At 7:30 this morning (October 17), the Shenzhou 11 manned spacecraft was successfully launched. After the mission headquarters decided to study, the flight crew was composed of astronauts Jing Haipeng and Chen Dong. Jing Haipeng was instructed. long. Among them, astronaut Jing Haipeng participated in the manned mission of Shenzhou VII and Shenzhou IX. Astronaut Chen Dong was the first to participate in a manned mission.
In this flight, Jing Haipeng and Chen Dong are two astronauts who will live in orbit for 33 days. It is the longest manned space flight in China.
Wu Ping, deputy director of the China Manned Space Engineering Office, said at the press conference of Jiuquan Satellite Launch Center on the 16th that with the increase of space flight time, the adverse effects of space weightlessness on the human body will become more and more serious, especially cardiovascular. The problem of systemic dysfunction will become more prominent, and there will be some degree of muscle atrophy and bone loss. In addition, after a long flight, the astronauts return to the ground when the gravity adapts to the reaction symptoms will be more obvious, and the adaptation time will be longer.

In order to protect the health of astronauts, on the basis of the Shenzhou 10 mission, the flight will take measures to ensure their healthy living and efficient work.
The first is medical supervision and medical insurance. During the flight, comprehensive use of medical inquiries, basic physiological indicators, urine routine tests, and cardiopulmonary function tests will be carried out to regularly assess the health status of astronauts; more emphasis will be placed on strengthening microbial control in the cabin, and preventive treatment drugs and related Medical equipment to ensure the health of astronauts during the flight. In addition, this mission is the first time to establish a telemedicine support system for the world, to solve the problem of astronauts' on-orbit "docking" through the coordination of heaven and earth. In flight, the astronauts will undergo medical ultrasound examinations on the orbit, and the ground can detect the astronaut's cardiopulmonary function in real time, which is the first time in China's manned space flight.
The second is the protection of weight loss physiological effects. Equipped with protective equipment and exercise equipment to minimize the adverse effects of weightlessness on astronauts. For example: use the strap to solve the dizziness, nasal congestion and other discomforts in the early stage of the flight; exercise by cycling and running on the space running platform; wearing a penguin suit to work on the decline of cardiopulmonary function, muscle atrophy and bone loss Protection. Among them, the space bicycle is fixed in position and equipped with restraint equipment to prevent the astronauts from floating up. The relevant sports resistance wattages are carefully designed, and the astronauts exercise for about half an hour.
The third is nutrition and health protection. Wu Ping said that this mission has further enriched aerospace foods, including nearly 100 kinds of staple foods, non-staple foods, ready-to-eat, drinks, condiments and health foods. The recipe period is 5 days, and the dietary structure is more scientific. At the same time, personality is also considered. The demand for food has enhanced the sensory acceptance of food.
The fourth is psychological support. In view of the long flight time of this mission, the psychological support for astronauts during the flight will be increased. On the basis of professional psychiatrist support, family exchanges, astronaut team support, etc., technical support means have been further improved. For example, the development of a psychological comfort system based on virtual reality technology, upgraded the world information exchange system, astronauts can communicate with the ground at any time, send mail, and audio and video exchanges with friends and relatives, in order to ease the pressure of astronauts, to ensure The mental health of the astronauts.
