这些“太空特产”从中国空间站而来 期待科学家破解更多“生命之谜”

Core Viewpoint - The successful return of the Shenzhou 19 manned spacecraft marks a significant advancement in China's space exploration, with a focus on life sciences and materials science experiments that could provide insights into human health and future space activities [1][4][11]. Group 1: Life Sciences Experiments - The Shenzhou 19 mission returned with 25 experimental projects related to life sciences, materials science, and new technologies, weighing approximately 37.25 kilograms [4]. - The life science samples include various cell types such as bone cells, bronchial epithelial cells, and fruit flies, which are crucial for understanding human health in space [4][9]. - Experiments conducted on fruit flies in microgravity conditions revealed unique behaviors and successful breeding, contributing to research on human survival and reproduction in space environments [4][11]. Group 2: Materials Science Experiments - The mission also returned 22 types of materials science samples, including high-strength steel and lunar soil reinforcement materials, which will be analyzed for their properties and potential applications [6][13]. - Research on these materials aims to support the development of new high-performance alloys and materials for aerospace applications, such as turbine blades and nano-electronic devices [15][18]. - Over 70% of spacecraft failures are linked to environmental factors, making the study of materials' performance in space critical for enhancing their reliability and durability [17].
