To Great Depths

This image from eastern Hellas Planitia shows some of the unusual features on the basin floor. These relatively flat-lying “cells” appear to have concentric layers or bands, similar to a honeycomb. This “honeycomb” terrain exists elsewhere in Hellas, but the geologic process responsible for creating these features remains unresolved.
