The Apollo 10 CSM Charlie Brown appears in the foreground of this photograph of 'Mount Marilyn' (upper left terrain feature), May 1969. Mount Marilyn was named by Apollo 8 astronaut Jim Lovell, for his wife, during the first manned mission to the moon in December 1968. The name 'Mount Marilyn' was unofficial until July 26, 2017, when the name was formally accepted by the International Astronomical Union.
