Chandrayaan2 mission

CHANDRAYAAN-2

    Chandrayaan-2 is India's second lunar exploration mission after Chandrayaan-1. 

Developed by the Indian Space Research Organisation (ISRO) , the mission is planned

to be launched to the Moon by Geosychronous Satelite Launch Vechicle Mark III 

(GSLV MK III). It include a lunar orbiter, lander and rover, all developed inedigenopusly.

Chandrayaan-2 will attempt a soft landing of a lander and rover in high plain between two craters, Manizinus C and Simpelius N , at a latitude of about 70 degree south. The wheeled rover , will move on the lunar surfave and will perform on site chemical ana-

      lysis. It can relay data to Earth through the Chandrayaan-2 orbital and lander , which 

will fly on the same launch.

Launch of Chandrayaan-2 is scheduled for 14 July,2019 at 21:21 UTC. A successful 

landing would make India the 4th country in the world to achive a soft landing on

the Moon, after the space agencies of the USA , USSR , China. If successful Chandrayaan

-2 will be the First ever mission to soft land near the lunar South pole.

History :

On 12 November 2007 , respresentative of the Russian Federal Space Agency (Roscomos) and ISRO

signed an agreement for the two agencies to  work together on the Chandrayaan-2 project. ISRO would have the Prime responsibility for the orbiter and rover , while Roscomos was to provide the lander. the Indian Government approved the mission in a meeting of the Union Cabinet , held on 

18 September 2008 and chaired by Prime Minister Manmohan Singh. The design of the spacecraft 

was completed in August 2009 , with scientists of both countries conducting a joint review.

Although ISRO finalised the payload for Chandrayaan-2 per schedule , the mission was postponed 

in January 2013 and rescheduled to 2016 because Russia was unable to develope the lander on time.

Roscomos later withdrew in wake of the failure of the Fobos- Grunt mission to Mars , since the technical aspects connected eith the Fobos-Grunt mission were also used in the lunar projects , while 

needed to be reviewed. When Russian cited its inability to provide the lander even by 2015 , India decide to develope the lunar mission independently.

The spacecraft's launch had been scheduled for March 2018, but was first delayed to April and then 

to October to conduct further tests on tje vechicle. On 19 June 2018 , after the program's fourth 

Comprehensive Technical Review meeting , a numberof changes in configuration and landing 

sequence were planned for implememtation , pushing the launch to the first half of 2019.

Two of the lander legs got minor damage during one of the tests in February 2019.

Chandrayaan-2 launch was scheduled for 14 July 2019. 21:21 UTC (15 July 2019 at 02:51 IST local time). With the landing expected on 6 Sepetmber 2019. However , the launch was aborted due to a technical  glitch and rescheduled to 22 july 2019.


Objetives :

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
