视频丨“太空出差”已超三个月 神二十一乘组完成多项实验与维护

Core Viewpoint - The Shenzhou 21 crew's space mission has been ongoing for over three months, with various scientific experiments and maintenance tasks being conducted systematically within the space station [1]. Group 1: Space Science Experiments - In the field of aerospace medicine, the crew has completed blood sample collection and processing, which will be used to study the physiological changes and adaptation mechanisms of astronauts' skeletal, neural, and cerebrovascular systems during long-duration flights [2]. - The crew is conducting experiments related to the impact of microgravity on visual asymmetry and its cognitive neural mechanisms using a laptop [4]. Group 2: Equipment Maintenance and Environmental Monitoring - The crew has performed various maintenance tasks, including cleaning experimental samples, maintaining electrode mechanisms, and replacing experimental samples in fluid dynamics modules [4]. - Environmental monitoring has been conducted using devices like dew point meters to assess the thermal environment inside the station, along with air cleanliness testing [6]. Group 3: Health Management - Astronauts are utilizing devices with adhesive properties to stimulate lower limb flexor muscles during exercise in a weightless environment, fulfilling their exercise requirements [8]. - Multiple medical examinations have been completed, including eye pressure checks, overall vision function measurements, and orbital B-scan measurements [8].
