Which of the Statements given above is/are incorrect?
[A] 1 only
[B] 2 only
[C] Both 1 and 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: B [2 only ]
Notes:- Unlike the Chandrayaan-3 mission which carried the 25-kilogram rover ‘Prayagyaan’, the Chandrayaan-5 mission would carry a 250 kg rover to study the moon’s surface. Correct: Unlike the Chandrayaan-3 mission which carried the 25-kilogram rover ‘Praya gyaan’, the Chandrayaan-5 mission would carry a 250 kg rover to study the moon’s surface.
- ISRO successfully launched the Chandrayaan-2 mission with the Lander Vikram successfully ‘soft-landing’ on the South pole of the Moon in 2019. Incorrect: The Chandrayaan-2 mission (2019) was 98% successful, with only a minor setback in the final stages. However, its high-resolution camera continues to capture and send images. Chandrayaan-3 is a follow-up mission aimed at demonstrating safe lunar landing and roving capabilities.
