Curiosity has just concluded a very intense week of science observations and engineering activities, as it wraps up its monthslong investigation of the Martian boxwork terrain. Three days of planning this week by the MSL science and engineering team has led to three rover drives, three sets of targets for detailed study by instruments on Curiosity’s arm, and a vast array of in-situ data characterizing the southern reaches of the boxwork terrain on the shoulder of Mount Sharp on Mars.
As the week began on Mars sol 4838, Curiosity used cameras on Mastcam and ChemCam to image ridge and butte targets “Salar de Maricunga,” “El Misti,” “Saipina” ridges and the “Paniri” butte. Mastcam also looked at bedrock fractures on target “Sajta.” The laser spectrometer on ChemCam examined the composition of the target “Tacitas.” After brushing away a great deal of dust off the bedrock target “Toro Wharku” with the DRT, then MAHLI and APXS studied it in detail. MAHLI also performed detailed imaging of the nearby ledge “Rincodillas.” In the afternoon, Mastcam Tau and Navcam line-of sight observations measured the amount of dust in the Ma …
