Chandrayaan-2 mission explained

Chandrayaan-2 (candra-yāna, transl. "mooncraft";[15][16] About this soundpronunciation ) is the second lunar exploration mission developed by the Indian Space Research Organisation (ISRO),[17][18] after Chandrayaan-1.[19][20] It consists of a lunar orbiter, the Vikram lander, and the Pragyan lunar rover, all of which were developed in India.[21] The main scientific objective is to map and study the variations in lunar surface composition, as well as the location and abundance of lunar water.[22][23]

The mission was launched on its course to the Moon from the second launch pad at Satish Dhawan Space Centre on 22 July 2019 at 2.43 PM IST (09:13 UTC) by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III).[9][10][24] The craft reached the Moon's orbit on 20 August 2019 and began orbital positioning manoeuvres for the landing of the Vikram lander.[25] Vikram and the rover were scheduled to land on the near side of the Moon, in the south polar region[26] at a latitude of about 70° south at approximately 20:23 UTC on 6 September 2019 and conduct scientific experiments for one lunar day, which approximates two Earth weeks.

However, the lander deviated from its intended trajectory starting at 2.1 kilometres (1.3 mi) altitude,[27] and had lost communication when touchdown confirmation was expected.[28][29] Initial reports suggesting a crash[30][31] have been confirmed by ISRO chairman K. Sivan, stating that the lander location had been found, and "it must have been a hard landing".[32]

As of 8 September 2019, on-going efforts are being made by ISRO in hopes of restoring communications with Vikram. Both ISRO and NASA are in the process of trying to restore communications through their respective Deep Space Networks. Communication attempts will likely cease on 21 September 2019, fourteen days after Vikram's landing attempt. The orbiter, part of the mission with eight scientific instruments, remains operational and is expected to continue its seven-year mission to study the Moon.


On 12 November 2007, representatives of the Russian Federal Space Agency (Roscosmos) and ISRO signed an agreement for the two agencies to work together on the Chandrayaan-2 project.[33] ISRO would have the prime responsibility for the orbiter and rover, while Roscosmos 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.[34] The design of the spacecraft was completed in August 2009, with scientists of both countries conducting a joint review.[35][36]

Although ISRO finalised the payload for Chandrayaan-2 per schedule,[37] the mission was postponed in January 2013[38] and rescheduled to 2016 because Russia was unable to develop the lander on time.[39][40] Roscosmos later withdrew in wake of the failure of the Fobos-Grunt mission to Mars, since the technical aspects connected with the Fobos-Grunt mission were also used in the lunar projects, which needed to be reviewed.[39] When Russia cited its inability to provide the lander even by 2015, India decided to develop the lunar mission independently.[38][41]

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 the vehicle.[42][43] On 19 June 2018, after the program's fourth Comprehensive Technical Review meeting, a number of changes in configuration and landing sequence were planned for implementation, pushing the launch to the first half of 2019.[44] Two of the lander's legs got minor damage during one of the tests in February 2019.[45]

Chandrayaan-2 launch was initially scheduled for 14 July 2019, 21:21 UTC (15 July 2019 at 02:51 IST local time), with the landing expected on 6 September 2019.[20] However, the launch was aborted due to a technical glitch and was rescheduled.[46][8][47] The launch occurred on 22 July 2019 at 09:13 UTC (14:43 IST) on the first operational flight of a GSLV MK III M1.[48]
