Scientists
using NASA's Curiosity Mars rover are eyeing a rock layer surrounding the base
of a small butte, called "Mount Remarkable," as a target for
investigating with tools on the rover's robotic arm.
The rover works
near this butte in an image taken on April 11 by the High Resolution Imaging
Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter
.
A rover's-eye
view of Mount Remarkable and surroundings as seen from Curiosity's position in
that HiRISE image is available in a mosaic of images from Curiosity's
Navigation Camera (Navcam).
The butte
stands about 16 feet (5 meters) high. Curiosity's science team refers to the
rock layer surrounding the base of Mount Remarkable as the "middle
unit" because its location is intermediate between rocks that form buttes
in the area and lower-lying rocks that show a pattern of striations.
Depending on
what the mission scientists learn from a close-up look at the rock and
identification of chemical elements in it, a site on this middle unit may
become the third rock that Curiosity samples with its drill. The rover carries
laboratory instruments to analyze rock powder collected by the drill. The
mission's first two drilled samples, in an area called Yellowknife Bay near
Curiosity's landing site, yielded evidence last year for an ancient lakebed
environment with available energy and ingredients favorable for microbial life.
The rover's
current location, where multiple types of rocks are exposed close together, is
called "the Kimberley." Here and, later, at outcrops on the slope of
Mount Sharp inside Gale Crater, researchers plan to use Curiosity's science
instruments to learn more about habitable past conditions and environmental
changes
