On September 24th,
the NASA's Mars rover Curiosity collected its first taste of Mount Sharp. Mount
Sharp, with a height of 3.4 miles, had been the rover Curiosity’s main
destination since it was launched in November 2011. On Sept. 22th,
the rover made a test drilling to a target rock on an outcrop at the mountain’s
base called “Pahrump Hills”. The objective was to measure its suitability for
sample collection. The test resulted satisfactory, encouraging the mission team
to proceed with a full-on drilling operation on Wednesday, Sept. 24th.
The rover drilled about 2.6 inches (6.7 centimeters) deep into the basal–layer
of the mountain and collected a powered-rock sample. Curiosity's robotic arm was
used for close-up inspection of distinctive features on the nearby surface of the
rock. The team now hopes to gain information about composition of fluids at
that location from long ago and its progressive composition since the mountain
was formed. "This first look at rocks we believe to underlie Mount Sharp
is exciting because it will begin to form a picture of the environment at the
time the mountain formed, and what led to its growth." said Curiosity Deputy Project Scientist
Ashwin Vasavada of JPL.
The next steps of the
mission is to run the sample through parts of the rover’s internal chemical
lab. The Chemistry and
Mineralogy instrument, a tool in Curiosity’s laboratory, would hit the powdered
rock with X-rays to examine its mineral structure and to reveal the basic
composition of the rock. Further, the temperature under which it formed and
even the acidity of water that may have altered the rock. Then, the sample runs
to the Sample Analysis at Mars instrument suite (SAM), which will use a mass spectrometer
to look at elemental abundances and perhaps even age-date the rock.
