Back to Astro0's question, how much clearance is left?

Judging from Astro0's last MI mosiac above, -- I don't think I want to know the answer to that question.

The forward wheel looks like it might now be below the surrounding ground level

Animation.
The sinking seems to stop toward the end.

Maybe she bottomed out

Something to remember when viewing the underside images: part of the reason you are seeing less bright surfaces beyond Spirit's silhouette is because Spirit's shadow now extends farther south due to the changing seasons.

The LF wheel has been turned inward as part of todays activities. Change of strategy?

 ...yeah.Might be the rationale behind any change in wheel angles. EDIT: This might be an attempt at some form of 'sidewinder mode'--sort of walking the wheel forward. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The left rear wheel has really been digging in during the last few drives
http://207.7.139.5/mars/spirit/rear_hazcam...96P1314R0M1.JPG http://207.7.139.5/mars/spirit/rear_hazcam...AUP1314R0M1.JPG http://207.7.139.5/mars/spirit/rear_hazcam...BAP1314R0M1.JPG http://207.7.139.5/mars/spirit/rear_hazcam...BBP1354R0M1.JPG I suspect this is also having an adverse effect on Spirit's tilt. |

If Spirit remains here into the winter, is this downwards movement tilting the panels away from the sun?

It may be that Spirit will never be able to climb uphill again.
 However what I wondered is whether Spirit might be able to drive further into the small crater in which it may be stuck?If I understand what Scott Maxwell and others have said correctly then Troy is the most scientifically interesting location that Spirit has yet encountered. Would there be any value in sampling a different area of this small crater? I also wondered whether Spirit might survive the winter better if its warm electronics box was partially buried in quicksand? Finally I wondered whether with a warm electronics box that was touching the ground, Spirit might better detect marsquakes? |

The next rover design had better incorporate a telescoping powered leg with 360 mobility.

What other elements of design are you prepared to drop to make room for that?
It's very easy to say "they should have given the rovers this..." without any consideration for how. |
