Asteroid Defense Using Cleavage Agents
By Yu Jiang
Traditional asteroid defense uses methods such as high-speed collisions or explosions, which require relatively large amounts of energy. However, it takes a long time to use Solar sail or other electric propulsion to drag asteroids away. It is necessary to study new methods of asteroid defense. This article proposes the use of cracking agents for asteroid defense. Firstly, the spacecraft drilled holes on the surface of the threatening asteroid, and then injected non explosive cracking agents into the holes. Under the action of cracking agents, asteroids will undergo non explosive fracture and disintegration. It can effectively achieve the goal of asteroid defense, without causing severe explosion effects and potential secondary disasters. Before actual asteroid defense, numerical simulations were conducted on the required drilling positions and number of holes to help us design asteroid defense missions.
