As the moon provides the best linkage to Earth’s early history, hence, it is the closest cosmic body at which space discovery can be attempted and documented. For the first time since Chandrayaan-2 that was launched on July 22, Vikram, the lander, underwent its first maneuver around the Moon. 

ISRO has successfully completed the first de-orbiting maneuver at 8.50 am Tuesday, using the propulsion systems on Vikram for the first time. All these days all operations were carried out by systems on the orbiter, from which Vikram, carrying the Pragyan (rover) inside it, that separated from on Monday.

In this regard, the Indian Space Research Center (ISRO) said that "The duration of the maneuver was 4 seconds. The orbit of Vikram is 104kmX128 km, the Chandrayaan-2 orbiter continues to orbit Moon in the existing orbit and both the orbiter and lander are healthy".

Following this, the next de-orbiting maneuver is scheduled on September 04 between 3-30am and 4-30am. According to sources, the landing module (Vikram and Pragyan) had successfully separated from the orbiter at 1.15pm Monday, September 02, propelling the mission of Chandrayaan-2 into its last and most crucial place: the moon landing.

According to sources, after the separation, the ISRO chairman K Sivan said, "The operation was great in the sense that we were able to separate the lander and rover from the orbiter—It is the first time in the history of ISRO that we've separated two modules in space. This was very critical and we did it very meticulously," 

He further said that Vikram is expected to touchdown on the lunar surface between 1-30am and 2-30am on September 07. The ISRO had announced that it would be at 1-55am. We are looking at starting the powered descent at 1-40am or 1-45am. The landing must happen 15 minutes after that only.
