Fifth Lunar Orbit Maneuver

The final and fifth Lunar bound orbit maneuver for Chandrayaan-2 spacecraft was performed successfully today (September 01, 2019) beginning at 1821 hrs IST as planned, using the onboard propulsion system. The duration of the maneuver was 52 seconds. The orbit achieved is 119 km x 127 km.

All spacecraft parameters are normal.

The next operation is the separation of Vikram Lander from Chandrayaan-2 Orbiter, which is scheduled on September 02, 2019, between 1245 – 1345 hrs (IST). Following this, there will be two deorbit maneuvers of Vikram Lander to prepare for its landing in the south polar region of the moon.

Tentative plan for future operations after today’s maneuver are as follows,

Vikram Lander successfully separates from Orbiter

The Vikram Lander successfully separated from Chandrayaan-2 Orbiter at 1315 Hrs IST today (September02, 2019). The Vikram Lander is currently located in an orbit of 119 km x 127 km. 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. All the systems of Chandrayaan-2 Orbiter and Lander are healthy. The next maneuver is scheduled tomorrow (September 03, 2019) between 0845-0945 hrs IST.

The second de-orbiting maneuver for Chandrayaan-2 spacecraft was performed successfully today (September 04, 2019) beginning at 0342 hrs IST as planned, using the onboard propulsion system. The duration of the maneuver was 9 seconds.

The orbit of Vikram Lander is 35 km x 101 km. Chandrayaan-2 Orbiter continues to orbit the Moon in an orbit of 96 km x 125 km and both the Orbiter and Lander are healthy.

With this maneuver the required orbit for the Vikram Lander to commence it descent towards the surface of the Moon is achieved. The Lander is scheduled to powered descent between 0100 - 0200 hrs IST on September 07, 2019, which is then followed by touch down of Lander between 0130 - 0230 hrs IST

historic? Americans landed on the moon 60 years ago.

we soft landed on the far side of moon with a much much bigger payload than yours.

Good for you. Historic event for us.

India is doing it for the SAME reason why China is Doing it. btw, We did beat you to the Mars... !
