Chandrayaan-2 (Sanskrit: चन्द्रयान-२; Template:IPA-sa; lit: Moon-craft About this soundpronunciation ) is India's second moon mission after Chandrayaan-1.[9] Made by the Indian Space Research Organisation (ISRO),[10][11] the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III).[6][7]

Launch of Chandrayaan-2 is scheduled for 14 July 2019 at 21:21 UTC.[5] A proper landing would make India the 4th country to achieve a soft landing on the Moon, after the space agencies of the USA, USSR, and China.[12] The mission landing is expected on 6 September 2019.[13]

History[change | change source]

On 12 November 2007, the Russian Federal Space Agency (Roscosmos) and ISRO agreed to work together on the Chandrayaan-2 project.[14] ISRO would be in charge of the orbiter and rover, while Roscosmos was to build the lander. [15] The design of the spacecraft was completed in August 2009, with scientists of both countries conducting a joint review.[16][17]

Although ISRO finalised the payload for Chandrayaan-2 on schedule, the mission was moved to 2016 because Russia was unable to build the lander on time.[18][19] When Russia decided it would not be able to build a lander by 2015, India decided to develop the lunar mission on its own.[20][21][22]

The spacecraft's launch had been scheduled for March 2018, but was delayed.[23][24] Two of the lander's legs got minor damage during one of the tests in February 2019, making the launch date even later.[25]
