Time for a new thread.
After moving southwards for ages, the "detour" by the western path has started with a 60+ meters drive on sol 1942. There are no images yet --they should be available on the next update-- so this image was calculated solely based on the rover's mobility info. I'll update the route map later. |

It's interesting to see how differently people are interpreting this fascinating rock.
It clearly displays regmaglypts, but I doubt the deepest hollows can be explained as erosionally enhanced regmaglypts. I'm not sure it is appropriate to call them vesicles, either. I'm siding with a previous commenter who suggested that some hollows may be due to inclusions which subsequently corroded or eroded away. I think the deeper pits on the right side of the rock and the surrounding "filigree" features may be mostly primary structures. It is interesting, however, that certain features seem to be aligned with the current wind regime in this region. I'm not sure how to interpret that. Has the morphology of this meteorite been shaped by recent winds on Mars, or is it due to the winds experienced by the intruder as it entered the atmosphere? If I had to interpret the morphology of this meteorite as being formed by its flight through the atmosphere, I'd suspect the leading edge was on the left. Finally, regarding the pedestal, good catch, alan. A remnant like this is likely to protect a pedestal beneath it, but this most recently protected pedestal is not likely to have been the first pedestal this lagging boulder has perched upon. -------------------- ...Tom
