The Moon - Rupes Altai and Crater Piccolomini - 2020-09-06 0505 UTC
Rupes Altai is the southern segment of the outer rim of the Nectaris impact basin. The escarpment extends from left center to bottom center of the image, casting a shadow onto the lower terrain to its north.
Captured along with Crater Piccolomini under a low Sun angle, the immense size of the impact basin and the tremendous energy of the impactor are readily apparent.
