Concept of operations for building LCRT.

The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts to create an ultra-long-wavelength (that is, wavelengths greater than 10 m, corresponding to frequencies below 30 MHz) radio telescope inside a lunar crater on the far side of the Moon.[a]


If completed, the telescope would be the largest filled-aperture radio telescope in the Solar System at 1 kilometre (1,000 m; 3,300 ft; 0.62 mi) in diameter.[1][2]
