Chinese Astronauts Conduct Radiation Experiment and Achieve First In-Orbit Gas Exchange on Tiangong Space Station

Chinese astronauts have installed a biological radiation exposure experiment outside the Tiangong space station's Mengtian science module. The experiment payload contains 13 sample box units loaded with biomaterials to study the impact of cosmic radiation and microgravity on organisms. The equipment can be used for in-orbit experiments on biological samples, including plant seeds, microorganisms, and small animals. The experiment was developed jointly by the NSSC and Dalian Maritime University and is intended to operate for five years.
