Finally, on 22nd July, 2019 at 02:43 PM , The Second Lunar Exploration Mission has Successfully initiated by ISRO from (Sriharikota Space Centre) The Satish Dhawan Space Centre Second Launch Pad.While it will take another 48 days for Vikram, the lander, to soft-land on Moon, Monday’s launch has Isro in good spirits, given the fact that the agency had to cancel its first scheduled launch on July 15 after discovering a leak in the cryogenic stage of GSLV-MkIII.

Chandrayaan-2 is more complex than Chandrayaan-1, costing more than double the first mission cost— Rs 978 crore compared to less than Rs 400 crore — as it will soft land Vikram (the lander) and Pragyan (the rover) in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south, on 7th September.
Chandrayaan-2 has carried 14 scientific instruments to Moon, including a passive payload from NASA.
The aim is to improve understanding of the Moon and make discoveries that will benefit humanity.
Isro claims Chandrayaan-2 will go to that part of the moon where no country has ever gone before : The south polar region.
The South Pole is especially interesting because the lunar surface area here that remains in shadow is much larger than that at the North Pole.
There’s a possibility of presence of water in permanently shadowed areas around it.
After Chandrayaan-2, the Indian Space Research Organisation (ISRO) has planned to launch its solar mission, Aditya-L1, during the first half of 2020.
Aditya-L1 is meant to observe the Sun’s corona, the outer layers of the star that span thousands of kilometres.
The primary objectives of Chandrayaan-2 are to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface. Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice. The orbiter will map the lunar surface and help to prepare 3D maps of it. The onboard radar will also map the surface while studying the water ice in the south polar region and thickness of the lunar regolith on the surface. Chandrayaan-2 will inform the location and abundance of lunar water for exploitation by the future lunar base proposed by the Artemis program.
In 2014, India became the first Asian nation to reach the Red Planet, when it put the Mangalyaan probe into orbit around Mars.India is now on the way to becoming the fourth country — in addition to United States, China and the former Soviet Union — to make a soft-landing on the lunar surface.
