On August 23 at approximately 6:04 p.m. (Indian time), Chandrayaan 3 is anticipated to touch down on the south pole of the moon.

“These are images of the lunar far side area taken by the Lander Hazard Detection and Avoidance Camera (LHDAC),” the statement reads. The ISRO posted on X, formerly known as Twitter, that the camera helps in finding a secure landing place — free of boulders or deep pits — during the fall.

On August 23 at about 6:04 p.m. (Indian time), the Chandrayaan 3 is planned to touch down on the south pole of the moon. The mission’s second and final deboosting operation was completed successfully on Sunday morning.

Journey of Chandrayaan-3 thus far:

July 6: The ISRO announced that the Chandrayaan-3 mission would launch on July 14 from the second launch pad in Sriharikota in Andhra Pradesh.

July 7: The electrical testing on every vehicle were successful.

July 11: ‘Launch Rehearsal’ of 24 hours was accomplished successfully.

July 14: Chandrayaan-3 was sent into its designated orbit by ISRO’s LVM3 M4.

July 15: Bengaluru saw the success of the mission’s first orbit-raising maneuver. The satellite arrived at an orbit measuring 41762 km by 173 km.

July 17: Chandrayaan-3 was put into a 41603 km x 226 km orbit by the second orbit-raising maneuver.

July 22: The fourth maneuver, Earth-bound perigee firing, successfully raised the orbit of the spacecraft to 71351 km by 233 km.

July 25: A second orbit-raising maneuver was completed successfully.

August 1: A key milestone was reached when Chandrayaan-3 entered a 288 km x 369328 km orbit around the moon.

August 5: At 164 km x 18074 km, the spacecraft inserted itself into the lunar orbit.

August 6: The spacecraft’s orbit around the Moon was decreased to 170 km x 4,313 km.

August 9: The spacecraft was lowered to 174 km x 1437 km with another maneuver.

August 14: The mission entered the 151 km by 179 km orbit circularization phase.

August 16: After the firing, the spacecraft moved into its 153 by 163 kilometre orbit.

August 17: The landing module’s propulsion system was cut off, releasing the Vikram lander and Pragyan rover.

August 18: The ‘deboosting’ procedure, which made the spacecraft’s orbit smaller to 113 km by 157 km, was successfully completed. Deboosting is the process of slowing down to get oneself in an orbit with a Perilune (closest point to the Moon) of 30 km and an Apolune (farthest point from the Moon) of 100 km.

August 20: 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 23: The spaceship will touch down on the lunar surface if all goes according to plan and expectations – ISRO
