Here's the navcam mosaic taken at the current site; that's sol 2061.

In Tesheiner's latest mosaic, the visible side of Marquette does not now seem so different from the other side . . .

Considering how narrow the base appears to be; what are the odds of it tipping over and the bottom edge hitting the IDD if they try to RAT this thing?

I proposed toppling it in post 596 but there were no takers for the idea. I still think they should try provided there is a safe way to do it. If it falls you see freshly exposed surface; if it doesn't then at least you know it isn't about to fall accidentally.

So, which side will you choose? That's far too dangerous I'd say. If it starts to move and come back on the IDD or whatever part of OPPY would be chosen to push...we're dead.

Does anyone have a size/mass estimate? That might shed some light on the risk of accidentally tipping this thing over?

QUOTE (climber @ Nov 11 2009, 05:34 PM)  whatever part of OPPY would be chosen to push.. I was thinking of a wheel. Which side to push? The one that isn't overhanging.

Hmmm... big cloud of dust going who knows where, pebbles being dislodged and flying around. Sounds like a bad idea to me...

Way too dangerous -- if it could be done.
I would think that Martian winds pressing on the entire face of the rock could rival the pushing force of Opportunity pressing on a square centimeter or so. And it hasn't tumbled yet. Not that I've done the math.  edit: QUOTE (ngunn @ Nov 11 2009, 02:09 PM) I was thinking of [pushing with] a wheel. Pushing below the center of mass?

I can't think of many things more terrifying than Oppy trying to topple that thing!
 I seriously doubt it would be possible anyway, it doesn't look that unstable to me. Anyway, going back a coupe of weeks, I'm still catching up. Here is Trinidad Crater:  James -------------------- |

Beautiful feast of Pans of Sol 2059 (Mon Nov 9). Sorta took my breath away. Couldn't resist just doing a quick job on them. Hand stitched, few adjustments and colourized. I'm sure someone else will do them justice!!
Will post the full res pic on Flikr - 1.8Mg and edit link in here a bit later when I have time.

Most likely outcome of Opportunity pushing on rock: No movement of rock and possible damage to Opportunity.

How did we miss this? Better watch out for the Meridiani bears...

Oh, no! The dreaded Martian Desert Seal!!!
