When Chandrayaan-3 will land on Moon?
India's space agency, the Indian Space Research Organisation (ISRO), is preparing for its third mission to the moon with Chandrayaan-3. After months of orbiting the earth, the spacecraft is set to make a soft landing on the lunar surface on August 23, 05:47 P.M. IST.

LVM3-M4-Chandrayaan-3 Mission:
On August 01, 2023:
The orbit-raising maneuver (Earth-bound perigee firing) is performed successfully from ISTRAC/ISRO, Bengaluru. The spacecraft is expected to attain an orbit of 127609 km x 236 km. The achieved orbit will be confirmed after the observations. The next firing, the TransLunar Injection (TLI), is planned for August 1, 2023, between 12 midnight and 1 am IST.
Chandrayaan-3 Mission Objectives:
The Chandrayaan-3 spacecraft includes a propulsion module, lander, and a rover. The main objective of the mission is to safely land the lander on the lunar soil, with the rover deployed to carry out experiments on the lunar surface for one lunar day, equivalent to 14 Earth days. Imaging of the landing site region will be done to identify safe and hazard-free zones.

Spacecraft Details:
The Chandrayaan-3 mission includes a propulsion module weighing 2,148 kg, a lander weighing 1,723.89 kg, and a rover weighing 26 kg. The soft landing is a tricky issue as it involves a series of complex maneuvers consisting of rough and fine braking.
Lunar Transfer Trajectory and Inter-Planetary Maneuver:
The spacecraft initially follows Earth's orbit and is placed in high Earth orbit using the Geosynchronous Satellite Launch Vehicle (GSLV) rocket. It then embarks on a lunar transfer trajectory, which takes it to a predefined point around the moon before making an inter-planetary maneuver, placing it on the trajectory of orbiting around the moon.
Lunar Orbit Insertion (LOI):
Once the spacecraft arrives in the moon's vicinity, the Lunar-Orbit Insertion (LOI) is performed, which is the process of getting the spacecraft into an optimal orbit around the moon, enabling a precise landing.

Soft Landing:
For a successful soft landing, the lander is designed to descend to the moon from a height of about 100 km from the moon's surface. The landing is a delicate process that involves a series of complex maneuvers involving rough and fine braking. The spacecraft's propulsion system is fine-tuned to ensure a low velocity to enable a smooth landing.
In Short:
India's Chandrayaan-3 mission is a significant milestone for its domestic space program, with the mission's success demonstrating India's growing capabilities in space exploration. This blog post has provided you with a detailed overview of the objectives, spacecraft, and complex maneuvers involved in the mission. Stay tuned as the world eagerly awaits the soft landing on August 23.
