Vision requirements for astronauts

There were differences in the recruitment standards for astronauts in different countries: ** 1. China ** 1. ** Physical condition ** - In the early stages, the height requirement was 1.6 - 1.72 meters and the weight was no more than 70 kilograms, but it was adjusted according to different batches. For example, in the second batch of astronauts, the height of men was 1.62 - 1.75 meters, the height of women was 1.60 - 1.75 meters, the weight of men was 50 - 74 kilograms, and that of women was 48 - 74 kilograms. - At least three years of physical examination report is Class A, no fatty liver, high blood pressure and other diseases. - Strong physique, no color blindness. 2. ** Age Requirement ** - The selection age was usually between 25 and 35 years old, but the actual age range of astronauts performing the mission was wider. 3. ** Flight duration requirement ** - The flight time was no less than 600 hours. 4. ** Education and Ability Requirements ** - Bachelor's, Master's or PhD degree in engineering, physics, biology or mathematics. - Proficient in at least one foreign language. - Able to pilot a plane, with more than 100 hours of flying experience. - Possesses very good psychological abilities, including the ability to resist setbacks and psychological stability. With the development of the aerospace industry, astronauts had to master more special skills from the selection stage. For example, the fourth batch of astronauts had to master geological knowledge, which might require field practice, geological investigation, and so on. They also had to participate in the development of aerospace engineering. The load specialists had to play an important role in the space mission with their own knowledge reserves. At the same time, astronauts had to undergo a variety of training related to the aerospace environment, including weightless operation, spacewalking, emergency response, and so on. They also had to learn the structure of the spacecraft, its working principles, and the operation methods of scientific experiments. ** 2. America ** 1. ** Physical condition ** - The height requirement was 1.52 - 1.93 meters, and the weight was 45 - 109 kilograms. 2. ** Age and Knowledge Requirement ** - Age was not explicitly mentioned, but the space candidate had to be over 20 years old (presumably). - Must have a master's degree in natural science, a driving and flight certificate, and at least two years of work experience in NASA research.

There were a variety of products called the Astronaut Cup. One of them was a space cup specially designed for astronauts. It had a strange shape and was shaped like a V. One end was a very thin gap. Using the phenomenon of capillarity and the surface tension of the liquid, it could allow the liquid to tightly adhere to the cup wall and flow into the mouth along the cup wall. The astronauts could drink water along the sharp mouth. There were also some cups with the image of astronauts, such as Terrigel's new cartoon planet mug, landscape cover, ceramic cup, and large capacity water cup for astronauts. The unit price of the promotion in Jingdong was 51 yuan per piece. There were also 2024 Internet celebrity astronauts, water dispenser, and water dispenser for children to go to school. The place of origin was Yiwu. The material was food grade plastic, and there were different colors and specifications. The price was between 31.66 and 59.97. In addition, NASA astronaut Donald Pettitte designed a capillary-cup (zero-gravity cup) on the International Space Station. This was an open drinking cup that stemmed from the desire to drink water in outer space without a bag or straw. It could be used in microgravity environments.

The names of the astronauts of Divine Nine were Jing Haipeng, Liu Wang, and Liu Yang. The names of the Shenshi astronauts were Nie Haisheng, Zhang Xiaoguang, and Wang Yaping.

I recommend the two novels," Bravehearts from the Other World " and " The Elf Summoner from Earth." " Brave Man from the Other World " told the story of an astronaut who traveled to another world and embarked on a journey with a beautiful girl. " The Elf Summoner from Earth " was a story about an astronaut who traveled to another world. The protagonist became a summoner in the other world. These two novels were in line with the theme of transmigrating into astronauts.

The astronauts of Shenzhou 13 were composed of Zhai Zhigang, Wang Yaping, and Ye Guangfu. Zhai Zhigang was China's first extraterrestrial astronaut, Wang Yaping had carried out the Shenzhou-10 manned mission, and Ye Guangfu was the first to fly in space. Zhai Zhigang was the commander of this mission. In this mission, the astronauts would stay in orbit for six months, and Chinese female astronauts would also be stationed on the China Space Station for the first time. They had successfully completed many extraterrestrial activities and missions.

The Shenzhou 12 astronauts were Nie Haisheng, Liu Boming, and Tang Hongbo. On June 17,2021, they successfully flew into the sky on the Shenzhou 12 manned spacecraft, becoming the first batch of people to enter the China Space Station's Sky and Core module. In the space station, the astronauts carried out a series of operational tasks such as extraterrestrial maintenance, equipment replacement, and scientific application of payloads, setting a new record for the duration of a single flight for Chinese astronauts. They also carried out a spacewalk and completed the real construction task. The astronauts lived in space for nearly a month. They chased after food in space and carried out activities such as space fitness. The mission of the Shenzhou 12 astronauts was a complete success on September 17,2021. The return capsule successfully landed at the Dongfeng landing site, and the astronauts safely and smoothly exited the capsule. This mission marked the beginning of the space station phase of China's manned spaceflight project.

The Shenzhou 12 astronauts needed to go through a number of steps to return to Earth. From the separation of the spacecraft from the core module to the final return to the ground, the astronauts needed more than 20 hours. During this time, the astronauts had completed the space station's evacuation, orbit, and rendezvous tests, which meant that they had completed the first two steps of the return. The specific return steps included: separating the spacecraft from the core module, changing into the cabin pressure suit, conducting the flight around test and the radial-intersection test, entering the return orbit, entering the atmosphere, passing through the " black barrier " area, opening the guide parachute, the deceleration parachute, and the main parachute, and decelerating the descent with the parachute. During the return process, the astronauts had to withstand a huge overload and high temperature, but because of the use of special materials, the astronauts could not feel any obvious temperature changes in the cabin. Finally, the astronauts would land safely through the Dongfeng landing field. In general, the Shenzhou 12 astronauts needed to go through multiple steps to return to Earth. Each step was to ensure their safe return and smooth landing.

The crew of Shenzhou 17 consisted of three astronauts, Tang Hongbo, Tang Shengjie, and Jiang Xinlin. Tang Hongbo served as the commander. The crew consisted of one second-batch astronaut and two third-batch astronauts. They were the youngest astronauts on average since the start of the space station construction mission. Tang Hongbo was a first-class astronaut of the Chinese People's Liberation Army Astronauts Brigade. He was a senior colonel in the Army and had a master's degree. He was once the captain of a certain regiment of the Air Force and was awarded the title of Air Force First Class pilot. Tang Shengjie was born in 1989 and was the youngest in this round. Before he became an astronaut, he was an excellent Air Force pilot. His flight path spread all over the country and he was rated as a first-class pilot of the Air Force. Jiang Xinlin had little personal information, but he was also a member of the astronauts. The Shenzhou-17 astronauts had successfully completed many missions, including extraterrestrial maintenance missions and space science and technology experiments.

The Shenzhou-16 astronauts were composed of Jing Haipeng, Zhu Yangzhu, and Gui Haichao.
