The moon is our nearest celestial neighbor, the source of Earth’s tides and eclipses, and the constantly changing illuminator of the night skies. It likely formed by a giant asteroid impact in the early eons of the solar system and is said to be geologically "dead", but it may be a source of outer-space resources and may become the first human outpost in space. Along with the Apollo missions, all these and more are features of our moon and will be the topics to study as we look out at our solar system and join our closest companion in the grand celestial dance.
