Here is the MI images of the final parking spot of Spirit
(as Doug said, others may do a better job of sharpening... mine has brightness discontinuities between images...oh well!)

....Wow!

That sure makes me glad we have two of them!
But I'm hoping some trick of fate will give Spirit a fighting chance, too.

It's been said before, and often - Don't bet against Spirit, it's a great way of losing money...

Spirit's adventure is far from over yet, of that I'm sure. smile.gif

They had S-band radio, the rovers use X-band. I think that's the reason. They did do tracking with Pathfinder, but the mission didn't last long enough.


Results from Pathfinder were published in Interior Structure and Seasonal Mass Redistribution of Mars from Radio Tracking of Mars Pathfinder

the "superiority" MPF's (and Spirit's) X-band over Viking's S-band is explained in note 8:

QUOTE
The Pathfinder radio system operates at X band (8 GHz) compared with the S-band (2 GHz) radio system used by the Viking landers. The Doppler data noise caused by solar plasma is inversely proportional to the square of the radio frequency. The Pathfinder Doppler data have about 13 times less noise than the Viking lander Doppler data. The Doppler data noise is about 0.05 mm/s for data at 60-s intervals. The solar plasma also affects the round-trip range measurements. Calibrations for the solar plasma for some of the Viking lander data were determined from dual-frequency observations of the Viking orbiters. The Viking ranging data have a residual noise of ~7 m for data with orbiter calibrations and ~12 m for data with no orbiter calibrations. The Pathfinder ranging data taken so far have residuals of ~3 m.

I assume they will have time to upload the table before spirit goes "night night" ?

Anyone know what the final aspect was? How much of a northerly tilt did they end up with?

Offhand I think we have a 9 degree tilt to the South, but I'm more than happy to be corrected on that.

To the south? I thought they were angled north now?

No, Spirit is tilted 9 degrees toward the south :

Here is the IDD work volume pan taken between sol's 2163-2176 with L257. Lots of color variations in the soil smile.gif

Yes the tilt is South, time, energy and luck ran out for getting Spirit into a Northerly tilt. A bit like what happened to Phoenix, in the end sunlight rules what you can do and cannnot do.

Spirit is such a drama queen sometimes. I'm reasonably confident of a revival and a cleaning come next spring, but it's going to be a nail biting 2010 for our old gal.

The fine lamination of the rock in the center of the pic is quite interesting. seems like a clay deposit (deep water???). I hope there'll be some future detailed analysis of that.
