空间站科学实验样品顺利返回
A variety of scientific experiment samples from China's Tiangong space station have been successfully brought back to Earth. They touched down in the Inner Mongolia Autonomous Region aboard the Shenzhou-21 return capsule after a smooth landing. The samples had been kept on the station for several months.
The returned materials include alloy crystals, plant seeds, and biological cultures. These items were placed in the station’s microgravity environment to observe changes in crystal growth, gene expression, and cell behavior. Scientists hope the findings will help develop advanced materials and improve agricultural productivity on Earth.
