Practice Questions
Q1. What is the primary scientific objective of ISRO's Shukrayaan-1 mission?
- To search for signs of life on Mars
- To study the atmosphere and surface geology of Venus
- To explore the rings of Saturn
- To land a rover on the Moon's south pole
Explanation: Shukrayaan-1 is India's dedicated mission to Venus, aiming to study its atmospheric composition, dynamics, and surface features to understand its evolution and potential past habitability.
Q2. In which year was the final selection of scientific payloads for Shukrayaan-1 announced by ISRO?
- 2024
- 2025
- 2026
- 2027
Explanation: ISRO announced the final selection of scientific payloads for the Shukrayaan-1 mission in the first week of May 2026, marking a significant milestone for the project.
Q3. Which phenomenon is primarily responsible for Venus's extremely high surface temperatures?
- Proximity to the Sun
- Volcanic activity
- Runaway greenhouse effect
- Thin atmosphere
Explanation: Venus experiences a runaway greenhouse effect due to its dense atmosphere, primarily composed of carbon dioxide, which traps heat and leads to surface temperatures averaging around 462 degrees Celsius.
Q4. What is the expected launch year for ISRO's Shukrayaan-1 mission?
- 2028
- 2029
- 2030
- 2031
Explanation: The Shukrayaan-1 mission to Venus is currently targeted for launch in the year 2031, following the finalization of its scientific payload.
Q5. Shukrayaan-1 is significant for India primarily because it is:
- India's first mission to Jupiter
- India's first dedicated mission to Venus
- India's third mission to Mars
- India's first attempt at manned spaceflight
Explanation: Shukrayaan-1 represents a major step for ISRO as it will be India's first dedicated interplanetary mission specifically focused on exploring Venus, showcasing the nation's growing capabilities in deep space exploration.
How to Prepare Science & Technology for Government Exams — इसरो का 'शुक्रयान-1' मिशन: वीनस के रहस्यों को सुल…
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.
