Chandrayaan-3 (candra-yāna, transl. "mooncraft";[3][4] About this soundpronunciation (help·info)) is a planned third lunar exploration mission by the Indian Space Research Organisation (ISRO).[5]

Following Chandrayaan-2, where a last-minute glitch in the soft landing guidance software led to the failure of the lander's soft landing attempt after a successful orbital insertion, another lunar mission for demonstrating soft landing was proposed.[6] Chandrayaan-3 will be a mission repeat of Chandrayaan-2 but will only include a lander and rover similar to that of Chandrayaan-2. It will not have an orbiter.[7] The spacecraft is planned to be launched in the third quarter of 2022.[1]

Background[]

In the second phase of the Chandrayaan programme to demonstrate soft landing on the Moon, ISRO launched Chandrayaan-2 onboard a GSLV Mk III launch vehicle consisting of an orbiter, a lander and a rover. The lander was scheduled to touchdown on the lunar surface in September 2019 to deploy the Pragyan rover.[8][9]

Earlier reports had emerged about a collaboration with Japan on a mission to the lunar south pole where India would be providing the lander while Japan would provide both launcher and rover. The mission may include site sampling and lunar night survival technologies.[10][11]

Subsequent failure of the Vikram lander led to the pursuit of another mission to demonstrate the landing capabilities needed for the Lunar Polar Exploration Mission proposed in partnership with Japan for 2024.[12] The launch of spacecraft is scheduled at sometime in first half of 2022.[13]

Design[]

The lander for Chandrayaan-3 will have only four throttle-able engines [14] unlike Vikram on Chandrayaan-2 which had five 800 Newtons engines with a fifth one being centrally mounted and with fixed thrust. Additionally the Chandrayaan-3 lander will also be equipped with a (LDV).[15]

Funding[]

In December 2019, it was reported that ISRO requested the initial funding of the project, amounting to ₹75 crore (US$11 million), out of which ₹60 crore (US$8.4 million) will be for meeting expenditure towards machinery, equipment and other capital expenditure, while the remaining ₹15 crore (US$2.1 million) is sought under revenue expenditure head.[16]

Confirming the existence of the project, ISRO's chairman K. Sivan stated that the cost would be around ₹615 crore (US$86 million).[17]
