Scientific Research — ISRO, DRDO and Major Indian Missions
Overview
Scientific Research—specifically India's space and defence organisations and their landmark missions—is a moderate-scoring topic in SSC GD that typically yields 2–4 questions per paper. This topic tests your awareness of recent satellite launches, missile programmes, major research centres and their roles, plus notable achievements like Chandrayaan, Mangalyaan and Gaganyaan. Questions often ask for organisation headquarters, mission years, names of missiles or satellites, and the purpose of a specific mission. Mastery here means remembering the **what, when and why** of each mission, not intricate technical details. Most questions are factual recall: "Which organisation developed BrahMos?" or "What was the primary objective of Chandrayaan-3?" Keep your focus on missions launched or announced in the last 5–7 years, as current affairs blend seamlessly with static GK in this domain.
Candidates often confuse similar-sounding missions (Chandrayaan vs Gaganyaan) or forget which body launched which satellite. The key is systematic categorisation: ISRO handles space, DRDO handles defence R&D, and each has signature projects. For SSC GD, you do not need to memorise every payload parameter—just the mission name, year, objective and result.
