“…Thus, this method requires highly homogenized samples to relate K and Ar accurately. For such conventional techniques, a rock sample must be crushed into powder, increasing the complexity of the onboard instruments (Anderson et al, 2012). In contrast, our method favors heterogeneous rocks to construct a reliable isochron.…”

“…Engineering constraints were significantly more specific than the science constraints because this would be the first sample processed through the Sample Acquisition, Sample Processing and Handling system (SA/SPaH) [ M. S. Anderson et al ., 2012], located on the turret at the end of Curiosity's Robotic Arm (RA). Constraints were designed to assure the safety of the Collection and Handling for in situ Martian Rock Analysis (CHIMRA) portion of SA/SPaH (i.e., the scoop, sieve, and portioning system), the acquisition of sample amenable to use in dilution cleaning of the sampling chain [ R. C. Anderson et al ., 2012], and the ability to process an adequate amount of sample of the appropriate grain size for analysis by CheMin and SAM within the same working volume. These first‐time activities included scooping, transferring samples to CHIMRA, moving the RA and turret through a series of motions that passed scooped material across any interior surfaces of CHIMRA that could contact sample in nominal operations to reduce the contribution of adhered terrestrial organics, and portioning samples for delivery to CheMin and SAM.…”

During Martian solar days 57–100, the Mars Science Laboratory Curiosity rover acquired and processed a solid (sediment) sample and analyzed its mineralogy and geochemistry with the Chemistry and Mineralogy and Sample Analysis at Mars instruments. An aeolian deposit—herein referred to as the Rocknest sand shadow—was inferred to represent a global average soil composition and selected for study to facilitate integration of analytical results with observations from earlier missions. During first‐time activities, the Mars Hand Lens Imager (MAHLI) was used to support both science and engineering activities related to sample assessment, collection, and delivery. Here we report on MAHLI activities that directly supported sample analysis and provide MAHLI observations regarding the grain‐scale characteristics of the Rocknest sand shadow. MAHLI imaging confirms that the Rocknest sand shadow is one of a family of bimodal aeolian accumulations on Mars—similar to the coarse‐grained ripples interrogated by the Mars Exploration Rovers Spirit and Opportunity—in which a surface veneer of coarse‐grained sediment stabilizes predominantly fine‐grained sediment of the deposit interior. The similarity in grain size distribution of these geographically disparate deposits support the widespread occurrence of bimodal aeolian transport on Mars. We suggest that preservation of bimodal aeolian deposits may be characteristic of regions of active deflation, where winnowing of the fine‐sediment fraction results in a relatively low sediment load and a preferential increase in the coarse‐grained fraction of the sediment load. The compositional similarity of Martian aeolian deposits supports the potential for global redistribution of fine‐grained components, combined with potential local contributions.

In this paper, a novel method is proposed to extract rocks from Martian surface images by using 8 data field. It models the interaction between two pixels of an image in the context of imagery 9 characteristics. First, foreground rocks are differed from background information by binarizing 10 image on roughly partitioned images. Second, foreground rocks are grouped into clusters by 11 locating the centers and edges of clusters in data field via hierarchical grids. Third, the target 12 rocks are discovered for the Mars Exploration Rover (MER) to keep healthy paths. The 13 experiment with images taken by MER shows the proposed method is practical and potential.Comment: This paper has been withdrawn by the author due to a crucial sign error in equation
