Space missions always arrange for Nie Haisheng, Liu Boming and Tang Hongbo to go into space, so what is their first task after entering the space station? Start space operations? No, the first thing they do is "open the courier".
This space mission not only verified the key technology of the space station for the fourth time, but also completed the first manned mission on the space station. According to the plan, the three astronauts need to stay in the space station for up to three months, and then return to the Dongfeng landing site by spaceship. After staying in the space station for such a long time, it is natural that the materials should be well prepared.
The astronauts arrived at the space station by Shenzhou, and the materials were transported by Tianzhou cargo spacecraft. As early as May 29th this year, Tianzhou-2 cargo spacecraft delivered 6.6 tons of materials to the space station, including 160 pieces of goods and nearly 2 tons of propellant. The astronauts' first task after entering the space station is to sort out and disassemble these materials.
In addition to propellant and experimental equipment, a large part of it is the living materials of astronauts for three months. These goods use RFID (radio frequency identification technology), and astronauts can quickly find them by scanning the codes on the outer packaging when carrying and looking for materials; After these things are used up, they need to be packaged and sealed and scanned into the system, so that the whole process can be efficient and convenient. In this way, it is not difficult for astronauts to find a fish-flavored shredded pork from the vast amount of materials.
When it comes to the life of astronauts in the space station, people in China often say that "food is the most important thing for the people", and the diet of astronauts is also very important. There are three standards for their meals: first, balanced nutrition; Second, solid, small, no residue; Third, ensure the appetite of astronauts.
As early as 2003, although Shenzhou 5 roamed the universe for 2 1 hour, the spacecraft was also equipped with traditional China dishes such as braised pork and fish balls. When Yang Liwei's children talked to him, they asked him if he had eaten. He also replied with a relaxed face: "I have eaten it, which is particularly delicious and delicious."
The Shenzhou VI mission in 2005 lasted for three days, and this time it carried more than 40 kinds of food. Astronauts can use heaters, eat hot meals and even eat ice cream desserts after meals. In the subsequent mission, not only the types of food were expanded, but also the personal tastes of astronauts were taken into account on the menu. For example, several astronauts of Shenzhou-10 prepared rice from Nie Haisheng, mature vinegar from Zhang and red bean paste zongzi from Wang Yaping.
What shocked Chinese and foreign audiences even more may be that during the Shenzhou XI in 20 16, Jing Haipeng and Chen Dong personally collected fresh lettuce in the spaceship.
In this year's mission, Tiangong Space Station is equipped with a super-large refrigerator, which is made of nano-aerogels and used on the Zhu Rong Mars vehicle.
Not only the diet is constantly improving, but also the aviation suits are being adjusted. In the live video, when three astronauts are waiting to enter the cabin, there is a small box next to everyone. This box is actually a ventilator, which is equivalent to a portable air conditioner. Because the air suit requires good air tightness, air can't convection. Under normal circumstances, astronauts not only have to wear heavy clothes, but also endure the sweltering heat, which is really a physical challenge. The spacesuit developed in the past has met the practical requirements. In recent years, the staff mainly improved the adaptability of spacesuits.
From the excitement and wonder of thousands of people flying in the sky in ancient times to the pride and excitement of China people caused by the first manned space flight of Shenzhou V, China's space industry has innovated again and again, breaking discipline again and again, which has become a microcosm of the development of the China era. Now, even if astronauts have to stay in the space station for three months, we have many times more confidence in our worries.
The chief designer of the Long March II F rocket smiled easily when interviewed: "We have already eaten steamed buns." This is actually a tradition of rocket launching system. At first, in order to replenish food quickly and conveniently, the staff ate steamed bread while waiting for the launch. Later, the steamed stuffed bun became the carrier of China people's beautiful meaning: it was wrapped completely and successfully. I look forward to and wish that this space mission can be successfully completed and the three astronauts can return safely as scheduled!
