Almost two months into their mission, the Shenzhou-21 crew have been conducting experiments across multiple domains aboard China's space station.

China launched the Shenzhou-21 crewed spaceship on November 1, sending three taikonauts to its orbiting space station for a six-month mission.

The Shenzhou-21 crew consists of mission commander Zhang Lu and taikonauts Wu Fei and Zhang Hongzhang. The three serve as space pilot, flight engineer, and payload specialist, respectively, representing all three categories of Chinese taikonauts currently serving in the country's space endeavors.

In the field of aerospace medicine experiments, the three taikonauts used electroencephalogram (EEG) equipment to collect data for experimental projects, including metacognitive monitoring research and group brain cognition-emotion analysis and regulation, supporting the ground-based researchers' ongoing work.

In the Wentian lab module, the trio used the science glove box to collect samples of Arabidopsis thaliana, a plant that will support research on the molecular network regulation of plant stem cells.

In the field of microgravity physics, the crew completed the disassembly and reassembly of the complex fluid experiment module in the fluid physics experimental cabinet and replaced the experimental samples according to the experimental plan.

The crew members replaced the sampling cover of the plug-in gas experiment in the combustion experimental cabinet and performed cleaning and sample replacement in the containerless cabinet experimental chamber, as well as maintenance of the electrodes of the axial mechanism.

The mission crew also launched the project for in situ electrochemical optical research on lithium-ion batteries for space applications, which will fully leverage the professional advantages of payload expert Zhang to capture images of the entire process of lithium dendrite growth.

Furthermore, the three astronauts underwent medical examinations, including bone density measurements, electrocardiograms, blood pressure checks, and visual function measurements, to comprehensively assess their on-orbit health status.
