Hello everyone, I'm Xiaohao, daily news, pay attention to me!Let's take a look at the content of this issue[Come and see me]
Recently, Bill Nelson, the administrator of the National Aeronautics and Space Administration (NASA), made a speech at a hearing of the Budget Committee of the U.S. House of Representatives, once again pushing the "China space threat theory" to the forefront.

As soon as this remark came out, it immediately caused an uproar among the people present and heated discussions among netizens.
In fact, the far side of the moon is not forever in darkness. Although it always has its back to the Earth and cannot be directly seen by observers on Earth, this does not prevent sunlight from reaching every corner of the far side of the Moon. The rotation period of the Moon is the same as the period of revolution around the Earth, which results in one side of the Moon always facing the Earth and the other side always facing away from the Earth. However, both the front and back sides of the Moon experience a day-night cycle, but we cannot directly observe the sunlight exposure on the far side of the Moon from the Earth.
This common-sense mistake of Nelson undoubtedly exposed his lack of basic knowledge of the moon.
Of course, we can't completely dismiss Nielsen or NASA's contributions to space exploration just because of this statement.
At the same time, we should also note that China's rapid rise in the field of space exploration has become an indisputable fact. China's Chang'e series of probes have successfully achieved a series of major breakthroughs such as soft landing on the moon and sample return, providing new perspectives and data for mankind to understand the moon. China's achievements in space exploration not only demonstrate the country's scientific and technological strength, but also make positive contributions to the development of mankind's space industry.
In the face of China's space exploration achievements, we should look at them with an open and inclusive attitude, rather than blindly smear and suppress them. Space exploration is the common cause of all mankind, and it requires all countries to work together to promote it.
Okay, I'm Xiaohao, that's all for this issue, [come and see me]
