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
