India’s space ambitions are soaring, not just in the sky—but in how we think about rockets.

Forget one-size-fits-all. ISRO uses four distinct launch vehicles; each built for a different job. SSLV? The sprinter. Built for quick, cheap small-sat launches with 72-hour turnaround. PSLV? The veteran. Launched 104 satellites at once, Mangalyaan, Chandrayaan-1. Still reliable, still busy. GSLV Mk II? The mid-weight champ. Uses India’s own cryo engine to put big comms sats in GTO. Then there’s LVM3; “Bahubali.” Can carry 8 tonnes to LEO. Human-rated. Took Chandrayaan-3 to the Moon. Designed for Gaganyaan. What’s the lesson? It’s not about the biggest rocket. It’s about the right rocket for the right mission. And India’s mastered that. For aspirants: know the payload limits, stages, orbits. SSLV (500kg LEO), PSLV (~3.8T LEO), GSLV (~2.25T GTO), LVM3 (4T GTO). Also: CE-7.5 vs CE-20 cryo engines. POEM. Vikas engine. Gaganyaan link. This isn’t just rocket science; it’s exam science.
