Important Points about Chandrayaan-2 that You must Know

Chandrayaan-2: Moon is the only Satellite of the Earth. The whole world is trying to capture the Moon and use the Moon for their future utilization and requirements.

Chandrayaan-2 the Study of Moon

In the year 1979  USA landed the first two people on the Moon surface and created a History in the world. Neil Armstrong was the first Person who put first footprints on the surface of the Moon. After 1969 many attempts have been made by different countries. Some countries like Russia, India, China, Japan, European Space Agency (ESA) have got successfully completed the Moon Mission.

In the year 2008, India launched its first Moon mission Project named as Chandrayaan-1. India reached the orbit of the Moon within a few days. India was the first country who discovered the Presence of water in the Moon with the help of Chandrayaan-1.


Chandrayaan-1 also has gathered some more information about the Moon.Now the whole world is trying to study the surface of the moon and to make the moon suitable for human living.

Chandrayaan-2 (Mission to Moon)


After the success of Chandrayaan-1, ISRO (Indian Space Research Organization) is planning to launch the second edition of the Moon mission named as Chandrayaan-2.

ISROChandrayaan-2 is one of the finest and well developed Moon mission, which will inform the hidden mystery of the Moon.

Modules of Chandrayaan-2

The Chandrayaan-2 is developed and fully designed in India by Indian Space Research Organization (ISRO). We can say that Chandrayaan-2 is fully made in India. Chandrayaan-2  is designed with the latest technology and modern innovation of India. It has four modules:

  1. Launcher
  2. Orbitor
  3. Lander
  4. Rover

Modules of chandrayaan-2

Let us discuss each and every modules in details:


Chandrayaan-2 is launched with the help of India’s most powerful launcher GSLV mk-3 (Geosynchronous Satellite Launch Vehicle mark-3).

GSLV Mk-3 launcher

It has mainly 3 Components:

  1. S200 Solid Rocket Booster
  2. L110 Liquid Stage
  3. C25 Upper
  4. Stage

The Orbitor of Chandrayaan-2 is one of the main parts of Chandrayaan-2.

Orbitor Of Chandrayaan-2

The Orbitor is just like the earth’s artificial satellite. It will be placed in 100Km away from the surface of the moon. The Orbitor will fetch data from the lander Vikram and will re-transmit  the data to IDSN (Indian Deep Space Network), which is located at Byalalu, Bangalore. It’s life time of work is about 1 year.


In Chandrayaan-2 lander is the security and driver of the mission. The lander is named with “Vikram”. Vikram is named as per the name of the father of Indian space Dr. Vikram A Sarabhai. The lander Vikram is fully made in India and developed in India. The lander Vikram will make a soft landing on the surface of earth. Its algorithm is also  developed in India.

Lander Vikrant of Chandrayaan-2

Its weight is about 1471 Kg and it has a power rating of 650w. It will function for one lunar days (1 lunar Day= 14 Earth days). Lander Vikram will receive data from the Rover Pragyan and will emit the data to Orbitor of Moon and IDSN Centre.

Rover (Pragyan)

In Chandrayaan-2 ISRO has attached India’s most advanced developed Robotics vehicle named as Pragyan. Pragyan refers to ‘Wisdom’ in Sanskrit language. Its all parts, software and algorithm is fully designed and developed in India. After a smooth landing of Lander Vikram on the surface of the Moon, Rover Pragyan will start its work by absorbing Solar Light.

Pragyan Rover of Chandrayaan-2

It will collect data by moving 500m (½ Km) and will transmit the collected data to the Lander near it.

Working and Steps of Chandrayaan-2

Chandrayaan-2 is going to create a record in Indian Space Research History. Firstly, it was scheduled that Chandrayaan-2 will be launched on 15th July, 2019 at 2.51 hrs from the Satish Dhawan Space Centre (Sriharikota, Andhra Pradesh). Due to technical snag, it was called off before one hour of launch. After resolving the technical snacks it was scheduled to launch Chandrayaan-2 on 22nd July, 2019 at 14:43 hours (02:43 PM) IST.

Chandrayaan-2 road map

  • First of all, Chandrayaan-2 was launched through the powerful GSLV Mk-3 rocket launcher.
  • After travelling some distance GSLV-3 and other parts were separated and orbiter was injected into the Earth’s Parking Object (EPO: 170 x 39120 km).
  • It will make five revolutions around the earth as per the above figure.
  • Then it will be forced to enter into the Lunar orbit.
  • Now it will make some revolutions around the moon’s orbit.


  • After some days Lander will be separated from the orbiter.
  • Now Lander will scan the surface of the moon and will select the suitable place for landing.
  • Now lander will make a smooth landing on the selected place.
  • Within some hours Rover Pragyan will come out from the Lander and will start its work for next 7 earth days.
This how Chandrayaan-2 will Work.
