Atomic oxygen (AO) is a major threat to satellites in Low Earth Orbits (LEO). AO causes serious damage to satellites such as erosion, corrosion and damage to almost all satellites surfaces. This study presents numerical prediction for the space environment effects on NARSSCube satellite using ATOMOX module in Space ENVironment Information System (SPENVIS) online simulation tools. Indeed, the prediction of erosion yields of NARSSCube structure induced by AO flux in LEO with different models is calculated. NRLMSISE model shows the highest mass and thickness loss for the outer surfaces of the satellite in all worst-case scenarios. A comparative study, for the erosion yields of some materials using SPENVIS, MISSE2 and other calculations, is presented. This research recommends the necessity of developing a database for all materials used in space providing all data for the effect of AO on each material in addition to the erosion depth and mass loss.

原子氧对LEO CubeSat的影响

原子氧 (AO) 是近地轨道 (LEO) 卫星的主要威胁。AO 对卫星造成严重损坏，例如侵蚀、腐蚀和损坏几乎所有卫星表面。本研究使用空间环境信息系统 (SPENVIS) 在线模拟工具中的 ATOMOX 模块对 NARSSCube 卫星的空间环境影响进行数值预测。事实上，计算了不同模型的低地球轨道 AO 通量引起的 NARSSCube 结构侵蚀产额的预测。NRLMSISE 模型显示，在所有最坏情况下，卫星外表面的质量和厚度损失最高。介绍了使用 SPENVIS、MISSE2 和其他计算对某些材料的侵蚀产率进行比较研究。
