一项对美国国家航空航天局（NASA）已退役的洞察号火星探测器的最新数据分析显示，火星地表下可能存在大量液态水。研究人员估计，火星上浸泡在岩层中的液态水，足以创造覆盖整个火星约2公里厚度的海洋。这些水位于火星地壳以下至少11公里深处，目前地球上还没有任何探钻能够汲取那样的深度。科学家表示，这项研究为我们了解火星的水循环提供了线索，也增加了火星上存在生命的可能性。
Original Title: 火星地表下或有大量液态水
Summary: A new analysis of data from NASA’s retired InSight Mars lander suggests that there may be a vast amount of liquid water beneath the surface of Mars. Researchers estimate that the water trapped in rocks beneath Mars could fill an ocean about 2 kilometers deep across the entire planet. This water is located at least 11 kilometers below the Martian crust, and currently there are no drills on Earth capable of reaching that depth. Scientists say this research provides clues about Mars’ water cycle and increases the possibility of life on the planet.
