Chandrayaan-2 Mission | 13 Jun 2019

For the first time in the history of Indian Space Research Organisation (ISRO), two women will head the Chandrayaan-2 mission.

Ritu Kridhal and M Vanitha are leading as project and mission directors respectively for Chandrayaan-2 mission.

Chandrayaan-2 is India's second lunar exploration mission after Chandrayaan-1, developed by the Indian Space Research Organisation.

Quantify the water available on the moon’s surface.
Map its topography, to explore chemicals and minerals such as magnesium, iron, and Helium.
Study topmost part of the lunar atmosphere.

Global Power: If successful, India will be the fourth country (After Russia, China, and the USA) to land a rover on the moon.
- India will be the first country to land on the southern pole of the moon.
- This would give ISRO opportunity to name that site on the moon.
Indigenous mission: 13 instruments from India, one instrument from US space agency, NASA.
Future Space Exploration: mission will also expand the country’s footprint in space as moon is the perfect test-bed for proving technologies required for future space exploration.

Trajectory accuracy: Ensuring trajectory accuracy while navigating 3.844 lakh km has its own challenges.
Communication hurdle: Owing to the large distance from Earth, radio signals, which need to be picked up, would be weak.
Lunar dust: Firing engines close to the lunar surface results in the backward flow of gases and dust, causing hindrance to deployment mechanism and damaging sensors.
Extreme temperatures: A lunar day or night lasts 14 earth days, resulting in extreme surface temperature.
Trans-lunar injection, capture: Series of engine burns to get close to the moon, intersection of probe and moon must be predicted in advance with accuracy.
Orbiting: The lumpy lunar gravity influences the orbit of the spacecraft.
