To the north in this image is Mare Imbrium ("Sea of Showers"). Three lunar missions have landed here: the Soviet Luna 17 in 1970, the American Apollo 15 in 1971, and the Chinese Chang'e 3 in 2013. To the south in this image is Mare Insularum ("Sea of Islands").

Separating the two seas is the mountain range Montes Carpatus, named after the Carpathian Mountains in central and southeastern Europe.
