However, the exposure experiments can not be free from induced environments. Contamination from the International Space Station (ISS) produced the most readily change to the SM/MPAC&SEED samples, other than natural environments. Since measured characteristics of retrieved materials are affected by both natural and induced environments, it is difficult to investigate the net effect of natural environments. Energetic particles easily penetrate the contamination layer and their effects are maintained. In contrast, contaminant deposition masks the mass loss by atomic oxygen (AO), and contamination discoloration decorates the net change in sample optical characteristics induced by ultraviolet (UV) radiation. This paper was prepared to suggest when, what materials deposited on the samples how much., Physical characteristics: Original contains color illustrations, 資料番号: AA0064307005, レポート番号: JAXA-SP-08-015E}, pages = {27--34}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Contamination effect on SM/MPAC&SEED experiment}, volume = {JAXA-SP-08-015E}, year = {2009} }
