Chinese scientists at the CAST have developed a metallic-based thermal-control coating for the SZ-14 crewed spaceship that can protect the taikonauts from extreme heat and cold during their stay in orbit. The new coating works in two ways: providing low solar absorption to help reduce the sun's effect on the spacecraft's internal temperature and providing low infrared emittance to block heat release from internal sources. The thermal-control coating was first used on the SZ-13 spacecraft, which was launched on 16 October 2021. It kept the cabin environment within acceptable temperature ranges (between 18 and 26^oC)
