Scientific paper

The lunar surface has historically been considered an optimal site for a broad range of astronomical telescopes. That assumption, which has come to be somewhat reflexive, is critically examined in this paper and found to be poorly substantiated. The value of the lunar surface for astronomy may be broadly compelling only in comparison to terrestrial sites. It is suggested here that the development and successful operation of the Hubble Space Telescope marked a turning point in the perception of value for free-space siting of astronomical telescopes, and for telescopes on the Moon. As the astronomical community considers the scientific potential of the Vision for Space Exploration (VSE) and the return to the Moon in particular, it should construct a value proposition that includes the tools, technology, and architecture being developed for this return, as these can well be seen as being more astronomically enabling than the lunar surface itself - a destination that offers little more than rocks and gravity. While rocks and gravity may offer astronomical opportunity in certain scientific niches, our attention should be focused on the striking potential of human and robotic dexterity across cis-lunar space. It is this command of our environs that the VSE truly offers us.
