A. GSLV

B. LVSM

C. GSLV-Mk3

D. PSLV

Ans. C

Explanation: The chosen launcher for Chandrayaan-3 is GSLV-Mk3, which will position the integrated module in an Elliptic Parking Orbit (EPO) measuring approximately 170 x 36500 km in size.

5. The mission objectives of Chandrayaan-3

A. To demonstrate Rover roving on the moon and

B. To demonstrate a Safe and Soft Landing on Lunar Surface

C. To conduct in-situ scientific experiments.

D. All of the above

Ans. D

Explanation: ISRO has set three main objectives for the Chandrayaan-3 mission, which include:

1. Getting a lander safe and soft landing on the surface of the Moon.
2. Observing and demonstrating the rover’s loitering capabilities on the Moon
3. In-site scientific observation makes scientific experiments on the chemical and natural elements, soil, water, etc. available on the surface of the Moon to better understand and practice the composition of the Moon. Interplanetary refers to the development and demonstration of new technologies required for missions between two planets.

6. How much did the Chandrayaan 3 mission cost?

A. 1200 Crores

B. 960 Crores

C. 600 Crores

D. 540 Crores

Ans. C

Explanation: Chandrayaan 3 mission costs lesser than the Chandrayaan 2 mission which was more than 960 crores.

7. What is the total weight of Chandrayaan 3?

A. 4,100 kilograms

B. 3,900 kilograms

C. 2,190 kilograms

D. 5,200 kilograms

Ans. B

Explanation: The propulsion module, alone, weighs 2,148 kg, and the lander and the rover are both in the lander module, which weighs 1,752 kilograms.

8. What is that one thing in Chandrayaan 3 and not in Chandrayaan 2?

A. Laser Doppler Velocimeter (LDV)

B. Laser-based Interferometry

C. Ultrasonic Doppler methods

D. Molecular Tagging Velocimetry

Ans. A

Explanation: The lander for Chandrayaan-3 will have only four throttle-able engines, equipped with a Laser Doppler Velocimeter (LDV).

9. Which of the following is missing in Chandrayaan 3?

A. Rover

B. Lander

C. Orbiter

D. None of the above

Ans. C

Explanation: According to ISRO, Chandrayaan-2, was fitted with the lander Vikram, an orbiter and rover Pragyan, whereas Chandrayaan-3 will carry only a rover and a lander. Also, the orbiter that was launched with Chandrayaan-2 will still be in use.

10. What will be the design of the Propulsion Module?

A. Box-like structure with a solar panel on the side with a cylinder on top

B. Rectangular structure with solar panels on all sides

C. Cube with a sphere on top

D. None of the above

Ans. A

Explanation: The Propulsion Module is a box-like structure with a huge solar panel on one side and a massive cylinder on top. The cylinder, known as the Intermodule Adapter Cone, will serve as the lander’s mounting framework.

11. Who is the director of the Chandrayaan 3 mission?

A. Veeramuthuvel

B. M Vanitha

C.  Ritu Karidhal

D. K. Sivan

Ans. C

Explanation: Ritu Kharidhal is a prominent scientist at the Indian Space Research Organisation (ISRO). She will be leading the launch of Chandrayaan-3 this year.

12. Where will Chandrayaan 3 land on the moon?

A. Near the South Pole

B. Near the North Pole

C. In the equatorial region

D. None of the above

Ans. A 

Explanation: The objective of this mission is to explore the South Pole of the moon. This is because the south pole of the moon is rich in water ice, which is a valuable resource for future lunar exploration. The south pole is also less explored than the north pole, so there is a lot of scientific potential in landing there.

13. What are the challenges that ISRO will face in the Chandrayaan 3 mission?

A. The lunar surface is very harsh, and the lander and rover will need to be able to withstand extreme conditions.

B. The landing site is near the south pole of the moon, which is a very remote and unexplored region.

C. The lander and rover will need to be able to communicate with Earth, but the moon's atmosphere is very thin, which will make communication difficult.

D. All of the above.

Ans. D

Explanation: The Chandrayaan 3 mission will face a number of challenges, including the harsh lunar surface, the remote landing site, and the difficult communication conditions.

14. Which country is the fourth country to successfully land a spacecraft on the moon?

A. China

B. India

C. Russia

D.  USA

Ans. B

Explanation: The first three countries to successfully land a spacecraft on the moon were the United States, Russia, and China. India became the fourth country to do so on September 7, 2019, when the Chandrayaan 2 lander Vikram successfully touched down on the lunar surface.

15. What are the scientific instruments that will be carried by the lander and rover in Chandrayaan 3?

B. Atmospheric science instruments

C. Water science instruments

D. All of the above

Ans. D

Explanation: The Chandrayaan 3 mission will carry a variety of scientific instruments to study the moon. These instruments will be carried by the lander and rover, and they will study the composition and structure of the lunar surface, the composition and dynamics of the lunar atmosphere, and the search for water ice on the moon.
