Lunar maps created by Professor Spencer Titley in the 1960's and news clippings about the maps and about Titley's work with US astronauts from the same era are now displayed on the fifth floor of the Gould-Simpson Building. A clipping dated April 22, 1964, quotes Titley: "I figure my work, which began last summer, keeps us in contact with the Apollo project."
To help select a landing site for Apollo spacecraft and to further our understanding of the moon, Spencer Titley spent many nights in the mid-1960's observing the moon through Kitt Peak's solar telescope and creating lunar maps. One map of an area approximately the size of Arizona, took Titley 25 nights to create, relying on shadows to help him pick out the moon's features. Then, in May of 1964, six US astronauts joined Titley and two astrogeologists from the U.S. Geological Survey to learn about Titley's observations. In an newspaper interview that year, Titley said, "There is no reason to believe that there aren't the same types of rocks as we have on Earth, but conditions are very different on the moon as so we can't be sure at what we are looking." To see the display, visit the fifth floor of the Gould-Simpson building west of the elevators.
