Practice Questions
Q1. What is the name of ISRO's first interplanetary mission to Venus, launched on May 22, 2026?
- Mangalyaan-2
- Chandrayaan-4
- Shukrayaan-1
- Aditya-L1
Explanation: ISRO's first mission to Venus is named Shukrayaan-1. Mangalyaan was the Mars Orbiter Mission, Chandrayaan refers to lunar missions, and Aditya-L1 is a solar observation mission.
Q2. Which launch vehicle was used by ISRO for the Shukrayaan-1 mission?
- Polar Satellite Launch Vehicle (PSLV)
- Small Satellite Launch Vehicle (SSLV)
- Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III)
- Sounding Rocket
Explanation: The Shukrayaan-1 mission was launched using ISRO's powerful Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III), also known as LVM3. This vehicle is designed for heavier payloads and interplanetary missions.
Q3. Which instrument on board Shukrayaan-1 is crucial for mapping Venus's surface through its thick cloud cover?
- Infrared Spectrometer
- Magnetometer
- Synthetic Aperture Radar (SAR)
- Atmospheric Mass Spectrometer
Explanation: The Synthetic Aperture Radar (SAR) is crucial for mapping Venus's surface. Its ability to penetrate the planet's thick sulfuric acid clouds allows for high-resolution topographic imaging, revealing geological features otherwise obscured.
Q4. Which of the following is a primary characteristic of Venus's atmosphere?
- Composed mainly of nitrogen and oxygen
- Thin and cold, similar to Mars
- Dense, primarily carbon dioxide with sulfuric acid clouds
- Rich in methane and ammonia
Explanation: Venus has an extremely dense atmosphere composed primarily of carbon dioxide, with thick clouds of sulfuric acid. This composition leads to a runaway greenhouse effect and extremely high surface temperatures.
Q5. India's first successful interplanetary mission was to which planet?
- Venus
- Mars
- Jupiter
- Mercury
Explanation: India's first successful interplanetary mission was the Mars Orbiter Mission (MOM), also known as Mangalyaan, launched in 2013. Shukrayaan-1 is India's first mission to Venus.
