Practice Questions
Q1. Which launch vehicle was used by ISRO for the Chandrayaan-4 mission?
- PSLV-XL
- GSLV Mk-II
- LVM3
- SSLV
Explanation: The Chandrayaan-4 mission was launched using ISRO's heaviest operational rocket, the Launch Vehicle Mark-3 (LVM3), previously known as GSLV Mk-III. This powerful rocket is capable of carrying heavy payloads to geostationary transfer orbits and beyond.
Q2. What is the primary objective of the Chandrayaan-4 mission?
- To deploy a human crew on the Moon
- To establish a permanent lunar base
- To return lunar soil and rock samples to Earth
- To orbit Jupiter and study its moons
Explanation: The Chandrayaan-4 mission's primary objective is to collect lunar soil and rock samples from the Moon's South Pole and return them to Earth for scientific analysis. This is a highly complex mission profile, marking a significant advancement in India's space capabilities.
Q3. Which region of the Moon is the Chandrayaan-4 mission specifically targeting for its landing and sample collection?
- Sea of Tranquility
- Oceanus Procellarum
- Lunar Equator
- Lunar South Pole
Explanation: Chandrayaan-4 is specifically targeting the Moon's South Pole region. This area is of great scientific interest due to the potential presence of significant quantities of water ice in its permanently shadowed regions, which could be vital for future lunar missions.
