? Just today, the return capsule of Shenzhou 13 manned spacecraft successfully landed in the scheduled area of Dongfeng landing site! The three space heroes who carried out the mission-Zhai Zhigang, Wang Yaping and Ye Guangfu-felt good and got out of the cabin smoothly, and the manned mission of Shenzhou XIII was a complete success. Many netizens also stayed in the live broadcast room early, hoping to witness this prestigious and exciting moment. As for the popular science knowledge about the details of Shenzhou's return flight, I believe many friends are as curious as me, so let's take a look ~

What tasks did the three outstanding astronauts accomplish in orbit for half a year?

? These six months are not just six months of living in space. On the basis of Shenzhou XII, they completed more than 20 scientific experiments, two extravehicular activities and two space "Tiangong lectures" and so on. It can be said that the harvest is quite fruitful, and this long space trip is also a breakthrough feat destined to go down in history. This is a romantic and world-class expedition to the sea of stars, which declares to the world the manned space spirit that belongs only to the Chinese nation.

Do you need to prepare anything before the return of the space travel trio?

? Entering the countdown and returning to the preparation stage, our Coco Love Trio has also begun to actively exercise, enhance physical fitness and "pack up". For example, there are a lot of research results and materials to be sorted out, products and equipment to be in place, and "cleaning" to be carried out. At the same time, it will also bring back a "space cargo package" with great research value, including space seeds with high attention. In order to ensure the safety of personnel, physical and mental health examination should be carried out item by item. It can be said that the work of researchers in space or at any time is in full swing and interlocking.

At such an exciting moment, will the astronauts "burst into tears"?

? In fact, friends who have paid attention to the Tiangong classroom will know such a cold knowledge: astronauts can't cry in the sky. Because astronauts have also experienced many moments of excitement and want to cry during their space work, they found that in this extremely special situation, tears could not flow smoothly to their faces, that is, they could not flow naturally. So I can only "hold back my tears and pretend to be strong", spinning in my eyes or staying in the corner of my eyes.

Expedition to the sea of stars is the endless journey of great astronauts from generation to generation, and it is also a moment worthy of pride and tears for all China people. I hope that each of us can shine in our own field and move forward forever.
