Spirit's brushed the rock it stopped near yestersol
 Looks a HELL of a lot like adirondak to me! - compare the MI image of the Adirondak brushing 11 months ago...  With the brushing of this rock...  YEah yeah - ok - they're TOTALLY different - but I'm not a geologist - makes an interesting comparison however. I assume this will be the weekend stop-over. Doug |

Comparing the rear hazcam views from 12-29 and 1-5, it does look like they've driven a little ways. You can still see a heck of a lot of slippage in all the churned up sand.

As yet more, post-grind MIs of a new rock come in, it occurred to me that what we really need is a RAT that operates in three modes. The brushing works well, and so does the grinding, but a third phase of polishing would really improve the imaging of the internal textures of these rocks.
The scratches and left-over detritus from the grinding operation really obscure the details. They don't interfere much with the spectrometer measurements on the post-grind surface, but they really detract from the imaging. If the metaphor of a robotic geologist still applies to the rovers, I suggest that we need a way to smooth out the post-grind irregularities. On earth, a geologist would simply lick the surface prior to viewing it with a hand lens, since further polishing is an energy intensive operation. Wetting the surface greatly improves the visual resolution. I can imagine a tool that sprays an aerosol of some appropriate, low vapor pressure, low freezing point oil onto the surface. -------------------- ...Tom

You guys are the bomb. You noticed that Wishstone was quite a unique rock before NASA acknowledged it.
I've been looking for images of Wishing Well rock since it's supposed to be high in phosphorus like Wishstone. Perhaps it's the rock referred to by CosmicRocker here: http://mer.rlproject.com/index.php?showtopic=522&st=16 Bob Clark |

Except, at 100 kg I'm probably a little heavier than an oil-sprayer. -------------------- Jonathan Ward
