Today is space with you [Issue 1355]
The "big cauldron" in Guizhou
Recently, a lot of "good dishes" have been stewed.
January 5, 2022
Learned from the Chinese Academy of Sciences
In 2021
Scientists rely on the "Chinese Sky Eye" FAST
A number of important scientific research achievements have been achieved
Continuous discovery of millisecond pulsars;
FAST neutral hydrogen lines measure interstellar magnetic fields
Significant progress has been made;
Obtain samples of the largest rapid radio burst event to date;
For the first time, the complete energy spectrum of the burst rate of fast radio bursts has been revealed
and its bimodal structure;
……
Vice President of the Chinese Academy of Sciences and member of the Party Group
Zhou Qi, an academician of the Chinese Academy of Sciences, said
FAST has become a sharp tool for viewing the sky in the field of medium and low frequency radio astronomy
It has entered a new stage of "more results" and "good results"
Obvious advantages based on ultra-high sensitivity
FAST has become
A celestial instrument in the field of medium and low frequency radio astronomy
The future will be output
More scientific achievements to deepen human understanding of the universe
China Tianyan is proud of these achievements
There is one person who can do a lot
He is
Nan Rendong
To the south there is Rendong
Pursue the dream of the stars
Nan Rendong, the father of the "Chinese Heavenly Eye"
More than twenty cold and hot and cold
More than 8,000 days and nights
He spent nearly a third of his life
In the history of world astronomy
Engrave a new Chinese height
Known as the "Chinese Heavenly Eye"
500 m Aperture Spherical Radio Telescope (FAST)
It is a giant eye for viewing the heavens and a heavy instrument for the country
China Sky Eye was inaugurated on September 25, 2016
On January 11, 2020, it was officially opened for operation through national acceptance
It is currently the world's largest and most sensitive radio telescope
It is reported that FAST has passed the national acceptance since January 2020
Operational efficiency and quality continue to improve
The annual observation time exceeds 5300 hours
In March 2021, FAST officially opened up to the world for sharing
There are already 27 international projects in 14 countries (excluding China).
Obtain approval and initiate scientific observations
"Everybody else has their own big device
We didn't, and I'd love to give it a try. ”
For that sentence
He carried a bamboo pole
Persistently running in the depths of the mountains
Drink muddy water and eat cold dry food
Tread hundreds of nests
"For site selection
Teacher Nan had almost stepped on it at that time
All the depressions there."
He had an original dark beard and hair
It also gradually became white
"He always says that FAST has a lifespan of 30 years
It is equivalent to 110,000 countries investing 110,000 in 1 day of use
If you stop working for one day because of a work error, you will lose 110,000 yuan
This burden has always been on the heart."
FAST consultant Scork said
He named the project FAST
Just hope for this project
Be sure to hurry! A little faster!
Let China explore the universe faster! ”
In 2014, the FAST reflector unit will soon be hoisted
Nan Rendong, who is nearly seventy years old, insists on being the first to go up
Personally conduct the "Flying Man" manned test
This test requires a simple device to lift the person up
Delivered to a 6-meter-high test node dish
There is no place to stay in the high altitude, and the whole process needs to be manually operated
If you are not careful, you may fall down
Coming down from the sky, Nan Rendong's clothes were soaked with sweat
But he found several problems in the experiment
Just when the "Chinese Heavenly Eye" is about to be built
Nam Rendong was diagnosed with lung cancer
However, only 3 months after the operation
He reappeared at the construction site
He never had a moment
I have forgotten my scientific career
September 15, 2017
He left us forever
A year later
There is one more "Nanren East Star" in the sky
Perhaps, he is doing it in a different way
Keep watching
The land he loved all his life
"The senses are peaceful and silent
The beautiful space of the universe is full of its mystery and splendor
Beckons us to step through mediocrity and into the vast expanse of infinity. ”
Many people remember, before leaving this world
Nan Rendong ate word for word
Confess to the starry sky he loved all his life
"72 years of life, like just for FAST"
24 years, from site selection, project approval, feasibility study
To guide the study of various key technologies as well as model tests
Nan Rendong gave his life's energy unreservedly
This "great power heavy weapon"
His eyes were closed
China's "heavenly eyes" have slowly opened
The history of world astronomy was changed by him
Whenever I hear his name
We can always weep with pride
It's not just Nam Ren Dong
Look at the long river of time
One by one, the figures went forward and followed
Again and again science and technology
Behind the innovation breakthrough
It's a generation of scientists
Long-term hard work and perseverance
Hats off to Mr. Nam In-dong!
Hats off to all of them!
