Chandrayaan 3 successfully completed on August 1, i.e. today it completed its translunar injection (TLI). After remaining in Earth’s orbit for two weeks, the spacecraft will now begin its journey toward the Moon. Chandrayaan 3 is scheduled to enter the moon’s orbit 4 days later on August 5, 2023.
Meanwhile, for the next 18 days, Chandrayaan 3 will orbit the moon, and when the integrated spacecraft enters the moon’s orbital space, it will start to slowly descend orbit before obtaining a circular orbit of around 100 x 100 km. . The lander and rover are scheduled to touch down on the moon on August 23 after a final descent to this distance, if all goes to plan.
Instead of simply aiming for the Moon, both the current and past Indian missions have cleverly taken advantage of Earth’s gravity to boost their speed. They achieved this by circling the Earth, gradually increasing its orbit and gaining the necessary momentum.
The integrated spacecraft will land at 69.36°S and 32.34°E at 5:47 pm, and the location is very close to the south pole of the moon. This region was carefully selected for some compelling reasons. In particular, numerous craters in this area remain perpetually in shadow, making it a potential storehouse for valuable resources such as water ice and precious minerals.
ISRO tweeted about the successful TLI:
“Chandrayaan-3 completes its orbit around the Earth and heads towards the Moon. Following a successful perigee firing performed at ISTRAC, ISRO has injected the spacecraft into translunar orbit. When it reaches the Moon, Lunar Orbit Insertion (LOI) is planned for August 5, 2023..”

The separation of the two modules, which consist of a propulsion module and a lander module, will take place on August 17. Before the power down phase, the soft landing on the moon will also include a series of destimulation procedures.
For the mission’s ‘Vikram’ lander to properly use available sunlight and power its science payloads, sensors and communication equipment, it must land on the Moon’s surface at the beginning of the lunar day.
The lander will collect solar energy using solar panels and store it in batteries, allowing it to run its many instruments at night. It will also collect data and communicate with Earth in real time. Scheduling the landing at the beginning of Lunar Day is crucial to the successful execution of mission objectives.
