Scientists Want to Lay Fiber Optic Cable on the Moon

Seismologists are exploring the idea of deploying a fiber seismic network on the Moon, similar to Earth, to detect quakes on the lunar surface. In a new study, the team of researchers has underlined the challenges that need to be overcome to ensure this deployment. The team has tested a hypothetical network using artificial seismograms created from data collected by seismometers placed on the Moon’s surface.

These seismometers were placed on the Moon by Apollo-era astronauts between 1969 and 1976, which has sent back valuable data. The equipment detected thousands of seismic events over seven years on the near side of the Moon. Analysis of data has revealed that a fiber seismic network could identify the kind of seismic waves that would provide more information about the Moon’s deep core structure.

While the seismometers revealed activity on the near side of the Moon, the far side, the one not visible to Earth remains an enigma. Scientists want to know what explains the mysterious lack of moonquakes detected on the far side of the Moon. And why did the Apollo seismometers detect moonquakes occurring 700 to 1100 kilometers below the surface, at a depth on Earth where heat and pressure would lead to plastic deformation instead of the brittle break of an earthquake? To answer these questions, scientists want more seismometers on the surface of the Moon.

The silent world of the Moon at times experiences rumbles deep within its surface and scientists want to know what triggers these events. They have a plan in the works. With the Artemis mission picking up pace, the prospect of laying fiber optic cable on the Moon could soon become a reality.
