Following the SELENE mission, scientists proposed that volcanism in Mare Moscoviense was active for at least ~1.5 Ga following the formation of the Moscoviense basin,[4] but the formation of the mare as the result of a meteorite cluster impact, rather than from volcanism, has also been proposed based on the energy required to melt the lava in Mare Moscoviense.

[5] At the center of the basin (or the southwest portion of the mare) is a mascon, or gravitational high.

[8] Mare Moscoviense was discovered in 1959, when the first images of the far side were returned by the Soviet spacecraft Luna 3.

The crater Titov is in the northeastern region of the mare, and Tereshkova lies along the northern edge.

The floor-fractured crater Komarov lies on the southeast edge of the mare.
