Preparation
Prior to leaving, a lot of planning was done. This included everything from insignia, call signs, and souvenirs to site selection. On February 8, 1968, five prospective landing sites were chosen and publicized. Years of investigation employing high-resolution images of the moon’s surface led to this discovery. A set of requirements was established. For instance, an ideal day would reduce the temperature fluctuations that a crew member would be exposed to, as well as a site with fewer craters.
