As a result of the near 5000 launches of communication, weather forecast, television and navigation satellites since the start of the space age, result with the potentially damaging space debris that orbits Earth. Scientists estimate the total number of space debris objects in orbit to be around 29,000 for sizes larger than 10 centimeters, 670,000 larger than 1 centimeter and more than 170 million larger than 1 millimeter and like we learnt in the class as a result of their
