Which of the following did Chandrayaan 3 NOT carry?
- A.A propulsion module
- B.A lander
- C.A rover
- D.A fresh lunar orbiter
Correct answer
Explanation
The correct answer is D, a fresh lunar orbiter. Chandrayaan 3 was deliberately built without one, because the orbiter of Chandrayaan 2 was still healthy in lunar orbit and could relay the lander's signals to the Earth. Leaving out a new orbiter saved weight and cost and let the mission concentrate on the landing that had failed in 2019.
Option A is wrong because the mission did carry a propulsion module, which took the lander to lunar orbit and then remained there with a single instrument observing the Earth. Option B is wrong because the lander Vikram was the heart of the mission and made the soft landing on 23 August 2023. Option C is wrong because the six wheeled rover Pragyan rolled out of the lander and carried two spectrometers that confirmed sulphur and several metals in the lunar soil.

- B.GSLV Mark Three
- C.SLV 3
- D.LVM3 M4
Show answer
The Polar Satellite Launch Vehicle in its extended configuration carried Chandrayaan 1 on 22 October 2008. The same family of rockets, in the C25 flight, later carried the Mars Orbiter Mission in 2013, which shows how much the Indian space programme achieved with a medium lift vehicle.

- A.Moon Impact Probe
- B.Moon Mineralogy Mapper
- C.Orbiter High Resolution Camera
- D.Lyman Alpha Photometer
Show answer
This imaging spectrometer, supplied by the United States space agency and flown on the Indian orbiter, measured how sunlight reflected from the lunar surface and found the absorption signature of water molecules and hydroxyl, especially towards the poles.
