Chandrayaan-3 (candra-yāna, transl. "mooncraft";[3][4] pronunciation) 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, but it's propulsion module will behave like a communications relay satellite.[7][8] The spacecraft is planned to be launched in 2023.[1] The rocket for the launch of the spacecraft was declared ready and awaits the module.[9]


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.[10][11]

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.[12][13]

The 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.[14] During mission critical flight operations ESTRACK operated by ESA will support the mission according to a contract.[15]


The lander for Chandrayaan-3 will have only four throttle-able engines,[16] unlike Vikram on Chandrayaan-2 which had five 800 Newtons engines with a fifth one being centrally mounted with a fixed thrust. Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV).[17]


In December 2019, it was reported that ISRO requested the initial funding of the project, amounting to 75 crore (US$9.4 million), out of which 60 crore (US$7.5 million) will be for meeting expenditure towards machinery, equipment and other capital expenditure, while the remaining 15 crore (US$1.9 million) is sought under revenue expenditure head.[18]

Confirming the existence of the project, ISRO's chairman K. Sivan stated that the cost would be around 615 crore (equivalent to 724 crore or US$91 million in 2023).[19]
