- 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.
Complexities involved in a moon landing
- 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.
