LCRT

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. Such a telescope would have the advantage of elimination of artificial radio frequency interference (RFI), which is especially beneficial to low frequency radio astronomy.
