(concept for a dish radio telescope in a lunar crater)
The LCRT (for Lunar Crater Radio Telescope) is a concept to
place a radio telescope on the far side of the Moon,
using a lunar crater (somewhat like Arecibo Observatory used the landform
to support its antenna). The concept is undoubtedly fluid at
this point, one version being a 350-meter reflector dish, and
a 4.7-MHz-to-47-MHz frequency range, with a reflector dish
suspended within a crater of on the order of 1 km in diameter.
Another concept is for a 1-km aperture dish within a larger crater.
Such a telescope would have the advantage of elimination of
artificial radio frequency interference (RFI), an advantage especially beneficial to
low frequency radio astronomy.
