Are you satisfied with what you see in the sky today?

Nan Rendong, who devoted his life to the "China Sky Eye"

The last time he met his assistant Jiang Peng

Still thinking about the "Eye of the Sky"

Later I learned that Nan Lao had passed away.

Jiang Peng sent another letter to Nan Lao

“Work report email”:

"Mr.

Will we have a chance to talk again?"

Now what Jiang Peng wants to know most is:

"Is the old man satisfied with what we have done?"

January 5, 2022

From the Chinese Academy of Sciences

2021

Scientists rely on the "China Sky Eye" FAST

A number of important scientific research results have been achieved

Continued discovery of millisecond pulsars;

FAST neutral hydrogen spectrum measures interstellar magnetic field

Significant progress has been made;

Obtained the largest sample of fast radio burst events to date;

Full spectrum of fast radio burst rates revealed for first time

and its bimodal structure;

…

Vice President and Party Committee Member of the Chinese Academy of Sciences

Zhou Qi, an academician of the Chinese Academy of Sciences, said

FAST has become

A powerful tool for sky observation in the field of medium and low frequency radio astronomy

Already entered

A new stage of "producing more results" and "producing better results"

Obvious advantages based on ultra-high sensitivity

FAST has become

A powerful tool for sky observation in the field of medium and low frequency radio astronomy

Will produce in the future

More scientific achievements that deepen humanity’s understanding of the universe

China's Sky Eye: These achievements make us proud

Let everyone's heart

They all shouted a name at the same time:

Nan Rendong

Rendong in the South

Chasing the Star Dream

Nan Rendong, the father of "China's Sky Eye"

More than twenty years of winter and summer

More than 8,000 days and nights

He spent nearly a third of his life

In the history of world astronomy

Carving a new height for China

Known as the "China Sky Eye"

Five-hundred-meter Aperture Spherical Radio Telescope (FAST)

It is a giant eye for observing the sky and a national treasure.

China's Sky Eye was completed and put into use on September 25, 2016

January 11, 2020

Passed national acceptance and officially opened for operation

It is currently the largest and most sensitive radio telescope in the world.

It is reported that

FAST has been in operation since January 2020.

After passing the national acceptance

Continuously improving operational efficiency and quality

More than 5,300 hours of observation per year

March 2021

FAST officially opens to global sharing

There are 14 countries (excluding China)

27 international projects

Obtain approval and start scientific observations

2022

FAST is also considering offering

Open 1% of observation time

“Others have their own big equipment

We don't

I’d like to give it a try.”

For this sentence

He leaned on a bamboo pole

Running persistently in the depths of the mountains

Drink muddy water and eat cold dry food

Traveling through hundreds of places

“For site selection

Teacher Nan had almost visited all

All the depressions there"

His originally black beard and hair

It gradually turned white.

“He always said

FAST has a lifespan of 30 years

This is equivalent to the country spending 110,000 yuan for one day of use.

If you stop using it for one day due to work errors

Loss of 110,000

This burden has always weighed on my heart.”

FAST consultant Scott said

"He named the project FAST

I hope this project

Gotta be quick

Faster

Let China explore the universe faster! "

2014

FAST reflector unit is about to be hoisted

Nan Rendong, who is nearly 70 years old, insisted on being the first

Conduct the manned test of the "Little Flying Man" in person

This experiment requires a simple device to hang a person up

Delivered to the 6-meter-high test node plate

No place to stand in the sky

Manual operation is required throughout the process

A little carelessness

You might fall down.

Come down from the sky

Nan Rendong's clothes were soaked with sweat

But he found several problems in the experiment

Just as the "China Sky Eye" is about to be completed

Nan Rendong was diagnosed with lung cancer

However, only 3 months after the operation

He appeared at the construction site again.

He never had a moment

Forgot about my scientific research career

September 15, 2017

He left us forever

One year later

There is a new "Nan Rendong Star" in the sky

perhaps

He is doing it in another way

Keep watching

This is the land he loved all his life.

"Sensory tranquility and silence

The beautiful universe is full of mystery and splendor.

Calling us to step beyond mediocrity and enter the boundless vastness"

Many people still remember

Before leaving this world

Nan Rendong spoke word by word

Confessing to the starry sky, the love of his life

"72 years of life

It seems like they came here just for FAST."

24 years

From site selection, project establishment, feasibility study

To guide the research and model testing of various key technologies

Nan Rendong devoted his entire life to

This "great national weapon"

His eyes are closed

China's "eye of the sky" is slowly opening

The history of world astronomy has changed because of him

Whenever I hear his name

We can always cry with pride

Not just Nan Rendong

Looking at the long river of time

Those figures came one after another

Science and technology again and again

Behind the innovation breakthrough

Generations of scientists

Long-term hard work and perseverance

Salute to the role model of the times, Nan Rendong!

Salute to all of them!
