A new video spotlights the Shenzhou-21 crew members — Zhang Lu, Wu Fei, and Zhang Hongzhang — on board China’s Tiangong space station.
The trio of taikonauts has been conducting multiple science experiments, including their first full-system emergency response drills in orbit over the past week.
The threesome have been in orbit for a month as of today.
Microgravity experiments
According to a China Central Television (CCTV) broadcast, the crew performed microgravity experiments on intuitive physical behavior, collecting relevant behavioral data to explore “the impact of long-term spaceflight on human’s intuitive physical representations and the mechanisms of their recovery.”
In use has been a Raman spectrometer to analyze metabolic components in urine samples. Additionally, the crew completed the installation of new software for space medical experiments.

Medical exams
In addition, they underwent multiple medical examinations, including non-invasive cardiac function tests, providing data for ground teams to closely monitor their health in orbit.
The crew completed scheduled tasks including replacing the high-speed image storage unit in the two-phase system experiment cabinet and disassembling and assembling experimental modules.
They also cleaned and replaced samples within the containerless cabinet’s experimental chamber and cleaned window cover lenses, CCTV adds.

Emergency drills
Also undertaken by the Shenzhou-21 crew: Conducting their first full-system emergency pressure response drills. They simulated emergency actions to be taken in the event of an internal depressurization scenario.
This crew was involved in China’s first emergency mission – the rapid launch of an operable (and uncrewed) Shenzhou-22 spacecraft to replace a purported space debris-damaged Shenzhou-20 lifeboat. It remains attached to the space facility.

Lastly, the crew performed patrols of the cryogenic storage units and the minus 80-degree space refrigerator, CCTV notes, and appraising pressures in the environmental control gas cylinder, and conducted maintenance on the regenerative life support system equipment.
