Chandrayaan-2 lander Vikram, rover Pragyaan separate from orbiter, begin journey to Moon

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 manoeuvre is scheduled tomorrow (September 03, 2019) between 0845-0945 hrs IST

Pragyaan and Vikram are finally on their way to the Moon. After a journey of around a month and a half, Chandrayaan-2 is just six days away from achieving the unachieved – landing a rover on near the south pole of the Moon, a feat unaccomplished by any other country.

Praygyaan is Chandrayaan-2’s six-wheeled rover that is currently housed in the Vikram lander. The lander and the rover successfully broke from the Chandrayaan-2 orbiter Monday afternoon and began their own journey to the Moon. The orbiter will continue revolving around the Moon for the next year.

Over the next few days, the lander Vikram will perform two manoeuvres to bring itself closer and closer to the Moon. By early September 4 morning, Vikram will get into an orbit that will see it fly over the Moon at a height of 36 kilometres at the orbit’s closest point and 110 kilometres at the farthest.

On September 7, the Vikram lander will begin a 15-minute powered descent, which for the Indian Space Research Organisation will be “15 minutes of terror”, to the lunar south pole. With the September 7 landing, India will become only the fourth country in the world to land a rover on the Moon and the only nation to do so near the lunar south pole.



Chandrayaan-2 update: Second de-orbiting maneuver

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
