Jiang Yao's father, Jiang Yongchang, although he only appeared briefly in the first episode of "Asking the Heavens", he left a deep impression on me.
He is the commander of the Launch and Aiming Work of the Changsan B Rocket and the most reliable colleague in the eyes of Li Difeng, chief designer of the general office of the Aerospace Research Institute.
In the eyes of Fang Xiaotian, who was even more unruly, the most rigorous aerospace predecessor he had ever seen in his life was still the kind that did not have one of them.
It is such a person, an astronaut who has bowed down to China's aerospace industry, and finally had no chance to see Chang Sanyi successfully ascend to heaven.
Before Jiang Yongchang finally left the aiming room, the look of affection and reluctance seemed to indicate that he would say goodbye to the instruments and equipment here forever.
And the "toy" he fiddled with last became the last device he touched before he died.
I wonder if his daughter Jiang Yao has a chance to find this device as a souvenir?
Speaking of this equipment, he has a very professional name called "total station", the full name is "full-stop electronic speed gauge".
It is a modern optical and electronic measuring instrument that integrates a theodolite, an electronic rangefinder and a computer system.
It is called a "total station" because it can be done simultaneously at one station: horizontal angle, vertical angle, distance, elevation difference and many other measurement work.
The total station used by Jiang Yongchang in the play belongs to the old-fashioned model that requires manual operation of the reflective prism.
This may be used as one of the indirect reasons for the eventual death of Jiang Yongchang and his colleagues.
Because some modern high-end total stations can already achieve the degree of automation of full remote control.
This not only eliminates the precision problem of manual operation, but also allows technicians to stay away from dangerous working environments.
The total station operated by Jiang Yongchang in "Asking the Sky" is the "Southern Total Station NTS-310" produced by "Southern Surveying and Mapping".
The company, founded in 1998, was actually officially established in the second year after the failed launch of the Changsan B.
Although this time difference may be due to the relationship between national self-confidence and the like, it is undeniable that China's space industry is indeed very difficult and difficult.
China's space industry can be traced back to 1956.
In that year, the "Fifth Research Institute of the Ministry of National Defense" was officially established, which is the predecessor of the current "National Space Agency".
In that era when everything had to be on its own, the era that today we call "two bombs and one star".
No one wants to send us these high-tech techniques, and everything has to be done from scratch by ourselves.
After more than 50 years of development and efforts, today we have successfully joined the ranks of space powers.
From the first artificial satellite to the Beidou navigation system into commercial applications.
From the lift-off of the first launch vehicle to the successful return of the first completed manned aircraft.
From Tiangong-1 to Chang'e Moon, from Tianwen-1 orbiting Mars to Zhu Rong's successful landing on Mars.
For 65 years, generations of astronauts have been chasing our space dreams.
Today, they still have more ambitious dreams and goals.
Under the leadership of Jiang Yongchang, Li Difeng, Zhong Xu, and other aerospace experts of the older generation, Fang Xiaotian, Gu Nan, Yang Zhe, Jiang Yao, Qin Manwen, and Yue Tiantian, these aerospace scientists, will continue to climb the peak of science.
Not only have we caught up with and surpassed other advanced countries in the world, but we have also set our own lofty goals.
In the coming days, they will work to build a space station that can carry people for a long time.
Efforts should be made to complete the manned landing on the lunar surface, strive to complete the construction of a lunar manned base, and complete the long-term goals such as unmanned orbit of Mars.
Perhaps the name "Ask the Sky" is looking to the sky for answers, but today's astronauts are already exploring the deeper universe.
Thanks to their tireless efforts, perhaps in the near future, the interstellar travel of ordinary people will no longer be just the plot of the movie.
