I still find these fascinating. ...especially when viewed in stereo, looks like a dump of rusting office supplies here, one 'pencil' is poking up sharply near the middle. The inordinately white veins perhaps sourced from or coevolved with larger light toned deposits along faults?, don't miss the tiny warbly vine complete with shadow at the top of the little crossbedded crosshatched stack remnant in the lower left quadrant of the second crosseye.. (also added an anaglyph of the first img and the warbly vine area) |

Curiosity Mission Update from Lauren Edgar "Sols 1089-1090: Stimson is Stunning" LINK
QUOTE ...Today we’re planning 2-sols for the weekend (Sunday is a “soliday” to allow Earth and Mars schedules to sync back up). One of the main activities on Sol 1089 is dropping off part of the Buckskin drill sample to SAM. Then we’ll dump the Buckskin post-sieve sample, and analyze it with APXS. The plan also includes Mastcam and MAHLI imaging to document the dump pile. Sol 1090 consists of several ChemCam observations of the targets “Fox Hills,” “OBriens Creek,” and “Bearpaw” to investigate the bedrock and local alteration features. We’ll also acquire a large Mastcam mosaic to document the stratigraphy, and a Navcam deck pan for dust monitoring...

Yikes, thanks for posting those, atomoid - definitely some of the craziest erosion remnants we've seen. Edit: ML view of that "pencil": No matching MR yet. |

JPL have not updated their Curiosity traverse map for several drives, so I have taken the liberty of copying the the path and place names from Phil's latest update onto a cropped version of the last JPL issue (1074). I have also annotated the possible future paths that was shown in JPL's Rover recent video update. Note that they have shown two paths around 'Bridger Basin'...
Whichever path they eventually use, I think we will see some spectacular images. Full size (3650 x 2507) LINK |

Interesting. Are these little berries or just clumps? If berries, they would have to be tough enough to be drilled out of a softer matrix without getting broken up. I don't see any half berries.

Interesting. Are these little berries or just clumps? I believe we are seeing 'Clumps'... This is the sieved sample, and has passed through the 150 micron sieve. We have seen other examples of highly cohesive sieved samples in the recent past. I don't know what height this sample was ejected from CHIMRA, but I suspect it was rather close to the ground, as this would reduce the odds of the sample being dispursed by a light wind, which could make measurement with the APXS very difficult. |

I am unceasingly impressed by Curiosity's strength, precision, and stability.
(thumbnails recently downloaded from Sol 1089) One of the greatest demonstrations of this that I can think of is when it's checking a full rotation of its wheels, like these images from Sol 1046. (Click for GIF) and (Click for GIF) If you didn't know any better, you'd probably assume it left the camera there while it rolled forward, pausing 5 times to capture these images, then moved to capture a different wheel and did 5 more frames from that angle, and so on. In reality, it only performed a single revolution. After each increment, it moved the camera into position to snap a single frame, then moved the camera to several other locations to capture a frame from those angles as well, taking between 15-25 seconds for the camera to move to the next position, capture a frame, and move on. For each frame, it was able to return to the exact same position it had been in earlier, enabling an animation to create the illusion that the camera never moved. This gets even more impressive when you realize that it didn't return to the same position relative to the rover body or chassis, but rather relative to the hub of the wheel it was imaging (you can see the rockers moving while the target wheel stays fixed in the frame). |
