Dark side of the Moon: surveillance scope (science documentary).

John Michael Godier speaks with Saptarshi Bandyopadhyay about his cunning plans for putting a radio telescope inside a crater on the dark side of the moon, in this twenty-minute-long video.

An ultra-long-wavelength radio telescope on the far-side of the Moon has tremendous advantages compared to Earth-based and Earth-orbiting telescopes.

A Lunar Crater telescope can observe the universe at wavelengths greater than 10m (i.e., frequencies below 30MHz), which are reflected by the Earth’s ionosphere and are hitherto largely unexplored by humans.
