If the Chandrayaan 3 mission is carried out successfully by the Indian Space Research Organisation (ISRO), India will join a select group of just three other nations that have accomplished a soft landing on the Moon—the United States, the former Soviet Union, and most recently, China. Before landing on the Moon successfully, both the US and the USSR suffered multiple spacecraft accidents. With the Chang’e-3 mission in 2013, China stands out as the only nation to achieve success in its first attempt.
There are a number of crucial tasks that Chandrayaan 3 must complete, including earthbound maneuvers, entry into the lunar orbit, lander separation, a sequence of deboost maneuvers, and a power descent phase for a smooth landing. The Chandrayaan-3 spacecraft’s project director, P Veeramuthuvel, disclosed this information.
Chandrayaan 3 Live Updates and Location:
23 August – Anticipated to commence on August 23, 2023, at approximately 1745 Hrs. IST, the powered descent marks the next significant phase of this endeavor.
20 August: The second and final deboosting operation was carried out by Chandrayaan-3, resulting in a reduction of the LM orbit to 25 km by 134 km.
August 19, 2023 : The orbit of the moon that the Lander Module is in measures 113 km by 157 km. Plans call for a second de-boosting on August 20, 2023.

August 18: The ‘deboosting’ procedure, which decreased the spacecraft’s orbit to 113 km by 157 km, was successfully accomplished. Deboosting is the process of slowing down to get oneself in an orbit where the Perilune, the point closest to the Moon, is 30 km away and the Apolune, the farthest point, is 100 km away.

August 16 – Chandrayaan-3 has successfully been placed in its intended orbit of 153 km by 163 km thanks to a carefully timed ignition that only needed a short amount of time to complete. The maneuvers to reach the moon have now been completed. The emphasis now is on preparing the Lander Module and the Propulsion Module for their unique paths. The next phase will include the strategic separation of the Lander Module from the Propulsion Module on August 17, 2023.

8th August – In a speech with an NGO called Disha Bharat, Chairman of ISRO Dr. S. Somnath confidently asserts that the Chandrayaan-3 mission will succeed even if the sensors or the engine malfunction. If the propulsion system is strong, Vikram will still make a smooth landing even if everything else fails, including all sensors ceasing to function.
6th August – By firing its engines backwards, the spacecraft successfully carried out a scheduled orbit lowering maneuver. As a result, with an orbit range of 170 km x 4313 km, it has now gotten closer to the Moon’s surface. On August 9, 2023, between 13:00 and 14:00 Hrs. IST, another operation will be carried out to further lower its orbit. This will be the next stage in the procedure.

5th August – Chandrayaan-3 entered the lunar orbit smoothly, precisely reaching the targeted orbital parameters of 164 by 18074 kilometers. At the Perilune, a deft movement was carried out under the direction of the Mission Operations Complex (MOX) at ISTRAC, Bengaluru. Orbit reduction, a crucial stage in the mission strategy, is the next item on the schedule. This event is scheduled to occur on August 6, 2023, about 23:00 Indian Standard Time (IST).

26th July – The TransLunar Injection (TLI), which is expected to take place on August 1, 2023, between 00:00 and 1:00 IST, is planned. The spacecraft’s voyage to the Moon will officially begin when the planned TLI launches it there.
25 July – On July 25, between 2:00 and 3:30 IST, Chandrayaan-3 successfully carried out its fifth and final orbit-raising operation to bring the spacecraft closer to the Earth. The spacecraft is projected to enter an orbit measuring 127,609 km by 236 km once it reaches its destination. On the basis of additional measurements, the attained orbit will be confirmed. From the ISRO Telemetry, Tracking and Command Network (ISTRAC), the maneuver was carried out.

14 July – The triumphant conclusion of the third orbit-raising manoeuvre, carried out between 2:00 and 3:30 PM IST on Tuesday, July 18, was formally confirmed by ISRO. Currently, the spacecraft orbits the Earth at a distance of 51,400 kilometers from its center and 228 kilometers at its furthest point. On Thursday, July 20, between 2 and 3 IST, the following fire event is scheduled.

Following the successful insertion of Chandrayaan-3 into an elliptical lunar orbit the day before, ISRO completed the lunar maneuver on Sunday. The spacecraft’s height at apolune, which represents its closest point to the moon, was effectively lowered during this procedure from 18,074 km to 4,313 km.
Chandrayaan 3 Position
ISRO validated Chandrayaan’s updated orbital parameters as of July 25. The spacecraft will be positioned in its most recent orbit at a distance from the Earth that ranges from 233 kilometers at its closest to 71,351 kilometers at its farthest.
Chandrayaan 3 Status
The thorough reports from ISRO scientists contain crucial information on the rover’s planned Moon landing. As anticipated, the vehicle will be stationed near the Moon’s unexplored South Pole, where it will carry out research on water, ice, and minerals. India stands to gain significantly from this because the South Pole is still a vastly understudied area with a lot of scientific potential.
On July 14 or later, the Indian Space Research Organization (ISRO) intends to make public the outcomes of the successful Moon landing, along with in-depth assessments. The mission’s specifics, including analytical data, will be made public, allowing anybody to participate in this amazing scientific endeavor.
Trans Lunar Injection: What is it?
Trans Lunar Injection (TLI) is a vital maneuver used by rockets or spacecraft to exit Earth’s orbit and reach the Moon. It is a crucial component of lunar missions and is normally carried out once the launch vehicle reaches low Earth orbit (LEO). Trans Lunar Injection is used to provide the spacecraft with the necessary velocity and trajectory so that it can leave Earth’s gravitational field and transition into a trajectory that will intercept the Moon. TLI basically entails increasing the spacecraft’s speed and energy in order to enter a trans-lunar trajectory.
The spacecraft’s propulsion system is ignited during a Trans Lunar Injection at a precise point and with the right amount of thrust to produce the intended trajectory. This burn’s timing and precision are very important because if the spacecraft doesn’t reach the right velocity or angle, it may miss the Moon or fail to enter a stable lunar orbit. The spaceship begins a trajectory that will take it towards the Moon after the Trans Lunar Injection burn is finished. Additional trajectory tweaks and burns may be required along the way to perfect the course and guarantee a successful lunar landing.
