Brief

Mare Crisium, or the "Sea of Crisis", is always an awesome sight. It covers four Lunar sections: 26,27,37,38 . Resembling a giant crater, this feature is 570 km across and is a lunar basin of impact origin. Long ago the floor was submerged under thick layers of lava. Its oval appearance to us is somewhat caused by its location close to the eastern limb, but its actual shape IS ellipsoid in the horizontal direstion. The overhead Lunar Orbiter view shows more detail. We "corrected" the image of Crisium from LO4 to show the actual shape.
