An ultra-long-wavelength radio telescope on the far side of the Moon has significant advantages compared to Earth-based and Earthorbiting telescopes, including

(1) Conducting observations of the Universe at wavelengths longer than 10 meters (i.e., frequencies below 30 MHz), wavelengths at which critical cosmological or extrasolar planetary signatures are predicted to appear, yet cannot be observed from the ground due to absorption from the Earth’s ionosphere; and

(2) The Moon acts as a physical shield that isolates a far-side lunar-surface telescope from radio interference from sources on the Earth’s surface, the ionosphere, Earth-orbiting satellites, and the Sun’s radio emission during the lunar night. We propose the design of a Lunar Crater Radio Telescope (LCRT) on the far side of the Moon.
