Now we have a new drill target:

This is the according raw Sol 192 Mastcam Right image showing 'Cumberland', here some more context, and here a Sol 269 Navcam Right B image with the right front wheel on the same image.

Regarding cross-contamination mentioned in the article announcing Cumberland as the next target - is it known to what degree that might occur?

If you recall some welds broke on a filter screen inside the CHIMRA (Sample Handling Unit) on the CHIMRA being used here on earth. This has led to the engineering team significantly reducing the use of the voice coil which 'thwacks' the unit inside Curiosity. That thwacking is used for cleaning as well as sifting.
Images taken prior to drilling at John Klien showed significant quantities of residual Rocknest material inside all of the CHIMRA chambers. I do not recall seeing a set of 'post cleaning' images, but the drilled sample inside the scoop appeared to be the same color as the tailings adjacent to the hole. This would suggest little cross contamination. They will probably sequence another set of CHIMRA chamber images before drilling at Cumberland. Hopefully the John Klien drill cuttings are less cohesive than the wind blown Regolith at John Klien, thus allowing more thorough cleaning with reduced levels of thwacking that could reduce the cross contamination even further. Maybe they will sequence a set of CHIMRA chamber images 'post cleaning' the John Klien sample as to assist in quantifying the degree of contamination.

OK, back to work on Monday!

If the RHaz pics tell the whole story, they have just backed up so far.

Also now oriented 228° (was 166°). Might that not be just about what was needed for the arm to reach Cumberland, only 2.75 meters west of JK?

Based on the NAIF data, looks like it turned to 175°, backed up about 0.9 m, turned to about 230°, went forward about 1.2 m.

After the drive (12:22:47 p.m. LMST) Cumberland is located straight in front of the rover, visible in this HazCam Left B image, taken sol 272 12:42:36 P.M. LMST according to your website http://curiosityrover.com/. Compare it with this Sol 269 HazCam Left B image. I'm close to agree with you, but might be they'll drive forward a little bit to reach Cumberland better, we'll see.

Here the first 11 of a sequence of Sol 271 ChemCam images I wanted to mention:

Link to the animated GIF.

The LIBS shots have taken place within a very narrow region. That's an observation type I didn't notice before, might be a new one, probably to get a more representative analysis result over a wider range of mineral grains.

That will be the case according to the USGS mission blog. Hence the imaging post-drive.

Not sure, they plan to dig another hole in the ground laugh.gif
BTW, I'd said we'll need to add an "s" to drill or open up a new thread.
