Perhaps not mentioned in the LPI's list, but... Apollo 10 made two photographs of Joliot and nearby Lomonosov (AS10-27-3916, 3917). The captions below both frames are totally wrong, because those photographs don't show Ptolemaeus and Tycho!

Additional Information


  • Named for Jean Frédéric Joliot-Curie né Joliot (March 19, 1900 – August 14, 1958), a French physicist and Nobel laureate. While being a lecturer at the Paris Faculty of Science, he collaborated with his wife (the daughter of Marie Sklodowska-Curie) on research on the structure of the atom, in particular on the projection of nuclei, which was an essential step in the discovery of the neutron. In 1935 they were awarded the Nobel Prize for Chemistry.
  • The dark patches on the floor of this crater were known as Mare Novum in the original IAU nomenclature of Blagg and Müller (1935).
  • These patches were apparently noted in Kuiper’s Photographic Atlas of the Moon (1960); but they were more prominent in the Soviet Luna 3 photography, prompting the new name Joliot-Curie to be suggested by Russian scientists and to be included in the initial list of 18 far-side names somewhat hastily approved by the IAU in 1961. The list also included a newly named southern hemisphere crater called Sklodowska-Curie.
  • Joliot-Curie was next mentioned in D.W.G. Arthur’s 1964 report of changes introduced in the System of Lunar Craters, where it is stated that the name Mare Novum is being dropped and the name Joliot-Curie being added for a 142 km diameter crater whose floor includes the former Mare Novum. The report implies that this is a redefinition because the Russian name had been meant to be equivalent to Mare Novum -- that is, a name for the dark patches rather than for the surrounding crater -- even though the lack of the word "Mare" in the Russian name would suggest meant the crater. - Jim Mosher
  • In 1970 the IAU re-thought the problem of naming these craters in honor of the Curie family, because at that time it wanted to avoid features with similar-sounding names. It was decided to rename the present crater Joliot in honor of Frederic Joliot-Curie, and the southern hemisphere crater Sklodowska in honor of Marie Curie,. To honor Pierre Curie the new name Curie was assigned to a previously unnamed crater to the southwest of Sklodowska. It is curious that the 1970 IAU citation does not mention Irene Joliot-Curie, who was so closely associated with Joliot, and co-winner, with him, of the Nobel Prize. - Jim Mosher
