Bengaluru: on Tuesday, in a significant milestone for India's Moon mission (ISRO) will fire Chandrayaan 2's liquid engine to insert the spacecraft into a lunar orbit. "It's tomorrow morning (tentatively between 8.30 am and 9.30 am). It's challenging," K Sivan, the Chairman of Indian Space Research Organisation told PTI on Monday. 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 added.

Subsequently, on September 2, the Vikram lander will separate from the orbiter, according to the Bengaluru-headquartered space agency. According to the news agency, PTI, on September 7, two-orbit manoeuvres will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface, ISRO informed. Chandrayaan 2, launched by GSLV MkIII-M1 vehicle on July 22 had entered the Lunar Transfer Trajectory after final orbit raising manoeuvre of the spacecraft was successfully carried out on August 14. The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) in Bengaluru at ISRO Telemetry, Tracking and Command Network (ISTRAC) with support from Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.
