Chandrayaan-2 is the successor and advanced version of Chandrayaan-1 and will be India’s second lunar project. The mission was launched from Satish Dhawan Space Centre (SDSC) or Sriharikota Range (SHAR). SDSC is located in Sriharikota in Andhra Pradesh which is a rocket launch center operated by Indian Space Research Organisation (ISRO).

The program will constitute a lunar orbiter, a lander (Vikram- named in the honour of Vikram Sarabhai who is regarded as the father of Indian space programme), and a rover (Pragyan which means wisdom) and all have been produced within our domestic borders in a cost-effective manner.

If Chandrayaan-2 proves to be a successful mission, it will make India the fourth country in the world to soft land on the Moon after the ????????, ????????????????????, ???????????? ????????????????????????.

The orbiter is supposed to orbit 100 km from the lunar surface and the lander is supposed to do a soft landing near the south pole of the Moon.
ISRO Chairman, K Sivan said that it is an unexplored region and India will be the first country in the world if they are successful.
The rover is responsible for carrying out scientific experiments on the lunar surface.

Chandrayaan-2 also carried one payload from NASA which will be conducting a passive experiment.
NASA has supplied a special Laser Retro Reflector that India has placed on its lander and it will be used to measure accurately the distance between the Moon and the Earth. This instrument is being flown at no cost as a show of good faith.

1.The primary purpose of the mission is to showcase the ability to soft land on the lunar surface and operate a robotic rover on it.
Explore an unchartered territory- south pole of the Moon and ascertain circulatory patterns of water, if any.

2.Study and analyze the lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.

3.This will be studied by the six-wheeled rover which will be semi-autonomously controlled from the ISRO ground stations.

Chandrayaan was derived from ancient Sanskrit which means moon vehicle. It was the first lunar mission undertaken by India thus making us the fourth country in the world to place its flag on the Moon. The Chandrayaan project in India was during the tenure of Dr. Manmohan Singh . The estimated cost of the project was 386 crore rupees. Chandrayaan-1 was launched from the Satish Dhawan Space Centre at Sriharikota island, India on 22 October 2008 and reached the moon on 8 November 2008. The satellite made 3400 orbits of the Moon until 29 August 2009, after which controllers completely lost all communication with the spacecraft and ISRO declared the mission to be concluded. Even though Chandrayaan-1 terminated a year before its planned end, it is an incredible success and has been successful in achieving 95% of its targets.

The sub-satellite launched on the surface of the moon is known as Moon Impact Probe and was the brainchild of APJ Abdul Kalam.

Why was Chandrayaan-1- the country’s unmanned maiden moon mission celebrated as a success?

Chandrayaan-1 released the Moon Impact probe from a height of 100 km which recorded evidence of water ice on the Moon. However, the news was released only after NASA confirmed it. Lunar scientists had been discussing the possibility of water for decades and ISRO was the first space organisation to prove its existence.

Chandrayaan-1 successfully sent images of a lunar rille which is basically a type of large cave. Tunnels near the lunar equator were discovered which are non-volcanic in nature and are considered to be potential human settlement sites.
