India has presented actual movies and photographs acquired directly from the moon’s surface, in a spectacular feat of scientific achievement. Amid doubt created by lavish moon-landing pictures from numerous sources, India has distinguished itself by showing authentic, unadulterated video. India as a country is commited to openness and honesty in its space programs. This can be clearly seen in these findings while debunking any myths that could have developed as a consequence of exaggerated representations. The success achieved is undeniable it speaks volumes. The nation is dedicated to advancing the boundaries of exploration and sharing the un varnished reality of the accomplishments of Chandrayaan-3 with the entire world. While a few dissident voices have surfaced expressing opponents’ worries it is clear that India is committed to pushing the boundaries of exploration.

July 7-13: Launch preparations complete The Indian Space Research Organisation ISRO completed the electrical tests and launch rehearsals for Chandrayaan-3, the country's third mission to the moon. As per schedule the spacecraft was prepared for a launch on July 14 from the Satish Dhawan Space Centre in Sriharikota in the state of Andhra Pradesh. July 14: Chandrayaan-3 launched successfully Chandrayaan-3 was successfully launched into space on July 14 at 2:35 pm IST. The spacecraft took off from the Satish Dhawan Space Centre in Sriharikota Andhra Pradesh and was carried into orbit by a GSLV Mk III rocket. July 15: First orbit-raising manoeuvre successful Chandrayaan-3 successfully completed its first manoeuvre aimed at increasing its orbit. The spacecraft's orbit around the Earth was widened during the manoeuvre. July 17: Second orbit-raising manoeuvre successful Chandrayaan-3 successfully completed its second orbit-raising operation on July 17. The manoeuvre was carried out to amplify the spacecraft's orbit of the planet. July 22: Fourth orbit-raising manoeuvre successful The fourth orbit-raising manoeuvre of Chandrayaan-3, or Earth-bound perigree firing, was successfully carried out on July 22. To move the spacecraft closer to the Earth, the manoeuvre was carried out. July 25: Fifth orbit-raising manoeuvre and translunar injection planned A fifth orbit-raising manoeuvre was performed on July 25, and the translunar injection is planned for August 1. The translunar injection will place Chandrayaan-3 on a trajectory to the moon. August 1: Chandrayaan-3 inserted into translunar orbit Chandrayaan-3 was successfully inserted into the translunar orbit on August 1. The spaceship Chandrayaan 3 is now travelling toward the moon. August 5: Chandrayaan-3 inserted into lunar orbit Chandrayaan-3 was successfully inserted into lunar orbit on August 5. The spacecraft is now orbiting the moon in a round pattern. August 6-16: Orbit gradually reduced Chandrayaan-3's orbit is being gradually reduced from 170 km x 4313 km around the moon to 153 km x 163 km. The spacecraft will be able to approach the moons surface closer as a result. August 17: Lander module separated from propulsion module The lander module of Chandrayaan-3 was successfully separated from the propulsion module on August 17. The lander module is now on its own and will soon begin its descent to the moon's surface. August 18: Deboosting of lander module planned The first deboosting of Chandrayaan-3's lander module is planned for August 18. This will reduce the landers orbit and bring it closer to the moon's surface. August 19: Second deboosting of lander module conducted The second and final deboosting of Chandrayaan-3's lander module is conducted on August 19. This reduces the lander's orbit to 25 km x 134 km. August 20: Soft landing of Chandrayaan-3 scheduled The highly anticipated soft landing of Chandrayaan-3 is scheduled for Wednesday at 6.04 pm. The Indian Space Research Organisation ISRO has also announced that a live telecast is planned for the event that starts at 5.20 pm IST August 27: Soft landing backup date If any factors appear to be unfavourable, then the soft landing of Chandrayaan-3 will be postponed to August 27, according to an ISRO scientist.

Introduction to Chadrayaan-3 India’ Third mission to the Moon
India is set to make history on August 22, 2023, when it attempts to soft land its Chandrayaan-3 spacecraft on the moon. The mission led by the Indian Space Research Organisation ISRO is the countrys third lunar mission and its first attempt to soft land a spacecraft on the moon’s south pole.
Chandrayaan-3: A Brief Overview
Chandrayaan 3, Chandra means the moon and yan means a vehicle in the Indian language, is a robotic spacecraft that consists of a lander a rover and an orbiter. The lander carrys the rover to the moons surface while the orbiter will remain in orbit around the moon to provide communication and navigation support. The rover will get around on the surface of the moon and get important data about its geology composition and such.
The Lander
The lander is the most critical part of the Chandrayaan 3 mission. It is in charge of transporting the rover to the moon’s surface and making sure it lands securely. To help in navigating the moons surface and atmosphere the lander was furnished with a broad variety of sensors and technology. It has a landing system as well that allows for soft touch with the moon’s surface.

The Rover
The rover a relatively small vehicle with six wheels will be used to explore the moon s surface. Using a range of tools on its own it has the capability to investigate the geology and composition of the moon. The rover will collect some samples as required from the surface of the moon and use them for further evaluation.
The Orbiter
To assist the lander and the rover with communication and navigation the orbiter will continue to circle the moon. The atmosphere and surface of the moon will also be examined using it. A high resolution camera, a spectrometer, and a radar altimeter are among the sensors and pieces of equipment that the orbiter contains.
The Missions Goals
The Chandrayaan 3 missions major objective is to be successful in softly landing a spacecraft on the south pole of the moon. The overall aim of the mission is to get samples as required for researching the geology and composition of the moons surface.
The Missions Significance
For India space program the Chandrayaan 3 mission represents an important turning point. It is the third mission to the moon by the nation and its first effort to gently land a spacecraft on the south pole of the moon. India will immensely benefit from the trip by learning more about the moon and its resources and will willingly share it with the rest of the world. A new generation of Indian scientists and engineers will be motivated by it as well.
