The Hubble Space Telescope has unquestionably shown the benefits of a space-based observatory, but having a telescope far from Earth offers the current conundrum of how to maintain such a facility. Since NASA?s Vision for Space Exploration is seemingly leading humans back to the moon, why not construct an observatory there? A group of scientists from the U.S. and Canada are exploring the option of building a Deep-Field Infrared Observatory in one of the moon?s polar craters. Although not quite a garden spot, this location would provide an excellent site for a very large and very unique spinning liquid mirror telescope.
