Practice Questions
Q1. What is the name of ISRO's first dedicated mission to Venus?
- Mangalyaan-2
- Chandrayaan-3
- Shukrayaan-1
- Aditya-L1
Explanation: Shukrayaan-1 is the designated name for India's inaugural mission to explore Venus. Mangalyaan-2 is a proposed Mars mission, Chandrayaan-3 was a lunar mission, and Aditya-L1 is a solar observation mission.
Q2. Which ISRO facility is responsible for the final integration and testing of the Shukrayaan-1 spacecraft?
- Satish Dhawan Space Centre (SDSC)
- Vikram Sarabhai Space Centre (VSSC)
- U R Rao Satellite Centre (URSC)
- Liquid Propulsion Systems Centre (LPSC)
Explanation: The U R Rao Satellite Centre (URSC) in Bengaluru is ISRO's lead centre for the design, development, and realization of satellites, including their final integration and testing. SDSC is primarily for launch operations, VSSC for launch vehicle development, and LPSC for liquid propulsion systems.
Q3. What is one of the key scientific instruments Shukrayaan-1 is expected to carry to study the Venusian surface?
- X-ray Spectrometer
- Synthetic Aperture Radar (SAR)
- Alpha Particle X-ray Spectrometer (APXS)
- Magnetometer
Explanation: A Synthetic Aperture Radar (SAR) is crucial for Shukrayaan-1 as it can penetrate Venus's thick, opaque clouds to map its surface features, including potential volcanic activity. X-ray spectrometers and APXS are typically used for elemental composition analysis on surfaces, and magnetometers measure magnetic fields.
Q4. The primary objective of Shukrayaan-1 is to study Venus. Why is Venus often referred to as Earth's "twin"?
- Similar atmospheric composition
- Similar orbital period
- Similar size and mass
- Presence of liquid water
Explanation: Venus is often called Earth's "twin" due to its comparable size, mass, and bulk composition. However, its atmospheric conditions and surface environment are vastly different and extremely hostile, making it a key subject for comparative planetary science.
Q5. Which of the following rockets is ISRO planning to use for the launch of Shukrayaan-1?
- PSLV
- GSLV Mk III (LVM3)
- SSLV
- RLV-TD
Explanation: For a deep space mission like Shukrayaan-1, a more powerful launch vehicle is required. ISRO plans to use either the GSLV Mk II or the LVM3 (formerly GSLV Mk III), which has the necessary payload capacity to send the spacecraft to Venus. PSLV is for smaller payloads and lower orbits, SSLV is for micro-satellites, and RLV-TD is a technology demonstrator.
How to Prepare Science & Technology for Government Exams — ISRO's Shukrayaan-1: India's Venus Mission Enters…
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.
