Launch Vehicles — Prelims Strategy

Prelims Strategy

For Prelims, focus on factual accuracy and comparative analysis. Create a mental or physical chart comparing PSLV, GSLV (Mk II & LVM3), and SSLV based on: 1) Number of stages, 2) Fuel types (solid, liquid, cryogenic), 3) Primary payload capacity (LEO, GTO), 4) Typical missions, and 5) Key engines (Vikas, CE-7.

5, CE-20). Memorize the full forms and key characteristics. Pay close attention to recent launches (2022-2024) – which vehicle launched what mission (e.g., LVM3 for Chandrayaan-3, PSLV for Aditya-L1, GSLV for INSAT-3DS).

Understand the significance of cryogenic technology and the RLV-TD program. Practice MCQs that test your ability to differentiate between the vehicles and identify correct statements about their features and applications.

Don't forget the Satish Dhawan Space Centre as the launch site. Focus on the 'what' and 'how' aspects.
