Chandrayaan-2 to Leave Earth Orbit Tomorrow After Trans Lunar Insertion

ISRO has said it will carry out the manoeuvre called Trans Lunar Insertion (TLI) between 3:00am and 04:00am IST.

  India's Chandrayaan-2 satellite is set to move towards the moon after leaving the earth's orbit, with the Indian Space Research Organisation (ISRO) planning to carry out a crucial manoeuvre early on Wednesday.

  The Chandrayaan-2 spacecraft is expected to reach the moon's orbit on August 20 and land on the lunar surface on September 7, according to the ISRO.

  The fifth earth-bound orbit raising manoeuvre for Chandryaan-2 was performed successfully on August 6 using the onboard propulsion system for a firing duration of 1,041 seconds, following which the ISRO had said all the spacecraft parameters were normal.

  A series of orbit manoeuvres was carried out using Chandrayaan-2's onboard propulsion system to raise the spacecraft orbit in steps and then place it in the Lunar Transfer Trajectory to enable the spacecraft to travel to the vicinity of the moon.

  After leaving the earth's orbit and on entering the moon's sphere of influence, the onboard propulsion system of Chandrayaan-2 will be fired to slow down the spacecraft, which will enable it to be captured into a preliminary orbit around the moon, the ISRO said.

  Later, through a set of manoeuvres, the orbit of Chandrayaan-2 around the moon will be circularised at a height of 100 km from the lunar surface.

  Subsequently, the lander will separate from the orbiter and enter into a 100kmx30km orbit around the moon, and then, it will perform a series of "complex braking" manoeuvres to soft land in the south polar region of the moon on September 7.
