Serenitatis Basin

Serenitatis Basin

(si-ren-ă-tah -tis) One of the youngest lunar basins, formed 4000 million years ago and filled with mare lavas from at least 3800 million years ago to produce the circular Mare Serenitatis (Sea of Serenity). The Mare has striking color contrasts and numerous rilles and wrinkle ridges. It was visited by Lunokhod 2 and the margins sampled by the crew of Apollo 17.
