1. Various of Shenzhou-21 astronauts conducting experiments, replacing and maintaining equipment, exercising on space station
More than 160 days into their mission aboard China's space station Tiangong, the Shenzhou-21 astronauts Zhang Lu, Wu Fei, and Zhang Hongzhang have conducted various in-orbit experiments, facility maintenance, and health checks.
Last week, the crew used a space Raman spectrometer to analyze metabolic components in urine samples, which will aid in refining and improving indicators and criteria for astronauts' metabolite. The astronauts also collected and froze saliva samples to assist underground researchers in studies on gut microbiota and gastrointestinal function.
In line with their experimental plans involving bone metabolism, circadian rhythms and sleep, the crew collected blood samples, processed them using a centrifuge, and stored them for analysis. They also conducted multiple tests on metacognitive monitoring, emergency decision-making assessments, and evaluations of their emotional states using a laptop and related apps.
The team carried out planned experiments in microgravity physical sciences, and replaced samples in the fluid physics experimental cabinet, and burners and gas cylinders in the combustion cabinet as well. They also cleaned the containerless experimental chamber and maintained electrode mechanisms.
In addition, the astronauts checked and maintained low-temperature storage devices, application fluid loop pumps, and other facilities as scheduled, while organizing supplies within the cabin.
Meanwhile, the astronauts continued their health management by using a space treadmill and resistance bands for on-orbit exercise, actively countering the physiological effects of weightlessness.
The Shenzhou-21 crewed spacecraft blasted off from the Jiuquan Satellite Launch Center in northwest China on Oct 31, 2025, sending the three astronauts to the orbiting space station on a six-month mission.
