Surfaces of Solar System minor bodies not protected by atmosphere or 
magnetic field are continuously affected by the interaction with 
micrometeorites, solar wind particles, and high energy particles (Hapke 
2001). The effects induced by these processes are commonly known as 
space weathering. The effects of space weathering can be simulated in 
laboratory. The study of space weathering is essential for the correct 
interpretation of the observed spectral characteristics of small bodies 
of the Solar System, as it was for example in the case of a solution so 
called paradox of chondrites (Strazzulla et al. 2005), or reproducing 
the spectral dispersion slope (in UV) asteroids type S (Hendrix and 
Vilas, 2006 Kañuchová et al., 2015). Direct evidences of the effect of 
space weathering were obtained by analysis particles of the asteroid 
Itokawa brought by Hayabusa probe (Noguchi et al., 2014).
