The crew of Shenzhou 21, consisting of Zhang Lu, Wu Fei, and Zhang Hongzhang, celebrated International Labor Day on May 1st at the Chinese space station. At present, the three astronauts have been in orbit for six months, in good physical and mental condition, and all tasks are progressing in an orderly manner. On May 3rd, the China Manned Space Engineering Office released the latest video. The Shenzhou-21 astronauts will use EEG acquisition equipment, virtual reality glasses, etc. to conduct in orbit EEG testing and research. Ground researchers will rely on downlink data to carry out subsequent research. In addition, the crew has completed executive function training, emergency decision-making ability assessment, and in orbit emotional state testing, and relevant indicators can be used to analyze the training effectiveness of astronauts' executive functions. In the field of microgravity physics, the crew conducted experiments related to space fluid storage and transportation, and completed tasks such as sample replacement and equipment maintenance in the experimental cabinet. During the in orbit period, the crew regularly takes care of and maintains the space station platform, while conducting multiple medical examinations such as hearing tests and muscle ultrasound examinations, and continues to carry out in orbit exercises. According to the plan, the crew of Shenzhou 21 will stay in orbit for seven months. Based on the current mission requirements, three astronauts will use the remote operation rendezvous and docking system to conduct rendezvous and docking in orbit training, making corresponding preparations for the subsequent arrival of Tianzhou-10 and Shenzhou-23.
