The Indian Space Research Organisation (ISRO) on Friday at 2.30pm launched the Chandrayaan-3. The spacecraft blazing fire made its way to the far side of the moon in a follow-up mission to its failed effort nearly four years ago to land a rover softly on the lunar surface. Chandrayaan-3, the word for “moon craft" in Sanskrit, took off from a launch pad in Sriharikota in Odisha with an orbiter, a lander and a rover.
The spacecraft was launched on a GSLV Mark 3 (LVM 3) heavy-lift launch vehicle. The Chandrayaan-3 is set to embark on a journey lasting slightly over a month before landing on the moon’s surface later in August. A successful landing would make India the fourth country — after the United States, the Soviet Union, and China — to achieve the feat.
Chandryaan-3’s path will be similar to that of Chandrayaan-2. It will consist of three stages — Earth orbit manoeuvres, Trans-lunar injection, and Lunar orbit manoeuvres. After the Chandrayaan-3 completes the three stages , the lander separates from the propulsion module, enters an orbit closer to the moon and begins soft-landing.
Chandrayaan-3 will make five orbit manoeuvres around the Earth, each time increasing the distance it swings away from the Earth. Then, after it completes the fifth manoeuvre, it begins to move towards the moon. Similar to the orbit manoeuvres around the Earth, Chandrayaan -3 will orbit the moon four times, each time coming closer. Eventually, it will reach a circular orbit of 100 km x 100 km. AT this point the lander separates from the propulsion module, and alters its orbit so it comes as close as 30 km to the moon.
