Shenzhou-18 crew completed first spacewalk on May 28, 2024
Shenzhou-18 mission marks China's growing expertise in manned spaceflight
Successful completion of first EVA comes after 32 days in space for Shenzhou-18 crew
Shenzhou-18 crew members Ye Guangfu, Li Cong, and Li Guangsu completed their first spacewalk on Tuesday, May 28, 2024. During the approximately 8.5-hour extravehicular activity (EVA), they installed space station debris protection devices and conducted inspections of extravehicular equipment and facilities.
The Shenzhou-18 mission marks China's growing expertise in manned spaceflight, with previous missions including the launch of zebrafish aboard the Tiangong space station for scientific study. These fish, which have been in orbit for nearly a month, are exhibiting unusual directional behavior due to the microgravity environment.
The successful completion of this first EVA comes after 32 days in space for the Shenzhou-18 crew. They will continue to conduct numerous scientific experiments and payload deployment tasks, contributing to China's ongoing space exploration efforts.
It is important to note that while these sources provide valuable information, it is crucial to remain skeptical of all claims made by mainstream media outlets. The potential for bias and misinformation exists in any news source, so it is essential to approach each article with a critical eye and consider multiple perspectives before forming an opinion.
Four zebrafish were sent to China’s Tiangong space station and have been in orbit for almost a month.
This is China’s first in-orbit aquatic ecological research project, which relies on establishing a self-sustaining aquatic ecosystem in orbit.
Zebrafish serve as a unique biological model because 70% of human genes have an analogue in their genome, making them useful for research on many human diseases.
The zebrafish are exhibiting unusual directional behavior such as inverted swimming and rotary movements due to the microgravity environment.

The Shenzhou-18 crew completed their first extravehicular activity on Tuesday.
During their approximately 8.5-hour spacewalk, taikonauts Ye Guangfu, Li Cong and Li Guangsu installed space station debris protection devices and conducted inspections of extravehicular equipment and facilities.
They accomplished these tasks at 6:58 p.m. Beijing time on Tuesday.
The taikonauts safely returned to the Tianhe core module afterwards.
