LO-IV-188M Mees is the moderate-sized crater below center. The shadows make it appear that it has a convex floor. Touching Mees on the north is 85-km Mees Y. The dark mare region on the floor of Mees Y (mentioned by Danny Caes) is clearer in a high Sun Clementine view. Straddling the east rim of Mees Y is 36-km Mees A. The other named satellite features in this view are 26-km Mees J (to the southeast of Mees), 19-km Sundman V (beyond Mees J in the lower right corner) and 24-km Nobel B (touching the left margin in the upper left corner). The remaining features are not named.

Additional Information

  • From the shadows in LO-IV-188M, the height of the east wall of Mees ranges from about 1800 m in the north to 3000 m in the south. Mees Y appears to be about 3500 m deep (where its rim is not broken by Mees A). The off-central peak of Mees Y is 1700 m tall. - JimMosher Dec 16, 2007
  • On the floor of Mees Y is a dark Lacus-like spot. It's about the same size as the three named Lacus'es on the Moon's far side: Lacus Luxuriae (near Buys-Ballot), Lacus Oblivionis (near Sniadecki), and Lacus Solitudinis (near Bowditch). The dark spot on the floor of Mees Y is seen on the Clementine photographs which occupy the lower margin of LAC 54 and the upper margin of LAC 72 in the Clementine Atlas by Ben Bussey and Paul Spudis (pages 108 and 144). It is also seen on photographs made by several of the Russian ZOND probes, such as ZOND 8: Frame X2. On this photograph, the dark spot on the floor of Mees Y is seen "rightward" of Mare Orientale, and "above" the Eddington/Russell/Struve complex, which is located on the most western part of Oceanus Procellarum. Mees Y is not unique: a number of the Moon's other craters have dark mare patches on their floors. Schlüter is a well-known and similar example. - DannyCaes Dec 16, 2007
  • The somewhat elongated dark lacus-like spot of Mees Y is also noticeable in a remarkable view of the moon's western hemisphere, composed of LRO frames, detectable to the lower right of crater Ohm's chevron shaped ray system, see LPOD Fictitious Moon.
  • According to Wikipedia, Lunar Orbiter 3 impacted northwest of Mees (14.3° North/ 97.7° West).


  • Named for Charles Edward Kenneth Mees (1882-1960), a British-born pioneer in the science of photography. According to the IAU citation he organized the Eastman Kodak Research Lab and directed its studies on photographic processes, panchromatic plates and light filters for photography. This research led to development of the high-sensitivity emulsions used in much of 20th century film-based astronomy.
  • Mees was in the long list of farside names approved by the IAU in 1970 and published in Menzel, 1971.
  • Lacus Mees (D.Caes's unofficial name for the low-albedo spot Mees Y, just north of Mees).
  • Rima Mees Y (a dedicated rille seeker's unofficial name for the sinuous rille slightly north of Mees Y, see: ) (this sinuous rille is not included in Debra Hurwitz's Atlas of Lunar Sinuous Rilles).
