Thus, India became the first nation to soft-land on the surface of the Lunar south pole and overall the fourth to do a soft landing anywhere on the Earth\u2019s natural satellite. Indian Space Research Organisation launched the Chandrayaan-3 Mission by using the Geosynchronous Satellite Launch Vehicle Mark III (LVM3) on 14th July 2023 from Sriharikota.<\/p>\r\n<p>With the objective to demonstrate the ability to soft landing and roving as well as to carry out experiments on the lunar surface, the Chandrayaan 3 Mission aims to strengthen India's prowess in space discovery and innovation. Continuing the success of its predecessors (Chandrayaan-1 and Chandrayaan-2), the Mission has brought India into the exclusive elite space club.<\/p>\r\n<h2>What is the Chandrayaan 3 Mission?<\/h2>\r\n<p>The Chandrayaan 3 Mission was launched using the LVM3 rocket system. LVM3 is the new launch vehicle of ISRO with the capability to place the modules into the GTO (Geosynchronous Transfer Orbit) in a cost-effective manner.\u00a0It is a three-stage launch vehicle with two solid strap stages and one core liquid stage. The Launcher, LVM3 M4, placed the integrated Modules in an Elliptic Parking Orbit of size approx. 170 x 36500 km (a GTO).<\/p>\r\n<h3>Objectives of Chandrayaan 3 Mission<\/h3>\r\n<p>One of the many goals of the Mission is to look for water ice that could support future human life on the Moon and also for supplying propellants for spacecraft in future interplanetary missions.
