ISRO’s Launch Vehicles:

FeatureSSLV (Small Satellite Launch Vehicle)PSLV (Polar Satellite Launch Vehicle)GSLV (Geosynchronous Satellite Launch Vehicle)GSLV MK-III (Geosynchronous Satellite Launch Vehicle Mark III)
PurposeLaunch small satellites into low Earth orbit (LEO)Launch satellites into polar orbits and geosynchronous transfer orbitsLaunch heavier payloads than PSLV into geosynchronous transfer orbitIndia’s heaviest and most powerful launch vehicle for larger payloads into GTO and beyond
Payload Capacity to LEOUp to 500 kgUp to 1,750 kgUp to 2,500 kgUp to 10,000 kg to LEO
Payload Capacity to GTONot designed for GTO missionsUp to 1,425 kgUp to 2,000 kgUp to 4,000 kg
Stages3 solid stages4 stages (alternating solid and liquid)3 stages (solid, liquid, and cryogenic)3 stages (2 solid strap-ons, 1 liquid, and 1 cryogenic)
Launch HistoryIntroduced for cost-effective access to space for small payloadsPSLV has a long and successful launch history with numerous missionsGSLV has been crucial for launching the INSAT class of satellites but has seen many unsuccessful launches.GSLV MK-III is designed for future manned missions and heavier satellite requirements. All launches to date have been successful.
Notable FeaturesQuick turnaround and lower costsVersatile and reliable, with a high success rateIntermediate lifting capacity with indigenous cryogenic upper-stageCapable of carrying the Chandrayaan-2 orbiter, lander, and rover to the Moon
Development StatusRecently introduced, fewer flightsFully operational with a robust track recordOperational, with ongoing improvementsOperational, designated for high-profile missions like Chandrayaan-2 and Gaganyaan
