This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA’s Curiosity Mars Rover shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.
The scene combines multiple frames taken with Mastcam’s right-eye camera on Aug. 7, 2014, during the 712th Martian day, or sol, of Curiosity’s work on Mars. It shows an outcrop at the edge of “Hidden Valley,” seen from the valley floor. This view spans about 5 feet (1.5 meters) across in the foreground. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Figure A is a version with a superimposed scale bar of 50 centimeters (about 20 inches).
This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits. These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of river sediment settled out of the water column and onto the lake floor.
An image from Curiosity’s Mastcam (left cam) showing surface texture on Mars. A thin coating of dust is starting to accumulate on Curiosity, but so far it looks pretty good. I am not sure of the image scale.
The image was taken on 23 November 2014 in the Mount Sharp area where it has been driving around taking a look for good sites to examine.
You will notice some cosmic ray hits are labeled. Very common artifact as anyone who dabbles even a little in astrophotography will attest. This image has been processed to remove detector artifacts and a slight twilight glow. The processing was very well done, sometimes the processing is half the fun.
You can see more images, including a blink between two frames from Opportunity. Do have a look.
Here’s a look at Widowiak Ridge on Mars from the rover Opportunity on sol 3,786! The color approximates natural color on Mars.
The ridge is on the western rim of Endeavour crater, this look is about 70 compass degrees from north-northwest on the left to east-northeast on the right. Widowiak Ridge rises about 12 meters / 40 feet and runs about 150 meters / 500 feet. The view of the area from above.
The name Widowiak is an informal name given to the feature given as a tribute to Opportunity science team member Thomas J. Wdowiak (1939-2013). Informal? Perhaps an exception to the naming convention is in order.
Last week I mentioned the Mars Science Laboratory – Curiosity was at an interesting rock and mission managers were evaluating it to see if it would be a good choice for a sample collection (see the post).
Before there is a sample collection Curiosity uses the mini-drill procedure to aide in evaluating the location. Part of using the percussive drill for making a starter hole, probably akin to a hammer drill many of us use now and then. During the starter hole step Bonanza King moved a little bit and the protective software on Curiosity sensed it and stopped the procedure.
Mission managers decided to move on towards the long term goal of reaching Mount Sharp. Maybe they will find something interesting along the way.
