== Objective ==

ISRO has set three main objectives for the Chandrayaan-3 mission, which include:

# In-site observation & conducting experiments on the materials available on the lunar surface to better understand  composition of the Moon.<ref>{{Cite web |title=Indian Space Research Organisation |url=https://www.isro.gov.in/ |access-date=2023-07-14 |website=www.isro.gov.in |archive-date=2 October 2019 |archive-url=https://web.archive.org/web/20191002232539/https://www.isro.gov.in/ |url-status=live }}</ref>

After a series of Lunar Bound Maneuvers, on August 17, the Vikram lander separated from the relay satellite, to begin its solo journey to the lunar surface. The next maneuver will be conducted on August 18, which will lower the perigee (closest point) of the orbit in preparation of the landing.

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}}and a apogee of {{convert|36,500|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.
