The invention relates to an aerospace system designed to put payloads into low and medium orbits. After taking off from an aerodrome, a plane comprising the launcher with the payload heads at cruising speed for the launching area, where it performs a dive; after reaching its maximum speed, the plane rotates. At the end of the rotation, the angle of attack is modified in order to obtain conditions close to zero gravity; the launcher is then released from the plane, in such a way that it lags behind the plane, is subsequently rotated at 10-30 DEG with respect to the vertical plane, and the sustainer motors are turned on. The launcher is released when the parameters of the trajectory correspond to the initial conditions that allow the launcher to put into orbit a maximum payload. During the release of the launcher, the plane is stabilized in an inertial coordinate system.
