🚀 ISRO 2025 Explosion: Gaganyaan Launch Prep, Aditya-L1 Decodes Solar Storms, Shukrayaan Venus Strategy Ready
The Indian Space Research Organisation (ISRO) is no longer just a rocket-launching agency; it has become a strategic power in global science, human spaceflight, and planetary exploration. The three major missions ISRO is accelerating in 2025—Gaganyaan, Aditya-L1, and Shukrayaan—have become high-scoring potential topics for all upcoming competitive exams.
🧑🚀 1. Gaganyaan: India's First Manned Space Mission
🔍 Mission Objective: The aim of Gaganyaan is to include India in the elite list of countries with Human Spaceflight capability. ISRO will send Indian astronauts to Low Earth Orbit (LEO) and bring them back safely to Earth.
📍 Key Points (Exam-Important):
• India's first Crewed Space Mission.
• Orbit: Low Earth Orbit (LEO) at ~400 km.
• Launch Vehicle: LVM-3 (formerly GSLV Mk-III).
• Astronaut Training: Conducted in Russia.
• Indian Astronauts are called: Vyomnauts.
• Features: Crew Escape System and Parachute Assisted Landing.
• Pre-mission tests: Uncrewed flights (G1, G2 missions) are underway.
• India's first Crewed Space Mission.
• Orbit: Low Earth Orbit (LEO) at ~400 km.
• Launch Vehicle: LVM-3 (formerly GSLV Mk-III).
• Astronaut Training: Conducted in Russia.
• Indian Astronauts are called: Vyomnauts.
• Features: Crew Escape System and Parachute Assisted Landing.
• Pre-mission tests: Uncrewed flights (G1, G2 missions) are underway.
Recent Achievements: ISRO successfully completed parachute system and safe re-entry tests for the Crew Module. This is a critical milestone likely to appear in UPSC, State PSC, and SSC exams.
☀️ 2. Aditya-L1: India's First Solar Observatory
🔍 Mission Objective: To study the Sun's Corona (outer layer), Solar Winds, Solar Flares, and Coronal Mass Ejections (CME).
📍 Key Points (Exam-Important):
• India's first dedicated Solar Observatory.
• Location: Lagrange Point-1 (L1), approx. 1.5 million km from Earth.
• L1 Feature: Provides a continuous view of the Sun without eclipses.
• Payloads: 7 major instruments, including VELC and SUIT.
• Launch Vehicle: PSLV-C57.
• India's first dedicated Solar Observatory.
• Location: Lagrange Point-1 (L1), approx. 1.5 million km from Earth.
• L1 Feature: Provides a continuous view of the Sun without eclipses.
• Payloads: 7 major instruments, including VELC and SUIT.
• Launch Vehicle: PSLV-C57.
Scientific Impact: Aditya-L1 is contributing to global research on Solar Storms, which helps in predicting space weather and protecting communication satellites.
♀️ 3. Shukrayaan: India's Vision for Venus
🔍 Mission Objective: A Venus exploration mission to study the planet's thick atmosphere, sulfuric acid clouds, and extreme greenhouse effect.
📍 Key Points (Exam-Important):
• Mission Name: Shukrayaan-1.
• Target: Venus (The hottest planet).
• Focus: Atmosphere + Surface study.
• Challenges: Extreme surface temperatures (~470°C) and high atmospheric pressure.
• Mission Name: Shukrayaan-1.
• Target: Venus (The hottest planet).
• Focus: Atmosphere + Surface study.
• Challenges: Extreme surface temperatures (~470°C) and high atmospheric pressure.
