China News Service, Jiuquan, June 17 (Mar Shuaisha Guo Chaokai) The Shenzhou 12 manned spacecraft successfully launched on the 17th, sending three astronauts into space.

The reporter learned from the China Aerospace Science and Industry Corporation that day that astronauts can heat food in the spacecraft’s "space kitchen" and use the "space air conditioner" to control the temperature in the cabin. The "space hospital" is also equipped with a physiological signal test box and an ECG recording device. .

  It is reported that the food heating device in the "space kitchen" is installed in the spacecraft and can quantitatively heat the astronauts' space food and beverages. The heating temperature and heating time can be controlled.

It is a white square box with three layers of heating space. Gently press the power switch, and just wait patiently for a while, the astronauts can enjoy warm meals in space.

  The spacecraft is also equipped with "space air-conditioning". The astronauts can control the temperature in the cabin by adjusting the valve opening of the gas flow control valve to ensure that the astronauts in the cabin have a suitable working temperature environment.

  The physiological signal test box is worn by the astronaut on the outside of the thigh and is only the size of a cigarette case. It can measure the three physiological indicators of the astronaut’s ECG, respiration and body temperature in real time, and download it to the ground command center for diagnosis by ground medical personnel .

  The electrocardiogram recording device is mainly used to sample, process and store the received astronaut's electrocardiogram signal, and use it for electrocardiographic data analysis after the spacecraft returns.

The device has been used many times during the astronauts' lift-off, flight, return, etc., to accompany the astronauts to complete the entire flight mission.

  It is reported that these devices have been used and verified many times in the Shenzhou series flights, and the technical status is mature.
