Some great new RMI images looking over the dunes to the terrain beyond, on sol 1181...

Here is a mosaic using the 5 overlapping RMI's (MS ICE)

....Can you do for SOL 1176? There is an awesome disturbed area...

QUOTE
Today we are planning the last sol of the mobility test, turning and backing out of the sand while taking multiple Hazcam images, then pausing to take Navcam and Mastcam images of the wheel tracks. But first, Mastcam will take multispectral images of a rock named “Narabeb” and a soil target dubbed “Kubib.” The right Mastcam will also acquire another 2x2 mosaic of Secomib, to look for changes in the trench wall, and image the spots where the APXS was placed on the sand. The biggest challenge for me as SOWG Chair today was to prioritize the post-drive data, as the volume of data expected to be received in time for planning tomorrow is smaller than usual. We’re hoping that the rover will drive close enough to “High Dune” to allow contact science on the dark dune sand, so we’ll need good images of the arm workspace. But we’re also planning to drive again this weekend, so we’ll also need images in the direction of the drive. It looks like we will get just enough data to enable a full weekend plan, assuming that all the orbiter and ground assets work as we’ve come to expect.
Later in the afternoon, the ChemCam RMI and right Mastcam will acquire a small mosaic of an outcrop up on Mount Sharp, and both Mastcams will image the ground in front of the rover. Finally, the left Mastcam will acquire a mosaic of the ground and sand to the right of the rover, and MARDI will take another twilight image.

Looks like on Sols 1174, 1176, and 1178, Curiosity reimaged a small outcrop of bedrock for dust movement.


Bagnold Dune Monitoring - Sol 1176 by Justin Cowart, on Flickr

Interestingly, it looks like there was some wind movement between Sols 1174 and 1176, as most frames show at least a couple white clasts moving between frames. I don't see similar movements between Sol 1176 and 1178.

Here's a preview gif with the frames aligned. It's pretty heavily compressed to get it down under the 1mb limit. It should still be sufficient to see some of the larger clasts moving.

Here's the full size version with less compression. There are a few smaller clasts also moving around.

Due to artifacting in the public data, it's really hard to tell if smaller grains are moving, or if it's just the larger white clasts. It'll be interesting to find out over the coming weeks!

This reprojection of the sol 1183 hazcams lets me find the new location for the map.

Sol 1181 RMI-ChemCam target shown in context on a debayered R-MastCam and HiRISE from Google Earth using Fernando's KML for the path.

I used the measuring tool within GE to estimate the point-to point distance from the rover to the RMI target, which is fractionally under one mile (1575 meters, 0.98 miles). If I have correctly identified the RMI target, it's a ~100 meter (330 feet) wide Butte located ~122 meters (~400 feet) beyond the southern edge of the Bagnold Dunes.
Some of the detail can only be enjoyed by viewing the full size montage at 6440 x 2245 pixels LINK

Sol 1182: Overlapping MAHLI's acquired at Dune #2. Assembled with MS ICE. Presented in raw, enhanced and grey-scale.
Scale bar added in lower right, thanks to Gerald. Focus stacked images have not yet been downlinked, but we can see a lot of detail in these images of the Bagnold Dune sands smile.gif

Sol 1185: Midnight Planets reports a drive ~31 meters due east, LINK still missing one frame of the end-of drive images to make the 360
Appears after a brief stop to check out some older tracks the rover could be heading for Dune#1?
Here is a look ahead assembled from just 4 L-NavCams using MS ICE while we wait for the last frame

Great! This is a circular version of it.

Context image for the MAHLI mosaic I posted here yesterday. I originally thought these could have been few sand covered hitch-hiking pebbles that were ejected from the inside of the wheel onto the side wall of the trench. Now I am not sure, these could be clumps of compacted sand or a compressed layer of sand. Thoughts?

Upper layer of sand might have a bit of grain interlocking going on. It looks like they just rolled in from the side when the wheel trench slumped.

I debayered the images in gmic, and cleaned up color artifacts with the 'color replacement' tool in Photoshop. A bit of sharpening and color adjustments, and it was good to go!

Here is the Mission Update by Lauren Edgar: Sols 1187-1188: Analyzing bedrock and sand LINK
QUOTE
After successfully completing a mobility test last week (as seen by our wheel tracks through this sand patch), Curiosity drove ~35 m toward a dune that is now named “Namib.” We’ve accomplished a lot of reconnaissance imaging of the dunes, and we’re looking ahead to monitoring the dune slipface and sampling the chemistry and mineralogy of an active dune. We’ve also acquired some beautiful close-up images of the sand grains, as seen in the above MAHLI image that just came down.

Today’s 2-sol plan includes a targeted science block followed by a drive and post-drive imaging, and an untargeted science block on the second sol. Sol 1187 includes several ChemCam and Mastcam observations of the local bedrock at targets named “Rehoboth,” “Hamilton_Range,” and “Twyfelfontein.” We’re also testing out some software for autonomous target selection. Then we’ll drive towards the “Namib” dune and take post-drive imaging to prepare for future targeting. Overnight, Curiosity will perform a SAM Electrical Baseline Test to make sure that the power and data interfaces are all operating smoothly. On the second sol we’ll use ChemCam, Mastcam, and Navcam to monitor the composition and opacity of the atmosphere and search for dust devils.

My take on RMI-Chemcam mosaic colored with a MC100 picture. Pictures taken on sol 1181 at 15h08 and 15h23 local time.
