Space mission :

Chandrayaan-2 is the second lunar exploration mission developed by the Indian Space Research Organisation, after Chandrayaan-1. As of September 2019, it consists of a lunar orbiter, and also included the Vikram lander, and the Pragyan lunar rover, all of which were developed in India.

Is Chandrayaan 2 successful :

Chandrayaan2 was the most complex mission ever attempted by India’s space agency, Isro. Its chairman K Sivan – who had earlier described the final descent as “15 minutes of terror” – has since said the mission was “98% successful“, based on the findings of an official commitee.

Why did we go to the Moon?

The Moon is the closest cosmic body at which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan-2 aims for enhancing our understanding of the Moon, stimulate the advancement of technology, promote global alliances and inspire a future generation of explorers and scientists.

Launcher and the Spacecraft


The GSLV Mk-III is India’s most powerful launcher to date, and has been completely designed and fabricated from within the country.

What are the scientific objectives of Chandrayaan 2 ?

Why was the Lunar South Pole targetted for exploration?

Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Though there are a few mature models, further explanations were needed to understand the origin of the Moon. Extensive mapping of lunar surface to study variations in lunar surface were essential to trace back the origin and evolution of the Moon. Evidence for water molecules discovered by Chandrayaan-1, required further studies on the extent of water molecule distribution on the surface, below the surface and in the tenous lunar exosphere to address the origin of water on Moon.

Science experiments :

Chandrayaan-2 has several science payloads to expand the lunar scientific knowledge through detailed study of topography, seismography, mineral identification and distribution, surface chemical composition, thermo-physical characteristics of top soil and composition of the tenuous lunar atmosphere, leading to a new understanding of the origin and evolution of the Moon.
