Schumacher is a lunar impact crater that lies in the northeast part of the Moon, just to the north of the larger walled plain Messala.
The rim of Schumacher forms an eroded ring that is broken along the western side by the flooded crater Schumacher B. There is a low terrace along the northwestern inner wall. The rim is also notched along the eastern side by a pair of outward bulges. The interior floor of this crater has been resurfaced by basaltic lava, and now forms a level, nearly featureless plain. The floor is somewhat darker in the western half, which the albedo in the eastern half matches the surrounding lunar terrain.
Schumacher and Messala are separated by a rough strip of terrain less than 10 kilometers across, and bisected by a pair of small, co-joined craters. The northern member of this pair lies across the southern rim of Schumacher, and intrudes into the interior floor.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Schumacher.

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
Birkhoff is a giant lunar walled plain that is located on the far side of the Moon, in the northern hemisphere. This formation is an ancient impact site that has been heavily eroded, and the surface reshaped by multiple craters in the interior and along the rim. The outer wall is bordered by the craters Carnot to the south, Rowland along the west rim, and Stebbins to the north. Just to the northeast is van't Hoff.
Boltzmann is an old lunar impact crater that is located along the southern limb of the Moon, in the vicinity of the south pole. At this location the crater is viewed from the side from Earth, and so not much detail can be seen. It is located to the north of the walled plain Drygalski, and to the west of the crater Le Gentil.
Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.
Birkeland is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. This crater is attached to the central waist of the oddly shaped Van de Graaff crater formation, and may partly account for that crater's figure-8 shape. To the southeast is the large walled plain Leibnitz.
Blanchard is a lunar impact crater that lies on the far side of the Moon, just behind the southwestern limb. It lies to the south-southwest of the crater Arrhenius, and northwest of Pilâtre. Further to the south is the rugged terrain to the north of the walled plain Hausen.
Messala is a lunar impact crater of sufficient dimension to belong to the category of impact features known as walled plains. It is located in the northeastern part of the Moon, close enough to the rim to appear significantly foreshortened. It was named by the IAU in 1935.
Clark is a lunar impact crater that lies in the southern hemisphere of the Moon's far side. It is located midway between the larger walled plain Van der Waals to the south and the similar-sized crater Pizzetti to the north. It is named for American astronomer and telescope maker Alvan Clark and his son Alvan Graham Clark.
d'Alembert is a large lunar impact crater located in the northern hemisphere on the far side of the Moon, to the northeast of the somewhat smaller walled plain Campbell. Astride the southwest rim of d'Alembert is Slipher. To the north is the crater Yamamoto, and to the south-southwest lies Langevin. This walled plain has the same diameter as Clavius on the near side, making it one of the largest such formations on the Moon.
Carnot is a large crater in the northern part of the Moon's far side. It was named after Nicolas L. S. Carnot by the IAU in 1970.
Chapman is a lunar impact crater that lies just beyond the northwest rim of the Moon, on the far side as seen from the Earth. It lies to the northeast of the crater Rynin, and southward of the large walled plain Poczobutt.
Cyrano is a lunar impact crater that lies on the far side of the Moon. It lies due east of the huge walled plain Gagarin, and to the north of the somewhat smaller crater Barbier.
Debye is a lunar impact crater that is located in the northern hemisphere on the Moon's far side, as seen from the Earth. It lies to the south of the crater Chappell, to the southwest of the walled plain Rowland, and to the east of D'Alembert.
Curie is a large lunar impact crater, much of which lies on the far side of the Moon as seen from the Earth. The western rim projects into the near side of the Moon, as defined by the selenographic coordinate system. However the visibility of this formation depends on the effects of libration, so that it can be brought fully into view or completely hidden depending on the orientation of the Moon. When visible, however, it is seen nearly from the side, limiting the amount of detail that can be observed.
Hooke is a lunar impact crater that is located to the northwest of the crater Messala, in the northeastern part of the Moon. It lies about a crater diameter to the southeast of the comparably sized Shuckburgh.
Faye is a heavily eroded lunar impact crater in the rugged southern highlands of the Moon. It is named after French astronomer Hervé Faye. It is attached to the northeastern rim of the crater Delaunay, with Donati located just a few kilometers to the northeast. It forms part of a chain of craters of increasing size to the southwest that continues with La Caille and ends with the walled plain Purbach.
FitzGerald is a large lunar impact crater on the far side of the Moon. It lies to the west-southwest of the crater Cockcroft, and about two crater diameters to the northeast of Morse.
Joule is a lunar impact crater that lies on the far side of the Moon. It is located to the north-northeast of the walled plain Mach. To the northwest of Joule is the crater Blazhko.
Koch is a crater on the far side of the Moon. It lies in the southern hemisphere, to the south-southeast of the walled plain Jules Verne. Attached to the northeastern rim of Koch by a neck of uneven terrain is the crater Lundmark. Less than one crater diameter to the south of Koch is Crocco.
Laue is a lunar impact crater that lies across the south-southwestern rim and interior floor of the huge walled plain Lorentz. This feature is located on the Moon's far side, just beyond the west-northwestern limb. Under conditions of favorable libration and illumination from the Sun, this area can be seen at a very oblique angle from the Earth.
