This image of "moon tourists [discovering] the pleasures of this Moon beach," is from the 1988 book The Earth's Moon (Isaac Asimov's Library of the Universe).
Imagine seas on a terraformed Moon! By creating an atmosphere on the Moon, we could capture sunlight and turn the Moon into a celestial tourist trap. This would be fun, but many scientists feel it is more important to keep the Moon pretty much as it is. Then we could use it to help us better understand Earth and the cosmos.
