ISRO का 'आदित्य-L1' मिशन विस्तार
भारतीय अंतरिक्ष अनुसंधान संगठन (ISRO) ने सौर मिशन 'आदित्य-L1' के परिचालन जीवन को बढ़ाने और नए डेटा संग्रह के लिए मिशन विस्तार की घोषणा की है।
2-Minute Summary (TL;DR)
- ISRO's Aditya-L1 solar mission has been extended by two years, increasing its total operational period to approximately seven years.
- Aditya-L1 is India's first dedicated solar observatory, launched on September 2, 2023.
- The spacecraft is positioned at the Sun-Earth Lagrange Point 1 (L1), about 1.5 million km from Earth, for continuous solar observation.
- The mission's primary objectives include studying the Sun's photosphere, chromosphere, and corona.
- Key instruments like VELC and SUIT are functioning optimally and providing valuable data on solar flares and CMEs.
- The extended mission aims to enhance understanding of space weather and its impact on Earth's systems.
- The L1 point offers an unobstructed view of the Sun, crucial for uninterrupted data collection.
- The mission's success highlights ISRO's growing capabilities in interplanetary space missions.
- Data from Aditya-L1 contributes to global research in solar physics and space weather prediction.
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. What is the primary reason for extending the operational life of ISRO's Aditya-L1 mission?
- To test new communication technologies
- The spacecraft exceeded performance expectations and requires more data collection time
- To observe a specific rare solar event predicted for the next two years
- To accommodate a delay in the launch of a subsequent ISRO mission
Explanation: The mission's exceptional performance and the wealth of scientific data it continues to gather have prompted ISRO to extend its mission by an additional two years. This decision underscores the success of the spacecraft and its instruments.
Q2. Aditya-L1 is strategically positioned at which location to conduct its solar observations?
- Geostationary Orbit
- Low Earth Orbit
- Sun-Earth Lagrange Point 1 (L1)
- Lunar Orbit
Explanation: Aditya-L1 is positioned at the Sun-Earth Lagrange Point 1 (L1), approximately 1.5 million kilometers from Earth. This location provides an unobstructed view of the Sun, free from the constraints of Earth's atmosphere and eclipses.
Q3. Which of the following is NOT a primary objective of the Aditya-L1 mission?
- Studying the Sun's photosphere
- Observing Coronal Mass Ejections (CMEs)
- Analyzing the Earth's magnetosphere
- Investigating the Sun's corona
Explanation: The primary objectives of Aditya-L1 are to study the Sun's photosphere, chromosphere, and corona, and to observe phenomena like solar flares and CMEs. Analyzing Earth's magnetosphere is not a primary objective of this solar mission.
Q4. What is the approximate total operational duration of the Aditya-L1 mission after its extension?
- 5 years
- 7 years
- 10 years
- 3 years
Explanation: The mission was originally designed for approximately 5 years. With the recent extension of two additional years, the total operational period of the Aditya-L1 mission will be approximately 7 years.
Q5. The data collected by Aditya-L1 is crucial for predicting and mitigating the effects of:
- Asteroid impacts
- Lunar eclipses
- Space weather events
- Geomagnetic storms on Venus
Explanation: Aditya-L1's continuous monitoring of solar activities like solar flares and CMEs provides vital data for predicting and mitigating the effects of space weather events, which can impact satellites, communication systems, and power grids on Earth.
How to Prepare Science & Technology for Government Exams — ISRO का 'आदित्य-L1' मिशन विस्तार
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.
