NASA's Curiosity Mars rover is snapping pictures of something unlike anything it has encountered before
In December, the rover reached a new territory called Bagnold Dunes, which is rich with one of Mars' most iconic landscapes: dunes.
The Bagnold Dunes are on the northwestern flank of Mount Sharp, a mountain at the center of Gale Crater.
Now, the rover is scooping up samples of the grains and offering an unprecedented view and examination of what they're made of.
