The Pragyan rover installed in Chandrayaan-2 mission had how many wheels?

  1. A.2
  2. B.3
  3. C.4
  4. D.6

Correct answer

D. 6

Explanation

The correct answer is D, 6. Pragyan was a six-wheeled rover carried inside the Vikram lander.

Chandrayaan-2 was launched on 22 July 2019 by the GSLV Mk III with an orbiter, the Vikram lander and the Pragyan rover. Pragyan, Sanskrit for 'wisdom', was a small solar-powered rover meant to move on six wheels and study the lunar soil. Vikram crash-landed in September 2019, so the rover never rolled out, while the orbiter kept working. Chandrayaan-3 then landed a similar six-wheeled Pragyan near the lunar south pole on 23 August 2023.

A is wrong because a two-wheeled rover would not be stable on the uneven lunar surface. B is wrong because Pragyan did not use a three-wheeled design. C is wrong because Pragyan had six wheels, not four, which spread its weight and help it cross rough ground.

Exam tip: Pragyan: six wheels; Chandrayaan-2 (2019) lander Vikram crashed; Chandrayaan-3 landed on 23 August 2023, now National Space Day.
