PIA13468: Pits, Picasso, and Mercury's History

Pits, Picasso, and Mercury’s History


The crater pictured in the center of this image was recently named Picasso , in honor of the Spanish painter and sculptor Pablo Picasso (1881-1973). This crater, first imaged during MESSENGER's third Mercury flyby , has drawn scientific attention because of the large, arc-shaped pit located on the eastern side of its floor. Similar pits have been discovered on the floors of several other Mercury craters, such as Beckett and Gibran . These pits are postulated to have formed when subsurface magma subsided or drained, causing the surface to collapse into the resulting void. If this interpretation is correct, pit-floor craters such as Picasso provide evidence of shallow magmatic activity in Mercury's history.
