==Brownish hue of the lunar surface==

The brownish coloration of the lunar surface, which is frequently seen in orbital photographs of the Moon with Earth's light bluish colored crescent in the background, is mentioned in the article "To the Mountains of the Moon" ([[Apollo 15]]) by [[Kenneth Weaver|Kenneth F. Weaver]], in the February 1972 issue of ''[[National Geographic]]'', pages 255–257. It is also seen in [[Carl Sagan]]'s book ''Cosmos'' (1980), Chapter 4: '"Heaven and Hell", page 84: orbital lunar photograph AS12-47-6890 (Magazine V), made during the mission of [[Apollo 12]] in November 1969, showing the region of the northwestern section of crater [[Pasteur (lunar crater)|Pasteur]], on the eastern part of the Moon's farside.

A comparable photograph to Artemis II's ''Earthset'' is seen in Harrison H. Schmitt's article "Exploring Taurus-Littrow" ([[Apollo 17]]), on page 307 in the September 1973 issue of ''National Geographic''.
