This week's Question: Driven by a $30 million prize put up by Google, more than two dozen teams have signed up for a competition to become the first private venture to land on the Moon. That means spacecrafts could be heading out within a few years, and many entrepreneurs are developing possible ideas that could take commercial advantage of Earth's neighbor. Some say that the endeavors are too expensive and the market is uncertain at this point, while others, including a former NASA computer scientist turned entrepreneur, say that the numerous potential Moon business, from exclusive video feeds to lunar lander trips, present "probably the biggest wealth creation opportunity in modern history." Do you agree? Is there money in the moon?
