Four stops' worth of sand from Curiosity's second Bagnold campaign
During early 2017 Curiosity stopped at four positions within the southern Bagnold dune field to investigate how the sand varied from place to place in the dune system. All four of these images are shown at the same scale; each shows an area about 13 millimeters across. Top left: Stop 1, sol 1603. Top right: Stop 2, sol 1618. Lower left: Stop 3, sol 1637. Lower right: Stop 4, sol 1650. Be aware when comparing the four images that each was taken under different solar illumination conditions, making color comparisons difficult.
