Mars Science Laboratory Mission Status Report (10.18.12)
PASADENA, Calif. -- NASA's Mars rover Curiosity has ingested its first solid sample into an analytical instrument inside the rover, a capability at the core of the two-year mission.
"We are crossing a significant threshold for this mission by using CheMin on its first sample," said Curiosity's project scientist, John Grotzinger of the California Institute of Technology in Pasadena. "This instrument gives us a more definitive mineral-identifying method than ever before used on Mars: X-ray diffraction. Confidently identifying minerals is important because minerals record the environmental conditions under which they form."
The sample is a sieved portion -- about as much material as in a baby aspirin -- from the third scoop collected by Curiosity as a windblown patch of dusty sand called "Rocknest." The rover's robotic arm delivered the sample to CheMin's opened inlet funnel on the rover's deck on Oct. 17.
