If carbon-based molecules exist in the Martian subsurface ice, TEGA will find their organic signatures in the gases.

如果碳分子存在于火星表面的冰里，TEGA就会发现气体里的有机特征。

They interpreted the bright-toned rocks Zhurong's camera caught as a layer of " duricrust" that would have been sculpted by a substantial quantity of liquid water, perhaps rising groundwater or melting subsurface ice.

他们将“祝融号”相机捕捉到的亮白岩石解释为一层“硬壳”，它可能是由大量液态水雕刻而成的，可能是上升的地下水或融化的地下冰。
