WeChat has undergone a huge change! It has been two days, but many people still don’t know...

After 6 years, WeChat's startup image has finally changed! NASA was replaced by China's Fengyun-4!

WeChat announced that the replacement is complete

Old on the left, new on the right

It’s this picture! Many people said that they have been using WeChat for three years, but they didn’t know that this photo of the earth was taken by the National Aeronautics and Space Administration of the United States and is called "Blue Marble".

From 7pm last night to now, WeChat has been completely replaced: more than 900 million people will see the full view of the Earth taken by China's Fengyun-4 satellite when they reopen WeChat!

This photo of the Earth is not simple. It was taken from above China, and the outline of the motherland is very clear. The previous one was taken by a US satellite from above Africa.

WeChat said that this change symbolizes the transition from "human origin" to "Chinese civilization", and aims to show the beautiful mountains and rivers of China to hundreds of millions of WeChat users!

A historic moment that has the whole country excited

Fengyun-4 in the skies above the motherland

Why change? Because just yesterday, when this photo was taken, the meteorological satellite "Fengyun-4" independently developed by China was officially put into use!

Never underestimate this satellite. It is the Chinese policeman standing 36,000 kilometers above the earth, staring at the earth 24 hours a day.

It can monitor and issue early warnings through 14 different channels wherever there are lightning and thunder, strong winds and rainstorms, typhoons and sandstorms, fires and floods.

At the same time, it can also monitor small-scale thunderstorms. It is also equipped with China's first lightning imaging device, which can capture 500 lightning pictures in 1 second.

What is shocking is that this is the first satellite in the world to combine an interferometer and a detector, and neither the United States nor Japan has done it!

This means that from now on, the disasters brought by nature will be fully captured by Fengyun-4, and China's disaster prevention and mitigation capabilities will be greatly enhanced.

It also means that China's satellite technology has gone from "following" to "running side by side" to "leading". It has filled three international gaps and won seven world firsts!

At this moment, experts from the China Meteorological Administration, the State Administration of Science, Technology and Industry for National Defense, and China Aerospace Science and Technology hugged each other tightly with excitement!

Thanks to WeChat and scientists

Academician Xu was excited

Thanks to WeChat! This is what Chinese companies do. If it weren’t for WeChat changing the picture, such a proud event might have been drowned out by the drama;

Thanks to the scientists! It is their 15 years of persistent efforts that have transformed China from asking foreign countries for satellite data in the past to the world asking China for satellite data today.

For 5475 days and nights, the researchers never gave up. They were still young and strong back then, but now they are middle-aged and old. Their black hair has turned white, and the years have made them more beautiful!

They said: 15 years is nothing. It is worth it to be able to tackle this tough problem that the United States and Europe have retreated from.

They said: This time we are five years ahead of Europe and the United States, which will not be able to launch until 2022. We will stand firm and make a name for ourselves in the world.

That’s right, the basic scientific research, instruments and core components, and even the innovation of the entire system of Fengyun-4 were all completed by China!

Supercomputer "Shenwei TaihuLight", mobile phone chip "Kirin 970", satellite "Fengyun 4", processor "Loongson", GPS "Beidou Navigation"...

You read it right. A powerful lineup with Chinese names and representing national strength is appearing on the world stage.

This is the strong rise of China, where “the monkeys on both sides of the river keep crying, and the boat has already passed through thousands of mountains”!

This is the return of the Chinese king who said, "One day the phoenix will soar into the sky, and I will sing throughout the world"!

Next, it’s China’s turn to shake up the world!
