BRIEF DESCRIPTION
42.3_S_136.5_E
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 obtained from wikipedia.org. Section 149 and this directory was created by Fran Ridge and Ned Haskin of The Lunascan Project).
