With the Chandrayaan 2 entering the lunar orbit on Tuesday, India's second mission to moon achieved the "biggest milestone", second only to the 15 minutes of suspense the scientists will experience on September 7 when the lander-rover starts its decent to the moon. "Lunar Orbit Insertion (LOI) maneuver was completed successfully today at 9:02 am as planned.With this, Chandrayaan-2 was successfully inserted into a Lunar orbit", Indian Space Research Organisation (ISRO) said. The process of setting down Chandrayaan 2 on the Moon is very complex since it blasted off at a velocity of 39,240 kilometres per hour, which is nearly 30 times the speed at which sound travels through air.

Following this, there will be further four orbit manoeuvres to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from Moon's surface, ISRO has said.

Chandrayaan 2 had entered the Lunar Transfer Trajectory on August 14 after final orbit raising manoeuvre of the spacecraft was successfully carried out. The Bengaluru-headquartered space agency has said subsequently the Vikram lander will separate from the orbiter on September 2.

"Then, it will perform a series of complex braking manoeuvres to soft land in the South Polar region of the Moon on September 7, 2019", ISRO said. All the systems of Chandrayaan-2 are healthy.

ISRO is continuously monitoring the progress of the mission from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Byalalu.

On July 22, the Chandrayaan-2 was injected into an elliptical orbit of 170X45,475 km by India's heavy lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV Mk III) in a text book style.
