इसरो का शुक्रयान-1 मिशन: शुक्र ग्रह की ओर भारत का पहला कदम
भारतीय अंतरिक्ष अनुसंधान संगठन (ISRO) ने शुक्र ग्रह के वायुमंडल का अध्ययन करने के लिए 'शुक्रयान-1' मिशन की तैयारी पूरी कर ली है।
2-Minute Summary (TL;DR)
- Shukrayaan-1 is India's first dedicated mission to Venus, planned for launch by ISRO by the end of 2026.
- The mission aims to study Venus's atmosphere, surface composition, and volcanic activity.
- Venus is often called Earth's 'twin planet' due to similar size and mass, but has extreme conditions (surface temp ~460°C).
- The mission will involve an orbiter analyzing Venus's dense atmosphere, primarily carbon dioxide and sulfuric acid clouds.
- Shukrayaan-1 will investigate the runaway greenhouse effect and solar wind interaction with Venus's atmosphere.
- This mission expands India's interplanetary exploration beyond the Moon (Chandrayaan) and Mars (Mangalyaan).
- The mission's expected duration is at least 4 Earth years.
- Understanding Venus's climate evolution provides insights into Earth's climate future and planetary habitability.
How This Topic is Tested in Competitive Exams
| Exam | Frequency | Approx. Marks | What Gets Asked |
|---|---|---|---|
| UPSC / State PCS | Medium | 5–8 | UPSC tests Science & Technology through governance: space policy, biotech regulations, cyber security. |
| SSC (CGL / CHSL / MTS) | High | 4–8 | Basic science, space missions, ISRO launches, and defence technology are standard SSC GK topics. |
| Railway (RRB NTPC / Group D) | Very High | 6–10 | Science and Technology is one of the largest GK sections in Railway papers. |

Practice Questions
Q1. Which organization is responsible for the Shukrayaan-1 mission?
- NASA
- ESA
- ISRO
- JAXA
Explanation: Shukrayaan-1 is an ambitious interplanetary mission undertaken by the Indian Space Research Organisation (ISRO). ISRO is India's national space agency dedicated to space exploration and technological development.
Q2. What is the primary target planet for the Shukrayaan-1 mission?
- Mars
- Venus
- Jupiter
- Saturn
Explanation: Shukrayaan-1 is specifically designed as India's first dedicated mission to study the planet Venus. It aims to explore its atmosphere and surface characteristics.
Q3. Approximately when is the Shukrayaan-1 mission planned to be launched?
- Mid-2025
- End of 2026
- Early 2027
- Late 2028
Explanation: ISRO has announced its intention to launch the Shukrayaan-1 mission by the end of 2026. This timeframe allows for the finalization of all technological and scientific preparations.
Q4. Which of the following is a key scientific objective of the Shukrayaan-1 mission?
- To search for signs of past life on Mercury
- To study the rings of Saturn
- To analyze the composition of Venus's sulfuric acid clouds
- To measure the magnetic field of Jupiter
Explanation: A primary focus of Shukrayaan-1 is to analyze the dense atmosphere of Venus, particularly its characteristic sulfuric acid clouds. This study is crucial for understanding the planet's extreme climate.
Q5. Why is Venus often referred to as Earth's 'twin planet' despite its extreme conditions?
- It has a similar atmosphere and liquid water on its surface.
- It has the same rotational period as Earth.
- It shares similar size, mass, and density with Earth.
- It possesses a strong magnetic field like Earth.
Explanation: Venus is called Earth's 'twin' primarily due to its comparable size, mass, and density. However, its atmospheric composition and extreme surface temperatures make it vastly different and inhospitable compared to Earth.
How to Prepare Science & Technology for Government Exams — इसरो का शुक्रयान-1 मिशन: शुक्र ग्रह की ओर भारत का…
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.
