इसरो ने 'शुक्रयान-1' मिशन के लिए पेलोड का सफल परीक्षण किया
भारतीय अंतरिक्ष अनुसंधान संगठन (ISRO) ने अपने आगामी शुक्र मिशन 'शुक्रयान-1' के लिए महत्वपूर्ण वैज्ञानिक उपकरणों का परीक्षण पूरा किया।
2-Minute Summary (TL;DR)
- ISRO successfully completed thermal-vacuum testing for the primary payload of its Venus mission, Shukrayaan-1.
- Shukrayaan-1 is India's first dedicated mission to explore Venus, planned for launch between late 2026 and early 2027.
- The mission aims to study Venus's atmosphere and surface geology, providing insights into planetary evolution.
- Venus experiences extreme surface temperatures exceeding 460°C due to a runaway greenhouse effect.
- The payload testing simulated the harsh space environment, including extreme temperatures and vacuum.
- Successful payload testing is a critical step ensuring the mission's readiness and instrument functionality.
- This mission will enhance India's standing in interplanetary exploration, following successes like Mangalyaan.
- Key scientific objectives include analyzing atmospheric composition and mapping surface features.

Practice Questions
Q1. What is the name of India's upcoming dedicated mission to Venus?
- Mangalyaan-2
- Chandrayaan-4
- Shukrayaan-1
- Aditya-L1
Explanation: Shukrayaan-1 is the designated name for ISRO's first dedicated mission to Venus. Mangalyaan was the Mars Orbiter Mission, Chandrayaan missions are for the Moon, and Aditya-L1 is for the Sun.
Q2. Which critical test was recently completed for the Shukrayaan-1 mission's primary payload?
- Vibration Test
- Electromagnetic Compatibility Test
- Thermal-Vacuum Test
- Acoustic Test
Explanation: The thermal-vacuum test is crucial for ensuring that the scientific instruments can withstand the extreme temperature fluctuations and vacuum conditions of space, particularly in the harsh environment of Venus.
Q3. What is the primary scientific objective of the Shukrayaan-1 mission?
- To study the Sun's corona
- To search for life on Mars
- To analyze the atmosphere and surface geology of Venus
- To map the lunar surface in high resolution
Explanation: Shukrayaan-1 is designed to conduct in-depth studies of Venus's atmosphere, including its chemical composition and dynamics, as well as to map its surface features and understand its geological history.
Q4. Which of the following best describes the typical surface temperature of Venus?
- Around 150 degrees Celsius
- Below freezing point of water
- Approximately 460 degrees Celsius
- Varies significantly between day and night, averaging 50 degrees Celsius
Explanation: Venus has an extreme greenhouse effect due to its dense carbon dioxide atmosphere, leading to surface temperatures that soar above 460 degrees Celsius, making it hotter than Mercury.
Q5. When is the planned launch window for the Shukrayaan-1 mission?
- Mid-2025
- Late 2026 or early 2027
- 2028
- Early 2026
Explanation: ISRO has targeted the end of 2026 or the beginning of 2027 as the optimal launch window for the Shukrayaan-1 mission, considering orbital mechanics for the journey to Venus.
How to Prepare Science & Technology for Government Exams — इसरो ने 'शुक्रयान-1' मिशन के लिए पेलोड का सफल परी…
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.
