Overview
Science & Technology is a pivotal segment in PSU entrance exams, focusing on recent national advancements and foundational concepts in space, defense, and digital infrastructure. It tests an aspirant's awareness of India's scientific progress and the ability to link theoretical knowledge with current global technological trends.
Space Missions & ISRO
This section covers India's strategic space programs, launch vehicle capabilities, and landmark international collaborations. Focus on the distinction between Polar Satellite Launch Vehicles (PSLV) and Geosynchronous Satellite Launch Vehicles (GSLV) alongside flagship missions.
- Chandrayaan-3: First mission to land on the Lunar South Pole
- Aditya-L1: India's maiden solar observatory mission
- PSLV: Often called the Workhorse of ISRO
- Mangalyaan (MOM): India's first Mars orbiter mission
- Gaganyaan: ISRO's human spaceflight program
Nuclear Energy & Defence Technology
Emphasis is placed on India's nuclear power infrastructure and the 'Make in India' initiative in defense systems. Candidates should recognize the difference between tactical missiles and strategic defense assets.
- Agni-V: Intercontinental Ballistic Missile (ICBM) with 5000km+ range
- BrahMos: World's fastest supersonic cruise missile
- NPCIL: Operates nuclear power plants in India
- INS Vikrant: India's first indigenously built aircraft carrier
- Akash: Surface-to-air missile system
Biotechnology & Medical Discoveries
This subtopic explores recent developments in vaccine manufacturing, gene editing, and medical technology advancements in India. Key focus areas include mRNA technology and public health initiatives.
- COVAXIN: India's first indigenous COVID-19 vaccine
- CRISPR-Cas9: Modern gene-editing technology
- Stem Cell Research: Therapeutic applications in regenerative medicine
- National Biotechnology Development Strategy focus areas
AI & Digital India
Digital transformation initiatives are evaluated through the lens of governance, cybersecurity, and emerging computational technologies. Stay updated on government frameworks for AI deployment and digital financial inclusion.
- BHIM/UPI: Unified Payments Interface infrastructure
- National AI Portal (INDIAai): Governance of AI ethics
- 5G Technology: Frequency bands and industrial applications
- Aadhaar: World's largest biometric ID system architecture
Exam Tip
Focus heavily on 'firsts'—the first indigenous missile, first lunar landing, or first orbital mission—as these are the most frequently asked targets in PSU exams.
Common Mistakes
- Confusing the roles of PSLV and GSLV launch vehicles in exam questions.
- Failing to distinguish between different generations of missile systems (e.g., Agni series vs. Prithvi series).
- Relying on outdated launch dates instead of verifying the current year's mission objectives.
