1. Carry out the daily management of core module assembly, including the on-orbit test of Sky and core module.
To put it figuratively, it is "unpacking express delivery". When the core cabin of the space station was launched, "Express Brother" Tianzhou II packed and transported more than 6 tons of "equipment". At that time, many of them could not be installed at the station. Therefore, after the three astronauts leave the cabin, it may be necessary to dismantle the courier, and many equipment are waiting for manual installation, start-up and debugging.
2. Verification of regeneration support system and astronauts' own health management.
Because it will stay in orbit for three months, and for the long-term economic operation, "Space House" is different from previous space laboratories. The environmental control and life support system in the core cabin of the space station adopts renewable technology.
Astronauts should recycle the oxygen and water in the space station as much as possible. In addition, astronauts should do physical exercise as planned, and regularly monitor, maintain and evaluate their own health.
3. Conduct space science experiments and technical experiments.
Assemble and test experimental equipment for space application tasks, carry out practical (trial) experiments in the fields of space application and aerospace medicine according to procedures, and related popular science education activities. The fourth task is very interesting-astronauts will use robotic arms to complete extravehicular operations during their stay.
Astronauts have to carry out two extravehicular activities and extravehicular operations, including on-orbit transfer, extravehicular clothing assembly and testing, extravehicular toolbox assembly, panorama camera lifting and expansion pump set installation.
Contents of astronaut selection
1, basic conditions: same as pilots, but with higher education level and working ability.
2. Medical choice: In addition to following the pilot's medical choice conditions, we should also pay attention to whether there is hidden neuroendocrine system dysfunction in the past medical history. Physical examination should comprehensively and carefully check the cardiovascular system, vestibular function and visual system.
3. Psychological selection: Psychological quality selection is an important aspect of astronaut selection. It is necessary to find out personality, emotional stability, mental state, adaptability and coordination ability with people.
4. Choice of special environmental endurance: In the early days of manned space flight, people attached great importance to the choice of special environmental endurance. However, with the continuous development of space technology and the gradual improvement of manned spacecraft environment, some special environmental factors such as noise, vibration and temperature are no longer the main content of choice.
The selection of endurance in special environment mainly includes the tests of weightlessness adaptability and return adaptability, such as vestibular function test, overweight endurance test, low pressure hypoxia endurance test and so on.
