The Indian Space Research Organisation (Isro) on Wednesday successfully conducted final orbit raising manoeuvre of spacecraft. It was carried out at 02:21 am IST.

With this, entered the Lunar Transfer Trajectory.

During this maneuver, the spacecraft's liquid engine was fired for about 1203 seconds. Earlier, the spacecraft's orbit was progressively increased five times during July 23 to August 6, 2019.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.

Since its launch on July 22, 2019 by GSLV MkIII-M1 vehicle, all systems onboard spacecraft are performing normal, said officials.

Chandrayaan-2 will approach on August 20, 2019 and the spacecraft's liquid engine will be fired again to insert the spacecraft into a lunar orbit. Following this, there will be further four orbit maneuvers to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface.

Subsequently, Vikram lander will separate from the orbiter on September 2, 2019. Two orbit maneuvers will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface on September 7, 2019, said

Tentative plan for future operation after Trans Lunar Injection are as follows,
