6) What do you understand by space debris. Also, discuss some of the technologies that could be employed in future, to tackle the problem.(250 words)
Why this question
Scientists and researchers have been warning us time and again about the dangers posed by the space debris. Countries like US, Japan and Russia have shown their intent to tackle the problem. Besides, recently the RemoveDEBRIS satellite was launched, to test – for the first time – new technology aimed at capturing and deorbiting space junk. The issue is related to GS-3 syllabus under the following heading
Awareness in the fields of IT, Space, Computers, robotics, nanotechnology, biotechnology and issues relating to intellectual property rights.
Key demand of the question
The question wants us to express our knowledge of the meaning of space debris, their sources, what are the dangers posed by them and what are the technology options available to tackle the issue.
Discuss- we have to write in detail about all the key demands of the question- our understanding of the term and how can the issue be resolved.
Structure of the answer
Introduction- Give a brief definition of space debris and demarcate between natural and artificial debris.
- Enlist the sources of space debris- e.g Dead spacecraft, Lost equipment, Boosters, Weapons etc.
- Briefly discuss the threats posed by them. E.g to space-crafts, International Space Station, Kessler’s syndrome, collision with earth etc.
- Discuss in points all the relevant technologies. E.g ElectroDynamic Debris Eliminator; Solar sails; Space Debris Elimination (SpaDE) system; Laser Broom; Discuss each technology briefly. Also add, ending or sharply reducing the number of breakups of spacecraft and rocket bodies and, to a lesser extent, by reducing the amount of mission-related debris released in spacecraft deployment and operations; Deorbiting or accelerating the orbital decay of spacecraft and rocket bodies at the end of their functional lifetimes etc.
Conclusion- Mention that most of these technologies have not been successfully tested and launch of RemoveDEBRIS will significantly reduce the knowledge gap.
