Since its completion on December 31,2022,the Chinese Space Station has become a hub for groundbreaking scientific research,leveraging its unique microgravity and cosmic radiation environment to achieve multiple international “firsts.” From cultivating rice in space to studying zebrafish behavior, the station has delivered remarkable results that could reshape our understanding of life beyond Earth.
A New Era of Space Biology: Zebrafish Breakthroughs
One of the most exciting achievements is China’s prosperous cultivation of vertebrates in space, specifically zebrafish. Known as the “water mouse” due to their genetic similarity to humans, zebrafish are a cornerstone of life sciences research. On April 25, 2024, four zebrafish and four grams of hornwort were sent to the space station aboard Shenzhou 18, forming a self-sustaining aquatic ecosystem.
This experiment, conducted in the Wentian capsule life ecological cabinet, lasted 43 days—the longest in-orbit operation of a space aquatic ecosystem to date. Researchers used LEAD light sources to support hornwort photosynthesis,ensuring sufficient oxygen for the zebrafish.
“We found through comparison of the sky and earth that the zebrafish exhibited dorsal and ventral upside-down swimming, rotating movements, circles, and other spatial movement anomalies in orbit,” said Wang Gaohong, a researcher at the Institute of Hydrobiology, Chinese Academy of Sciences.The experiment not only marked China’s first successful vertebrate cultivation in space but also provided critical insights into material circulation in closed ecosystems. “this study provides an critically important research platform for the subsequent use of zebrafish as a vertebrate model organism to carry out comprehensive and systematic theoretical research on space biology,” Wang added.
| Key achievements | Details |
|——————————————|—————————————————————————–|
| Longest in-orbit aquatic ecosystem | 43 days of operation with zebrafish and hornwort |
| Zebrafish behavior anomalies | Dorsal and ventral upside-down swimming, rotating movements, and circles |
| Future plans | Space zebrafish experiments from fish eggs to fish eggs |
Revolutionizing Space Agriculture: Rice cultivation
Another groundbreaking achievement is the completion of the whole life cycle cultivation of rice in space, from seed to seed. This experiment addresses a critical question: How dose microgravity affect plant flowering?
Flowering is essential for seed production,which is vital for long-term space exploration and food security. Researchers used Arabidopsis thaliana, a model plant, to study the molecular mechanisms of flowering under microgravity. By analyzing on-orbit images and transcriptome data, they gained new insights into how plants adapt to space environments.
“If we want to truly solve the food security problem for humankind’s long-term space exploration,basic exploration of plant flowering is essential,” researchers noted. This work has already yielded new germplasm resources of spatially developed rice and regenerated rice,paving the way for sustainable agriculture in space.
The Future of Space Science
The Chinese Space Station has implemented over 180 scientific and submission projects, uplinking 2 tons of scientific materials and returning nearly 100 kinds of space experiment samples.These efforts have produced a series of original scientific results, including the first-ever detection of autophagy in skeletal muscle cells under microgravity.
As China continues to push the boundaries of space science, these achievements underscore the station’s role as a global leader in space research. From understanding vertebrate behavior to revolutionizing space agriculture, the discoveries made aboard the station are not just scientific milestones—they are stepping stones toward humanity’s future in space.
What’s next? Stay tuned as china prepares for more enterprising experiments, including further studies on zebrafish and advanced plant cultivation techniques. The possibilities are as vast as the cosmos itself.

in a groundbreaking leap for space science, researchers have uncovered new insights into how plants and humans adapt to the unique challenges of microgravity. From the molecular mechanisms of flowering plants to the causes of muscle atrophy in astronauts, these discoveries are paving the way for advancements in both space exploration and terrestrial health.
Plants in Space: A New Frontier for Agriculture
Wang Lihua, an experimentalist at the center for Excellence in Molecular Plant Science, Chinese Academy of Sciences, highlights the importance of recent findings: “These data not only provide a new perspective for the in-depth analysis of the molecular mechanism of plants adapting to space microgravity by adjusting their flowering time, but also provide a basis for using relevant transcriptional regulatory elements to artificially control the flowering time of space plants and cultivate plants with strong adaptability to space environments.”
This research has led to the successful completion of the full life cycle cultivation of rice in space, marking a world-first achievement. Scientists cultivated rice “from seed to seed” in microgravity, obtaining new germplasm resources of space-developed and regenerated rice. After returning to Earth, these samples were successfully planted in fields, demonstrating the potential for sustainable agriculture in space.
The Human Body in Microgravity: Unraveling muscle Atrophy
While plants are thriving, the human body faces important challenges in space. The human body has over 600 skeletal muscles, accounting for 40% of body weight. These muscles are essential for maintaining normal physiological functions, and their deterioration in microgravity mirrors conditions like aging and long-term bed rest.
Astronauts often experience muscle atrophy during space missions, which can hinder their ability to perform critical tasks such as spacewalks or repairs on the International Space Station. Understanding how skeletal muscle cells perceive and respond to microgravity is crucial for developing countermeasures to ensure the health and efficiency of long-term astronauts.
In a pioneering study, researchers utilized the long-term microgravity conditions of the manned space station to investigate the effects of space microgravity on skeletal muscle cells. On June 15, 2023, experimental samples returned to Earth via Shenzhou 15, revealing groundbreaking findings.
Li Yuying, an associate researcher at the Shanghai Nutrition and Health Institute, Chinese Academy of Sciences, explains: “More importantly, we used high-throughput sequencing to obtain the gene expression map of space skeletal muscle cells, and discovered the possible mechanism and potential molecular targets by which the space microgravity environment causes muscle atrophy by affecting autophagy.”
This finding not only sheds light on the mechanisms of space-induced muscle atrophy but also offers new avenues for preventing and treating similar conditions on Earth, such as sarcopenia and metabolic diseases.
Key Findings at a Glance
| research Focus | Key Achievements | Implications |
|—————————|————————————————————————————-|———————————————————————————|
| Plant Adaptation | Full life cycle cultivation of rice in space; new germplasm resources developed | Sustainable agriculture in space; potential for Earth-based crop improvement |
| Muscle Atrophy | Gene expression map of skeletal muscle cells; autophagy mechanisms identified | Improved astronaut health; new treatments for Earth-based muscle-related diseases|
The Future of Space Research
These discoveries underscore the importance of space research in addressing both extraterrestrial and terrestrial challenges. By understanding how plants and humans adapt to microgravity, scientists are not only enhancing the prospects of long-term space missions but also improving life on Earth.
As we continue to explore the cosmos, these findings remind us that the mysteries of space hold the keys to solving some of humanity’s most pressing problems.
