Lunar liquid mirror telescope
In this speculative illustration, a giant liquid mirror telescope 1 kilometer wide (6 tenths of a mile) and 1 kilometer tall lies nestled in an approximately 1 kilometer wide crater near the Moon's south pole. In the foreground is a kind of lunar city for human habitation composed of pressurized and radiation-hardened living units. On the upper right are landing pads for transports arriving to and departing from the lunar surface.
mirror telescope is a Newtonian reflecting type telescope that employs a
reflecting liquid as the primary mirror. A concept first identified 300
years ago by Isaac Newton himself, the reflecting liquid assumes the proper
paraboloidal shape by rotating the container the liquid is in. On Earth
working liquid mirror telescopes have been created with diameters up to 20
feet using mercury metal as the reflecting liquid. One limitation is that
liquid metal mirror can only be used in zenith telescopes that look straight
up at the sky, so it is not suitable for investigations where the telescope
must remain pointing at the same location of space.
