Practice Questions
Q1. Which Indian space mission is dedicated to the study of Venus?
- Mangalyaan-2
- Chandrayaan-3
- Shukrayaan-1
- Aditya-L1
Explanation: Shukrayaan-1 is ISRO's planned orbiter mission to Venus, making it India's first dedicated mission to study the planet. Mangalyaan-2 is a proposed Mars mission, Chandrayaan-3 was a lunar lander, and Aditya-L1 is a solar observation mission.
Q2. What is the primary objective of the Shukrayaan-1 mission?
- To establish a human colony on Mars
- To study the Sun's corona and solar winds
- To explore the surface and atmosphere of Venus
- To search for water ice at the lunar poles
Explanation: The Shukrayaan-1 mission is specifically designed to conduct comprehensive studies of Venus, focusing on its atmospheric composition, surface features, and interaction with the solar wind. Other options pertain to different missions or objectives.
Q3. Which of the following instruments is a key payload on Shukrayaan-1 for surface mapping?
- X-ray Spectrometer
- Synthetic Aperture Radar (SAR)
- Magnetometer
- Infrared Spectrometer
Explanation: A high-resolution Synthetic Aperture Radar (SAR) is a crucial instrument on Shukrayaan-1, designed to penetrate Venus's thick clouds and map its surface features. While other instruments might be present, SAR is specifically highlighted for surface mapping.
Q4. Which ISRO mission successfully explored Mars prior to the planning of Shukrayaan-1?
- Chandrayaan-1
- Mangalyaan (Mars Orbiter Mission)
- Gaganyaan
- IRNSS
Explanation: The Mars Orbiter Mission (MOM), also known as Mangalyaan, was India's first successful interplanetary mission to Mars, launched in 2013. Chandrayaan-1 was a lunar mission, Gaganyaan is a human spaceflight program, and IRNSS is a navigation satellite system.
Q5. Venus is often referred to as Earth's 'twin' primarily due to which characteristic?
- Similar atmospheric composition
- Presence of liquid water on its surface
- Comparable size and mass
- Similar magnetic field strength
Explanation: Venus is called Earth's 'twin' because it has a similar size and mass to Earth. However, its atmospheric composition, surface conditions, and lack of liquid water are vastly different and much harsher than Earth's.
