Having successfully entered the lunar orbit on Tuesday, Chandrayaan-2 is all set to for Moon landing at 1.55am on September 7, as per Isro's current estimates, the space agency's chairman K Sivan said.

After four weeks of interstellar travel, the spacecraft completed its Lunar Orbit Insertion (LOI) as planned, the Indian Space Research Organisation (ISRO) said in a statement.

"The duration of manoeuvre was 1,738 seconds".

Chandrayaan-2 successfully entered into the orbit of the Moon today. The orbit achieved is 114 km x 18072 km.

After the spacecraft enters the moon's orbit, Isro would perform four more maneuvers to place it into the desired orbit, which is 100 kms from the lunar surface.

Subsequently, the lander will separate from the Orbiter and enter into a 100 km X 30 km orbit around the Moon. Two orbit maneuvers will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface on September 7.

The Mission Operations Complex at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru is continuously monitoring "the health of the spacecraft".

Hotline Miami Collection Is Out On Nintendo Switch Today
Past grudges aside, we have some great indie titles coming to the Switch this year, and we couldn't be happier about it. It's a good day for PC Indies making the jump: Superhot and The Hotline Miami Collection make the jump to Switch today .

The next Lunar bound manoeuvre is scheduled on August 21. "From September 2, it will all be done on Lander systems", Sivan said.

The Lander will separate from the Orbiter and soft land at the predetermined site close to the lunar South Pole.

He also said the Gaganyaan, India's human space mission, is also in the process of realisation.

It is after almost a decade that India would reach the moon, since it's historic first mission launched in October 2008. This would take almost four hours, as the rover will move at a speed of 1 cm per minute. Further, the Rover will roll out for carrying out scientific experiments on the lunar surface.

An unmanned spacecraft India launched last month has begun orbiting the moon before it lands on the far side to search for water. Chandrayaan-2 carries as many as 13 payloads and would build on the experiments conducted by its first mission. This is where the Orbiter would carry its year-long journey. This allowed the spacecraft to come under the influence of the moon's orbit.

Chandrayaan-2 lifted off from the Satish Dhawan centre in Sriharikota, Andhra Pradesh on July 22.

If the mission becomes successful India will be the fourth nation - the other three are Russian Federation, the United States and China - to land a spacecraft on the Moon.
