Abstract: To date, there are several ways to determine the properties of the soil, but such methods are not suitable for studying the soil of an extraterrestrial object. However, there is a direction of ultrasonic drilling in order to study the properties of the soils of extraterrestrial objects, to detect valuable substances in the deep layers or to ensure the maximum speed of the channels to a given depth to secure the landing modules. The optimal implementation of ultrasonic drilling requires continuous acquisition of information about the process of impact on the soil with unknown properties. With the help of all the information obtained, it is possible to ensure an increase in the effectiveness of the ultrasonic exposure process. However, to date, the determination of the properties of the medium during the action of ultrasound is implemented only for liquids. The article proposes and develops a model of interaction of an ultrasonic piezoelectric emitter with the ground, taking into account the impact-contact nature of the impact. The analysis of the model allowed us to establish the relationship of the mechanical impedance of the soil with its properties. The revealed relationship can be used to determine the properties of previously unknown soil in real time during ultrasonic drilling to create drilling devices that guarantee optimal impact on a wide class of soils.
