Roche is a large crater referred to as a walled plain
dominating Section 149 on the lunar Far Side. The prominent
crater Pauli lies across the southern rim of Roche, and the
outer rampart of Pauli covers a portion of Roche's interior
floor. (Notice the low ridge structure near the
midpoint of Pauli, and the remains of a ghost crater in the
southeastern part of the floor). To the north-northwest of
Roche is the crater Eotvos (out of frame and in Ridge
Section 150), and just to the west-northwest lies Rosseland.
The western rim of Roche has been somewhat distorted and
straightened. The rim as a whole is worn and eroded, with
multiple tiny craterlets marking the surface. The satellite
crater Roche B lies across the northeastern inner wall. The
interior floor of Roche is relatively level, but is also
marked by several small and tiny craterlets. A grouping of
these craters lies near the midpoint. Just to the northwest
of this grouping is a bright patch of high-albedo material.
Sections of the floor along the north-northwestern side have
a lower albedo than elsewhere, usually an indication of
basaltic lava flows similar to what fills the lunar maria.
The extent of this patch may actually be larger, but covered
with higher-albedo ejecta. A couple of Lunar Orbiter links
were found, but no Apollo images located. However, there was
interest shown in the crater Rosseland as demonstrated in
the LRO page listed below, as well as the crater Rosseland
and Pauli in the paper also listed below. (Credit: Some of
the information used in the section feature descriptions was

Project).
