Chandraayan-2, now orbiting the moon, has performed the third lunar-bound orbit manoeuvre for the spacecraft, ISRO said on Wednesday.

The Indian Space Research Organisation (ISRO) said that the spacecraft's manoeuvre began at 6.18 p.m., using its onboard propulsion system for 1,155 seconds.

It helped Chandrayaan-2 to reach an orbit which is 124 kilometres at the closest point and 164 kilometres at the farthest.

The next lunar-bound orbit manoeuvre is scheduled on September 1, between 6 to 7 p.m. Chandrayaan-2 had entered the lunar orbit on August 20 after a 29-minute operation guided the spacecraft into a 114kmX18,072km orbit around Moon. The fourth manoeuvre today has placed the spacecraft on a circular path that passes over the lunar poles at a distance of about 100 km from the surface. Next major milestone will be the lander module separation, which, Isro has announced, will be on September 2.

The 124 x 164 km circular orbit that Chandrayaan 2 is in is close enough for the Vikram lander, now bound to the orbiter in a "composite", to separate and attempt a landing. At 1.40am on September 7, the powered descent will start, and at about 1.55am, the lander will make the touchdown.

The mission has been carried out by the scientists and engineers of the national space agency ISRO this evening.
