Swiss researchers want to image Moon’s interior with fibre optics

Fast internet for the Moon? Not quite. Researchers at the federal technology institute ETH Zurich want to bring fibre-optic cables to the Moon in order to measure moonquakes precisely. +Get the most important news from Switzerland in your inbox Previous data on moonquakes comes from the Apollo missions of the 1970s. However, as ETH Zurich explained in a press release on Tuesday, these offer only a fleeting insight into the interior of the Moon. In the scientific journal Earth Space Science, the researchers present just one approach that could be used to easily measure earthquakes on the Moon: a small rover could roll out kilometre-long and very light fibre-optic cables on the lunar surface. According to the researchers, these cables work like thousands of sensors and register every tremor. The researchers are using DAS technology (Distributed Acoustic Sensing) for their project. This involves a laser sending light pulses through a fibre-optic cable. Seismic waves that cause the ...
