Abstract Macroscopic and microtribological properties of MoS2 films exposed to atomic oxygen, ultraviolet rays and radiation both in low earth orbit (LEO) and in ground-based facility were evaluated. The MoS2 samples are exposed to LEO space environment in the Space Environment Exposure Device (SEED) experiment on International Space Station (ISS). Laser-detonation atomic oxygen beam source was used for atomic oxygen simulation on the ground. It was found that the macroscopic friction coefficient of the flight sample was similar to that of the control sample. In contrast, remarkable increase in friction coefficient in microscopic properties was observed.
