Abstract :
Asteroids collide with many planet surfaces, most considerably Mars due to its proximity to the asteroid belt, creating craters on their surfaces. The impact of the hit is so high that it leads to the formation of micron-sized grain type dust particles which are the remnants of the collision. These particles are known as Cosmic dust. This dust is present in most parts in the atmosphere in large traces, dominantly near Mars and Earth, as the asteroid collisions are more prominent near these planets´ surfaces. Also termed as Interplanetary Dust, the density of these particles trapped in the Earth´s atmosphere range from 1g/cc to 3g/cc, having an average density of approximately 2g/cc. Coming to the dust´s chemical properties, they have molecular traces of Carbon Monoxide (CO), Silicon Carbide(SiC4), Amorphous Silicates(a-Si or a-Si), polycyclic aromatic hydrocarbons, water ice and polyformaldehyde. In spite of all these conclusions about the physical and chemical properties of the cosmic dust, the problem arises when these specks of dust collide with all the space ships and the man-made satellites sent into space, vaporize on the collision´s impact forming a kind of plasma.
