The International Lunar Observatory Association (ILOA) plans to conduct astronomy and Earth observation from installations on the lunar surface. ILOA's goals include obtaining the first images of the Milky Way galaxy center from the Moon and studying Earth's atmosphere and weather. Future ILOA missions propose using locations like the lunar south pole for astronomy and establishing a human presence on the Moon in the 2020s. ILOA is working with space agencies globally on collaborative lunar science missions.
