Five months before Apollo 11 touched down on the surface of the moon in 1969, National Geographic published a supplement with exhaustive mapping of the lunar surface, including prospective landing locations. Producing the map, the first to show both sides of the moon in a single sheet, was a monumental task. Below, the cartographic staff built this ingenious rig, with a 40-inch globe representing the moon, to fix the exact position of the thousands of features, with precise latitudes and longitudes. https://bit.ly/2SxtJDj #moon #eclipse #lunereclipse #explorer #islandexplorerglobal https://www.instagram.com/p/B6nMzOijxFd/?igshid=16p3xaoy63mp3
