Concept of operations for building LCRT

The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts (NIAC) 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.[1][a]

The reason for building the LCRT on the far side of the Moon would be to avoid interference faced by radio telescopes on the Earth's surface.[2] The Moon would block many sources of radio interference originating on Earth, and would avoid the problems that come from Earth's ionosphere at long radio wavelengths.[3]

If completed, the telescope would have a structural diameter of 1.3 km, and the reflector would be 350m in diameter.[4][5][6] Robotic lift wires and an anchoring system would enable origami deployment of the parabolic reflector.[7]
