exhumed meteorite fragment or specular deception? m34/m100 cross anaglyph and detail in parellel view, but clearest view in the sol1847 original
Actually made me think of that 'italy' prong way back at yellowknife(discussion), which looking back was probably a meteorite fragment still embedded.

A small move on sol 1843... but just a turn in place, I think. If it was intended, it may be to reach an interesting target with the arm. Otherwise it might be an aborted drive. No map update for this.

It was an aborted drive. Not sure about the details since I was out of the office today but saw the fault on my email update.

Here's a cheat for those following along at home. Every day there is a drive or robotic arm stuff planned, ECAM delivers a sequence called FHAZ00190

It's an off-nominal image - if something happens that causes a drive to abort early or an arm sequence to stop unexpectedly....then FHAZ00190 gets taken.

Such as https://mars.jpl.nasa.gov/msl/multimedia/ra...90M_&s=1839

If it's a drive - quite often - the rest of the post drive imaging will still occurs such as a normal end of drive FHAZ, RHAZ and series of NavCam sequences - which is why there's an FHAZ00337 taken shortly afterwards..

Thanks, Jan. Here is your panorama in circular form. Moving along the ridge a bit. A map update will follow shortly.

Could be the mind wanting to see patterns, pareidolia, but there seem to be several linear or rippled features in those pebbles...

Wonder if CO2 frosts and dunes can churn martian soil the same way freeze thaw does on earth...

...linear or rippled features in those pebbles..

I've noticed those elsewhere too and wondered if i was just seeing things, but I think they are for real, and they do seem mostly parallel..
<disclaimer>my novice armchair pseudo-geologist perspective that hopefully more knowledgeable folks can clarify or shoot down for us</disclaimer> is that any frost heave structures this small would be overrun quickly by aeolian effects. I suspect that the tendency of the pebble bits to settle into somewhat linear features is purely deflationary, one guess is that as the surface deflates, remnant bits should tend to migrate downslope until they come to rest against other bits, and the tendency of the linear features to be parallel to each other probably reflects the prevailing wind direction (sand ripple building affecting the transport of the bits) or an effect of the original layer structure of the bedrock they eroded from.

on a different note, aside from the 'atmospheric dust' confounding any sense of landscape direction, this is pretty cool https://accessmars.withgoogle.com/
