The three-member Shenzhou-23 crew has taken over operations aboard China's Tiangong space station following a smooth handover with the Shenzhou-21 crew. Since arriving on May 25, astronauts Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying have adapted to microgravity and begun their scheduled tasks. Over the coming months, they will carry out more than 100 scientific experiments and projects in life sciences, materials, microgravity physics, aerospace medicine and space technologies.
