The Smoothness of Schubert
Along the left side of this image, we can see a portion of the interior of the Schubert impact basin. Located in Mercury's southern hemisphere, Schubert was named for the early 19th century composer Franz Schubert. The basin's smooth floor resulted when the basin filled with lava, further evidence of past volcanism on Mercury.
