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 (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][lower-alpha 1]

Lunar Crater Radio Telescope
Alternative namesLCRT
Location(s)far side of the Moon
Telescope styleradio telescope Edit this on Wikidata
Diameter350 m (1,148 ft 4 in)
Concept of operations for building LCRT

If completed, the telescope would have a structural diameter of 1.3 km, and the reflector would be 350m in diameter.[3][4][5] Robotic lift wires and an anchoring system would enable origami deployment of the parabolic reflector.[6]

History

A previous proposal put the proposed relector size at 1 km diameter.[7]

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.[2]
