CCTV News: Yesterday (April 16), the Shenzhou 13 manned spacecraft return capsule successfully landed in the predetermined area of the Dongfeng Landing Site. Three astronauts, Zhai Zhigang, Wang Yaping, and Ye Guangfu, ended their 6-month "space trip" and became the astronaut crew with the longest on-orbit mission in my country's history. Today, in our time and space documentary, we will tell
China sent the core module of its space station into a planned orbit on April 29. The space station has a designed lifespan of ten years, but designers believe it could last more than 15 years with appropriate maintenance and repairs.
The space station will face various threats and challenges in the cosmos, such as atomic oxygen, ultraviolet radiation, vacuums, temperature changes, space debris, and microgravity.
These may cause the material performance to decline or induce failures, thus shortening the service life of products and equipment such as extravehicular cables, surface coatings, and optical lenses.
According to Zhou Jianping, chief designer of China s manned space program, maintainability is one of the space station s advantages compared with its predecessors. Maintenance and repairs can ensure the technological upgrade and long-term and reliable operation of the space station.
