Description
English: en:Mare Tranquillitatis sits within the Tranqillitatis basin. The

mare material within the basin consists of basalt in the intermediate to young age group of the Upper Imbrian epoch. The surrounding mountains are thought to be of the Lower Imbrian epoch, but the actual basin is probably Pre-Nectarian. The basin has irregular margins and lacks a defined multiple-ringed structure. Theirregualr topography in and near this basin results from the intersection of the Tranquillitatis, Nectaris, Crisium, Fecunditatis, and Serenitatis basins with two throughgoing rings of the Procellarum basin. Mare Serenitatis is seen in the upper left of the photo below. Palus Somn, on the northeastern rim of the mare, is filled with the basalt that spilled over from Tranquillitatis. This mare also served as the landing

site for Apollo 11, the first manned landing on the moon.
