Smile for the Camera
The crater with the "smile" (the large crater toward the top of the image) is Al-Hamadhani, named in 1979 for the tenth century Iranian author Badi' al-Zaman al-Hamadhani. This crater was first imaged by Mariner 10, but MESSENGER's Wide Angle Camera (WAC) now offers us another view.
