Daedalus is a prominent crater located near the center of the far side of the Moon. The inner wall is terraced, and there is a cluster of central peaks on the relatively flat floor. Because of its location (shielded from radio emissions from the Earth), it has been proposed as the site of a future giant radio telescope, which would be scooped out of the crater itself, much like the Arecibo radio telescope, but on a vastly larger scale.
The crater is pictured in famous photographs taken by the Apollo 11 astronauts. In contemporary sources it was called "Crater 308" (this was a temporary IAU designation that preceded the establishment of far-side lunar nomenclature).

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Daedalus crater.
