Shenzhou 23 Crew Continues Mission After Over Four Months in Orbit

The Shenzhou 23 crew, comprising astronauts Zhu Yangzhu, Zhang Zhiyuan, and Li Jiaying, has surpassed the four-month mark during their mission in orbit. Over the past week, alongside ongoing scientific experiments and station maintenance, the crew successfully managed the ingress and egress of experimental payloads.

This involved work with external experimental units such as the "Hollow Core Photonic Bandgap Fiber Gyroscope" and "Remote Sensing Target Detection Based on Domestic AI Chip," aimed at testing new space technologies. Materials from an external exposure experiment, launched in November 2022 aboard the Tianzhou 5 cargo craft, were also successfully brought back. This experiment has supported 16 distinct exposure projects across three batches and is currently undertaking its fourth phase.

During their time in orbit, the crew has also advanced several scientific experiments. These include studies on tactile perception and arm vibration to understand changes in astronauts' sensory abilities in space. They have also collected data on emergency decision-making capabilities and in-orbit emotional states, contributing to knowledge about human performance on long-duration missions.

The crew has also been involved in the maintenance of the space station's systems. This included replacing components in the regenerative life support system's water-gas separation unit. Additionally, medical examinations, such as 12-lead ECGs, were performed. Equipment to counteract the physiological effects of microgravity, including bone loss countermeasures and neuromuscular stimulators, has also been utilized.
