FIELD: transport.SUBSTANCE: set of invention release to space engineering, particularly, to displacement in space using space resources and can be used for hitting the dangerous space objects (DSO) Proposed method comprises selecting the comet nucleus of one of mini-comet in orbits 6 approaching the Earth 3 as hitting space body (HSB). Rocket engine unit exploiting comet nucleus evaporant as a working medium is launched in space from the Earth and placed in orbit 8 to approach said HSB. Landing thereto is carried out at point 9. Said rocket engine unit is used to change said HSB from initial orbit 7 to trajectory 10 that ensures its collision with DSO 3 at point 11. This imparts to DSB the impulse that changes it from initial orbit 4 that implies the collision of the Earth at point 5 to safe orbit. Device to this end (not shown) comprises said rocket engine unit, snapper with comet matter evaporator, power plant (with solar concentrator and astronavigation device. With snapper penetrated into comet nucleus, evaporator sublimates nucleus volatile matters. Evaporated vapors are heated by solar concentrator effuse from rocket engine nozzle generates the thrust. Astronavigator sets required direction of thrust vector.EFFECT: power savings in mission, lower operating period of engines, higher reliability.4 cl, 2 dwg |
