The Indian Space Research Organization (ISRO) on Friday evening claimed to have successfully completed the fourth lunar-bound orbit change for the Chandrayaan-2 spacecraft.

The duration of the manoeuvre was 52 seconds.

The engines on the spacecraft were fired for 1,155 seconds by the end of which Chandrayaan-2 was orbiting the moon at an orbit of 124 km x 164 km.

A total of five manoeuvres are planned to gradually make the lunar craft's oval orbit circular with the desired circular orbit expected after two more orbit reducing operations - on August 30 and September 1.


It was last Tuesday that ISRO successfully placed Chandrayaan 2 into the lunar orbit.

"ISRO has great pleasure in informing that you have been selected to watch the historical Chandrayaan-2 moon landing in the early hours of September 7, 2019 at the ISRO Tracking Centre (ISTRAC), Bengaluru in the presence of Honourable Prime Minister of India Shri Narendra Modi Ji". It will then perform a series of complex braking manoeuvres to soft land in the South polar region of the Moon on 7 September 2019.

The lander carrying the rover is set to make a soft-landing near the lunar South Pole on the seventh of next month.

India's Geosynchronous Satellite tv for pc Launch Car, GSLV MkIII-M1, had efficiently launched the three, 840-kg Chandrayaan-2 spacecraft into the earth's orbit on July 22.


Chandrayaan-2 narrowed its distance from the moon's surface after a crucial manoeuvre yesterday. India will be the first nation to explore the Moon's south pole.

Chandrayaan-2 will be India's first expedition to attempt a soft landing on the lunar surface.

On the science front, the mission aims to further expand the knowledge about the moon through a detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere, leading to a better understanding of the origin and evolution of the moon, the space agency had said.
