"Vikram successfully separated from Chandrayaan-2 orbiter at 1.15pm. The Chandrayaan-2 orbiter continues to orbit the Moon in its existing orbit. The health of the orbiter and lander is being 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," Isro said.
The next maneuver is scheduled between 8:45am and 9:45am on September 3.
The tentative plan for the upcoming Chandrayaan-2 operations is:
Deorbit 1: September 3 at 09:00 - 10:00 IST. The orbit achieved will be 109 km x 120 km Deorbit 2: September 4 at 03:00 - 04:00 IST. The orbit achieved will be 36 km x 110 km Powered Descent: September 7 Vikram Touch Down: September 7 at 01:30 - 02:30 IST
