Practice Questions
Q1. What is the primary objective of ISRO's Shukrayaan-1 mission?
- To search for signs of life on Mars
- To study the atmosphere and surface of Venus
- To deploy a telescope in orbit around Jupiter
- To land a rover on the Moon's south pole
Explanation: Shukrayaan-1 is ISRO's dedicated mission to Venus, focusing on analyzing its atmospheric composition and surface characteristics. The mission aims to understand the planet's extreme climate and geological history.
Q2. When is the Shukrayaan-1 mission expected to be launched?
- Late 2025
- Early 2026
- Late 2026 or early 2027
- Mid 2028
Explanation: ISRO has announced that the launch window for Shukrayaan-1 is anticipated to be between the end of 2026 and the beginning of 2027. This timeline follows the completion of critical payload selection.
Q3. Which of the following is a key instrument planned for the Shukrayaan-1 mission?
- A powerful X-ray telescope
- A high-resolution radar
- A deep-sea submersible
- A seismic activity sensor
Explanation: A high-resolution radar is among the key instruments selected for Shukrayaan-1. This radar is crucial for penetrating Venus's thick cloud cover to map its surface features.
Q4. Why is Venus often referred to as 'Earth's twin'?
- It has a similar atmosphere to Earth
- It has liquid water on its surface
- It shares similarities in size, mass, and density with Earth
- It is the only other planet known to support life
Explanation: Venus is called 'Earth's twin' because it is very similar to Earth in terms of its size, mass, and density. However, its current environment is drastically different due to a runaway greenhouse effect.
Q5. What potential benefit can studying Venus's climate offer for Earth?
- It can help predict earthquakes
- It can provide insights into managing Earth's runaway greenhouse effect
- It can reveal new sources of fossil fuels
- It can lead to the discovery of extraterrestrial life
Explanation: By studying the extreme greenhouse effect on Venus, scientists can gain a better understanding of atmospheric dynamics and the long-term impacts of greenhouse gases. This knowledge can help refine climate models for Earth and inform strategies to combat climate change.
How to Prepare Science & Technology for Government Exams — इसरो का शुक्रयान-1 मिशन: वीनस की कक्षा में प्रवेश…
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.
