caption_attribution_description: English: en:Mare Australe is located in the southeastern hemisphere of the moon. It overlaps the near and far sides of the moon, and is 603 miles in diameter. The basin containing the mare is of the Pre-Nectarian epoch, while the actual mare material is of the Upper Imbrian epoch. Smooth, dark volcanic basalt lines the bottom of the mare. Notice the crater Jenner in the middle of the photo, this is an Imbrian crater that was later filled with mare basalt. Just to the left of Jenner is the crater Lamb.
context_page_description: Jenner is a lunar crater that is located within the Mare Australe. It lies just past the southeastern limb, on the far side of the Moon, and can be viewed from the Earth during periods of favorable libration and lighting. Nearly attached to the eastern outer rim of Jenner is the larger, flooded crater Lamb.
  This is a nearly circular crater with a sharp but somewhat irregular edge that has not been significantly eroded. There are some terraces, particularly along the southwestern inner walls, and some slumping along the southeastern rim. The interior floor has been flooded by basaltic lava, leaving a dark, level interior. There are no breaks in the exterior rim where the lava could have entered the crater, so it was presumably flooded from below. The floor is marked only by a few tiny craterlets. Surrounding Jenner is a rampart of ejecta that extends for over a half crater diameter in some directions.
