Sriharkota: After nearly 30 days of space travel, the Indian space probe Chandrayaan 2 managed to go into lunar orbit on Tuesday. This was one of the most delicate operations of the mission.

A higher approach speed than expected would have bounced the spacecraft in space, while a slow approach would have brought the gravity of the moon to pull Chandrayaan 2 and to the Crush on the lunar surface.

The speed of approach had to be fair and the altitude on the Moon rather accurate. Even a small mistake would have killed the mission.

"Our heart has almost stopped for 30 minutes until the work is done … Three more maneuvers must be completed The next day is around 1 pm The big event will take place on September 2nd, when the LG will be separated, "visibly excited ISRO chairman, K Sivan, told reporters.

"Following this, a series of maneuvers in orbit will be performed on the Chandrayaan 2 spacecraft to allow it to enter its final orbit by flying over the lunar poles at a distance of about 100 km from the moon's surface." , said the Indian space research organization post on their website today.

"Subsequently, the landing gear will separate from the orbiter and enter an orbit around the 100 km by 30 km moon and then perform a series of complex braking maneuvers on soft ground in the polar region south of the moon on September 7, 2019, "said ISRO in their message.

The process of landing Chandrayaan 2 on the Moon is very complex because it took off at a speed of 39 240 km / h, almost 30 times the speed at which the sound moves in the air.

The former Director of the ISRO Satellite Center, Mr. Annadurai, who was leading the first Indian Chandrayaan 1 lunar mission, described the complexity of the operation as follows: "It's like a gentleman with a rose in his hand who offers a lady dancing in front of an amazing speed of 3,600 kilometers at the time (almost five times the speed of a plane), and not next, but at a distance of 3.84 km / h. If the couple is to meet, accuracy and accuracy are of paramount importance. "

Chandrayaan 2, India's most ambitious space mission to date, had taken off from the Sriharikota Spaceport in Andhra Pradesh on 22 July. The takeoff was successful on his second attempt, a week after having interrupted it a little less than an hour after its launch. to a technical problem.

The mission stands out for its low cost, with hardly more than Rs. 1,000 crores spent – a price much lower than similar missions in other countries.
