You wait around god knows how long and the first thing you meet shoots you. Three times!!!



That just doest look like a meteorite to me...it looks manufactured. What are the chances it's a piece of curiosities upper stage from years back

Looks natural to me. The cruise stage impacted 80 km to the west:

But the ChemCam spectra will reveal the composition and let us be sure.

Yes, the closest artificial parts to where we are now are the skycrane remnants (which flew west), heat shield/back shell, and the tungsten counterweights, which impacted far north of here (and would be probably a different shape entirely). This an unrelated arrival from space wink.gif

There is no indication of surface trauma around the object. This implies that it impacted at a higher surface level in the distant past.

Hmm, I hope somebody is keeping track of hematite spheres and meteorites,
so that there's an eventual estimate for how many feet of rock eroded to leave them as lag deposits....

That estimate would come from the geometry of layering and the current topography.

Here is a circular view of Jan's latest panorama. We can now head due east over the least sandy patch in front of us, then south, and presumably loop back a bit to the west to reach Ireson Hill.

We have seen a number of these somewhat unusual meteorites recently. For example, Egg rock, confirmed to be a nickel iron meteorite.
http://mars.nasa.gov/news/curiosity-mars-r...-iron-meteorite

There is the possibility that these all originated in the same incident as part of a strewn field, which would imply meteoroid fragmentation in a more dense atmosphere. It will be interesting to find out if the zaps in this example give the same result as Egg Rock.

Did they get a sampling of the odd "horseshoe inclusion" to the right?

To my eyes, it looks like a piece of the meteorite still embedded in stone, as if the meteorite formed
a small yardang and then toppled over. That would require that the meteorite was buried and then exhumed.

Yes, that's a beaut alright!

We just had a drive. Here is a Hazcam reprojection of the new location:

It looks like a drive of about 50 m, southeast and then south. Map update tonight.

...now wishing i had one of those super-widescreen monitors to desktop charborob's excellent stitch of that most impressive sol1580 butte.
found the meteorite candidate also imaged in several navcams from sol1576. here's an anaglyph and parallel excerpt::

From the 'Red Planet Report' dated 17 January 2017: According to MSL Project Scientist Ashwin Vasavada of JPL, “This shiny object, called ‘Ames Knob,’ was noticed in recent images from Curiosity. It resembles the iron-nickel meteorite, ‘Egg Rock,’ that Curiosity examined in November, so this target was inspected with the laser-firing ChemCam spectrometer. It yielded similar results (i.e., iron and nickel), so possibly a meteorite.”
