Launched onboard India’s most powerful rocket, GSLV MK-III, Chandrayaan-2 will collect and send date from the Moon.
22 July 2019:
As the GSLV MK-III entered space, the 1st, 2nd and 3rd stage rockets fired one-by-one then separated from the launcher pushing it into lunar transfer trajectory.
24 July 2019, 2.52 pm:
First earth bound orbit raising manoeuver performed using the spacecraft’s onboard propulsion system for a firing duration of 48 seconds.
Four more manoeuvres raise its orbit and put it on lunar trajectory. On entering the Moon’s sphere of influence, thrusters will slow it down for lunar capture.
384,000 km distance travelled by the lander-rover to reach the Moon’s orbit.

A 6.5-second-long burn brings the lander-rover closer to the surface of the Moon in preparation for a soft landing.
7 September, 1.40 am:
The lander-rover will begin its powered descent. Landing will take place at 1.55 am. The rover will carry out experiments on the Moon for one lunar day (14 Earth days).
The Orbiter
The Chandrayaan-2 Orbiter is capable of communication with Indian Deep Space Network (IDSN) at Byalalu (25 km from Bengaluru) as well as the Vikram lander. The orbiter will be placed in a 100km x 100 km lunar polar orbit for a period of one year.
