Q.3 (vi) 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 ?

Best answer

Answer: (a) Non-functional satellites, spent rocket parts and fragments from collisions revolving around the earth; (b) they collide with satellites at high speed and damage them; (c) studies and experiments are being done to track and manage the debris.

(a) Space debris means all the useless objects revolving around the earth: satellites that no longer work, parts of launch vehicles left behind after launching, and pieces produced when a satellite collides with another satellite or object.

(b) The debris moves at very high speed (several km per second), so even a small piece can hit a working satellite or spacecraft and damage its solar panels, instruments or body. As the amount of debris grows, launching new spacecraft also becomes risky.

(c) Studies and experiments are being carried out to manage space debris — tracking and cataloguing the debris, avoiding collisions by changing orbits, designing launchers and satellites that produce less debris, and planning ways to remove the largest pieces from orbit.
