The Chandrayaan-2 lunar orbiter/lander/rover mission has successfully entered Lunar Transfer Trajectory.

The final orbit raising maneuver of the Chandrayaan-2 spacecraft was carried out August 14, 2019 at 02:21 am IST.

During this maneuver, the spacecraft’s liquid engine was fired for about 1,203 seconds. With this burn, Chandrayaan-2 entered the Lunar Transfer Trajectory.

Spacecraft health

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 the Indian Space Research Organization’s (ISRO) 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 a GSLV MkIII-M1 launcher, all systems onboard Chandrayaan-2 spacecraft are performing normally, reports ISRO.

Lunar orbit

Chandrayaan-2 will approach the Moon 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 have the spacecraft enter into its final orbit passing over the lunar poles at a distance of about (62 miles (100 kilometers) from the Moon’s surface.

A tentative plan for future operation after Trans Lunar Injection has the spacecraft placed in a roughly 71 x 80 mile (114 x 128 kilometer) orbit at the Moon.




Subsequently, the mission’s Vikram lander will separate from the orbiter on September 2, 2019. Two orbit maneuvers will be performed on the lander before the initiation of a powered descent to make a soft landing on the lunar surface on September 7, 2019, touching down near the Moon’s south pole.
