Explanation: The mission's core scientific goals are to analyze Venus's dense atmosphere, understand its complex atmospheric processes, and map its surface, including volcanic activity, using advanced instruments.
Q2. On which date did 'Shukrayaan-1' successfully achieve orbital insertion around Venus?
- October 20, 2025
- April 30, 2026
- July 15, 2025
- December 1, 2026
Explanation: The successful orbital insertion of the 'Shukrayaan-1' spacecraft around Venus was officially announced by ISRO on April 30, 2026, marking a significant milestone.
Q3. Which launch vehicle was used for ISRO's 'Shukrayaan-1' mission?
- PSLV-XL
- GSLV Mk II
- GSLV Mk III (LVM3)
- SSLV
Explanation: The 'Shukrayaan-1' mission was launched using ISRO's most powerful operational launch vehicle, the GSLV Mk III, which is now designated as the Launch Vehicle Mark-3 (LVM3).
Q4. What is a key scientific instrument onboard 'Shukrayaan-1' designed to penetrate Venus's thick cloud cover?
- Infrared Spectrometer
- Ultraviolet Imager
- Synthetic Aperture Radar (SAR)
- Magnetometer
Explanation: The Synthetic Aperture Radar (SAR) is a crucial instrument on 'Shukrayaan-1' that allows scientists to image the surface of Venus by penetrating its dense, opaque atmosphere.
Q5. The 'Shukrayaan-1' mission is significant because it places India among a group of nations that have successfully:
- Landed humans on Mars
- Sent probes to Jupiter's moons
- Explored Venus with an orbiter mission
- Established a lunar base
Explanation: By successfully orbiting Venus, ISRO's 'Shukrayaan-1' mission makes India one of the few space agencies globally to have sent a mission to study Venus, highlighting its advanced interplanetary exploration capabilities.
How to Prepare Science & Technology for Government Exams — ISRO का 'शुक्रयान-1' मिशन: वीनस की कक्षा में सफल…
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.
