The first de-orbiting manoeuvre for Chandrayaan-2 spacecraft, which is expected to land on moon at 1:55 am on September 7, was performed successfully on Tuesday (September 03).

The first manoeuvre began at around 8:50 am as scheduled using the onboard propulsion system. The duration of the maneuver was 4 seconds. The orbit of Vikram lander is 104 km x 128 km. 

Chandrayaan-2 orbiter continues to orbit the Moon in the existing orbit and both the orbiter and lander are healthy.

The next de-orbiting maneuver is scheduled on September 04, 2019 between 3:30-4:30 am.

Earlier, a former NASA astronaut Donald A Thomas said that when India's ambitious lunar mission Chandrayaan 2 will land on the surface of the moon then everyone at America's space agency and people around the world would be watching it.

"Chandrayaan 2 will be the first spacecraft to land near the South pole of the moon and this is where NASA hopes to land astronaut in about five years from now. Not just NASA, but the whole world would be interested in knowing about the moon and the universe by following Chandrayaan-2," he said.

Thomas said while speaking to reporters after attending an event at Park College of Engineering and Technology near Coimbatore in Tamil Nadu.

He explained, "We have landed near the equator of the moon before but never at the South Pole. The South pole is a very special location, we think there is ice in some of the craters that are permanently shadowed."

"If we find ice there then we can have water and from that Oxygen and Hydrogen," he added.

On being asked about the conditions on the moon, the former NASA astronaut said, "The moon is a tough place to live. There is a lot of radiation out there. At day time temperature there could reach 100 degrees Celcius and during night time minus 100 degrees Celcius."

Chandrayaan 2 will be the first Indian expedition to attempt a soft landing on the lunar surface. This mission will make India, the fourth country after the US, Russia, and China to carry out a soft landing on the moon.

After revolving around the earth's orbit for nearly 23 days, the craft began its journey to the moon on August 14.

The mission took off from the Satish Dhawan Space Centre in Sriharikota on July 22.
