Physicists are proposing the use of permanently shadowed craters near the Moon’s south pole to host ultrastable lasers and precision optical instruments.

The region’s extreme cold and natural vacuum could create ideal conditions for advanced timing systems, lunar GPS networks, deep-space communication, and even gravitational wave detection.

Designed to support future Artemis missions, the project could transform the Moon into a scientific and navigational hub for long-term human exploration beyond Earth.
