New Delhi:

In a significant milestone for India's Moon mission, the Indian space agency ISRO will manoeuvre the spacecraft into the lunar orbit between 8:30 to 9:30 am today.

This is one of the most tricky operations in the mission because if the satellite approaches the Moon at a higher-than-expected velocity it will bounce off it and get lost in deep space. But If it approaches at a slow velocity, the Moon's gravity will pull the Chandrayaan 2 and it might crash into the surface. The process of setting down Chandrayaan 2 on the Moon is very complex since it blasted off at a velocity of 39,240 kilometres per hour, which is almost 30 times the speed at which sound travels through air. ISRO chairman Dr K Sivan said, "One can imagine even a small error can make Chandrayaan 2 miss its rendezvous with the Moon."

India's most ambitious space mission to date, Chandrayaan 2 had lifted off from India's spaceport at Sriharikota in Andhra Pradesh on July 22. The lift-off was successful in its second attempt, a week after it was aborted just under an hour from its launch due to a technical glitch. The mission stands out because of its low cost, with just about Rs. 1,000 crore spent – a much smaller price tag compared to similar missions by other countries.

Here are the LIVE Updates of the India's moon mission Chandrayaan-2:

After nearly 30 days of interstellar travel, India's moonshot Chandrayaan 2 is nearing its target. In a make-or-break effort, the Indian space agency ISRO will manoeuvre the spacecraft into the lunar orbit between 8:30 to 9:30 am on Tuesday.

But If it approaches at a slow velocity, the Moon's gravity will pull the Chandrayaan 2 and it might crash into the surface.
Aug 20, 201906:53 (IST)The former director of the ISRO satellite centre Dr M Annadurai, who was the head of India's first Moon mission Chandrayaan 1, described the complexity of the ongoing operation saying, "It is like a gentleman with a rose in hand proposing to a lady who is dancing at a stunning speed of 3,600 kilometres per hour (almost five times the speed of an airplane), and not next door, but at a distance of 3.84 lakh kilometres away. If the couple have to meet, then the precision and accuracy is of utmost importance."

Aug 20, 201906:53 (IST) The approach velocity has to be just right and the altitude over the Moon rather precise for the operation to go off as planned. Even a small error can kill the mission. With a few hundred kilometres to the Moon, the satellite will be re-oriented and slowed down by just the right amount so that the Moon can capture the spacecraft and bring Chandrayaan 2 in its embrace. After coasting in the lunar orbit for about a fortnight, the big Moon landing is scheduled for September 7.Aug 20, 201906:52 (IST) After nearly 30 days of interstellar travel, India's moonshot Chandrayaan 2 is nearing its target.
