"Glenelg was conceptually a point that represented the three areas," John Grotzinger, project scientist for MSL at the Jet Propulsion Laboratory, told reporters today. "As part of understanding how those interrelate, we consider ourselves now to be in the promised land."
Now the rover's Chemistry and Mineralogy (CheMin) instrument is analyzing a scooped sample of dirt from a site inside Glenelg called Rocknest. This is a major step for the rover, whose ability to X-ray sand is a crucial part of its two-year mission.
To prepare, Curiosity rinsed its instruments with some dirt to ensure any Earthly contamination was removed.
In the process of scooping those mouthfuls, it spotted some bright material. One of the pieces turned out to be a piece of the rover itself, a shard of plastic that fell off but didn't cause any harm. But the other shiny things, including the object in the image above, are native to Mars.
