I work for a publishers celebrity cheap pantoprazole photographer worthless While Mars may be the ultimate destination, the moon is the ideal testing location for low gravity (not zero-g) processes and equipment. Clive Neal and Bill McKinnon provided an overview of what we've already learned from Apollo landings and the questions still remaining. The moon has already provided a vast source of information on the early history of the solar system. As Apollo samples are studied with new technology, researchers continue to make discoveries. Data from old robotic missions and recent orbiters has opened up as many questions as it has answered. One of the most intriguing questions for geologists is the issue of water or OH on the moon. Three different orbital missions have noticed some sort of release of volatiles containing mercury and possible water. If there is any thought of lunar colonies, a geophysical study that more accurately pinpoints the location of the magnitude 5 moon quakes already observed will be critical. Nobody wants to set up facilities on top of the local equivalent of the San Andreas fault.
