The vital stage of the Chandrayaan 3 mission will be reached in 5 days with a gentle landing attempt. The Vikram Lander Module has finished the deboosting process.
The most crucial part of the Chandrayaan 3 mission is currently underway with only 5 days until the soft landing attempt. The Vikram Lander Module of Chandrayaan 3 successfully executed a ‘deboosting’ operation on Friday, reducing its orbit to 113 km x 157 km. The second deorbit motion is slated for Sunday at roughly 2 am.
The significant event, according to Mylswamy Annadurai, a former ISRO scientist and recipient of the Padma Shri award, was the firing of the Vikram lander’s 4800 Newton thrusters, which propelled it in two steps to a lower orbit and into a 30-kilometer orbit.
He added that the module’s position needed to be accurately determined. So from that point on, how should one move, fire with push, fire in what direction, and lower velocity in both the horizontal and vertical directions? “And while doing so, it must ensure that it is following the right course. There will therefore be already-loaded images of the lunar surface. Check it against it and try to pinpoint the location of where it should land, Annadurai told ANI.

Complete timetable for the Chandrayaan-3 mission:
The whole Chandrayaan 3 mission’s history up to this point, as well as all future developments, is documented in the timeline below:
- July 6: ISRO announces the July 14 launch date for Mission Chandrayaan-3 from the second launch pad at Sriharikota.
- On July 7 Successful vehicle electrical testing were finished
- July 11: A thorough 24-hour “Launch Rehearsal” that replicated the whole launch procedure comes to an end.
- On July 14, the LVM3 M4 launcher places Chandrayaan-3 in its intended orbit.
- July 15: A 41762 km x 173 km orbit was successfully raised in the first orbit-raising manoeuvre.
- On July 17, Chandrayaan-3 is put into an orbit of 41603 km x 226 km by a second orbit-raising manoeuvre.
- July 22: The fourth orbit-raising manoeuvre places the spacecraft in an orbit of 71351 km by 233 km.
- On July 25, another orbit-raising manoeuvre was accomplished.
- August 1: Chandrayaan-3 entered a 288 by 369328 km translunar orbit.
- August 5: Successful insertion of the moon into orbit (164 x 18074 kilometres).
- On August 6 Lunar orbit reduced to 170 km x 4,313 km
- On August 9, the Indian Space Research Organisation (ISRO) cautiously lowers the spacecraft’s orbital route. It has accomplished a 174 km by 1437 km lunar orbit.
- On August 14, Chandrayaan-3 makes another controlled approach to the moon’s surface, putting it in an orbit of 150 km by 177 km.
- August 16: On its fifth and final Moon-bound manoeuvre, the Indian spacecraft places itself in a nearly circular orbit around the moon at a distance of 163*153 kilometres.
- August 17: The landing module, which includes the Pragyan rover and the Vikram lander, detaches from its propulsion system.
- On August 18, Chandrayaan 3 successfully completed a ‘deboosting’ procedure that made its orbit smaller, at 113 km by 157 km.
- On August 20, the Chandrayaan-3 will make its final orbital adjustment by bringing the distance between the moon’s farthest and closest points, respectively, down to about 100*30 km.
- August 23: If all goes according to plan, a lunar touchdown attempt is scheduled for 5:47 p.m., during which the spacecraft will travel the final 30 km.
The moon must be reached at dawn in order for the mission to be successful since after 14 days on Earth, when night falls on the moon, the temperature will drop beyond the rover’s safe operating range. In the opposite scenario, ISRO might move the landing date to the following September time frame.
The primary goal of the Chandrayaan 3 mission is to conduct experiments on the lunar surface for one lunar day, or 14 days on Earth.
