Researchers propose using permanently shadowed lunar craters to build highly stable optical lasers. These lasers could enable a GPS-like navigation system for spacecraft on the Moon and establish the first extraterrestrial atomic timekeeping signal. The extreme cold and vacuum of these craters would minimize vibrations and thermal expansion, allowing for unprecedented laser frequency stability. AI
