Expanding the boundaries of human knowledge

Chandrayaan-2 mission is a highly complex mission, which represents a significant technological leap compared to the previous missions of ISRO, which brought together an Orbiter, Lander and Rover with the goal of exploring south pole of the Moon. This is a unique mission which aims at studying not just one area of the Moon but all the areas combining the exosphere, the surface as well as the sub-surface of the moon in a single mission.

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.

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.

The Lunar South pole is especially interesting because of the lunar surface area that remains in shadow is much larger than that at the North Pole. There could be a possibility of presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.

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.


Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III)

The GSLV Mk-III will carry Chandrayaan 2 to its designated orbit. This three-stage vehicle is India's most powerful launcher to date, and is capable of launching 4-ton class of satellites to the Geosynchronous Transfer Orbit (GTO).

Launcher

Its components are:
S200 solid rocket boosters
L110 liquid stage
C25 upper stage


Orbiter

Weight
2,379 kg
Electric Power Generation Capability
1,000 W
Chandrayaan 2 Orbiter is capable of communicating with Indian Deep Space Network (IDSN) at Byalalu as well as the Vikram Lander. The precise launch and mission management has ensured a mission life of almost seven years instead of the planned one year.

Lander — Vikram

Weight
1,471 kg
Electric Power Generation Capability
650 W
The Lander of Chandrayaan-2 was named Vikram after Dr Vikram A Sarabhai, the Father of the Indian Space Programme. It was designed to function for one lunar day, which is equivalent to about 14 Earth days.

Electric Power Generation Capability
50 W
Chandrayaan-2’s Rover was a 6-wheeled robotic vehicle named as Pragyan, which translates to 'wisdom' in Sanskrit.
