China Focus: China's "mice astronauts" and their challenging journey to space
Source: Xinhua Editor: huaxia 2025-11-04 14:55:31

BEIJING, Nov. 4 (Xinhua) -- Footage of four mice living aboard China's space station alongside the Shenzhou-21 astronaut crew has recently been transmitted back to Earth, revealing these small animals in good spirits and in an apparent state of well-being.

The video shows astronauts retrieving the experiment facilities containing the mice from a specialized transport bag. They then installed the facilities in orbit and connected them to the power supply. Once activated, the device maintained a stable internal temperature of around 26 degrees Celsius.

In the footage, the mice can be seen taking turns resting in shelter nests inside the facilities and occasionally climbing actively along the cage walls -- appearing lively and well-adapted.

They quickly located the rodent food and began eating while making slight head movements, exhibiting normal feeding behavior after their arrival on the space station. The shelter nests also proved functional, offering the mice a sense of security.

When the facilities were initially unpacked, floating feces and food debris were visible inside. After powering on the facilities, directional air flow within them was activated to blow hair, feces and other garbage toward a sticky surface at the bottom -- ensuring a clean and hygienic environment for the mice.

As a key model animal in the field of life sciences, mice feature several advantages -- high genetic similarity to humans, small body size and short reproductive cycle, and a high amenability to genetic modification, said Huang Kun, an expert from the Technology and Engineering Center for Space Utilization of the Chinese Academy of Sciences (CAS).

"These traits make them ideal for studying physiological and pathological processes, as well as the growth, development and reproduction of living organisms in space," he said.

To qualify as "animal astronauts," the mice underwent a series of rigorous tests designed to evaluate their physical and psychological adaptability.

The first stage assessed physical fitness, with the mice placed on a specially designed "exercise bike" -- essentially an accelerating rotating rod, where they had to maintain their position for a set duration. This tested their strength, endurance and grip.

The next challenge focused on motion sickness resistance. Using a two-dimensional rotating device, researchers exposed the mice to multi-directional, prolonged spinning -- helping them adapt to conditions that could cause space motion sickness.

Behavioral screening was also conducted. By suspending the mice upside down, researchers observed their struggle response, selecting those that actively resisted -- identified as the more resilient "optimists." Maze tests further evaluated their spatial cognition and adaptive skills, ensuring they could navigate and find food even in a weightless environment.

According to experts, after completing all tests, the mice were transferred into compact cages that simulated the space cabin environment. This allowed them to acclimate to the confined living conditions they would experience in orbit. Ultimately, the four best-performing mice earned their "boarding passes" to space.

By collecting preliminary data on stress responses and adaptation mechanisms in microgravity -- scientists may end up using such observations to decode how weightlessness and enclosed space influence mice behaviors.

After completing their orbital mission, the "mice astronauts" will return to Earth aboard the Shenzhou-20 spaceship for further analysis.

"The findings will be critical to assessing the feasibility of long-term human survival and reproduction in space -- and may also deliver insights beneficial to human health on Earth," Huang said, while noting that the experiment will represent a major step forward in China's space life science research capabilities. ■

JIUQUAN, Nov. 4 (Xinhua) -- Aboard China's space station, the hot air oven delivered by the Shenzhou-21 spacecraft has begun baking, as a viral video showed astronauts savoring freshly cooked chicken wings and steaks for the first time.

In the video beamed down from the space station, Shenzhou-21 crew member and space engineer Wu Fei is seen taking marinated chicken wings from a package, placing them on a skewer rack, and sliding them into the oven, which, after about 28 minutes, produced a plate of sizzling, space-made New Orleans chicken wings.

Wang Jie from the Shenzhou-20 crew and Wu Fei, both hailing from north China's Inner Mongolia Autonomous Region -- renowned for its high-quality beef and mutton -- also baked a plate of black pepper steaks. The chicken wings and steaks were soon shared among the six astronauts, with their faces beaming with delight.

The Shenzhou-21 spaceship was launched on late Friday and its three crew members entered the space station hours later. They have spent several days living and working alongside the Shenzhou-20 crew, who are scheduled to return to Earth on Nov. 5.

The space oven has been significantly upgraded compared with conventional ovens on Earth. According to Liu Weibo from the China Astronaut Research and Training Center, the improvements include technologies for precise temperature control, residue collection, high-temperature catalysis, and multi-layer filtration, enabling smoke-free baking in orbit while meeting the space station's oil fume emission standards.

The oven and its purification system also underwent rigorous testing to ensure they meet the space station's access conditions and can operate continuously and reliably for up to 500 cycles.

Using the oven to prepare food marks the latest advancement in the life support system of China's space station. According to the center, the Shenzhou-21 mission has expanded the food variety to over 190 items and extended the menu cycle to 10 days, allowing astronauts to cook and bake ingredients such as fresh vegetables, nuts, cakes and meat while in orbit.

Liu said that after spending several months in the relatively confined space of the station, being able to enjoy aromatic chicken wings and steaks, or freshly baked peanuts and bread prepared by themselves, would surely bring the astronauts a sense of happiness.

Since China's manned space program entered the phase of space station application and development, ground researchers have continuously improved the variety, texture, flavor, appearance and nutritional value of space food through technological innovation and process enhancements, better meeting the dietary needs of astronauts.

In addition, new progress has been made in the space station's vegetable garden. Since the Shenzhou-16 mission, the center has carried out research and verification on in-orbit plant substrate cultivation. By using regenerative substrate, long-term controlled-release fertilizer and microporous water conduction technology, the garden has achieved effective supply of water and nutrients under microgravity conditions.

So far, 10 batches of seven plant species, including lettuce, cherry tomatoes and sweet potatoes, have been cultivated, providing astronauts with 4.5 kg of fresh fruits and vegetables. Among them, lettuce and cherry tomatoes have achieved a full-cycle cultivation from seed to seed.

"We prepared feasts for the astronauts for traditional Chinese festivals such as the Spring Festival, and there are even gift packages that can only be opened on the day of the festival," said Zang Peng from the center. ■

JIUQUAN, Nov. 14 (Xinhua) -- China's Shenzhou-21 crewed spaceship undocked from the space station combination on Friday and will commence the return mission of sending the Shenzhou-20 astronauts back to Earth, according to the China Manned Space Agency (CMSA).

The spaceship separated from the space station combination at 11:14 a.m. (Beijing Time) and will later re-enter the atmosphere and return under ground command control, with astronauts Chen Dong, Chen Zhongrui and Wang Jie on board.

The Shenzhou-20 spacecraft does not meet the requirements for the astronauts' safe return and will remain in orbit to continue relevant experiments, said the CMSA.

Tiny cracks have been found in the return capsule's viewport window, which are most probably caused by external impact from space debris, according to the CMSA. ■

Kompleksowa analiza symulacyjna, testy i ocena bezpieczeństwa wykazała, jak widać, ryzyko poza wyznaczonymi marginesami bezpieczeństwa.
Wg wcześniejszych informacji moduł kontroli położenia modułu powrotnego, znajdujący się na zewnątrz S-21 uległ drobnej awarii.
Jest to kluczowe urządzenie określające dokładność trajektorii powrotnej.
Mogło okazać się, że system nie jest całkowicie funkcjonalny i działa wadliwie i niemożliwe było jego skorygowanie.

China Focus: China's space station delivers fresh batch of samples for research
Source: Xinhua Editor: huaxia 2025-11-15 14:27:45
   
BEIJING, Nov. 15 (Xinhua) -- The latest samples from 26 scientific experiments conducted aboard China's space station, totaling approximately 46.67 kilograms, were brought back to Earth on Friday, according to the Technology and Engineering Center for Space Utilization (CSU) under the Chinese Academy of Sciences (CAS).

Marking the ninth transfer of materials from the orbiting laboratory, the Shenzhou-21 return capsule brought back samples from experiments in space life sciences, materials science and combustion research.

Upon landing, the mice from the life science experiments underwent immediate field processing. Researchers will analyze their behavior and key physiological and biochemical indicators to understand the animals' stress responses and adaptive mechanisms to spaceflight conditions. These findings will provide critical insights into how space environments affect living organisms, according to the CSU.

Other biological samples -- including zebrafish, hornwort, streptomyces, planarians and brain organoids -- along with select materials science and combustion experiment samples, were transported to the CSU in Beijing at 00:40 a.m. Saturday. After initial status checks, these specimens were handed over to research teams for further study. The remaining samples will be transported to Beijing along with the Shenzhou-21 return capsule.

Next, scientists will perform transcriptome sequencing on the recovered cell samples to investigate microgravity-induced changes, identifying key biological mechanisms and potential intervention targets. This work is expected to contribute to new strategies for preventing and treating related diseases.

For the returned materials science samples -- such as tungsten-hafnium alloys, soft magnetic materials and relaxor ferroelectric single crystals -- researchers will examine their microstructures, chemical composition, and elemental distribution, the CSU said.

These analyses will clarify how gravity influences material growth, composition segregation, solidification defects, and overall performance, while also revealing the in-service performance of materials under space conditions.

The results are anticipated to advance several applications, including protective materials for high-performance solar cells, high-gain radiation-resistant optical fibers, and innovative material processing techniques for lunar infrastructure. These developments would provide important theoretical and technical support for satellite communications and space exploration.

Following the return of combustion experiment samples -- including burners, soot collection plates, and covers -- scientists will analyze the flame-synthesized semiconductor nanomaterials, soot samples, and nanocarbon particle formation characteristics, according to the CSU.

Outcomes from this work may enable advances in extraterrestrial flame synthesis of nanomaterials, new energy systems, fire safety in space, and functional nanocarbon production. ■
