After 55 days of mapping by the High Energy Neutron Detector onboard Mars Odyssey, we found deficits of high-energy neutrons in the southern highlands and northern lowlands of Mars. These deficits indicate that hydrogen is concentrated in the subsurface. Modeling suggests that water ice-rich layers that are tens of centimeters in thickness provide one possible fit to the data.
在“火星奥德赛”号探测器上的高能中子探测器进行了55天的测绘后，我们发现火星南部高地和北部低地存在高能中子不足的情况。这些不足表明氢集中在地下。模型显示，厚度达几十厘米的富含水冰的地层可能与这些数据相符。
