| Bailly, the largest walled plain on the near-side of the Moon, has
a diameter over 303 km. Such a large formation is classified as a lunar
basin. It has an uneven floor with numerous craters. We had to rotate Steve
Massey's image (Fig. 1) 180 to align with the north-top of the acompanying
Lunar Orbiter 4 image (Fig.2). The black wedge at lower right of Bailly
in Fig. 1 is the blackness of space near the lunar south pole. Bailly takes
up all of the frame in the upper left image and the upper half of LO4 at
right. |
