Space station experimental samples

A robotic arm on China’s Tiangong space station successfully transferred an extravehicular experiment facility alongside with 407 material samples from outside the station’s Wentian lab module to the station interior on Thursday night.
In order to study the stability, reliability, and longevity of these materials in space applications, the samples were moved outside of the space station on March 8, 2023, to be exposed to the space environment with high radiation levels, high vacuum levels, and wide temperature fluctuations.
According to researchers from the Technology and Engineering Center for Space Utilization at the Chinese Academy of Sciences, the astronauts are scheduled to transfer the retrieved assembly to the Mengtian lab module on Friday.
