In a significant milestone for India's Moon mission, ISRO fired Chandrayaan 2's liquid engine on Tuesday to successfully insert the spacecraft into a lunar orbit. The Indian space agency ISRO on Tuesday in a tweet said "Lunar Orbit Insertion (LOI) of #Chandrayaan2 manoeuvre was completed successfully today (August 20, 2019). The duration of this operation was 1738 seconds beginning from 0902 hrs IST."

Following this, a series of orbit maneuvers will be performed on Chandrayaan-2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface. Subsequently, the lander will separate from the Orbiter and enters into a 100 km X 30 km orbit around the Moon.  Then, it will perform a series of complex braking maneuvers to soft land in the South polar region of the Moon on September 7, 2019.

ISRO also said that The next Lunar bound orbit maneuver is scheduled tomorrow (August 21, 2019) between 1230-13:30 hrs IST.

Chandrayaan2, which was launched on July 22 by GSLV MkIII-M1 vehicle, had entered the Lunar Transfer Trajectory on August 14 after final orbit raising manoeuvres of the spacecraft was successfully carried out.

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

All the systems and networks of Chandrayaan2 spacecraft are working correctly, ISRO stated August 14.

According to ISRO, Chandrayaan2 (India's second lunar expedition) will through light on a completely unexplored region of the Moon, which is its the South Pole.

"This mission will help us to gain a better understanding about the origin and evolution of the Moon through conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface," the space agency has said.

ISRO followed by saying " We will also explore discoveries made by Chandrayaan1, such as the presence of water molecules on the Moon’s surface and new rock types with unique chemical composition,".
