5. Explain the various kinds of satellite orbits initiated from Earth and analyse the potential risks related to unmanaged rocket re-entry into the Earth’s orbit. (250 words)

Difficulty level: Moderate

Reference: Insights on India

Why the question: 

The question is part of the static syllabus of General studies paper – 3 and mentioned as part of Mission-2023 Secure timetable.

Key Demand of the question:

To write about various types of orbits and issues associated with uncontrolled re-entry of rockets

Directive word:

Examine – When asked to ‘Examine’, we must investigate the topic (content words) in detail, inspect it, investigate it and establish the key facts and issues related to the topic in question. While doing so we should explain why these facts and issues are important and their implications.

Structure of the answer:

Introduction: 

Begin by defining an orbit.

Body:

First, write about different types of orbit for satellite launches from earth and their functions. Draw a small representative diagram of the same – Geostationary orbit (GEO), Low Earth orbit (LEO), Medium Earth orbit (MEO), Polar orbit and Sun-synchronous orbit (SSO), Transfer orbits and geostationary transfer orbit (GTO) and Lagrange points (L-points)

Next, in detail, write about the uncontrolled re-entries of rockets into the earth’s orbit and issues associated with it.

Next, write about the measures needed to overcome the above issues.

Conclusion:

Conclude with a way forward.
