Volume 1, Issue 1 , September 2021, , Pages 135-126

  Space systems in Low Earth Orbit (LEO) are exposed to the destructive parameter of atomic oxygen. In long-term missions, the rate of degradation of the material resulting from the reaction with atomic oxygen is significant and reduces the performance of the structure. Due to the harmful effects of atomic ...  Read More
