Chinese Astronauts Raised Zebrafish in Space

During the Shenzhou-18 mission, Chinese scientists successfully raised zebrafish in a closed aquatic ecosystem in space, marking a significant milestone in space biology. The experiment demonstrated a full zebrafish lifecycle under microgravity, providing critical insights into sustaining life in space. Zebrafish, chosen for their genetic similarities to humans, enable efficient study of biological processes. This achievement is vital for developing life-support systems for long-term missions, including Mars exploration. The research underscores China’s growing role in space science and lays a foundation for future studies on sustainable ecosystems for space habitation.
