Practice Questions
Q1. Which launch vehicle was used by ISRO for the Chandrayaan-4 mission?
- Polar Satellite Launch Vehicle (PSLV)
- Small Satellite Launch Vehicle (SSLV)
- Launch Vehicle Mark-3 (LVM3)
- Geosynchronous Satellite Launch Vehicle (GSLV)
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 vehicle is capable of carrying heavy payloads into various orbits and has been used for previous lunar missions and Gaganyaan tests.
