LOLA: Schrödinger Basin
Great photos and over view of this lunar feature at the link
NASA GSFC - Schrödinger (centered -75.0˚, 132.4˚ E), located on the lunar far side and within South Pole-Aitken Basin, is not visible from the Earth. Crater counts suggest that the basin is less than one billion years old, making it the second youngest impact basin on the Moon (the youngest being Orientale).
LOLA data reveal that the basin has approximately 3.3 km of relief from rim to floor. The basin’s inner ring is clearly visible, as are lunar rilles, smaller impact craters, and a volcanic cone (see arrow).
