ice under it's footpads ? ....slowly sinking in ? For rocks it doesn't seem to happen, the exposed surface of the whole lander (and the energy it collects) concentrates on quite small footpads though |
