These are some mountains and craters near the #lunar south pole casting shadows near the dividing line between night and day. The image was made at about 06:00 UTC on 24th February, just a few hours before the #Moon was full.
Close to the center of this image is the crater Malapert A, where the #Odysseus spacecraft has come to rest on its side. The pole itself is 300 km further away in the darkness.
