India’s moon mission to mark history tomorrow as the Chandrayaan-2 is moving much closer to the Moon and as scheduled by ISRO, the space agency will inject the liquid engine into the lunar orbit of Moon.
ISRO chairman K Sivan said, "It's tomorrow morning (tentatively between 8.30 am and 9.30 am). It's challenging." As the space research agency is to put the spacecraft in an orbit around the Moon on Tuesday, the agency is excited and nervous as it is on its way to create history with the Chandrayaan-2.
With the injection of the liquid engine in the lunar orbit, four more orbit manoeuvres will follow to make the spacecraft enter into its final orbit. The distance of passing over the lunar poles is about 100 km from Moon's surface.
As per ISRO statements, the Vikram lander will separate from the orbiter on September 2. For the final landing, two-orbit maneuvers will be performed on the lander followed by a soft landing on the lunar surface on September 7.
Notably, it was on July 22 when the Chandrayaan-2 was launched and now it and finally entered the Lunar Transfer Trajectory on August 14 after final orbit raising maneuvers of the spacecraft was successfully carried out. Meanwhile, the spacecraft is continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru. In doing this, ISRO has also taken support from the Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.
ISRO states that the mission will help it in gaining a better understanding of the origin and evolution of the Moon for which it will conduct detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface.
It further adds that the agency will also explore the discoveries made by Chandrayaan1. The former spacecraft had discovered the presence of water molecules on the Moon and new rock types with unique chemical composition.
