Chandrayaan 2 Enters New Lunar Orbit

Chandrayaan-2 makes another step closer to Moon, enters new lunar orbit

Chandrayaan-2 began an orbit manoeuvre early Wednesday morning to bring itself closer to landing on the Moon.

It was launched from the Satish Dhawan Space Centre in Sriharikota on July 22 this year.


  • Chandrayaan-2 will further perform 2 more such manoeuvres later this week.
  • The lander will separate on September 2 and will land onto the Moon on September 6.
  • Chandrayaan-2 is expected study the presence of water on the Moon.


Chandrayaan-2, which holds a dream of placing a rover on the lunar surface, has lowered its orbit around the Moon. With just few days to go for the D-Day when the lander Vikram will separate from the spacecraft.

The Indian Space Research Organisation successfully began a manoeuvre Wednesday morning, placing Chandrayaan-2 into an elliptical orbit of about 200 km x 1,500 km around the Moon.

The third lunar bound orbit manoeuvre for Chandrayaan-2 was completed successfully at around 9:30 am, putting the spacecraft in an orbit achieved of 179 km x 1412 km. The next lunar bound orbit manoeuvre is scheduled on the coming August 30.

At the closest point of the new orbit, Chandrayaan-2 is 179 kms away from the lunar surface; at the farthest the spacecraft is 1412 kms away from the Moon.

Chandrayaan-2 will perform two more similar manoeuvres later this week and get even closer to the Moon. By the evening of Saturday, September 1, Chandrayaan-2 will be in a near circular orbit of 114 km x 128 km around the Moon.

On September 2, the lander Vikram is expected separate from the Chandrayaan-2 spacecraft and will get into the orbit of its own around the Moon. And then on September 7, Vikram will begin a 15-minute powered descent to land near the lunar south pole. At South Pole it will set free the six-wheeled Pragyaan rover.

The orbiter will revolve around the Moon for around a year, studying the satellite’s outer atmosphere. The rover, on the other hand, will roam in the area near the lunar south pole for around 14 Earth days, carrying out experiments of surface and sub-surface.

Chandrayaan-2 will make India the fourth country to land a rover on the Moon and the only country in the world to perform a ‘soft landing’ in the lunar south pole region.



One of the most important focus areas of the Chandrayaan-2 mission is water content on the Moon. Chandrayaan-2’s predecessor, Chandrayaan-1 made history in the year 2008 when it confirmed the presence of water on the Moon.

It has been found that the Moon’s south polar region has not received sunlight for billions of years, making it a prime area to store water. Over its 14-day mission period, the six-wheeled Pragyaan will conduct numerous experiments to determine the extent to which water is present on the Moon.


The other experiments that Chandrayaan-2 will perform will aim to expand human’s understanding about the origins of the Solar System.
