LOLA: Moscoviense

Mare Moscoviense (GSFC - LOLA Image of the Week, June 14, 2010) is one of the few large maria located on the far side of the Moon.

LOLA data reveal the lowest point inside Titov crater to be about 2.7 km below the lunar datum. In contrast, the highest point on the rim of the basin rests about 3 km above lunar datum.

The total relief for the basin surrounding Mare Moscoviense is 5.7km. Although there are just as many impact basins on the lunar far side as the near, the extensive lunar volcanism seen on the near side is lacking on the far side of the Moon [NASA/GSFC/LOLA].

The spectacular Moscoviense Terrain Camera image from 2008, returned by Japan's first lunar orbiter Kaguya (SELENE-1). The yellow arrow indicates the location of a new and distinct kind of lunar rock discovered from data returned by India's first lunar orbiter Chandrayaan-1. The story from April 12 can be read here [JAXA/SELENE].

Stepping back from the false-color data in the LOLA Image of the Week, at the top, "bright is equal to relative height" in this look at Moscoviense in the global-scale, low-resolution LOLA data available through the Planetary Data System. Titov is just visible, and unlike visible imagery of the area, the multi-ringed nature of this impact basin is clearly visible along with a strong indication that the original inner ring may have been partially inundated with intrusive molten material, probably from within the Moon after it's original formation The obliquity of the "impact-forming event," retained in its present 'rectangular' shape also appears to have been a part of the formation from the instant it formed [NASA/GSFC/LOLA].
