An Overview of the news

With the success of ISRO’s Chandrayaan-3 mission, India became the fourth country after Russia (Soviet Union), America and China to have soft-landed on the Moon.
ISRO launched Chandrayaan-1 in 2008.
ISRO launched Chandrayaan-2 in 2019.
ISRO launched Chandrayaan-3 from Sriharikota on 14 July 2023.

Propulsion Module, Lander and Rover of Chandrayaan-3

In Chandrayaan-2 where there were Orbiter, Lander and Rover. Whereas, Chandrayaan-3 has a propulsion module, lander and rover.
The Lander + Rover of Chandrayaan-3 weighs about 250 kg more than the Lander + Rover of Chandrayaan-2.

How long will the missions last

Chandrayaan-3 is designed the propulsion module to work for 3 to 6 months, whereas Chandrayaan-2 had an estimated mission life of 7 years.
Chandrayaan-3 will move towards the moon more quickly than Chandrayaan-2.
4 thrusters have been installed in the lander of Chandrayaan-3. After a journey of about 40 days, Chandrayaan-3 will reach the surface of the moon. Chandrayaan-2 took 42 days to reach the moon.

Mission Cost

The cost of launching this mission is Rs 615 crore. While it has cost Rs 500 crore to launch it.

Objective of the Mission

The Chandrayaan-3 mission aims to gather more information about the lunar surface. For this, four types of scientific instruments have been installed on the lander. Which mainly:
- Earthquakes on the moon
- Surface thermal properties,
- Variation in plasma near the surface,
- Attempt to measure the exact distance between the Moon and the Earth,
- Will study the chemical and mineralogical composition of the lunar surface.

Mission Landing

The on-board computer decides how the landing will take place. The computer automatically takes decisions by estimating the location, height, velocity etc. according to its sensors.

What are the benefits of Chandrayaan-3 to the public and nation?

The Chandrayaan-3 mission has the potential to benefit the public and nation in many ways. Here are some of the benefits:

Scientific knowledge: The mission will help scientists to learn more about the Moon’s surface, subsurface, and composition. This knowledge could be used to develop new technologies and applications, such as new materials, new energy sources, and new ways to explore space.
Economic development: The mission could lead to the development of new industries and jobs, such as the space tourism industry and the space mining industry. This could help to boost the Indian economy.
National pride: The successful completion of the Chandrayaan-3 mission would be a major achievement for India and would boost national pride. It would show the world that India is a leading nation in space exploration.

Here are some specific scientific objectives of the Chandrayaan-3 mission:

To demonstrate safe and soft landing on the surface of the Moon.
To conduct rover operations on the Moon.
To conduct in-situ scientific experiments on the lunar surface.
To study the lunar South Pole region, which is thought to be rich in water ice.
To search for evidence of past or present life on the Moon.

The Chandrayaan-3 mission is a major undertaking, and it will require the cooperation of many different organizations and individuals. However, if it is successful, it will be a major milestone in India’s space program and will have a positive impact on the public and nation.

Achievement of Chandrayaan-2

Data from the orbiter attached to Chandrayaan-2 detected the presence of chromium, manganese and sodium for the first time through remote sensing. It will also provide more information about the magmatic evolution of the Moon.
