FIELD: aviation.
SUBSTANCE: spacecraft (SC) comprises at least one rocket propellant main tank, main drive motor, powered by a rocket propellant from the main tank, and a deorbit device. A deorbit device comprises a detonation engine powered by a rocket propellant from the main tank. A spacecraft launch vehicle comprises at least one stage formed by the noted spacecraft. In the spacecraft deorbit way the deorbit action is carried out after the main drive motor stoppage with the application of the detonation engine fueled by a propellant from the main tank under a pressure less than or equal to 10 bar. In the spacecraft deorbit way, that forms a deorbit device stage, the mentioned stage is detached from a launch vehicle after the main drive motor stoppage.
EFFECT: guarantee of the spacecraft deorbit with the application of the propellant from the main tank and, hence, spacecraft weight-saving.
