The launcher's mission is to place a payload into orbit. To do this, the launcher must impart potential and kinetic energy to the payload so that it can maintain orbit. Indeed, the specific energy of a body in an elliptical orbit (figure

) around the Earth with a semi-major axis of
is the sum of kinetic and potential energy and verifies the following equation :
