'''Chandrayaan-3''' ( | '''Chandrayaan-3''' (Devanagari: चन्द्रयान-3) is the third and most recent lunar Indian Space Research exploration mission under the [[Chandrayaan programme]]. It consists of a lander named [[Vikram (spacecraft)|Vikram]] and a rover named ''[[Pragyan (rover)|Pragyan]]'' similar to [[Chandrayaan-2]], but does not have an orbiter. Its propulsion module behaves like a communication relay satellite. The propulsion module carries the lander and rover configuration until the spacecraft is in a 100 km lunar orbit.<ref name=":0">{{cite web |date=2 January 2020 |title=Chandrayaan-3 to cost Rs 615 crore, launch could stretch to 2021 |url=https://timesofindia.indiatimes.com/india/chandrayaan-3-to-cost-rs-615--crore-launch-could-stretch-to-2021/articleshow/73055941.cms |access-date=3 January 2020 |newspaper=The Times of India |archive-date=19 November 2021 |archive-url=https://web.archive.org/web/20211119155006/https://timesofindia.indiatimes.com/india/chandrayaan-3-to-cost-rs-615--crore-launch-could-stretch-to-2021/articleshow/73055941.cms |url-status=live }}</ref><ref name=":1">{{cite web |title=NASA - NSSDCA - Spacecraft - Details |url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=CHANDRYN3 |access-date=10 June 2022 |archive-date=8 June 2022 |archive-url=https://web.archive.org/web/20220608231611/https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=CHANDRYN3 |url-status=live }}</ref> | ||

Chandrayaan-3 was launched on 14 July 2023, at 2:35 pm IST as scheduled, from [[Satish Dhawan Space Centre]] [[Second Launch Pad]] in [[Sriharikota]], [[Andhra Pradesh]], India. The spacecraft has been effectively placed in the trajectory it will take to reach the moon. It is anticipated that the Chandrayaan-3 mission will achieve a soft landing on the lunar South Pole region on 23 August.<ref>{{cite web | url=https://scroll.in/latest/1052635/chandrayan-3-lifts-off-for-mission-to-moon | title=Chandrayan-3 lifts off on mission to the moon | date=14 July 2023 | access-date=14 July 2023 | archive-date=17 July 2023 | archive-url=https://web.archive.org/web/20230717125057/https://scroll.in/latest/1052635/chandrayan-3-lifts-off-for-mission-to-moon | url-status=live }}</ref> | |||
Choosing the month of July for the launch of Chandrayaan 3 was a special move because of a calculation made by ISRO regarding the closeness of Earth and Moon.<ref>{{Cite web |date=2023-07-14 |title=Chandrayaan 3: Know why July is important for ISRO |url=https://www.news9live.com/knowledge/chandrayaan-3-know-why-july-is-important-for-isro-2213186 |access-date=2023-07-14 |website=News9live |language=en-US |archive-date=17 July 2023 |archive-url=https://web.archive.org/web/20230717125111/https://www.news9live.com/knowledge/chandrayaan-3-know-why-july-is-important-for-isro-2213186 |url-status=live }}</ref> | |||
On August 5, the [[Indian Space Research Organisation]] achieved a successful Lunar-Orbit Insertion (LOI), successfully placing the Chandrayaan-3 spacecraft into orbit around the [[Moon]]. The LOI operation was carried out from the ISRO Telemetry, Tracking, and Command Network (ISTRAC) located in [[Bengaluru]]. The manoeuvre commenced at 7 p.m. and was completed with precision. This significant achievement marks a significant milestone in India's space exploration efforts and brings the Chandrayaan-3 mission closer to its intended objectives. <ref>{{cite web |last1=THE HINDU BUREAU |title=Chandrayaan-3 spacecraft enters lunar orbit |url=https://www.thehindu.com/sci-tech/science/chandrayaan-3-enters-lunar-orbit/article67161942.ece |website=The Hindu |access-date=6 August 2023}}</ref><ref>{{Cite web |last=Grey |first=Charles |date=2023-08-06 |title=India's Chandrayaan-3 Successfully Inserted Into Lunar Orbit |url=https://airspacenews.net/indias-chandrayaan-3-successfully-inserted-into-lunar-orbit/ |access-date=2023-08-06 |website=AIR SPACE News |language=en-US}}</ref> | |||

==Orbit raising and station keeping== | |||
The satellite was launched aboard the [[LVM3]]-M4 rocket in the afternoon of 14 July 2023, at 2:35 pm IST to a [[Parking orbit|EPO]] perigee of {{convert|170|km|mi|0|abbr=on}}. This will be followed by a series of orbit raising operations (using an on-board [[Liquid Apogee Motor|LAM]] and chemical thrusters to place the satellite in the [[Trans-lunar injection]] orbit. | |||
