ISRO Launch Vehicle Update: What Aspirants Should Know

A summary of recent Indian Space Research Organisation launch developments relevant for UPSC, SSC, and Railway general science sections.

Overview

ISRO’s ongoing launch vehicle programs continue to be a recurring current affairs theme across UPSC Prelims, SSC, and Railway general awareness sections.

Exam-Relevant Points

  • Know the difference between PSLV (Polar Satellite Launch Vehicle) and GSLV (Geosynchronous Satellite Launch Vehicle) by orbit type and payload capacity.
  • Track ISRO’s human spaceflight program (Gaganyaan) milestones, as they are frequently referenced in current-year papers.
  • Be familiar with the launch site: Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.

Questions often combine a current event (a recent launch) with static facts (orbit types, previous missions, ISRO’s founding year — 1969, under Vikram Sarabhai). Build a running note connecting each new launch to its mission family.
