What will happen tonight, understand the whole process
It is already decided that the process of changing the path of the vehicle will start about 5-6 hours before the thrusters are fired. Along with helping in changing the direction, the velocity of the vehicle will be increased by the thrusters. Later on, the velocity of Chandrayaan-3 is expected to increase by 0.5 km per second at perigee. On an average, the vehicle will take 51 hours to cover a distance of 1.2 lakh km. Although the average distance between the Earth and the Moon is 3.8 lakh km, but the actual distance can change depending on the position of the Earth and the Moon on a given day.
This distance can be between 3.6 lakh km to 4 lakh km. Reaching the lunar orbit is a part of the mission. ISRO has already sent Chandrayaan-1 satellite there in 2008 and Chandrayaan-2 in 2019. This time Chandrayaan-3 is going to land on the moon. Crash landing happened last time.
After reaching the moon’s orbit, ISRO will have to do many maneuvers. The landing module will be separated by taking the spacecraft to an altitude of 100 km. That date will be August 17 and on August 23, India’s spacecraft will proceed to kiss the moon.
