Overview

India’s third Moon mission, Chandrayaan-3, launched from the Sriharikota launch pad.

The mission aims to put an end to Chandrayaan-2’s disaster, which occurred when it crashed into the lunar surface in 2019.

Even though India began our space mission considerably later than other nations, those who had already landed before us were unable to get the information that Chandrayaan had discovered.
Now, this Chandrayaan 3 will expand those trials that suggest or allude to the potential for human habitat on the Moon at some point in the future.
The outcomes will be favorable to India on a number of levels.
It has elevated India to the top position in the world in terms of both space technology and the space industry.
Chandrayaan-3 aims to achieve what its predecessor, Chandrayaan-2, was unable to accomplish during its attempted soft landing.

When Chandrayaan-3 launched?

Which city launched Chandrayaan-3?

Which launcher is used for the launch?

The launcher identified for Chandrayaan-3 is GSLV-Mk3
It will place the integrated module in an Elliptic Parking Orbit (EPO) of size ~170 x 36500 km.

What was the objective of Chandrayaan-3?

To show Safe and Soft Landing on the Surface of the Moon
To showcase roaming lunar rover technology
To carry out in-situ scientific research.
Several cutting-edge technologies are required and demostrated accomplish the mission’s goals.

What are the different modules of Chandrayaan-3?

The propulsion module will carry the lander and rover configuration till 100 km lunar orbit
- The lander and rover combination will be carried by the propulsion module up to a 100 kilometre lunar orbit.
- To examine the spectral and Polarimetric data of Earth from the lunar orbit, the propulsion module is equipped with the Spectro-Polarimetry of Habitable Planet Earth (SHAPE) payload.
Lander module capability to soft land and deploy Rover
- The Lander will have the capability to soft land at a specified lunar site.
- To gauge the temperature and thermal conductivity
- Monitoring the seismicity at the landing site using the Instrument for Lunar Seismic Activity (ILSA)
- To determine the plasma density and its changes, use the Langmuir Probe (LP).
- For lunar laser ranging investigations, space agency NASA has provided a passive Laser Retroreflector Array.
Rover will carry out in-situ chemical analysis of the lunar surface
- Rover which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility.
- For determining the elemental composition close to the landing site, scientists use the laser-induced breakdown spectroscope (LIBS) and the alpha particle X-ray spectrometer (APXS).

The payloads on the lander and rover remain the same as the last mission
