The view is getting stunninger and stunninger (for one as easily stunned as me). Here are Jan's two latest panoramas in circular form.

Probably a superb image Charborob, but unfortunately Flic.kr is yet again declining to play.

A pair of rather interesting ChemCam Targets from sol 1831, shown in context on a resized version of the L-MastCam workspace from 1830
The mission update refers to them as "Normandien," and "Black Reef." Besides the interesting shapes, any thoughts on the small surface pits? |

Strange little beasts. Normandien appears to be shot through with crack-filling intrusions of white material, so possibly metamorphized. The pits may have been inclusions of some other mineral that either evaporated out during the metamorphism or eroded away after the rock reached the surface.
(Sheer guesses; let's see what the real geologists say. ) -------------------- 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.

I've seen voids like that in red mudstone, usually casts of carbonate or salt crystals that later dissolved. Hmm, micro-kettles when the loss inclusions salt, water ice or dry ice create voids? What sort of stability do water ice or dry ice have at the guesstimated deposition temperatures and pressures? |
