Seismic surveying is a geophysical method in which several geophones (vibration sensors) are placed in an array on the ground, such as a profile line. Subsequently, a seismic source generates seismic waves that propagate along the surface and in the subsurface. These waves are reflected and refracted at layer boundaries as well as at geological features, such as buried boulders and cavities. The surface wave (green) as well as the reflected (yellow) and refracted (blue) waves are recorded by the geophones. The arrival times of the waves are then evaluated and used to calculate the subsurface model.


There is also the possibility of using ambient noise, naturally occurring on the Moon or generated by machinery, such as a moving rover, to acquire geological data.


The strength of seismics lies in its wide range of applications. Geophone spacing and source intensity enable high-resolution near-surface measurements as well as deep measurements, such as crustal thickness, with low resolution.


This offers excellent opportunities for the ISRU industry and, furthermore, for planetary research.

Our setup consist of 3 units:


  1. Lunaphones: 45 wireless, three-directional geophones, robustly designed for the harsh environment of the Moon.
  2. Feeder mechanism: The rovers feeder mechanism is responsible for the placement and ground coupling of the Lunaphones. After the survey, the sensors will be collected and arranged in a new array for a new survey.
  3. Vibrational source: While other energy sources, such as falling weights or explosives, can achieve greater penetration depth, a controlled vibrational source can be beneficial, especially for shallow subsurface exploration. The vibration source has good repeatability, and the input waveform is well-known. Therefore, providing efficient data acquisition and good imaging quality.

This geophysical package will be implemented into an autonomous rover.

What about other geophysical methods?

Seismic measures mechanical parameters of geological features, which are especially relevant for construction and mining. Ground Penetrating Radar (GPR) or Electrical Resistivity Tomography (ERT) measures electrical properties, making them complementary methods, that contribute to even more detailed subsurface models.
