Abstract: The number of different space debris on the orbits around the earth has gotten more and more attentions. These debris pieces put spacecraft in a dangerous place. We built a model based on the problems of the space debris¡¯ removal, discussing the cost of the three common methods (ground-based laser removing, water jet cutting and net-capture) for removing the debris. First we used the Monte Carlo to simulate the space debris¡¯ number and speed. Then we built models for the three common methods respectively, explored the removing efficiency of different size of debris and their cost for removing a unit volume of the debris. Finally we find that The laser removing method is suiTable for medium-sized debris with the diameter less than 10cm, the water jet method is suiTable for large-sized debris with the diameter within 10cm and 1400cm, the net-capture method is suiTable for super-large-sized debris with diameter bigger than 1400cm. Also, we analyzed the advantages and shortcoming of each method.
