What Is the Mission Chandrayaan-3?

Chandrayaan-3 is India’s third lunar exploration mission, built upon the learnings and aspirations of its predecessors. With its main objective to push the boundaries of lunar research, this mission captures the imagination of space enthusiasts everywhere. As you prepare for a quiz on Chandrayaan 3, exploring this mission will surely boost your knowledge.

Chandrayaan-3 : An Overview

After the partial success of the Chandrayaan-2 mission (the orbiter successfully entered lunar orbit, but the lander Vikram crashed-landed on the Moon’s surface), the Indian Space Research Organisation (ISRO) launched another mission, Chandrayaan-3 (1).

Key Points of the Mission :

1. No Orbiter: Unlike Chandrayaan-2, Chandrayaan-3 is primarily a landing mission. Since the Chandrayaan-2 orbiter is still operational and sending data from lunar orbit, Chandrayaan-3 does have a separate orbiter. Instead, it focuses on the lander and rover components (2).

2. Enhanced Lander Design: Learning from the Chandrayaan-2 lander’s unsuccessful soft-landing attempt, ISRO has incorporated significant design changes and improvements for the Chandrayaan-3 lander to ensure a successful landing on the Moon’s surface.

3. Mission Objectives: The primary objective is to demonstrate the ability to operate a robotic rover on the Moon and soft-land on the lunar surface. This rover conducts experiments, collects data, and relays it to Earth, providing valuable insights into the Moon’s geology, composition, and other attributes.

4. Collaborations: There was discussion about international collaboration for some instruments and technology, although ISRO was at the forefront of the mission’s execution.

5. Launch Timeline: Chandrayaan-3 started its voyage to the Moon on its designated trajectory. The lift-off is set for July 14, 2023, at 14:35 Hrs.

6. Location: On August 23, 2023, the Chandrayaan-3, under the auspices of ISRO (Indian Space Research Organisation), landed on the Moon. The landing zone is roughly 600 kilometres from the Moon’s South Pole. Four days post-landing, the LROC (LRO Camera) captured a slanted image (at a 42-degree angle) of the lander. The noticeable bright circle surrounding the lander was caused by the rocket’s exhaust interacting with the Moon’s fine soil, known as regolith.

Answers

Q1. Ans. (b) To soft-land on the Moon’s south pole

While the Chandrayaan-3 mission has several objectives, its primary goal is to demonstrate the ability to soft-land on the lunar surface. The mission focuses on landing and operating a robotic rover on the Moon, especially since the Chandrayaan-2 orbiter is still functional and transmitting data.

Q2. Ans. (d) ISRO (Indian Space Research Organisation)

The Chandrayaan-3 mission is an initiative of the Indian Space Research Organisation (ISRO). ISRO is India’s national space agency and has been at the forefront of the country’s space exploration efforts, including the Chandrayaan series of lunar missions.

Q3. Ans. (c) Chandrayaan-2

Chandrayaan-3 is the follow-up mission to Chandrayaan-2, aimed at accomplishing a successful soft landing on the Moon after the Chandrayaan-2 lander faced challenges during its landing attempt.

Q4. Ans. (d) Orbiter

Chandrayaan-3 does not include an orbiter because the Chandrayaan-2 orbiter is still operational and transmitting valuable data from lunar orbit.

Q5. Ans. (d) South Pole

Chandrayaan-3’s anticipated landing region is near the Moon’s south pole, which holds significant interest due to the presence of water ice and unique environmental conditions.

Q6. Ans. (c) Vikram 2

The successor to the Vikram lander (Chandrayaan-2) is often colloquially referred to as “Vikram 2”.

Q7. Ans. (b) Six

Like its predecessor in Chandrayaan-2, the rover for the Chandrayaan-3 mission is designed with six wheels for optimal mobility on the lunar surface.

Q8. Ans. (b) 14 Earth days

The Chandrayaan-3 rover, like its predecessor from Chandrayaan-2, is expected to have a mission life of approximately 14 Earth days, roughly equivalent to one lunar day.

Q9. Ans. (b) Sanskrit

The word ‘Chandrayaan’ comes from Sanskrit, where “Chandra” means “Moon” and “Yaan” means “Vehicle” or ‘Craft.’

Q10. Ans. (c) Aitken Basin

The South Pole-Aitken Basin is of great interest due to its unique geology and the potential presence of water ice. Chandrayaan-3 is expected to explore this region.

Q11. Ans. (c) Vikram

Vikram was the lander component of Chandrayaan-2. Unfortunately, it crashed on the Moon’s surface in September 2019.

Q12. Ans. (c) Helium-3

Helium-3, an isotope of helium, is believed to be abundant on the Moon and a potential fuel for future nuclear fusion power.

Q13. Ans. (c) A controlled landing without damage to the spacecraft

A ‘soft landing’ refers to a controlled descent and landing, ensuring the spacecraft lands without damage, enabling it to carry out its intended mission on the surface.

Q14. Ans. (c) NASA

NASA’s Artemis program aims to land ‘the first woman and another man’ on the Moon by the mid-2020s and establish a sustainable human presence there by the decade’s end.

Q15. Ans. (c) Communicating with the spacecraft

ISRO’s Deep Space Network (DSN) is pivotal in tracking and communicating with distant spacecraft, including the Chandrayaan missions.
