Shenzhou-23 Makes New Progress in Multi-gen Rice Cultivation | China Space Station
The Shenzhou-23 crew aboard China's Tiangong Space Station has made new progress in the country's first multi-generational rice cultivation in orbit, completing a new round of sample collection, sowing, and storage for the groundbreaking space rice research project.
The research project aims to study the molecular mechanisms of the multi-generational genetic stability and environmental adaptability of rice in microgravity. Over the past week, the three astronauts collected a new batch of samples that will be returned to Earth for scientists to analyze at the phenotypic and molecular levels, helping reveal how long-term microgravity affects rice genetic stability.
The crew also conducted touch-interaction tests with their robotic companion "Xiaohang", collecting data on the robot's movements in response to different types of physical contact to improve onboard robot motion planning.
They also completed assessments of emergency decision-making ability and in-orbit emotional state tests, with the data used to study how these change during long-term spaceflight.
In addition, the astronauts carried out data collection for in-orbit exercise research, performed grip strength tests and ultrasound examinations of key anti-gravity muscles, and completed maintenance work on the containerless experiment cabinet.
The crew finished scheduled medical rescue training and a full-system pressure emergency drill, and carried out equipment maintenance, cabin cleaning and regular exercise to maintain good physical and psychological conditions for their stay in orbit.
The three Chinese astronauts—commander Zhu Yangzhu and his crewmates Zhang Zhiyuan and Lai Ka-ying—were launched aboard the Shenzhou-23 spacecraft on May 24, with one of the crew members scheduled to spend a full year in orbit for the first time.
