The most recent self-representation from NASA's Curiosity Mars rover demonstrates the auto size portable research facility alongside a dim ridge where it has been scooping and sieving tests of sand. The new selfie consolidates 57 pictures taken by the Mars Hand Lens Imager (MAHLI) camera toward the end of Curiosity's arm on Jan. 19. The rover has been exploring a gathering of dynamic sand rises for two months, concentrate how the wind moves and sorts sand particles on Mars. The site is a piece of Bagnold Dune Field, which lines the northwestern flank of Mars' Mount Sharp. At the point when the segment pictures were taken, the rover had scraped the edge of "Namib Dune" and gathered the first of three scoops of sand from that rise. It utilized its scoop later to gather a second example on Jan. 19, and a third on Jan. 22. Amid preparing of the third specimen, an actuator in the example handling gadget did not execute obviously when instructed. This week, the Curiosity group is distinguishing conceivable purposes behind the actuator's execution. The preparing gadget on the arm is named CHIMRA, for Collection and Handling for In-situ Martian Rock Analysis. The part that was instructed to open, however did not, is known as the CHIMRA burrow. It is opened by utilizing the smack actuator, a mechanized segment that likewise can convey a firm tap to clean example material from an adjacent strainer. Part of the third scooped test is inside the CHIMRA burrow in the wake of going through a sifter. In the event that the passage had opened by means of the smack actuator as arranged, the following step would have been to take a picture of the sand inside it. "The rover reacted legitimately to this surprising occasion," said Steve Lee, representative undertaking supervisor for Curiosity at NASA's Jet Propulsion Laboratory, Pasadena, California. "It quit moving the actuator and ended further utilization of the arm and inspecting framework." While symptomatic work advances, the group likewise is keeping on utilizing the remote-detecting instruments on Curiosity's pole and ecological checking instruments. One part of the hill examination is to see the same area over and again to check for development of sand grains brought about by wind on Mars. In the event that development happens, the group can utilize the rover's wind estimations to make sense of the quality and bearing of the winds that brought about the development. On the second scoop from Namib Dune, Curiosity effectively utilized two unique sifters as a part of CHIMRA to set up a bit for investigation. This two-strainer system had not been utilized beforehand as a part of the rover's three-and-a-half years on Mars. The subsequent part was comprised of sand grains sufficiently huge to be kept down by a sifter with pores of 150 microns (0.006 inch) and sufficiently little to go through a strainer with pores of 1 millimeter (1,000 microns or 0.04 inch). This middle of the road grain-size part was conveyed to the rover's inner science investigation lab. The third scoop was to have been handled the same way, however the science group chose for the current week that the segment conveyed from the second scoop will suffice. At the point when the rover drives on after analytic work on CHIMRA, it will have completed its examinations at Namib Dune. The mission's examination of dynamic sand rises - the main ever concentrated on very close other than on Earth - is giving data about dynamic ridge forms in conditions with significantly less environment and less gravity than on Earth. Analysts are assessing conceivable locales for the following utilization of Curosity's drill to gather rock-powder tests of the bedrock in the territory. Interest achieved the base of Mount Sharp in 2014 after productively researching outcrops closer to its arrival site and afterward trekking to the layered mountain. On the lower bit of the mountain, the mission is concentrate how Mars' antiquated surroundings changed from wet conditions positive for microbial life to harsher, drier conditions. /Nasa.gov orginal post/
