The Curiosity rover has been busy the last few days scooping up soil samples. The first two samples were emptied back onto the ground, due to possible contamination. A small portion of the third scoop was delivered the the rover's CheMin instrument for analysis. Watch this video of the rovers scoop vibrating to level out the soil sample.
NASA - Mars Soil Sample Delivered for Analysis Inside Rover: "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.
The rover's Chemistry and Mineralogy (CheMin) instrument is analyzing this sample to determine what minerals it contains.
"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.""
