A novel concept of γ-ray remote sensing experiment onboard a Mars Rover is considered for studies of Martian shallow subsurface composition with a high spatial resolution. Only those photons produced in reactions of neutron inelastic scattering on nuclei of surface constituting elements are recorded by the proposed gamma-ray spectrometer, which use time tags of particles of Galactic Cosmic Rays (GCR), producing these reactions. It is shown that the composition of the Martian regolith may be determined by this gamma-ray spectrometer with a spatial resolution of meters along the traverse of a Mars Rover.

火星探测器上火星表面成分的伽马射线遥感概念

火星探测器上的γ射线遥感实验的新概念被考虑用于研究具有高空间分辨率的火星浅地下成分。只有在中子非弹性散射在表面构成元素的原子核上的反应中产生的光子被所提出的伽马射线光谱仪记录，该光谱仪使用银河宇宙射线 (GCR) 粒子的时间标签，产生这些反应。结果表明，火星风化层的成分可以通过这种伽马射线光谱仪确定，其空间分辨率为米，沿着火星漫游者的横断面。
