Practice Questions
Q1. What is the primary objective of ISRO's Shukrayaan-1 mission?
- To land a rover on Venus's surface
- To study Venus's thick atmosphere and surface composition
- To search for signs of past life on Venus's moons
- To deploy a satellite to study solar flares from Venus's orbit
Explanation: Shukrayaan-1 is an orbiter mission designed to conduct comprehensive studies of Venus's atmosphere and surface characteristics, aiming to understand its extreme climate and geological evolution.
Q2. Which of the following instruments is planned to be part of the Shukrayaan-1 payload for high-resolution mapping of Venus's surface?
- Infrared Spectrometer
- Gamma Ray Burst Detector
- Synthetic Aperture Radar (SAR)
- Magnetometer
Explanation: The Synthetic Aperture Radar (SAR) is a key instrument selected for Shukrayaan-1. Its purpose is to penetrate Venus's dense cloud cover and provide high-resolution maps of the planet's surface.
Q3. Which countries are collaborating with ISRO on the Shukrayaan-1 mission by providing scientific instruments?
- USA, Japan, Germany
- Sweden, France, Russia
- UK, Canada, Brazil
- China, South Korea, Italy
Explanation: ISRO's Shukrayaan-1 mission involves international cooperation, with scientific instruments being contributed by space agencies and research institutions from Sweden, France, and Russia.
Q4. Why is Venus often referred to as Earth's 'sister planet' despite its extreme conditions?
- It has a similar atmospheric composition to Earth.
- It is the only other planet in the solar system with liquid water.
- It is similar in size, mass, and density to Earth.
- It is the closest planet to Earth in terms of orbital distance.
Explanation: Venus is called Earth's 'sister planet' primarily because of its comparable size, mass, and density. However, its atmospheric and surface conditions are drastically different due to a runaway greenhouse effect.
Q5. What significant scientific insight can be gained from studying Venus's runaway greenhouse effect in the context of Earth?
- It proves that life can exist in extremely hot environments.
- It helps understand the potential impacts of climate change on Earth.
- It demonstrates the possibility of terraforming Venus into an Earth-like planet.
- It confirms that Venus once had oceans similar to Earth's ancient oceans.
Explanation: Studying Venus's extreme greenhouse effect, which led to its current uninhabitable state, provides crucial data and models that can help scientists better understand and predict the consequences of climate change on Earth.
How to Prepare Science & Technology for Government Exams — इसरो का शुक्रयान-1 मिशन: शुक्र के वायुमंडल के अध्…
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.
