Hello everyone, I am the panda wl3 who loves life. Today, I bring the following article

The development of manned spaceflight in China has entered a fast lane, and the living conditions and training methods of astronauts have undergone significant changes. During the Shenzhou-5 flight, Yang Liwei only slept for half an hour, and because time was precious, his experience and feelings became the first first-hand experience that Chinese astronauts had gained in space. In the past decade, China's manned space program has made satisfactory progress. In the early learning stage, astronauts did not have simulators, so Yang Liwei spent over 10000 yuan to purchase a camera to record the learning and training process.

Now, astronauts can learn in a one-to-one space station simulator. The mission started less than a year before the simulator was developed, allowing astronauts to learn and train in it. Astronauts work in the space station simulator for a month to simulate their work and life before executing the mission. The design of a space station simulator allows astronauts to easily operate and control their body and posture within it. The bedroom of the space station has cabinets and dining areas. There is a hanging window in the private space that allows you to look out. The entire space station has approximately 50 cubic meters, while Yang Liwei only had 6 cubic meters during his flight.

Astronauts will carry a bellows during their expedition to ventilate and prevent them from feeling hot. The conditions of the space station have become very good. Astronaut Yang Liwei stated that their space suit is much more complex than regular clothing. It is a miniature version of a small spacecraft that has heat, flame retardancy, and radiation protection functions. The space suit is composed of many different layers and has multiple air tightness. The weight of the entire garment exceeds 120 kilograms. Compared to the Shenzhou-7 flight, the spacesuit has undergone many improvements and now has working hours greater than eight hours.

The spacesuit is also equipped with feces and urine collection devices, as well as deodorization devices. Urine can be consumed after treatment, and the current recovery rate has reached over 85%. The astronauts also introduced the development of environmental control and life support systems, stating that they are now regenerative, while in the early days they were portable. This improvement can reduce upward pressure. Regarding the changes in training methods, Yang Liwei stated that the current training is more scientific and targeted. Basic training for astronauts is still ongoing, and evaluations will be conducted annually. Yang Liwei also shared his excellent performance in centrifuge and rotary chair training.

In summary, the training methods and equipment of astronauts are constantly improving, and the tasks they face are also becoming more complex. Chinese astronaut Yang Liwei stated that the most important qualities of astronauts are perseverance and hard work. He revealed that although they had regrets, they were also envious of seeing other batches of astronauts complete multiple flights. Yang Liwei emphasized that national interests are above all else, and even if one has to sacrifice one's life, it is still worth it. He recalled the scene when the Shenzhou-1 spacecraft was launched, and the astronauts resolutely went up to the sky with 50% safety assurance.

He pointed out that the belief embedded in the hearts of astronauts since the establishment of the aerospace industry is that the interests of the motherland are above all else. Yang Liwei stated that in the past 20 years, there have been many changes in aerospace engineering, but the original intentions of astronauts remain the same. He said that space exploration is an eternal expedition on the road. As China's space station enters the stage of application and development, Chinese astronauts are also preparing to move towards deep space. Yang Liwei mentioned that the next goal is to launch a manned lunar landing.

At present, China is conducting the selection of the fourth batch of astronauts. Considering the needs of lunar missions, astronauts need to experience space station flights and gain corresponding experience. In addition, due to the 1/6 gravity on the moon, astronauts need coordination and maneuverability during operations, so the training program also needs to be adjusted accordingly. Yang Liwei pointed out that in order to achieve manned lunar landing, the astronaut system has begun preparations, including the development of training facilities. Manned spaceflight is a very complex project that requires various training programs and the development of specific outlines.

At present, the research and development work has entered the clothing stage. When selecting a manned lunar landing crew, it is necessary to have rich flight experience and experience, as well as better psychological qualities, as the flight distance for lunar landing is longer. Moreover, the ultimate goal of manned spaceflight is not to land on the moon, but to explore deeper space, which is also a goal for serving humanity.
