ina develops thermal protective coating to protect Shenzhou-14 crew
A team of Chinese scientists has developed
168 slotxoa metal-based thermal control coating. For the Shenzhou-14 manned spacecraft (Shenzhou-14), which will protect the astronauts from extreme heat. and extreme cold during 6 months in orbit
Xinhua News Agency reported from Beijing, China on June 21 that the new coating can be used in two ways: low solar absorption. to help reduce the effects of the sun on the temperature inside the spacecraft and low infrared radiation to prevent heat release from internal sources
Chinese astronauts aboard the Shenzhou-14 spacecraft in orbit, which has been tasked with completing the construction of China's Tiankong Space Station. Many space station elements will be observed during a six-month manned orbit.
baggage handling vehicles and laboratory modules that is docked with the main module of the space station tends to block sunlight As a result, the spacecraft had to experience extreme cold. In the shadow of deep space for a long time while spacecraft still have to deal with extreme heat from direct sunlight in space
If there is no temperature control The temperature of the spacecraft facing the Sun may rise to more than 100 degrees Celsius, while the dark side may drop to -100°C. Create challenges for the health of astronauts. and the operation of spacecraft
Thermal control coating which was developed by the Chinese Institute of Space Technology. It was first deployed in the Shenzhou-13 spacecraft. It was launched into space on Oct. 16, 2021, keeping the cabin environment in the allowable temperature range (18-26 degrees Celsius) during six months of space, which helps astronauts It feels cool and comfortable in the orbiting house.
In addition, China carried out the Shenzhou-14 mission. which consists of 3 astronauts on 5 June ago which prepares the third set of astronauts for the country's space station construction project While in orbit, they will be able to see two laboratory modules: the Tianzhou-5 Carrier and Shenzhou-15. that is docked with the main module of the space station.
