CCTV News: The "space business trip" of the Shenzhou 19 astronaut crew is about to enter the countdown. Last week, the Shen 19th Crew Group steadily promoted various scientific space experiments, and actively carried out health maintenance while carrying out on-site environmental monitoring, equipment inspection and maintenance.

The Shen 19th Crew used electroencephalo equipment to carry out a number of experimental testing work. Ground researchers will use the acquired data to explore the impact of gravity on the processing process of visual motion information, reveal the cognitive laws of human relations in the spatial microgravity environment and its neural basis, and explore the regulatory role of brain wave music intervention on the long-term spatial flight inhibition control function.

How did you feel about living and working in "Space House" for nearly half a year? The crew uses filling in questionnaires and shooting videos to collect data such as comprehensive living experience of the space station, real-time feedback on human-computer interfaces, and layout of facilities and equipment in specific areas. Ground researchers will conduct research based on downward data, locate, analyze problems, summarize design experience, and make targeted and systematic suggestions to improve the overall human habitability of the spacecraft.

In addition, astronauts have completed relevant work on pharmacokinetic research in orbit, accumulated relevant data, and provided a reference for subsequent guidance on orbital medication.

In the field of aerospace technology testing, the load tank assembly and testing of the space inverse Breton large-cooling refrigeration technology test project is carried out as planned. The project is aimed at the needs of follow-up tasks such as deep space exploration, and conducts tests and verifications of inverse Breton's large-cooling refrigeration technology based on ultra-high-speed dynamic pressure air-floating bearings, which is expected to improve my country's space thermal control technology level and provide technical support for future aerospace mission applications.

Many experimental projects in the field of microgravity physics science are underway, and the crew has completed a number of tasks such as replacement of experimental samples, vacuum exhaust and exhaust gas.

Last week, three astronauts completed a number of environmental monitoring work such as wind speed and temperature measurement, air cleanliness test, and conducted routine inspections and maintenance of the equipment in the station.

In addition, astronauts carried out a number of medical examinations such as electrocardiogram, motor lung function, dynamic electrocardiovascular blood pressure, and actively carried out weightless protection.
