In 2019, India's Chandrayan 2 can still land the surface of the moon, which is not good to say that it crashed, and India claims a success rate of 99.99%.
This time, the Chandrayaan-3 lunar probe had a major problem due to the spacecraft's fuel exhaustion during the third orbit change, and the lunar probe lost control and became space dust.
Why did the second experience get out of control and the third time?
In the moonship derailment stage, unexpected! A group of Indian scientists actually went to the temple to pray! Weak heart!
Space probes rely on technological accumulation and excellent technical means, if it is useful to go to the temple to pray, the old horse can go to Mars as soon as he worships the starship of Jesus.
Although the Indian Chandrayaan-3 lunar probe failed, on the space track, their level is still far ahead of South Korea and Japan.
It is reported that the "Chandrayan 3" cost about 73 million US dollars (about 520 million yuan).
Somanat, head of India's Chandrayaan-3, said that learning from the past, some changes have also been made to the design of the Chandrayaan-3 mission. Firstly, the expected landing area of Chandrayan-3 expands, and secondly, the lander receives more fuel, so it can travel longer distances to the landing site or alternate landing site if needed. Then, the physical structure of the lander also changed. The central thrusters on the lander have been removed, the number has been reduced from five to four, and the legs have become stronger to ensure it can land at higher speeds.
