tóng-àn:Mare Moscoviense - Clementine.jpg

English: en:Mare Moscoviense sits in the Moscoviense basin.Like Mare Marginis, this mare appears to be fairly thin. However, it is clearly centered within a large impact basin. It is also much lower than either the outer basin floor or the farside highlands. The great depth of this mare beneath the nearby highlands probably explains why mare units are so rare on the lunar farside. Very few basins on the farside were deep enough to allow mare volcanism. Thus, while large impact basins are found on both the nearside and farside, large mare are mostly found on the nearside. Mare lavas apparently could reach the surface more often and more easily there. The basin material is of the Nectarian epoch, while the mare material is of the Upper Imbrian epoch. The crater Komarov is seen to the southeast of the mare. You can just make out the crater Titov in the northern regin of the mare.
