A Basin Quest

image by " rel="nofollow Philippe Tosi, FRANCE-Nîmes

Near the middle of this scene is an ill-formed smooth area, not as dark as the Lacus Spei mare material at upper right.
The light-hued material has a name, Lacus Temporis, and occupies the central area of a 350 km wide depression. At
least that is what LPOD " rel="nofollow reported in 2004, and there have been little additional analyses of this putative small impact
basin. But Harry Hiesinger and his crater-counting colleagues have " rel="nofollow estimated that the lavas of Lacus Temporis erupted
between 3.62 and 3.74 b.y. ago. I imagine that the new LRO topographic data can much better define the size and depth
of the supposed basin that in 2006 was defined by the relatively coarse Clementine data. I imagine that by tomorrow
LPOD readers/contributers will have derived new information about this possible depression. Is there a Temporis Basin?
