Which unique feature distinguishes the Chandrayaan-3 lander 'Vikram' from its predecessor in Chandrayaan-2?
Show answer & explanation
Correct answer: C
Explanation
Answer: It had enhanced navigation and hazard avoidance capabilities
Explanation:
Chandrayaan-3's lander, 'Vikram', was launched with several significant improvements compared to its predecessor, Chandrayaan-2. Learning from the failure of Chandrayaan-2, ISRO equipped Chandrayaan-3's lander with a 'Lander Hazard Detection and Avoidance Camera' (LHDAC) and advanced navigation sensors. These technologies assist the lander, during its descent, in identifying craters or boulders on the lunar surface and ensuring a safe landing at a secure location. Furthermore, its landing legs were strengthened to withstand the impact of a landing even at higher velocities, and its fuel capacity was also increased.
Additional Points:
LHDAC: This camera captures images of the terrain below during the landing process to help avoid any potential hazards.
Laser Doppler Velocimeter: This instrument was installed to accurately measure the lander's velocity.
Soft Landing: Chandrayaan-3 executed a successful 'soft landing' near the lunar South Pole on August 23, 2023.
Launch Vehicle: It was launched using the LVM3-M4 rocket.
