层层选拔、垃圾收集、营养均衡、漂浮睡觉……中科院专家解读我国首次哺乳动物空间科学实验

Core Points - The article discusses China's first mammal space science experiment, where four mice were sent to the Chinese space station for research purposes [1][2]. Group 1: Experiment Overview - The experiment involves four C57BL/6 mice, known for their genetic uniformity, which are crucial for scientific data collection [1][2]. - The mice underwent a rigorous selection process, including various tests to assess their physical and cognitive abilities, resulting in 100 candidates before selecting the final four [2]. - The selected mice will be monitored for their physiological responses to the space environment, contributing to understanding how living organisms adapt to space conditions [2][3]. Group 2: Living Conditions and Adaptation - The "space small mammal feeding device" was developed to ensure a comfortable living environment for the mice, with controlled temperature, humidity, and oxygen levels [3][4]. - Initial observations indicate that the mice are adapting well to microgravity, displaying active behavior and normal eating habits [3][4]. - The feeding mechanism is designed to accommodate the unique challenges of space, ensuring that the mice can access food and water effectively [4].
