This document summarizes the International Lunar Observatory Association's (ILOA) activities and missions. The ILOA plans to establish four lunar observatories (ILO-1 through ILO-X) starting in 2013 through 2018 to conduct astronomical observations and search for signs of life. They will image the Milky Way galaxy and search for Earth-like planets from the lunar south pole. The ILOA also aims to educate people worldwide about galaxy science through their Galaxy Forum events held in locations across the globe.
