Chandrayaan-3, a probe sent by the Indian Space Research Organization (ISRO) to study the South Pole of the Moon, has achieved a historic feat by landing at its destination without a hitch. Moreover, its rover and lander instruments have fulfilled their responsibilities. They also sent lots of information and pictures.
After the sun’s rays disappeared over the South Pole, the ship’s instruments were neutralized. Now it’s been a week since the sun started shining there again. But the efforts of scientists to revive Pragyan rover and Vikram lander were not successful. Meanwhile, the Chinese scientist’s statement is under discussion.
Ouyang Jiyuan, a prominent Chinese cosmochemist (a scientist who studies the chemical composition and changes in the universe), on Wednesday denied the success of India’s Chandrayaan-3 spacecraft. Jiyuan was the chief scientist during China’s first lunar mission.
Jiyuan asserted that the Indian spacecraft did not land at the Moon’s South Pole, or even near it.
“The landing site of Chandrayaan-3 is not the south pole of the moon, not in the south pole of the moon, nor in the Antarctic polar region,” Jiyuan, a member of the Chinese Academy of Sciences, told the academy’s official Science Times newspaper.

What is Jiyuan’s argument?
He argued for this different perception based on what he considered the moon’s south pole to be like.
The Earth’s South Pole is defined as anything between 66.5 and 90 degrees south. Its frequency axis is at an angle of about 23.5 degrees to the Sun. Jiuan argued that the polar region would be much smaller because the Moon’s inclination is only 1.5 degrees.
While NASA has estimated that the south pole of the Moon may be 80-90 degrees, Jiuan said that it is only between 88.5 and 90 degrees.
Being the fourth country to land a spacecraft on the Moon and the first to land on the South Pole, India has not doubted the achievement of India, including NASA and the European Space Agency. These institutions have praised Indian scientists who have done something that no other country has been able to do. India had made it clear from the beginning that Chandrayaan-3 would land at an approximate latitude of 70 degrees near the Moon.

Hong Kong scientist support to India
Chinese scientist Jiyuan’s argument has been rejected by a scientist from Hong Kong University’s Space Research Laboratory.
“After landing the rover near the South Pole, it will enter the area defined as the South Pole. This is already a big achievement. No pride can be taken away from India for this reason,” scientist Quentin Parker told the South China Morning Post.
