In a major milestone for India's Moon mission, the Chandrayaan-2 spacecraft successfully entered the lunar orbit on Tuesday.
Addressing a press conference, ISRO Chief K Sivan said that Chandrayaan-2 mission crossed a major milestone today after its precise lunar orbit insertion maneuver was carried out at 9 am for about 30 minutes and Chandrayaan 2 was precisely inserted in the defined orbit.
The next major event will happen on September 2 when the lander will be separated from the orbiter, he said.
"On 3rd September we will have a small maneuver for about 3 seconds to ensure that the systems of the lander are running normally."
Lunar Orbit Insertion (LOI) maneuver was completed successfully at 09:02 hours as planned, using the onboard propulsion system, the Bengaluru headquartered space agency said in a statement.
"The duration of manoeuvre was 1,738 seconds. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit," ISRO said.
Following this, a series of orbit manoeuvres 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 Moons surface, it said.
Subsequently, the lander will separate from the Orbiter and enter into a 100 km X 30 km orbit around the Moon.
Then, it will perform a series of complex braking manoeuvres to soft-land in the South polar region of the Moon on September seven, ISRO stated.
The health of the spacecraft is being continuously monitored 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 Bylalu, near Bengaluru.
The next Lunar bound orbit manoeuvre is scheduled on Wednesday between 12.30 PM and 1.30 PM, ISRO said.
Chandrayaan-2, launched on July 22 by GSLV MkIII-M1 vehicle, had entered the Lunar Transfer Trajectory on August 14. According to ISRO, Chandrayaan 2 -- India's second lunar expedition -- will shed light on a completely unexplored section of the Moon its South Polar region.
"This mission will help us gain a better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface", the space agency had said.
"While there, we will also explore discoveries made by Chandrayaan 1, such as the presence of water molecules on the Moon and new rock types with unique chemical composition", it was stated.
Chandryaan-2 comprises an Orbiter, Lander (Vikram) and Rover (Pragyaan). The mission life of Orbiter will be one year whereas the mission life of lander (Vikram) and rover (Pragyan) will be one Lunar day which is equal to fourteen earth days.
