Do I see blueberries in the foreground? I don't think they're blueberries (iron oxide concretions) per se, but more nodular concretions of whatever cement is holding the mudstone together. I think on closer inspection that the Murray formation here will look more like this rock observed back on Sol 1256. |

Here are some postcards from Sol 1276...

I'm projecting these onto my study wall using a 3D projector with active 3D shutter glasses and its quite the view. -------------------- |

1275 L-MastCam 5-Frame mosaic, assembled in MS ICE, without any additional processing. I foresee some interesting driving conditions atop this plateau

2 USGS Mission Updates from Ryan Anderson:
Sol 1277: Nodules! Our drive yesterday was a success, putting us right on the contact between the “Murray” and “Stimson” units, and in reach of some very interesting nodules. The plan today is mostly focused on studying those nodules. ChemCam has an observation of a nodule and neighboring bedrock at the target “Vogelfederberg” followed by a “depth profile” on one of the nodules named “Verbrandeberg”. For the depth profile, we will only analyze two locations on the target, but we will shoot each location with the laser 150 times instead of the normal 30 shots. These extra shots allow us to measure changes in the chemistry in the outer surface of the target. After the depth profile, ChemCam will analyze two other nodule and bedrock locations named “Maieberg” and “Mikberg”. Mastcam will take documentation images of all of these targets. Later in the day, we will use MAHLI to take some images of a nodule named “Sperrgebiet”’, plus a broader mosaic of the nodular texture. APXS will then measure the composition of Sperrgebiet and the neighboring bedrock. Tomorrow the plan is to back out of our current location and then drive up onto Naukluft plateau! Sol 1278: Nodules: Take 2 Our APXS observation of the nodules in yesterday’s plan didn’t go exactly as planned: it was slightly misaligned with the nodule we were trying to analyze, so the measurement was mostly of the neighboring bedrock. That meant planning today started with a discussion of whether the chemistry from ChemCam was sufficient, or if we should spend another day and nail the APXS measurement as well. In the end we decided to try again and make sure we get all the data we want about the nodules before moving on. The Sol 1278 plan starts with ChemCam analyses and Mastcam images of the targets “Tsarabis”, “Lofdal”, “Kunene”, and “Nababis”. Mastcam also has two mosaics to capture the contact between the “Murray” and “Stimson” formations and the transition from knobby nodule-rich bedrock to less nodule-rich bedrock. After that, MAHLI will collect images of the nodule targets “Sperrgebiet”, “Maieberg”, and “Konigstein” and APXS will try again to do an overnight measurement of the composition of Sperrgebiet. Since this is the second try, the rover planners have yesterday’s data to work with and should be able to place the APXS more accurately. If all goes well, we should be able to wrap up at this location and drive away in the weekend plan! 1277 |

I talked to Ashwin today but probably won't write it up until next week, so a tidbit for now: he told me that they spotted these nodules a couple of days ago and thought they were cool enough to detour for, so they are at a "dead end" in terms of the drive, will focus on them for the weekend, and then plan to backtrack a bit next week before continuing uphill and onto the plateau. It's endlessly fascinating how varied the appearance of the Murray-Stimson contact is from place to place.

Curiosity Mission Update from Ryan Anderson (March 11th) Sols 1279-1281: Climbing up onto Naukluft Plateau
QUOTE It’s time to wrap up our investigation of the interesting nodules at the contact between the Murray and Stimson formations and resume driving! The weekend starts off focused mostly on contact science. On Sol 1279, APXS will analyze two neighboring locations on a group of nodules collectively called “Khomas”, and then on Sol 1280 APXS will analyze a third location on Khomas. MAHLI will collect supporting images, and will also take some pictures of the targets “Etendeka” and “Maieberg”. In the morning on Sol 1280, the rover will make some atmospheric measurements using Navcam, Mastcam, and ChemCam, followed by a 20-spot ChemCam analysis of the target “Marienfluss”, right across the Murray-Stimson contact. Mastcam will take a support image of Marienfluss, plus a small mosaic of a target called “Kerpfenkliff”. Then on Sol 1281, we will get moving again with a ~70 meter drive that should take us up onto the Naukluft plateau. During the drive, MARDI will collect some images of the terrain underneath the rover. After the drive we have post-drive imaging, and I added a request for some Navcam images of Mt. Sharp to help target potential long distance ChemCam RMI images next week. |
