NOVELTY - The engine has a laser mechanically fastened to a spacecraft, where laser beam of the spacecraft is directed to an optical system. The optical system is mechanically fastened to the spacecraft. The optical system is provided with radial mirrors. Square mirrors are mechanically fixed with a metal ring. The square mirrors are mechanically fixed to metal bars by the metal ring. The metal bars are mechanically connected to the metal ring in which flat mirrors are embedded. The flat mirrors are provided with radial or cylindrical sections that are covered with graphene layers. Each flat mirror is returned with reflecting surfaces. The metal bars are mechanically connected to the spacecraft. USE - Photographic HTS rocket engine.
