India’s ISRO has now inched even closer towards making history, and towards — what Chairman Dr. K Sivan described — as the “15 most terrifying minutes” for Chandrayaan-2. At 9:30 AM today, ISRO commenced the mission critical Lunar Orbit Insertion by firing retro thrusters on Chandrayaan-2. The operation was completed in text-book precision.
The duration of maneuver was 1738 seconds beginning from 0902 hrs IST. With this, Chandrayaan-2 was successfully inserted into a Lunar orbit. The orbit achieved is 114 km x 18072 km.
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.
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. All the systems of Chandrayaan-2 are healthy.
