At 4: 30am on 24th, it was an exciting and proud moment for all China people. The Long March V carrier rocket was launched from Wenchang Space Launch Site in Hainan, and Chang 'e V flew to the moon.
As the finale of China's unmanned lunar exploration, Chang 'e-5 has gathered almost all the top technologies of China's space flight at present. It lasted more than 20 days as planned, and the main highlight was "digging" things from the moon.
Experts said that this launch will also be an early preview of China's manned landing on the moon, providing technical verification for manned landing on the moon in 10 years.
Maybe some netizens will say that Americans manned the moon more than 50 years ago, and we have to wait 10 years. Is it really that difficult?
In fact, China and the United States have different routes to the moon, and the technical design and value factors are much more complicated.
Moreover, at that time, the United States and the Soviet Union engaged in a "space race", and the "form" of landing on the moon was greater than the "content", and the cost reached an astonishing $25.5 billion. Some people convert it into present value according to purchasing power, which is equivalent to spending $200 billion.
As we all know, the success of manned landing on the moon depends not only on advanced scientific and technological strength, but also on cultivating a group of astronauts with excellent quality.
It should be said that being selected by the state to carry out space missions is definitely a matter of no honor.
So far, our country has selected two groups of astronauts. On June 65438+1 October1day this year, the selection of the third batch of preparatory astronauts also ended. * * * There are 18 reserve astronauts (including female 1 person), but the final list has not been finalized.
Among them, the first astronauts were Yang Liwei, Jing Haipeng, Fei Longjun, Nie Haisheng, Zhai Zhigang and Liu Boming. Among the second batch of astronauts, only Liu Yang, Wang Yaping and Chen Dong have ever flown.
Assuming that our country really realizes manned landing on the moon in 10, who among these astronauts who have already flown into the sky will want to be selected to participate in this mission?
Carrying out space missions requires the astronauts to be extremely physical and not too old. Jing Haipeng is the astronaut who has flown the most times at present, and he is also the oldest astronaut when performing his mission.
20 16 10 17, 50-year-old Jing Haipeng performed the Shenzhou XI mission and served as the commander.
Now it seems that this age may be the basic "red line" determined by the state.
According to this analysis, most of the first astronauts who have flown were born in the 1960s, and several generals have been promoted. Even now, it is difficult to carry out space missions, not to mention 10 years later.
In the second batch, only Liu Yang, Wang Yaping and Chen Dong have hope.
According to the published data, we find that Liu Yang and Chen Dong were born in 1978, and Wang Yaping was born in 1980.
10 years later, Liu Yang and Chen Dong are 52 years old, while Wang Yaping is just 50 years old. By then, she is likely to perform the miracle of Jing Haipeng flying at an advanced age.
In fact, this is not necessarily true, because many astronauts in their 50s are still serving abroad.
For example, American astronaut john glenn was 77 years old when he went into space in the space shuttle Discovery on June 198+00.
Aerospace is the cause on the spire, and technology is the ladder to climb the spire. By then, no matter who will be the first astronaut to land on the moon in China, it will not be the glory of one person, but the glory of the whole Chinese nation.
