Four years after its predecessor crashed on the surface of the Moon minutes before landing, Chandrayaan-3’s lander module with its rover on Wednesday will once again attempt to land on the Moon. Moon at 6:04 pm
Around 5:45 p.m., the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC), Bengaluru, will initiate a lander module powered landing.

If all goes according to plan, 19 minutes later at 6:04 pm, the lander will land safely and smoothly on the Moon and make India the fourth country to achieve this feat. USA, Russia and China.
Important Dates in Chandrayaan-3 . Quest
July 14: given task
July 15-25: Manipulation of raising orbit around the earth
August 1-5: Starting from the earth and going to lunar orbit separated from the propulsion module
August 6-16: Maneuver lower orbit around the moon
August 17: The lander separates from the propulsion module
August 23: Started landing at 5:45pm, landed at 6:04pm
The complex energy landing in Chandrayaan-2 was called “15 minutes of terror” by then ISRO President K. Sivan. It can be recalled that Chandrayaan-2’s Vikram lander nearly dodged this “15 minutes of terror”, but it gave up at 2.1 km before hitting the ground and then losing contact with the crews. ground station.

However, with the Chandrayaan-3 mission, ISRO made several changes to make the mission a success, including strengthening the lander’s legs, reducing the number of engines, increasing the amount of propellant, including new sensors among other things.
Earlier this month, ISRO President S. Somanath said that even if all the sensors fail while attempting a soft landing on the lunar surface, the lander could still land as long as the propulsion system works. .
“If all the sensors fail, we can still land as long as the propulsion system works. Even if the two engines failed, we could still land, that’s how the design was done,” he said. Somanath said.

He added that this time they have made all the systems more robust and have changed the instruction design and introduced newer algorithms.
Deploy autonomous vehicles
Hours after ISRO successfully landed a lander on the lunar surface safely and smoothly, it will deploy the rover to conduct in-situ chemical analysis on the lunar surface during the process. move. Landers and rovers with a mission of one Moon day (14 Earth days) have a scientific payload to perform experiments on the lunar surface.

The Chandrayaan-3 mission was launched on July 14 from the Satish Dhawan Space Center in Sriharikota. Since then, Earthward maneuvers, critical trans-lunar injection (TLI), lunar orbital insertion, orbit miniaturization have been performed along with the separation of the propulsion module and lander module.
ISRO on Tuesday said the mission was on schedule, with tests of the system carried out by scientists and engineers. “The mission is on schedule. The systems are being tested regularly. Smooth sailing continues. Combination of mission activities [MOX] is full of energy and excitement!,” ISRO posted on social media platform X on Tuesday.
