Lunar Crater Radio Telescope

The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts to create an ultra-long-wavelength (hereby wavelengths greater than 10 m – i.e., frequencies below 30 MHz) radio telescope inside a lunar crater on the far side of the Moon.[lower-alpha 1] If completed, the telescope would be the largest filled-aperture radio telescope in the Solar System at 1 km in diameter.[1][2]

Notes
  1. Radio telescopes on Earth can't probe the long-wavelength radio waves from the universe's Dark Ages, as the ionosphere reflect them through its layer of ions and electrons.[1]
