A Distinctive method of how to deflect an asteroid from the Population
Deflect-bot Hammer Probe; to change the direction of space rock with multiple impacts.
By Ismail Adil
Most of us are aware of the dangers of a deadly asteroid striking the earth. Some of us are thinking of how to avoid such a catastrophe. The concept in this article might explain one of the effective methods of how to deflect and divert those space rocks into another orbit.
Specially designed robotic space probe or Deflect-bot Hammer Probe might be the right candidate to do this job effectively. We may need to send a Deflect-bot Hammer Probe to land on an asteroid to deviate the asteroid’s direction. Once it lands on the asteroid, it has to be anchored and then ignite sparks to explode fuel inside its combustion cylinder to produce high pressure. This will create a force which gives an impact for the asteroid to move slightly. At the same time, there is a blasting disk flying off from the Deflect-bot Hammer Probe to balance the interaction to work it properly. This hammering process needs to be repeated for a multiple times to make a difference and to change the asteroid’s trajectory.
How does Deflect-bot Hammer Probe work?
Deflect-bot Hammer Probe is a kind of a robotic space probe lander with multiple legs as shown in the diagram (Fig.1). It consists of Combustion cylinder, Blasting disks, Fuel tank, Oxidizer tank, Ground plate, Control thrusters and other necessary modules. Combustion cylinder must be made of strong but light materials, enough to sustain at very high temperatures and pressures during combustion process. Combustion cylinder’s bottom end has to be fully closed and sealed together to connect the Ground plate. And the other end (top end) can be closed by using blasting disks as diagram indicates.
Deflect-bot Hammer Probe can be sent to an asteroid accompanied by another spacecraft. When spacecraft reaches the asteroid’s orbit, Deflect-bot Hammer Probe can be deployed to the proposed landing site from the mother ship for landing on the asteroid and has to be anchored well to the ground by using foot screws from its legs . Once the landing process is completed, it needs to fill fuel and oxidizer to the closed Combustion cylinder from the tanks and then ignite sparks inside the Combustion cylinder to explode. With the strong pressure, Blasting disk which is on the top end of the cylinder blasts off (fly away) due to the resulting exhaust gases and to balance interaction forces. At the same time, the Ground plate gives an equal force to the surface to push the asteroid on the opposite direction relative to blasting disk’s direction. Every time an explosion occurs in the Combustion cylinder, a new Blasting disk flies off and automatically need to replace with another new Blasting disk to the top end to continue this process until all the Blasting disks fly away. During this process, due to multiple impacts (force) to the ground, it helps to move the asteroid into another orbit.
The amount of force required to change the asteroid’s direction depends on mass, size, composition and shape of the asteroid and its orbit. So before building the Deflect-bot Hammer Probe,these facts have to be considered.
Note: Blasting disks can be made of special light weight material to reduce payload during the flight for the asteroid and to work efficiently during the hammering process.
Deflect-bot Hammer Probe is effective?
Deflect-bot Hammer Probe’s purpose is to deviate asteroids and other celestial bodies to prevent collision impact. In this concept, Deflect-bot Hammer Probe will not blast the asteroid; rather it will help to change its direction by hammering the asteroid with controlled impacts. And it uses its limited fuel quite efficiently; only during every blast it burns fuel to give a very high impact, rather than continuous propulsion, so this makes an efficient method to change the asteroid’s trajectory to avoid collision course to the Earth.
