Wechat 20 1 1 has been using a picture of the earth called "Blue Marbles", which is a classic of NASA. Now it will be replaced by the Earth image taken by China satellite Fengyun-4. This is the first time that WeChat has updated the design of its startup page.
The WeChat launch page "Changing Face" aims to celebrate the major technological breakthrough of Fengyun-4 series satellites. Fengyun-4 series satellite is the second generation meteorological satellite in China, and it is planned to be launched between 20 16-2040. Fengyun-4 A satellite is the first satellite in this series successfully launched in June 5438+February last year.
According to the website "Critical Point" of the United States, the center of the Earth picture shown in the "Blue Marbles" image is Africa, while the center of the Earth picture shown in the satellite cloud picture taken by Fengyun-4 is China.
Regarding the reason for choosing this photo as the material, the WeChat team revealed: "The African continent is the origin of human civilization. We use the cloud picture over Africa as the background picture of the startup page, and we also want to give the startup page the meaning of' origin'. Because of the appearance of human beings, there is the existence and significance of communication. The display of Fengyun No.4 photo also symbolizes the historical development from "the origin of human beings" to "Chinese civilization", aiming to show hundreds of millions of WeChat users the landscape of China.
