The interesting thing here is that this looks like an “expanded crater” (a crater that widened as ice went away) but other pits here look like “scalloped depressions” (also due to ice sublimating, but without the crater). Our science rationale for this target is how the shapes and depths are different depending on whether there’s a crater to begin with.
