Practice Questions
Q1. Which launch vehicle was used by ISRO for the Shukrayaan-1 Venus Orbiter Mission?
- PSLV-XL
- GSLV Mk III
- LVM2
- SSLV
Explanation: The GSLV Mk III, also known as LVM3, is ISRO's heaviest launch vehicle and was chosen for the Shukrayaan-1 mission due to its capability to carry heavier payloads into higher orbits, essential for an interplanetary mission to Venus.
Q2. What is the primary objective of ISRO's Shukrayaan-1 mission?
- To study the Martian atmosphere
- To explore Jupiter's moons
- To analyze Venus's atmosphere, surface, and solar wind interaction
- To deploy a rover on the lunar surface
Explanation: Shukrayaan-1 is India's first dedicated mission to Venus. Its core objectives are to conduct comprehensive studies of the Venusian atmosphere, investigate its surface geology, and understand the interaction between the solar wind and the planet's ionosphere.
Q3. From which launch site was the Shukrayaan-1 mission initiated?
- Vikram Sarabhai Space Centre
- Thumba Equatorial Rocket Launching Station
- Satish Dhawan Space Centre
- Abdul Kalam Island
Explanation: The Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh, is India's primary spaceport. All major satellite and rocket launches by ISRO, including interplanetary missions like Shukrayaan-1, originate from this facility.
Q4. Which of the following instruments is mentioned as being carried by the Shukrayaan-1 orbiter for surface mapping?
- Alpha Particle X-ray Spectrometer
- Synthetic Aperture Radar
- Magnetometer
- Seismometer
Explanation: The Shukrayaan-1 orbiter is equipped with a Synthetic Aperture Radar (SAR). This instrument is crucial for penetrating Venus's thick clouds to map its surface features and study its geology, as optical cameras are ineffective due to the dense atmosphere.
Q5. Shukrayaan-1 represents India's third major interplanetary mission after which two celestial bodies?
- Jupiter and Saturn
- Mercury and Uranus
- Moon and Mars
- Asteroids and Comets
Explanation: Prior to Shukrayaan-1, ISRO successfully launched missions to the Moon (Chandrayaan series) and Mars (Mangalyaan/Mars Orbiter Mission). Shukrayaan-1 thus marks India's third significant foray into interplanetary exploration.
How to Prepare Science & Technology for Government Exams — ISRO Successfully Launches Shukrayaan-1 Venus Orb…
For Railway exams, make flashcards for every major ISRO launch — name, payload, purpose, date. These repeat frequently.
