Penetrators are designed for a rough landing given that their head-end which is a penetrating probe with a solid-propellant rocket will penetrate deep in the lunar soil. Penetrator is a self-contained lander equipped with systems and devices that provide its motion after separating from the orbiter, the penetrating into the rock, as well as carrying out scientific research and the transfer of the scientific information to the orbiter for the data relay to Earth. The article deals with the impact of the engine operating on the specifications of the penetrator for the lunar soil study.
