Practice Questions
Q1. What is the name of ISRO's mission to Venus that successfully entered its orbit on January 20, 2026?
- Mangalyaan-2
- Chandrayaan-4
- Shukrayaan-1
- Aditya-L1
Explanation: Shukrayaan-1 is the designation for India's first orbiter mission to Venus, launched by ISRO. The mission successfully achieved Venus Orbit Insertion on January 20, 2026.
Q2. Which rocket was used by ISRO to launch the Shukrayaan-1 mission?
- PSLV-C50
- GSLV Mk III
- GSLV Mk II
- SSLV-D2
Explanation: The GSLV Mk II (Geosynchronous Satellite Launch Vehicle Mark II) rocket was utilized by ISRO for the launch of the Shukrayaan-1 mission, indicating its capability to carry heavier payloads for interplanetary journeys.
Q3. Which of the following is NOT a primary scientific objective of the Shukrayaan-1 mission?
- Studying the composition of Venus's atmosphere
- Searching for active volcanism on Venus's surface
- Analyzing the interaction of solar wind with Venus's ionosphere
- Detecting subsurface water reservoirs on Venus
Explanation: While Shukrayaan-1 is designed to study the Venusian surface and atmosphere extensively, the detection of subsurface water reservoirs is not a primary objective, given the extreme surface conditions and the mission's specific instrumentation focus.
Q4. Upon successful orbit insertion, India became which number space agency to successfully send a mission to Venus?
- Second
- Third
- Fourth
- Fifth
Explanation: With the successful Venus Orbit Insertion of Shukrayaan-1, India joins the ranks of the Soviet Union, the United States, and the European Space Agency as the fourth entity to achieve this milestone.
Q5. What are the key instruments aboard Shukrayaan-1 designed to study the Venusian surface, which is obscured by thick clouds?
- Infrared Spectrometer and Magnetometer
- High-Resolution Synthetic Aperture Radar (SAR) and Ground Penetrating Radar (GPR)
- Ultraviolet Imager and X-ray Spectrometer
- Gamma Ray Burst Detector and Cosmic Ray Detector
Explanation: Shukrayaan-1 is equipped with a High-Resolution Synthetic Aperture Radar (SAR) and Ground Penetrating Radar (GPR). These instruments are crucial for penetrating Venus's thick cloud cover to study its surface and subsurface characteristics.
How to Prepare Science & Technology for Government Exams — ISRO's Shukrayaan-1 Successfully Enters Venusian…
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.
