BEIJING, May 7 (Xinhua) 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.
