    Read the following passage and answer the questions given below: Space Debris and its management In addition to the artificial satellite, some other objects are also revolving around the earth. It includes, non-functional satellites, parts of the launcher detached during launching and debris generated due to collision of satellite with other satellite or any other object in the space. According to one estimation mode in 2016, there are about 2 crore pieces of length more than 1 cm, revolving around the earth! All this is nothing but the debris in space. This debris can be harmful to the artificial satellites. It can collide with these satellites or spacecrafts and damage them. This debris is increasing day by day. Soon, it will be difficult to launch new spacecrafts. It is, therefore, very essential to manage the debris. Some studies and experiments are being done with this in view. (a) What is meant by space debris? (b) How it can be harmful to the artificial satellites? (c) What efforts are being taken to manage it?
