SARA仪器（亚keV原子反射分析仪）包括能量范围为10 eV-3.3 keV的低能中性原子（LENA）传感器和离子质谱仪（10 eV-15 keV）。这是有史以来第一个通过测量溅射原子和中和后向散射的太阳风氢来研究太阳风与行星表面相互作用的实验。中性原子传感器利用进入的中性粒子转化为正离子，然后通过表面相互作用技术进行分析。离子质谱仪也是基于同样的原理。SARA执行LENA成像月球的元素表面组成，包括永久阴影区，和月球表面磁异常成像。它还将调查空间风化过程和外大气层气体的溅射源。保留字：
The SARA instrument (Sub-keV Atom Reflecting Ana-lyser) comprises a low energy neutral atom (LENA) sensor for the energy range 10 eV–3.3 keV and an ion mass spectrometer (10 eV–15 keV). It is the first ever experiment to study the solar wind–planetary surface interaction via measurements of the sputtered atoms and neutralized back-scattered solar wind hydrogen. The neutral atom sensor uses conversion of the incom-ing neutrals to positive ions, which are then analysed via surface interaction technique. The ion mass spec-trometer is based on the same principle. SARA per-forms LENA imaging of the Moon’s elemental surface composition including that of permanently shadowed areas, and imaging of the lunar surface magnetic anomalies. It will also investigate processes of space weathering and sputtered sources of the exospheric gases. Keywords:
