Space junk or space junk any useless artificial object orbiting the Earth, it consists of things as varied as large remains of rockets and satellites old, leftover from explosions or rocket components remains as dust and small particles of paint. Space debris has become an increasing concern in recent years, since collisions at orbital velocities can be highly damaging to functioning satellites and can also produce even more space junk in a process called Kessler Syndrome. The International Space Station is shielded to minimize the damage due to this hazard.
Thesis Statement
To figure out the impact of space trash on the planet earth, whether space trash is injurious to human beings or has no effect.
Discussion
The group of small trash is composed of objects with a diameter less than 1 mm and weighing less than 1mg. The number of objects of this type is considerably large. The knowledge we have of this garbage comes mainly from the observation teams returning to Earth. The disruptive forces affecting this garbage more intense than the previous two types form (Punnakanta, 2012). Such impacts can alter the thermal protective layer and produce a failure in the systems of the ship and also the collision frequency is very high, for example in the 20 meter square of solar panels Hubble telescope more than 700 small craters, and the probability of collision with the ISS 1 every 10 days is estimated.
Another aspect to consider is the speed you can get. To get an idea, if we look at the LEO orbit, the relative velocity between objects is about 10 km/s, so an object about 80 gr. has a kinetic energy equivalent to the explosion of 1 kg of TNT. Another example: a 400 km. high paint particle 1 mm. diameter can reach up to 6 m / ...
