18 | MOONSHOT AT 50: ANNIVERSARY Premium supplement to the Arizona Daily Star Sunday, December 16, 2018 Mapping the Arizona scientists played major role in locating lunar landing sites

BY MIKAYLA MACE Arizona Daily Star n 1961, when President John F. Kennedy announced the would land a man on the moon by the end of the decade, modern lunar and planetary science was still in its infancy. Its birthplace? The University of Arizona in Tucson. IThe story of the moon land- ing, which occurred nearly 50 years ago, wouldn’t be complete without the endeavors of a team led by Gerard Kui- per, who became the director of the UA Lunar and Planetary Laboratory. Lunar atlases Even before the began with the launch of Soviet satellite Sput- nik in 1957, Holland-born Kuiper, direc- tor of the University of Chicago’s Yerkes Observatory in southern Wisconsin, was working on compiling the best im- ages of the moon at the time to create a photographic lunar atlas. Until that time, maps of the moon were drawn by hand and the names of the moon’s features were not agreed upon, said Timothy Swindle, the UA lab’s current director. At an astronomical conference in Dublin, Ireland, in 1955, Kuiper asked anyone interested in assisting him in his endeavor to create a moon atlas to reach out to him. Ewen Whitaker, then the director of the lunar section of the British Astro- nomical Association, was the only one to respond. Kuiper asked Whitaker to join him at Yerkes Observatory for a monthlong project. Whitaker left for the United States the day after Sputnik took to the skies. Then, Kuiper secured funding from the Air Force to complete the lunar atlas and Whitaker never returned to the United Kingdom, according to the 2016 doc- umentary “Desert Moon,” by science writer Jason Davis, which details the UA’s role in helping the United States reach the moon. While at Yerkes, Kuiper and his team published the first photographic lunar atlas. It was the most comprehensive photographic record of a planetary body ever published.
