China's Shenzhou-23 crew remained busy aboard the China Space Station more than 400 kilometers above Earth during the Dragon Boat Festival holiday. Over the past week, Zhu Yangzhu, Zhang Zhiyuan and Li Jiaying (also known as Lai Ka-ying) conducted scientific experiments on microbiome and nutritional metabolism, visual motion processing, emotional recognition and emergency decision-making. The crew also carried out station maintenance, in-orbit medical emergency drills and health assessments, including vision, intraocular pressure and fundus examinations.
