To my eye the second spot looks like it was a bit more resistant than the first one was. The first one looks almost like an impression of the drill bit pressed into clay!

Hope it's as powdery as the dust streak suggests...

I can't wait to check out those new MAHLI images.
So here's both sols 172 and 173 (MastCam 100). We just need a mosaic facing NE - SE to make these two connect, which would indeed be incredible... Gigapan: http://gigapan.com/gigapans/122731 "Preview": -------------------- |

Nice MAHLI shots! And thanks for that before and after animated GIF! Here is a collage (images have been sharpened a tad):

Maybe a little clay-ey? Yes, by appearance, possibly a fine clay. I was sort of hoping that the drill tailings would be coarser, so that these tailings could more effectively help clean out the CHIMRA (sample handling system). Sol 173 MastCam images show extensive contamination of large areas of CHIMRA's chambers. This contamination is residue from the multiple scooped samples at Rocknest. The contamination (Regolith) has excellent cohesive properties. Let's hope the drill tailings can remove enough of the Regolith to ensure accurate science from CHEMIN and SAM, and that the tailings are not as cohesive to cause issues later in the mission. |

Its amazing how martian dust can colour everything red. Who would have thought that this part of Mars was so grey!

Note the hexagonal ChemCam laser marks in the upper left edge of the enlarged first image of each sequence ... Are you referring to those two sets of indentations in opposite corners and equidistant from the drill point? I think those are the marks left by the drill's pre-load support posts. In the earlier tests only up to three "points" were seen for each post but presumably the drill's vibration (and perhaps higher pre-load forces than before?) has left nice "constellations" of marks.
