ISRO का शुक्रयान-1 मिशन: शुक्र ग्रह के रहस्यों को सुलझाने की तैयारी
भारतीय अंतरिक्ष अनुसंधान संगठन (ISRO) ने अपने आगामी शुक्र मिशन 'शुक्रयान-1' के लिए पेलोड चयन प्रक्रिया पूरी कर ली है, जिसे 2026 के अंत तक लॉन्च किया जाना है।
2-Minute Summary (TL;DR)
- Shukrayaan-1 is ISRO's upcoming orbiter mission to Venus, with a targeted launch by the end of 2026.
- The mission aims to study Venus's atmosphere, surface, and geological processes.
- Key scientific objectives include understanding Venus's extreme greenhouse effect and atmospheric composition.
- The mission will carry advanced payloads, including a high-resolution radar and atmospheric analysis instruments.
- Venus is often called Earth's 'twin sister' but has extreme surface temperatures (around 462°C) and a dense CO2 atmosphere.
- Shukrayaan-1 builds on ISRO's successful interplanetary missions like Mangalyaan (Mars Orbiter Mission).
- The mission signifies India's growing capabilities in complex space exploration and planetary science.
- Insights from Shukrayaan-1 could help refine climate models for Earth and understand planetary evolution.

Practice Questions
Q1. What is the primary objective of ISRO's Shukrayaan-1 mission?
- To land a rover on Venus's surface
- To study the atmosphere and surface of Venus
- To search for signs of life on Venus's moons
- To deploy a satellite into Venus's orbit for communication
Explanation: Shukrayaan-1 is an orbiter mission designed to study the complex atmosphere and surface of Venus, gathering data on its composition, dynamics, and geological features.
Q2. Which planet is ISRO's Shukrayaan-1 mission targeted to explore?
- Mars
- Jupiter
- Venus
- Saturn
Explanation: Shukrayaan-1 is specifically designed to explore Venus, Earth's closest planetary neighbor, which is often referred to as its 'twin sister' due to similarities in size and mass.
Q3. Approximately when is the Shukrayaan-1 mission expected to be launched?
- Mid-2025
- End of 2026
- Early 2027
- Late 2024
Explanation: ISRO has indicated that the Shukrayaan-1 mission is targeted for launch in the latter half of 2026, following the successful completion of its payload selection process.
Q4. What is a significant environmental characteristic of Venus that makes its study challenging and important?
- Extremely low surface temperatures and thin atmosphere
- Presence of liquid water oceans on the surface
- A runaway greenhouse effect leading to extremely high surface temperatures
- Intense magnetic field protecting it from solar radiation
Explanation: Venus experiences a runaway greenhouse effect due to its dense carbon dioxide atmosphere, resulting in surface temperatures averaging around 462 degrees Celsius (864 degrees Fahrenheit), making it a crucial case study for climate science.
Q5. Which previous ISRO mission's success is often cited as a precursor and confidence builder for missions like Shukrayaan-1?
- Chandrayaan-2
- NavIC
- Mangalyaan (Mars Orbiter Mission)
- RISAT-1
Explanation: The cost-effective and highly successful Mars Orbiter Mission (Mangalyaan) demonstrated ISRO's capabilities in interplanetary exploration and provided valuable experience for undertaking future complex missions like Shukrayaan-1.
How to Prepare Science & Technology for Government Exams — ISRO का शुक्रयान-1 मिशन: शुक्र ग्रह के रहस्यों को…
For Railway exams, make flashcards for every major ISRO launch — name, payload, purpose, date. These repeat frequently.
For SSC, focus on defence acquisitions and their strategic significance rather than technical specs.
For UPSC, connect every scientific development to policy — climate targets, digital India, health policy.
