Abstract
Current thinking about the Moon as a destination has revitalized interest in lunar astronomical observatories. Once seen by a
large munity as a highly enabling site, the dramatic improvement in capabilities for free-space observatories prompts
reevaluation of this interest. Whereas the lunar surface offers huge performance advantages for astronomy over terrestrial sites, free-
space locales such as Earth orbit or Lagrange points offer performance that is superior to what could be achieved on the Moon.
While astronomy from the Moon may be cost-effective once infrastructure is there, it is in many respects no longer clearly enabling
compared with free space.
