Curiosity has put more than 400 meters on the odometer and tosol (sol 56) she bumped up to a sand drift that we now know (via Twitter) is named Rocknest and will be the site of the first sample grab. In last week's press briefing, John Grotzinger warned that we will be here for "what seems like a very long time," 2-3 weeks. They will have to run several samples through the SA-SPaH (Sample Acquisition, Processing and Handling subsystem, pronounced "Saw-spa") and in particular CHIMRA (Collection and Handling for In situ Martian Rock Analysis, pronounced "chimera") in order to "clean" it of any remaining Earthly contamination with good Mars dirt before they deliver the first sample to SAM or Chemin. So this seems like a good place to start a new thread.
As usual, discuss stuff that happened through sol 56 in the previous thread. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

I've been playing with ImageJ to make some false color images from the narrowband filters. Here's a comparison of various filter combos for a rock imaged on Sol 72 with Mastcam100.
I tried to include some combos that were familiar from MER such as equivalents for L257 and R721. (though since I was using the MR images only I had to go with a nearby filter, substituting MSL R3 for MER's L/R2). The 621 is to explore the further IR. And the funky colored one uses the formula describes in this thread on mineral identification (though I'm not sure of some details there, so no idea if it's actually useful for that - I had to stretch the ratio channels to make them show up). I also did slightly contrast stretch each of the filter combo images (but the same stretch for each channel). If I can figure out how to link to larger files, I can post larger versions if any of these are useful. |
